You might also want to create your buttons with a loop in your code instead
of in the layout file

Re: [android-developers] button onClick handler retrieve custom attribute value declared in activity_main.xml

[Steve Gabrilowitz]

toString() returns a string representation of an object which is not
necessarily the value of the object.  your view.getTag() returns an object
which is already a String so all you have to do is cast it to string rather
than using toString() on it

String buttStr = (String) view.getTag(); is what you need

All the buttons would share the same onClick handler, where I would use

Dear all,

here is what I want to do : declare a whole bunch of buttons in the

All the buttons would share the same onClick handler, where I would use 
this custom property value to construct some strings (a URL actually).

setContentView(R.layout.activity_main);

public void sendLed(View view){
...
String buttStr = view.getTag().toString();
...
}
}

Now , is that in anyway possible ?
The above construct gets me an NPE.

I am aware that I could use a switch statement (to compare the view.getId()

[android-developers] Button#onClickListener thread unsafe?

[Greenhand]

In my project, I has a layout as follows:
LinearLayout xmlns:android=http://schemas.android.com/apk/res/
android
android:layout_width=fill_parent
android:layout_height=fill_parent
android:orientation=vertical

Button
android:id=@+id/startButton
android:layout_width=fill_parent
android:layout_height=0dp
android:layout_weight=1
android:text=start
 /
Button
android:id=@+id/stopButton
android:layout_width=fill_parent
android:layout_height=0dp
android:layout_weight=1
android:text=stop
 /
/LinearLayout
It is quite simple. There are two buttons. One is start and the other
is stop.

And an Activity as follows:
package button.test;

import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;

public class MainActivity extends Activity {
private static final String TAG = MainActivity;
private Button startButton;
private Button stopButton;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
startButton = (Button)findViewById(R.id.startButton);
startButton.setOnClickListener(new View.OnClickListener() {

@Override
public void onClick(View arg0) {
Log.d(TAG,startButton isEnabled(): 
+arg0.isEnabled()+ executing
on thread + Thread.currentThread().getName());
if(arg0.isEnabled()==false){
throw new 
RuntimeException(startButton);
}
arg0.setEnabled(false);
stopButton.setEnabled(true);
}
});
stopButton = (Button)findViewById(R.id.stopButton);
stopButton.setOnClickListener(new View.OnClickListener() {

@Override
public void onClick(View arg0) {
Log.d(TAG,stopButton isEnabled(): 
+arg0.isEnabled()+ executing
on thread + Thread.currentThread().getName());
if(arg0.isEnabled()==false){
throw new 
RuntimeException(stopButton);
}
arg0.setEnabled(false);
startButton.setEnabled(true);
}
});
}
}
The logic is: (1)When the start button is clicked, disable it and
enable the stop button. (2)When the stop button is clicked, disable it
and enable the start button.

What I expect is that when the onClickListener of a button is
executing, the button state should be enabled. It is impossible to
fire the onClickListener when the button is disabled. Therefore, I add
the if block and the RuntimeException to detect it.

It works when I interact with it but it crashes when I run the monkey
test (adb shell monkey -p button.test -v 5).

The logcat messages are as follows:

Note that at line 4, the button state is disabled when the
onClickListener is executing!!! It is quite strange. In addition, both
the onClickListeners are run on the main thread.

The input events are queued. So your case is valid. When you disable a
button there can be already multiple events in the event queue. Sad
but true :(

  startButton.setOnClickListener(new View.OnClickListener() { 
  
  @Override 
  public void onClick(View arg0) { 
  Log.d(TAG,startButton isEnabled(): 
 +arg0.isEnabled()+ executing 
  on thread + Thread.currentThread().getName()); 
  if(arg0.isEnabled()==false){ 
  throw new 
 RuntimeException(startButton); 
  } 
  arg0.setEnabled(false); 
  stopButton.setEnabled(true); 
  } 
  }); 
  stopButton = (Button)findViewById(R.id.stopButton); 
  stopButton.setOnClickListener(new View.OnClickListener() { 
  
  @Override 
  public void onClick(View arg0) { 
  Log.d(TAG,stopButton isEnabled(): 
 +arg0.isEnabled()+ executing 
  on thread + Thread.currentThread().getName()); 
  if(arg0.isEnabled()==false){ 
  throw new 
 RuntimeException(stopButton); 
  } 
  arg0.setEnabled(false); 
  startButton.setEnabled(true); 
  } 
  }); 
  } 
  } 
  The logic is: (1)When the start button is clicked, disable it and 
  enable the stop button. (2)When the stop button is clicked, disable it 
  and enable the start button. 
  
  What I expect is that when the onClickListener of a button is 
  executing, the button state should be enabled. It is impossible to 
  fire the onClickListener when the button is disabled. Therefore, I add 
  the if block and the RuntimeException to detect it. 
  
  It works when I interact with it but it crashes when I run the monkey 
  test (adb shell monkey -p button.test -v 5). 
  
  The logcat messages are as follows:

   1. Go to File -- New -- Project
   2. In the dialog that opens, Android is one of the options in the list

[android-developers] Button (onClick)

[Алексей Фенев]

https://docs.google.com/drawings/pub?id=18u7ZqCM-13k_OxO3ecm7UXftoWMcBScpGo-wL4WtRjww=174h=76
Hello! When I add an event handler of button onClick, for example: 
android:onClick=click, I get a fail: instead of my widget in emulator I 
have a message Problem loading widget. 
What do you think, how fix it?

Try debugging your app. Look at Logcat, for starters.

Re: [android-developers] button change onClick

[Liem.T Vo]

Please refer at url 
http://developer.android.com/guide/topics/ui/controls/button.html:


I copied from that location for you:

Custom background

If you want to truly redefine the appearance of your button, you can 
specify a custom background. Instead of supplying a simple bitmap or 
color, however, your background should be a state list resource that 
changes appearance depending on the button's current state.


You can define the state list in an XML file that defines three 
different images or colors to use for the different button states.


To create a state list drawable for your button background:

Create three bitmaps for the button background that represent the 
default, pressed, and focused button states.
To ensure that your images fit buttons of various sizes, create the 
bitmaps as Nine-patch bitmaps.
Place the bitmaps into the res/drawable/ directory of your project. Be 
sure each bitmap is named properly to reflect the button state that they 
each represent, such as button_default.9.png, button_pressed.9.png, and 
button_focused.9.png.
Create a new XML file in the res/drawable/ directory (name it something 
like button_custom.xml). Insert the following XML:

?xml version=1.0 encoding=utf-8?
selector xmlns:android=http://schemas.android.com/apk/res/android;
item android:drawable=@drawable/button_pressed
  android:state_pressed=true /
item android:drawable=@drawable/button_focused
  android:state_focused=true /
item android:drawable=@drawable/button_default /
/selector
This defines a single drawable resource, which will change its image 
based on the current state of the button.
The first item defines the bitmap to use when the button is pressed 
(activated).
The second item defines the bitmap to use when the button is focused 
(when the button is highlighted using the trackball or directional pad).
The third item defines the bitmap to use when the button is in the 
default state (it's neither pressed nor focused).
Note: The order of the item elements is important. When this drawable 
is referenced, the item elements are traversed in-order to determine 
which one is appropriate for the current button state. Because the 
default bitmap is last, it is only applied when the conditions 
android:state_pressed and android:state_focused have both evaluated as 
false.
This XML file now represents a single drawable resource and when 
referenced by a Button for its background, the image displayed will 
change based on these three states.


Best regards,
Liem.V

Re: [android-developers] button

Hello,
if you want to just differenciate the button images then use the one xml
and define the two image one for default and one for press and set that xml
as background of button.It will solve your problem ok.

Re: [android-developers] button

[Mark Murphy]

Or take a peek at ToggleButton, or create your own CompoundButton.

BTW, we are assuming that by pressed you mean a persistent status
change (what Android refers to as checked), as in a CheckBox or
RadioButton..

Re: [android-developers] button

[Justin Anderson]

 Sure, in the onPressed event, change the image, when it's not pressed,
 change it back.?


Or you can do it with a selector  If you save the following xml to a
file called btnImage.xml:

?xml version=1.0 encoding=utf-8?
selector
xmlns:android=http://schemas.android.com/apk/res/android;
android:constantSize=true

item android:state_pressed=true
android:drawable=@drawable/pressed_image /
item android:drawable=@drawable/normal_image /
/selector

Then you would just set the image of your button to your selector drawable:

Code: btn.SetImageResource(R.drawable.btnImage);
XML: android:src=@drawable/btnImage

[android-developers] Button in listitem in listview unclickable

[mizyeh]

Hi all,

I found a weird scenario which is button in listitem in listview are
unclickable unless scroll listview to the last listitem,

after some research seems the problem is occurred by the layout
Relativelayout1-Relativelayout2-Listview ,

If you move Listview into the Relativelayout1 it will work fine.

you may see exactly what happens by download this sample project .

Re: [android-developers] Button is not actionable when i set to button background color

[Jason Teagle]

issue is in single alert box we display 16 buttons with different back
ground colors and we handling the listener for getting the  result
which button is clicked(setonclick listener) but button is not
actionable(requirement is Color selector box).


It seems unlikely that just changing its colour would make any difference. 
Try temporarily *not* changing the background colour of the buttons - do 
they now become 'actionable'?


When you say 'not actionable', what exactly do you mean? Do you mean that 
you are not going through your listener's onClick() method? How do you know 
this - have you tried using a quick Toast to prove (or disprove) you are at 
least getting *into* that method? (It may be getting into the method, but 
something goes wrong later in the method and it doesn't complete all the 
actions you are expecting).


Anything unexpected in the LogCat?

If neither of the above quick things help for testing purposes, try 
temporarily creating a new project with one activity and two buttons, set 
one's background colour to yellow and leave the other one with its normal 
colour. Add the listener to both and put a little Toast in the onClick() to 
show it gets that far. If *that* doesn't work, then post the code for that 
*test* project so we can see how you're doing things (one activity + two 
buttons should be a nice, short piece of code).


If the test project works, then it suggests something else in your main 
project is interfering and you'll have to start commenting bits out until 
you find the culprit.

[android-developers] Button Style programmaticaly

[Joel]

Hi,

I am a new Android developer and i have a problem with buttons and
styles.

I have to create buttons with java code and I want set a specific
style.

My code:

in values directory -- styles.xml

?xml version=1.0 encoding=utf-8?
resources
style name=ButtonText
item name=android:layout_widthfill_parent/item
item name=android:layout_heightwrap_content/item
item name=android:gravitycenter_vertical/item
item name=android:layout_margin3dp/item
item name=android:textColor#303a39/item
item name=android:shadowColor#8a9493/item
item name=android:shadowDx1/item
item name=android:shadowDy1/item
item name=android:shadowRadius2/item
item name=android:drawableRight@drawable/icon_button/item
/style
/resources

in Activity I have

private void generateButtons(){
LinearLayout layout = (LinearLayout)
findViewById(R.id.contentLayout);

IteratorLanguage itr = languages.iterator();
while (itr.hasNext()) {
Language l = itr.next();
Button createButton = new Button(this,null,R.style.ButtonText);
createButton.setId(l.getId());

createButton.setBackgroundDrawable(getResources().getDrawable(R.drawable.button));
createButton.setText(l.getName());
layout.addView(createButton);
}
}

In construct I pass the button style but it doesn't work. Any idea?

Thanks.

[android-developers] button click event listener

[Vivek Punjabi]

I am having problem with onclick event listener.I am building a card
game for which i have to wait for button click by the user, after each
round. So I've used a recursive function. My code looks like

oncreate()
{
function1( );
//wait for onclick event
function2( );  //After some calculation, calls function1( )
}

Should I use a different activity or the same one for UI, logic and
click event?
Can u suggest me the structure of my game as I am a newbie in Android
programming?
Thanks in advance

Re: [android-developers] button click event listener

[Justin Anderson]

 oncreate()
 {
 function1( );
 //wait for onclick event
 function2( );  //After some calculation, calls function1( )
 }

That won't work... The UI will not show up until after onCreate() and
onResume() are called.  Why are you explicitly waiting for a click event?
What are you doing to do that, an infinite loop or something?

Can u suggest me the structure of my game as I am a newbie in Android
 programming?

Seems like you need to read up on the Android Activity lifecycle:

[android-developers] Button cannot be clicked when used with an IME

[tsukishiro yamazaki]

Hello everyone,

My custom IME is slowly coming to life! Thanks to all the people who have 
replied to my posts regarding my IME. I hope I can get the same support for 
this question too. So here it is. Up until now, I have been using 
KeyboardView as the root tag in the layout xml for my InputView. Now, I am 
thinking of replacing it with a general View that contains something like a 
RelativeLayout and several buttons. Inflating the layout and getting it 
displayed as my new InputView for the IME have no problems. But when I try 
to click on any of the buttons in the new InputView, it seems I cannot fire 
any click event at all. 

Does anyone know how to resolved this problem? 
Hoping for your support. Thanks and best regards,
- tsukishiro

View button = (View)findViewById( R.id.my_button );
button.startAnimation( AnimationUtils.loadAnimation(
R.anim.anim_for_my_button ) );

you can safely stick to View instead of i.e. ImageButton in case of
applying animation.

[android-developers] Button for dynamic text

[Pram]

I am writing a program that when the user enter a number text appears
according to that number. My problem is that the button line has
public void ... after this I am trying to use if statements and return
methods, but because of the public void, the return method can not
return anything. I tried to close the public void, but I am getting
errors. Please help. The code is as follows. I have included the
different codes that I have tried like toast, etc..

ente@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
  Button button = (Button)findViewById(R.id.go);
  button.setOnClickListener(mAddListener);

//  tv = (TextView) findViewById(R.id.textView1);
}

private OnClickListener mAddListener = new OnClickListener()
{
public void onClick(View v) {
}}
;
//Toast.makeText(Num.this, This Display,
Toast.LENGTH_SHORT).show();
//toast.show();
//finish ();
//  long id = 0;

// try { PleaseEnter=(EditText)findViewById(R.id.PleaseEnter);

  {
  }

  if (PleaseEnter.equals(1))
 // tv.setText(This is the display 1.);
  return This display;

   //   Context context = getApplicationContext();
 // CharSequence text =this display;
 // int duration =Toast.LENGTH_LONG;
 // Toast toast =Toast.makeText(context, text, duration);
//toast.show();
else if  (PleaseEnter.equals(2))
return;
//tv.setText(Dispaly 2);

How well do you know Java? It sounds like you're getting hung up over
language syntax and semantics. If that's the case, you need to brush up on
Java, which is off-topic for this list.

Button
android:layout_width=179dp

android:layout_centerHorizontal=true
android:background=@drawable/bg_act_incall_actions_end_call
android:text=End Call
android:textAppearance=@style/TextInCallEndCallButton

and a TextInCallEndCallButton style:
style name=TextInCallEndCallButton
item name=android:textSize20sp/item
item name=android:textColor#ff/item
item name=android:textStylebold/item
/style
The button color (the text) will stay BLACK.
Now, when I'm setting android:textColor directly on the Button, it
works.
So, supposed textAppearance is not working, the button label would
still be BOLD and in the specified size of 20sp.

I just want to know why the textColor in textAppearance is not work...

[android-developers] Button clicking colour change problem

[B.Arunkumar]

Hi,

I am having problem with colour change of 2 buttons:

This is a simple code that I tested out on a device:

 button1.setOnClickListener(new OnClickListener(){

@Override
public void onClick(View v) {
// TODO Auto-generated method stub

try {
Thread.sleep(15000);
} catch (InterruptedException e) {
// TODO Auto-generated catch 
block
e.printStackTrace();
}
}

});



   button2.setOnClickListener(new OnClickListener(){

@Override
public void onClick(View v) {
// TODO Auto-generated method stub

try {
Thread.sleep(15000);

} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

});

When I click on button1 and (while this is executing) click on button2
and back to button1, both button1 and button2 appear coloured blue.
Why is this happening? The colouring of the 2 buttons should appear
sequentially because button clicking happens on the main thread, is it
not?

(Actually, I posted the same question on an earlier thread too but I
have not been able to figure out why this is happening)

Thank you,
B.Arunkumar

 Hi
 I was trying to arrange 9 Buttons in TableLayout.(main.xml below)

 On the eclipse Graphical Layout, it looked ok, Buttons spaced out
 nicely. Somehow on the emulator, all the 9 Buttons looked joined

 Here's the screenshot:

[android-developers] Button not excepting typeface

[Raghav Sood]

Hi all,

I was updating the ui to one of my apps, and encountered a problem setting
the typeface of the button. According to the online docs, calling
setTypeface() on a button should work. However, I get the following error:

[android-developers] Button lick problem

[B.Arunkumar]

Hi,

  I have a problem with button click. This is what I have written in a
sample Activity:

 button1 = (Button) findViewById (R.id.button1);
 button2 = (Button) findViewById (R.id.button2);

 button1.setOnClickListener(new OnClickListener(){

@Override
public void onClick(View v) {
// TODO Auto-generated method stub
try {
android.util.Log.e(Button1, 
clicked);
Thread.sleep(15000);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

});

 button2.setOnClickListener(new OnClickListener(){

@Override
public void onClick(View v) {
// TODO Auto-generated method stub

try {
android.util.Log.e(Button2, 
clicked);
Thread.sleep(15000);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

});

This is what happens (We tested the application on Samsung Galaxy).
When we click on Button1 and then Button2 and button1 again, we see
that both button1 and button2 have changed theiir color to blue
simultaneously. Why is that the color of both the buttons change
simultaneously? As per this link:

http://android-developers.blogspot.com/2009/05/painless-threading.html

the button click event happens on the same main UI thread. In that
sense, both the buttons should not have changed their colors
simultaneously.

Thank you,
B.Arunkumar

Re: [android-developers] Button lick problem

[Mukesh Srivastav]

Arun,

I am not sure what is the purpose of going to sleep mode, and secondly you
put a logs on the other abstract methods of your activity class. I would
suggest read the Android life cycle as well.

[android-developers] Button Animation

[F4L|{0]

hi
I have a problem with an animation of a button.
I would move and fade a button from a origin position to another
position. well i created a translate animation and fade animation, i
start the animation with the follow code:

AnimationSet exchangeAnimation = new AnimationSet(true);
exchangeAnimation.setFillAfter(true);
exchangeAnimation.setAnimationListener(new AnimationListener() {
  public void onAnimationStart(Animation anim)
{button.setEnabled(false);}
  public void onAnimationRepeat(Animation anim) {}
  public void onAnimationEnd(Animation anim) {
  button.setEnabled(true);}});
exchangeAnimation.addAnimation(AnimationHelper.fadeAnimation(0,
1, 2000));
//i valori passati come fromX, toX, fromY e toY sono dati da un
rapporto e vanno da 0.0F a 1.0F
//quindi bisogna calcolari come pos voluta / width screen o
height screen

exchangeAnimation.addAnimation(AnimationHelper.translateAnimation(0.0F,
0.5F, 0.0F, 0.5F, 1500));
button.startAnimation(exchangeAnimation);

So, my problem is that while the button moves to the position that I
want, the hit area remains at the point of origin.

somebody can help me on how to correctly position the hit area of the
button?

AFAIK, animations only make it look like an object is moving / scaling /
whatever. The actual position / size / whatever of the View in unchanged. If
you want the position to update, manually update it when the animation is
finished.

[android-developers] Button in Custom Preference gets enabled automatically

[KK]

I have a custom preference in my application which consists of a
textview and a button and it is put in a preference screen. I load the
layout in the onCreateView of the preference

LayoutInflater inflater =  (LayoutInflater)getContext().
 
getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View view = inflater.inflate(R.layout.custom_preference, parent,
false);

In my xml, I have put android:enabled=false for the button because I
want to disable it and enable it conditionally later. When my
preferencescreen comes up, this button is disabled, but gets enabled
automatically in a second(I still haven't added any code to enable
this yet).

Also I find that the onCreateView of my custom preference keeps
getting called again and again.

Can someone please help me as to what is happening here?

[android-developers] button id causes app to crash

[DB12]

Howdy, I searched for about 30 minutes to see if anyone had the same
issue but couldn't find anything.

I have a custom dialog I created with a relative layout, when the user
clicks on a button it brings up the dialog just fine normally.  I
added a few buttons to the dialog layout and this is where the trouble
begins. For some reason when I add an id to the third button, my I get
a runtime exception/force close dialog when my app starts up.  If the
third button has no id, the app works fine.  The other two buttons
already have id's and work great.
so in summary...

this layout works fine
?xml version=1.0 encoding=utf-8?
RelativeLayout xmlns:android=http://schemas.android.com/apk/res/
android
android:layout_width=fill_parent
android:layout_height=fill_parent
Button
android:id=@+id/cancel
android:layout_width=wrap_content
android:layout_height=wrap_content
android:layout_alignParentRight=true
android:text=Cancel /
Button
android:id=@+id/line
android:layout_width=wrap_content
android:layout_height=wrap_content
android:layout_alignParentLeft=true
android:text=Line /
Button
android:layout_width=wrap_content
android:layout_height=wrap_content
android:layout_toRightOf=@id/line
android:text=Vehicle /
/RelativeLayout


and this one gives me a force close runtime exception when my app
starts
?xml version=1.0 encoding=utf-8?
RelativeLayout xmlns:android=http://schemas.android.com/apk/res/
android
android:layout_width=fill_parent

this is the only difference between the two

[android-developers] Button add programmatically not clickable

[deveLoper]

Hi,
I need to add some of my buttons programmatically since the titles are
coming from a database that may change. The buttons are being add
fine, but are not clickable. I am using a custom background for the
buttons, but I am using the same background for some button I am using
from xml and they work find. If I add the line
countybutton[i].setFocusableInTouchMode(true); , the button can focus,
but doesn't click. I also tried to set it clickable, but it didn't
work. Here is my code:

res = getResources();

button_background = res.getDrawable(R.drawable.custom_button_gray);
context = getApplicationContext();
float scale = context.getResources().getDisplayMetrics().density;



for(int i = 0; i  county.size(); i++){
countybutton[i] = new Button(this);
countybutton[i].setText(county.elementAt(i));
countybutton[i].setBackgroundDrawable(button_background);
countybutton[i].setLayoutParams(new 
LinearLayout.LayoutParams((int)
(85*scale),
LinearLayout.LayoutParams.FILL_PARENT));
countybutton[i].setTextColor(Color.WHITE);

I would ask you a question: why insert the botton back home in your app
when devices have a dedicated Home button??

[android-developers] Button in a ListView cell

[Eric]

I have seen dozens of posts about people trying to put a clickable
Button in a ListView cell, along with other text, and apparently
nobody has been able to get it to work.

Here is what I need to do:

1. Have a couple of TextViews in a ListView cell, with a clickable
Button on the right-side of the cell.

2. When the user clicks in the cell outside of the button, I should
receive the click in OnItemClicked (which will navigate me to another
Activity).

3.  When the user clicks on the Button in the cell, the Button's
onClick() should be executed and some other operation will be
performed.

4. This has to work for both Touch input, and trackball/D-pad input.

5. This cannot interfere with the ListViews selector highlighting such
that when I use the trackball-DPad to navigate the ListView, the
selected cell should be highlighted.

I just can't get this to work.  I've tried many permutations of many
approaches, but one of the above items stops working in each of the
cases.  Can anyone please tell me the best/correct way to achieve
this?

- Eric

Create object of Button class and add it to your layout. All is in
documentation. All you need it is to read it.

Re: [android-developers] Button and onClickListner help needed

[Justin Anderson]

Have you verified you are not getting in the onClick method?  Try putting a
Toast inside your onClick method and see whether or not you are getting in
there...

I don't see anything wrong offhand with your onClickListener...

[android-developers] Button text padding changes when text changes

[Zarah]

Hi guys,

I have encountered a weird occurrence with Buttons and I hope someone
can explain to me why it is happening.

On load of my activity, my Button has default texts set in it. When
the user clicks on one of them, the Button's text changes. When I test
my app on small screen devices, the bottom part of the default text is
cut off for letters with hooks like j, p, y, g. But when the
button's text changes, the letters are not cut off.

According to my investigations, the top padding for default texts is 8
pixels. When the text changes, it becomes 6 pixels. I don't change the
padding before changing the text, so why does this happen?

Thanks in advance.


- Zarah.

The likelihood of anyone here not only having the code to solve your exact
scenario (which you did not clearly explain) but also being willing to just
give you said code is very near zero.

You would be better served by posting the stack trace of the error and the
snippet of code for where it occurs.

[android-developers] Button color - StateListDrawable question

[AUandroid]

I am allowing the user to change the color of the buttons. I want to
maintain the default drawables used for focused and onPressed state
and apply the color only when the button is neither  pressed nor
focused.

I am currently achieving this by checking the state of the view in
onDraw() on the button class and apply the color filter if it is
neither pressed or focused, else I am passing null to color filter.

Is there any easier way of doing this? Is there a way to get the
default StateListDrawable of the button and change only the desired
state drawable. I have too many views in my layout and I am trying to
reduce any work done in onDraw method as it is slows down the
layout.Thanks

Re: [android-developers] Button color - StateListDrawable question

The StateListDrawable and nine-patch PNG resources used by a Button
are in your SDK. Copy them into your project and modify to suit.

[android-developers] Button placement problems

[Serdel]

Hello,

I could find anything similar so I decided to open a new thread.
However if there already is a similar answer please post the link.

I need to place my buttons in a little unconventional way shown here
(dkw I could post the message with an imageshack link so an ASCI
'picture'):

___
||
||
||
||
||
||
|__|
|___B1_|
||
|    |
|___B2___|_|___ B3__ |

In fact I need it working in a second screen without B2.

So far my code is the following:

?xml version=1.0 encoding=utf-8?
LinearLayout
android:id=@+id/layout1
android:layout_width=fill_parent
android:layout_height=fill_parent
xmlns:android=http://schemas.android.com/apk/res/android;
android:background=@drawable/id_app2 android:orientation=vertical
android:gravity=fill

Button android:id=@+id/button1
android:layout_width=fill_parent
android:layout_gravity=center_vertical
android:layout_marginTop=291dp
android:layout_height=40dp
/Button

Button android:id=@+id/button3
android:layout_width=wrap_content
android:layout_height=wrap_content
android:height=30dp
android:width=160dp
 android:layout_gravity=bottom|right
android:layout_marginTop=70dp
/Button
/LinearLayout

(for simplicity I have removed the B2 from the code) An it worked on
my Samsung Galaxy. However I tried the same app on my friends acer
phone and the buttons were higher that should be. This is a little bit
strange since everything on other screens works fine (as you can see I
use dp not px) - I only have problem with this one. How to place them
so they would be the same at every device?

PS: For clarity B1 is a  below the center of the screen.

Serdel,


Please note that you set B1 to be centered_vertical and have
top_margin of 291dp.

Which Acer phone you tested this on and the result was not the same?
Do you need the space between B1 and B2, B3?

OK ... this is pretty broad. What do you have working so far? Where exactly
are you having trouble?

[android-developers] button on screen that controls page sliding

[timecatcher3]

Hi,

I am new to android development. I wanted to make a button on one of
my activities that I can drag to slide my current activity page to the
next activity page. The button will be in the center of the screen and
I want to be able to press and drag it horizontally to one end of the
screen while I am dragging my button I can see my current activity
page moving. It is actually like when one slides on the home screen
and can control the sliding depending on how far he slides his finger
on the screen.

Thanks,

Re: [android-developers] button click

[Jayu Sagar]

Hi joy ,
what you can do is get all the text views in your activity by using the
Findviewbyid.

when clicked the button you can do get text from the First textView and
Second textview and keep Toggling it :) hope it was informative.



Jayu.

Your question is difficult to understand. You should try to clarify and

Re: [android-developers] button click

[Filip Havlicek]

I'm going the crystal ball way here.

You need to take the current content of text view (or save it somewhere) and
when you press the button next time, take that content (or it's id or
something like that, really depends on what you are trying to do and how)
and then select next content based on current one. If you are trying to
show, for example, tags from your xml, I would suggest parsing the whole
file on first button press and save the tags along with their ids
(reflecting their position in the file), then just selecting next id on next
button presses.

Best regards,
Filip Havlicek

[android-developers] Button organisation

[Laurent Lugon Moulin]

Hi all,

I want to put three buttons in one single line with the left and the right
button at a fixed size, and the middle button wich take the distance between
the two buttons. My application will work in different device, so I can't
fix the size, it has to be adaptative...

Here is my current code :

RelativeLayout android:layout_height=wrap_content
android:layout_width=fill_parent
android:orientation=horizontal
android:gravity=center

Button android:layout_width=70dp
android:layout_height=wrap_content
android:text=@string/lbl_help
android:gravity=center
android:background=@drawable/btn_grey_9p
android:textColor=#cc
android:textSize=18dp
android:layout_margin=1dp
android:layout_alignParentLeft=true/

LinearLayout android:layout_height=wrap_content
android:layout_width=wrap_content
android:gravity=center
android:layout_centerInParent=true

Button android:id=@+id/btnApply
android:layout_width=140dp
android:layout_height=wrap_content
android:text=@string/protect_me
android:gravity=center
android:background=@drawable/btn_bottom
android:textColor=#ff
android:textStyle=bold
android:textSize=18dp
android:layout_marginTop=1dp/
/LinearLayout

Button android:id=@+id/btnLocate
android:layout_width=70dp
android:layout_height=wrap_content
android:gravity=center
android:background=@drawable/btn_bottom
android:textColor=#ff
android:textSize=18dp
android:text=@string/btn_locate
android:layout_margin=1dp
android:layout_alignParentRight=true/

/RelativeLayout

For the moment, the size is fixed (in red in the code). If I use a
LinearLayout, with the middle button widht parameter :
'android:layout_width=fill_parent' It start at the right of the left
button (OK) but overwrite the right button (NOT OK)

Anyone can help me ?

Re: [android-developers] Button organisation

[Mark Murphy]

Step #1: Get rid of the LinearLayout, since you do not appear to need it

Step #2: Get rid of the android:orientation=horizontal from the
RelativeLayout, since orientation is not a valid attribute for
RelativeLayout

Step #3: Give your first Button an android:id value, so we can refer
to it from within the XML

Step #4: Have your middle Button anchor itself to the other two
(android:layout_toRightOf=... and
android:layout_toLeftOf=@+id/btnLocate)

Step #5: Remove the + sign from @+id/btnLocate in the last Button,
since ideally you only use the + sign on the first occurrence of the
ID value in the layout file, and step #4 refers to btnLocate first

Re: [android-developers] button focus

[Kumar Bibek]

Look at the state list drawables. Buttons and other widgets have a default
statelist drawable. If you are using your own drawable, (just a image), the
button doesn't know what to show when in different states. Rather than
setting a drawable(picture) as a background, you should be using a state
list drawable which specifies which images to use for different states.
