[android-developers] Re: view elements unintenionally blinking
Found the reason for blinking views: the top RelativeLayout collided with
the ActionBar, which is automatically added to the layout since Honeycomb
and has effect even if it is not visible. Although I do not understand
what's really going on, I found a way to get rid of the ActionBar, as not
needed (by googeling of course).
Here is the solution, that makes it disappear and also works for older
versions of Android that do not support ActionBars.
In the Activity hosting my SurfaceView I modified:
@Override
public void onStart(){
super.onStart();
if(Build.VERSION.SDK_INT = Build.VERSION_CODES.HONEYCOMB){
ActionBar actionbar;
actionbar = getActionBar();
actionbar.hide();
}
...
}

Hi All,
on my Android Tab (TF 101g with keyboard dock, Android 4.03)
I observe some strange blinking I cannot explane.
The whole screen is being controlled by a Relative Layout containing
another Realive Layout with some view elements on top position, followed by
a SurfaceView with a grafic canvas and below that some other views, one of
them an EditView for number entry.
When I run my application on that device being undocked, i.e. without the
hard keyboard, and hold it in landscape orientation, first the soft
keyboard appears and all view elements get shifted topwards. Then, after I
closed down the keyboard, all view elements return to their original
position, *while those within the RelativeLayout above the SurfaceView
start blinking continuously*.
Even Part of the application title and Icon get overwritten in black an
reappear on a half second rate.
When I replugg the device into the keyboard dock, blinking stopps
immediately.
Neither does this occur, when I hold the undocked device in portrait
orientation.
There seems to be a certain dependency on the EditView below the
SurfaceView. At least the blinking rate goes down, when this is disabled.
I have the same application running on a smart phone (Alcatel OT918D,
Android 2.3.6) and there is no such issue at all.
(On the smart phone the EditView is not visible in landscape orientation,
because it does not fit within the display. Is this of any importance at
all?)
The containing views xml-file is attached.
Any helpful hints gratefully apreciated

It may be easier to do this programmatically. You can build your bitmap image first, figure out the dimensions of that and resize it if needed. Then, change the dimensions of the TextView, if necessary, to match the size of the image, probably using LayoutParams. Finally, you can set it as the background of the resized TextView as the resized image. -John On Wednesday, February 29, 2012 6:51:40 AM UTC-5, Reddy wrote: Hi Moktarul, Still i am facing the same problem.

Great, thanks.
You're right that it tripped me up because it wants this constructor:

It works now that I put it in.

The problem was in my widget, I had the correct constructor (Context
context AttributeSet attr); HOWEVER - super(context) was being called
- not super(context, attr). Once I fixed that, life was better.

[android-developers] Re: view in background receiving input
An app I'm currently developing shows strange behaviour: a view in background receives input. In a FrameLayout, I put a view on top of another (detail view open when an item of a list is selected). Visually, everything looks as expected. But when touching anything with the detail view in foreground, events of the list in background are triggered (which means that another detail view opens on top of the first one, and then another one etc.). Try setting android:clickable=true and/or android:focusable=true on the top view. Pent -- You received this message because you are subscribed to the Google Groups Android Developers group.

That's a bad snippet, but their site's login seems broken. I would avoid using wildcard MIME types for specific files like this. For example, there might be an audio player that only handles OGG, not MP3 -- the ACTION_VIEW shown here would still offer that OGG-only player as an option, which would then break. For selection Intents, like an ACTION_GET_CONTENT, wildcard MIME types are fine, AFAIK. But for cases like this, I would use the fully qualified MIME type, sans wildcard.

[android-developers] Re: View width and calculated text width doesn't match
Does it work on stock Android, like the Nexus One? If you want to send me your .apk, I'd be happy to try it for you. On Dec 15, 12:45 am, Schoel samuelsson.j...@gmail.com wrote: Hello, I am trying to create a view that fits a text into a given text view. I've done a new view that has a custom XML attribute called minTextSize that is a dimension. Whenever text is set on the text view, it tries with all sizes from the desired (specified in the xml) down to minTextSize until it finds one that fits. This works perfectly on an emulator, I get the desired behaviour but when I try it on my HTC Desire, the calculated text width and the calculated width of the text view doesn't seem to match. I've tried both Paint.measureText, Paint.getTextWidths and Paint.getTextBounds, all with the exact same result. Around 9 characters fit in the view but I have to write around 18 characters before it starts making the font size smaller. I use View.getWidth to measure the width of the view and it seems to be correct since it claims to take 392 pixels out of the 480 available (which looks about right). The only thing I can think of is that measureText and getWidth uses different units. Could that be the case? Do you have any other ideas for me? I've tried Stack Overflow and all answers I've seen uses one of the three methods in Paint mentioned above.

[android-developers] Re: View width and calculated text width doesn't match
I can provide some additional information here: m_TestPaint = new Paint(); m_TestPaint.set(getPaint()); m_MaxTextSize = getTextSize(); m_TestPaint.setTextSize(m_MaxTextSize); Log.e(FintFit, Paint text size: + m_TestPaint.getTextSize()); Log.e(FintFit, Text text size: + getTextSize()); This outputs 42.0 and 63.0 respectively. That doesn't seem right, does it? Why isn't the Paint respecting the size I set to it? Zsolt: Thanks for the offer but I can't send you my .apk as this code is part of a closed source project.

[android-developers] Re: View background color animation
Thanks, for the lead. I appreciate it, and it worked. I ended up
extending the TransitionDrawable class so I could easily set and
animate the color. The code is below for anybody who is interested.
package com.digitalagua.view;
import android.graphics.drawable.ColorDrawable;
import android.graphics.drawable.Drawable;
import android.graphics.drawable.TransitionDrawable;
public class BGColorTransitionDrawable extends TransitionDrawable {
private int interval;
public BGColorTransitionDrawable(Drawable[] layers) {
super(layers);
interval = 500;
initVars();
}
public BGColorTransitionDrawable(Drawable[] layers, int interval) {
super(layers);
this.interval = interval;
initVars();
}
private void initVars(){
setCrossFadeEnabled(true);
setId(0,0);
setId(1,1);
}
public void changeColor(int color){
setDrawableByLayerId(0, getDrawable(1));
setDrawableByLayerId(1, new ColorDrawable(color));
startTransition(interval);
}
}
I set and call it like so.
ColorDrawable layers[] = new ColorDrawable[2];
layers[0] = new ColorDrawable(0xffff);
layers[1] = new ColorDrawable(0x);
backgroundColorAnimation = new
BGColorTransitionDrawable(layers);
vColorSwapper.setBackgroundDrawable(backgroundColorAnimation);
backgroundColorAnimation.setColor(0xff00ff00);
Thanks again,
James

[android-developers] Re: View after ListView does not show up
I have a problem to display the view (e.g. Button after the ListView which I will bind and populate from a CursorAdapter). snip The list displays perfectly, however, the button at bottom never shows up.. If I put the button on top of the list, it works fine. Have you tried putting a specific height on the ListView, or on the LinearLayout that contains it? Anyone know the reason? I'm just guessing here, based on what I've run into. ListView does not play well with wrap_content, either on itself or on parent containers (e.g., your LinearLayout), since the content is indeterminate at layout time. It'll tend to grab whatever space is available, and tell its parents to grab whatever space is available. And, since Android takes a single pass through the layout files, the ListView will tend to slurp up all the available space before later widgets, like your button, get their shot. So you wind up needing explicit height control, such as a specific pixel height on the ListView or one of its parents. I haven't played with android:layout_weight in this scenario, to see if it could be used to better manage the ListView's height. But that might work. Or, you can always calculate the height yourself in onCreate() and adjust it as needed, if your attempts to constrain it leave you with improper dimensions on some device resolutions. Or, just have your ListView be the last widget in the chain (e.g., put the button above it). Or, dump the other widgets and just have the ListView, using dialogs or secondary activities or ViewFlipper or tabs or something for the other user input. I'm actually not a big fan of mixing ListViews and much else on an activity, mostly because we're going to wind up with some mighty small screens (e.g., 240x320 on a flip-phone-sized display), and non-touch-screen devices to boot, and so the more complicated we make our UIs, the more difficult they will be for many users to use. They might be...ummm...dreamy in the immediate term, but they'll pose problems over time as Android gets used in many other form factors. A fine example of this philosophy is the preferences activity. Everything is either something trivial for a single row (e.g., checkbox) or goes into a dialog. -- Mark Murphy (a Commons Guy) http://commonsware.com _The Busy Coder's Guide to Android Development_ Version 1.2 Published! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: View cant accept key event ?
A View can certainly receive key events, that is how most key processing (center pressing in buttons, navigating in lists, entering text in text views) works. To receive key events, a view does need to have focus. This will happen for you through the normal focus navigation, or you can explicitly request focus with View.requestFocus(). See the Focus Handling and other sections of the view doc for more info: http://code.google.com/android/reference/android/view/View.html On Aug 15, 1:03 am, Wlliam.Zhang [EMAIL PROTECTED] wrote: hi, I overrided the onKeyDown method of a class inherited form View, but it seems the key event cant posted to the view object at all, I have tried to focuse/selecte the view but all failed.

[android-developers] Re: View Activity Communicaton
Once again thank you for the feedback.
I would then suggest for someone to review the examples, since I'm 99%
sure that I got the Application suggestion, from an Android
Documentation example, I just can't pin point it right now.
Currently, it's working a lot better and faster, by using activity,
and start subactivity, since it's not launching a new Task everytime.
The make your view an inner class of activity suggestion, doesn't
work when we want to reuse a view, but for the other more common cases
it's fine, althought currently all my views are not inner classes (I'm
passing the activity, so no problem their now).
By the way, once we launch the application we get a Dark Grey Back
ground, with a Title on top, stating our application name, has defined
in the AndroidManifest.xml file and res/values/strings.xml, which is
perfectly fine.
However, all my Activities are setup so that I don't get a title or
even a status bar at the top, by having startup code in onCreate like
the following:
/** Called when the activity is first created. */
@Override
public void onCreate( Bundle icicle )
{
super.onCreate( icicle );
// We do NOT need a title.
requestWindowFeature( Window.FEATURE_NO_TITLE );
// remove status bar, to get FULLSCREEN
getWindow().setFlags(
WindowManager.LayoutParams.NO_STATUS_BAR_FLAG |
WindowManager.LayoutParams.LAYOUT_IN_SCREEN_FLAG,
WindowManager.LayoutParams.NO_STATUS_BAR_FLAG |
WindowManager.LayoutParams.LAYOUT_IN_SCREEN_FLAG );
setContentView( new AppView( this ) );
...
}
Is there a way to avoid the Dark Grey background while the application
is starting, like setting up a layout.xml or similar, so that we get
either a predefined background or at the worst case a full Black
background while the application is loading ?
I have tryed using a loading something similar to a splash screen,
whcih loads faster, but I always get the dark grey background with
title to pop up before actually loading the first activity.
A hint for getting rid of this would be great !
Once again, thank you for the feedback.

[android-developers] Re: View Activity Communicaton
Possibly an important piece of information that I haven't mentioned before. I'm NOT using the available Android widjets, like buttons and similar, to avoid GUI problems between SDKs, specially since the application is a game, and is NOT common to use the phone OS GUI inside a game. Games usualy provide a GUI interface of their own, in order to be able to control all aspects of the Graphical Interface. So, I'm drawing all my View contents, using Drawables, and processing the onKeyDown and onMotionEvent/onTouchEvent inputs myself. And obviously I'm not setting these view components through androidManifest.xml. I only declare my Activities there and that's it.

[android-developers] Re: View Activity Communicaton
Thanks a lot dor the input. From all that was said, I believe that I may be feeding the View Constructor with something else than the activity, probably something like Application or similar, I know I copied one example from the SDK, if I'm not mistaken, I'll have to check when I get back home. But having to force a cast on the context given to a view, just to be able to call the methods from the activity on the same context, seems like a hack to me. Probably better than what I'm doing know (forcing the flag NEW_TASK_LAUNCH). But this probably hints that something must be changed in the interface between an Activity and a View. Since, the need to force casts to input of an API, is usually sign of a not so good solution. Food for tought, probably. Is this Activity - View communication model, by any chance already being review for future versions? If Yes, any info on it, that could be advanced before hand ? Thanks a LOT for the prompt feedback.

[android-developers] Re: View Activity Communicaton
I had this exact question a while ago, when I was building some custom
View components. What I wanted was a little more complicated though -
it was basically this.
Basic containing view, set in the Activity class itself
Several classes stored inside the activity with views defined *inside
those classes*
I needed these external views to be able to launch subactivities and
deal with the return codes themselves.
At first this seemed kind of nasty, because the functionality I wanted
for my non-activity view classes is *only* available in an activity!
The solution, as it turns out, was pretty simple - define your own
constructor for those classes, and pass in the activity. Then you can
just call whatever you need to on it. It works like this:
public class MyActivity extends View{
private final Activity mActivity;
public MyActivity(Activity a){
super(a); //since Activity extends context, this works just fine
mActivity = a;
...
}
@Override
public void onClick(View v){
...
mActivity.startSubActivity(...);
...
}
}
Dealing with the return codes was a little trickier, but it doesn't
sound like that's what you need right now. If it is, just ask. :)

Probably better than what I'm doing know (forcing the flag NEW_TASK_LAUNCH). Well, you have a range of choices: - Using NEW_TASK_LAUNCH like this is fundamentally broken (unless that is the semantics you really want)/ - Performing a cast is a quick and dirty style that you can use when you know exactly how your View class will be used. - You can give an explicitly Activity object to the view, which allows the view to work in all situations though it may be awkward to hook things up. - Or you can have a formal callback interface from the view, like the various ones used in the platform frameworks, which is the cleanest approach. But this probably hints that something must be changed in the interface between an Activity and a View. Since, the need to force casts to input of an API, is usually sign of a not so good solution. No, this is intentional. A view may very well not be running inside of an activity. For example, it could be put in a dialog, in which case there is no activity to finish. Is this Activity - View communication model, by any chance already being review for future versions? If Yes, any info on it, that could be advanced before hand ? We don't expect any major changes to it. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: View Activity Communicaton
Another Example: How do we call our activity finish method, from our activity view class ? Inside an Activity context, we can just call finish(); Inside a view, apparently we can't get a reference to the Activity that contains us (the view), and even if there is a way to get the reference, we can't probably call it directly, due to UI threading issues. So, do we send a message ? How ? How do we get the reference to the Handler defined inside our Activity, to be able to call myHandler.sendMessage(...) ? I think the UI handling code is complex and cumbersome to work with. I agree that probably should use messaging, since this helps to decouple the several application parts, but the current API, is not very helpful, in making the common message usage simple. Any help on this would be great too.

The whole design on this communication is fuzzy at least for me. NOTE: using M3 currenlty. Examples: Activities can have menus, creating when onCreateOptionsMenu( Menu menu ) is called Later we can get the menu selection by implementing onOptionsItemSelected( Menu.Item item ). So, inside and Activity, we have access to user actions/input in the form of a menu, and hence we can react to it, for example, by launching another activity (typical usage). This works, because we are in the context of the activity. NOTE: This is what I'm using now, so that I could keep on developing until I find a solution to my problem (next). Now if, you look at the View object, it's the only one to have user input handlers, like: onMotionEvent( MotionEvent event ) ( or onTouchEvent for M5), and onKeyDown( int keyCode, KeyEvent event ) ! An Activity doesn't have those ! So, how can we handle user input, and react accordingly ? If we call intent.startActivity() from within a View , we get an Application Error, with the following description: An error has occurred in process XXX calling startActivity() from outside of an Activity context requires the NEW_TASK_LAUNCH flag. is this really what you want ? The explanation, stating that a flag is required is fine ! But how am I to know the answer to the question ? (is this really what you want ?) http://code.google.com/android/reference/android/content/Intent.html#... If I force the Flag, I will enter into further configuration problems or limitations, due to how we MUST setup the Activity launchMode (http://code.google.com/android/reference/android/ R.attr.html#launchMode) Which means, that I will have several simultaneous tasks for every menu option, which is not what was wanted. I can possibly set my lauchMode to singleTask, but is this really what I want ? I'm just trying to do a simple common thing, react to user input by launching a specific sub activity of the application, like in a menu kind of way. I know that there is the concept of subActivity in M5, that probably helps (not sure though), but this should be easy to do, even in M3 and apparently it's not ! Either I'm missing something, or I haven't still got it, how this is supposed to work. And having Documentation only for M5 stuff, doesn't help much either. Enlightnment on this subject and the View/Activity communcation/user input duality would be real nice. I needed this to work to finish my Contest entry! :( Or else I have to keep using the general Menu, instead of my game Menu, which doesn't quite cut it for a game application. NOTE: I'm trying NOT to break the rest of my app, by Porting the remaining stuff to M5. I have an early version that I had ported to M5, but I went back due to some stuff not working on M5, so not really an option. I also don't expect a new SDK Release now so close to the contest deadline, which could fix a lot of things, but could also bring a whole lot of new bugs too. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: View Parents
thx megat Joshi i´m currently use m5rc15 ,but i solverd the problem. I was triying to assign a static view between 2 activities and when return to main activity show exception. thats occurs because second activity catch the static view an throws the exception when back to main activiy and tries to use that static view. thx again. regards On Apr 3, 8:00 pm, Megha Joshi [EMAIL PROTECTED] wrote: Hi, Please post the following information to debug your issue: 1) SDK version 2) Relevant code 3) logcat output Thanks, Megha On Thu, Apr 3, 2008 at 2:58 PM, [EMAIL PROTECTED] [EMAIL PROTECTED] wrote: when i triying to change from a subactivity to main activity then push navigation keys and appear an exception what does mean? parameter must be a descendant of this view --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.
