[android-beginners] What is a toast?
Hi, Could somebody give me some detailed information about toast? I got a comment saying that This is called a toast and cannot be dismissed by the user. Toasts are dismissed automatically after a fixed period of time. Then why the period of time for a toast is more, which degrades the user experience.

Re: [android-beginners] What is a toast?
Think of Toast like a subtitle in movies. It's a simple text that shows for X seconds. It has no buttons, it's like a bubble that tells you something happened, then vanishes out. If you setup a long period for a toast, that will be visible too long and will degrade the user experience, as in movies if you have a subtitle on screen for a long time, longer then the speech, you dislike it. http://www.androidx.org/wp-content/uploads/2009/10/android-toast-usage-03.png 2009/11/10 pushkar bandi pushkarse...@gmail.com Hi, Could somebody give me some detailed information about toast?

Re: [android-beginners] What is a toast?
From the dev guide (http://developer.android.com/reference/android/widget/Toast.html): A toast is a view containing a quick little message for the user. The toast class helps you create and show those. When the view is shown to the user, appears as a floating view over the application. It will never receive focus. The user will probably be in the middle of typing something else. The idea is to be as unobtrusive as possible, while still showing the user the information you want them to see. Two examples are the volume control, and the brief message saying that your settings have been saved. Think of it like the transient notification pop-ups you get in Pidgin or MSN messenger. It appears for a pre-determined amount of time, at a position specified by the developer. It differs from a pop-up dialog because you can continue to interact with the UI whilst it is being displayed, and you are not expected to act on it. The period of time for a toast is customisable, you want to use the setDuration() method to change it: http://developer.android.com/reference/android/widget/Toast.html#setDuration(int).

[android-beginners] Help with creating a sport scoring application
Hi community I am new to programming...i have this idea of creating a sport scoring app but i have no idea how to do the coding i knw some basic concepts of object oriented programming but i want to knw how to layout the structure of the programming if anyone wants to join me (can share the rights) or help me out in this project you will be most welcome i have a solid business plan for this app... the basic idea of the app is as follows in any sportat any given event has finite set of outcomes so the interface is an intuitive interface to score and keep statistics... usually sport scoring applications are very very clumsy with all the options on one screen in this...v start from idle postion ...lets say in cricket t idle position is the bowler bowling the ball once the bowler bowls ...there are finite outcomes ...the screen shows only those options required at THAT point of time...the next screens depend on the option u chooseif you choose out...the next screen will ask u how he was out if its a run...then next options wil be how many ...next will be wich area...n so on i believe the app needs strong database and data counters its all confusing for me but i am very clear abt the requirements for the app plz contact me if any one is interested -- You received this message because you are subscribed to the Google Groups Android Beginners group.

[android-beginners] changing a package name
Hello This is more a Java question than Android I have a graphing routine AChartEngine (very very good by the way). Now I want to link this with another routine say a sound recording activity. They are in different packages and different projects. AChartEngine has lots of Lib's and Referenced Libraries, so it's easier to move the other stuff there. However the charting demo has the demo package name and the demo project name. What is the best way to move these things about? Is there a sensible text which explains more about packages and libraries etc? Thanks John -- You received this message because you are subscribed to the Google Groups Android Beginners group.

That's interesting. I've never run into that problem before. It probably has something to do with what classes you are in or something like that. Here's a question... did you try the Toast in the same place where using AlertDialog.Builder gives an error or were they in different parts of your code?

Re: [android-beginners] Re: how to call a function after taking snap from camera?? plz help
hi Chris !! Its after a long time i am responding to your suggestion
:S. I was out of this task for a while. I tried your suggestion that
to use StartActivityForResult and then calling mufunction() in an
override of onActivityResult(). But its not working and being a newbie
its tough to find the cause very quickly.
I tried like this ..
Intent intent = new Intent();
intent.setClassName(com.android.camera,
com.android.camera.Camera);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
//startActivity(intent);
startActivityForResult(intent,0);
@Override
protected void onActivityResult(int requestCode, int
resultCode,Intent data)
{
super.onActivityResult(requestCode, resultCode, data);
decode(); //function which i want to call
}
I searched for few examples using onActivityResult() and i found that
it used requestCode with Switch in most of them. I am confused what to
pass with Intent(intentobject, ?) and what would i receive in
requestCode variable ??
Remember i intend to take a snap from camera app and want to execute
decode() function.
Kindly help.

Hi Ev1 !!

Rite now the camera app is successfully opened but after taking one snap the camera app doesnt quits :S.

But i am not clear how to use it. what to pass along with Intent(Intentobject, ?) what to receive in RequestCode variable in override version of onActivityResult(). Hope i made myself clear.

[android-beginners] Re: getApplicationContext() AlertDialog.Builder
I tried
b.create().show();
but that did not solve the problem. This is very strange. If I can use
'getApplicationContext()' and 'this' interchangeably when dealing with
Toast messages, I assume that those two are in fact pretty much the
same. Now, on the other hand, when dealing with that
AlertDialog.Builder class, where I can use 'this', but using
'getApplicationContext()' results in a runtime error when showing the
dialog, I must assume that 'this' and 'getApplicationContext()' are
NOT the same. How is that possible?
Anyway, here is a error log. Maybe someone can think of a solution
while looking at the actual error message.
...
WARN/WindowManager(56): Attempted to add window with non-application
token WindowToken{43be4580 token=null}. Aborting.

Oh, and thank you Justin for your effort! I really appreciate your
help!

Toast.makeText(getApplicationContext(), Hello World!,
Toast.LENGTH_SHORT).show();
AlertDialog.Builder b = new AlertDialog.Builder(getApplicationContext

[Dialog configuration]
b.show();
While the Toast message gets displayed right away, the AlertDialog
won't. Instead there is a runtime error. Like I said, if you replace
the getApplicationContext() with this, it works flawlessly.

That's interesting. I've never run into that problem before. It

has something to do with what classes you are in or something like
that.
Here's a question... did you try the Toast in the same place where
using
AlertDialog.Builder gives an error or were they in different parts of
your
code?
Thanks,
Justin

Hi everybody,
can somebody please explain why
AlertDialog.Builder b = new
AlertDialog.Builder(getApplicationContext

will result in a runtime error, while
AlertDialog.Builder b = new AlertDialog.Builder(this);
will run just fine? I can use this and getApplicationContext()
with Toast.makeText() interchangeably without any problems. What is
different with that AlertDialog.Builder? Any ideas?
Cheers, Matt

[android-beginners] Re: Unable to select build target for new Android project
Figured it out. I use a netbook. The resolution was set so that it squished the box. I fixed it by changing the screen orientation. Good luck!

[android-beginners] Problem in GPS while running in timer
Hi frinds..
I am presently working on GPS.I have to start GPS periodically.I mean
I want GPS to start after a particular intervel,get Location value and
then stop taking location updates.For this,I m calling
requestLocationUpdates( , , ) method in a timer.Then in
onLocationChanged(), I stop taking location by using removeUpdates
().Then after particular intervel ,it again start taking values,then
when location changes ,it stops, and so on..
Here is my code:
TimerTask IntervelTimer = new TimerTask()
{
public void run()
{
Log.d
(startLocationUpdate,startLocationUpdate);
startLocationUpdate();
}
};
Timer timer2 = new Timer();
try{
timer2.schedule(IntervelTimer, 1*60 * 1000, 1*60 * 1000);
}
catch(Exception e)
{
Log.e(Error,e.toString());
}
public void startLocationUpdate()
{
System.out.println(startLocationUpdate());
if(locationListener==null)
{
Looper.prepare();
locationListener = new MyLocationListener();
try{
lm.requestLocationUpdates(
LocationManager.GPS_PROVIDER,
0,
0,
locationListener);
}
catch(Exception e)
{
Log.e(error,e.toString());
}
Looper.loop();
Looper.myLooper().quit();
}
}
private class MyLocationListener implements LocationListener
{
public void onLocationChanged(Location loc) {
System.out.println(GetLocation);
if (loc != null) {
StoreGPSlocation(String.valueOf
(loc.getLatitude()),String.valueOf(loc.getLongitude()));
stopLocationUpdate();
}
}
public void onProviderDisabled(String provider) {
// TODO Auto-generated method stub
}
public void onProviderEnabled(String provider) {
// TODO Auto-generated method stub
}
public void onStatusChanged(String provider, int status,
Bundle extras) {
// TODO Auto-generated method stub
}
}
public void stopLocationUpdate()
{
LocationManager lm = (LocationManager)getSystemService
(Context.LOCATION_SERVICE);
if (lm != null)
{
if (locationListener != null)
{
lm.removeUpdates(locationListener);
locationListener= null;
}
lm = null;
}
}
Now the problem is:It starts fine for the first time,when location
changes it stops then starts again,but the timer stops running after
that.I dont get any error or exception.I dont know where is the
problem.As far as I am concirned,the problem is in timer..
What do you guys think...
I need Help. urgently!!!
Thanks in Advance
Nemat

[android-beginners] Buttons within custom dialog?
I am trying to get a custom dialog to have buttons that manipulate the
progress of a seekbar. I've set up the dialog layout through xml but I
can't get the buttons to work.
This is the code I'm getting stuck on:
protected Dialog onCreateDialog(int id) {
Dialog WoundSlider = new Dialog(this);
Button BDOWN = (Button) WoundSlider.findViewById(R.id.BDOWN);
BDOWN.setOnClickListener(new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
}
});
I keep getting an error that says: The method setOnClickListener
(View.OnClickListener) in the type View is not applicable for the
arguments (new DialogInterface.OnClickListener(){})
It then lists several other listeners that it suggest I change to but
I get the same error for all of them. How do I set up a listener
within a custom dialog?
