I have been using a hand built ListActivity as my AppWidget config Activity but to be honest it looks ****ty and doesnt fit in with the rest of the app. So i wanted to transition over to a PreferenceActivity. i made a stub of a PreferenceActivity that launches the layout just fine when it is the main activity. but when i try to change from my ListActivity to my PreferenceAcitivity i get no launching of PreferenceActivity when i launch my widget. all i get is my widget.
i did a refactoring of my xml files to change the instances of my ListActivity (GITextConfig) to my PreferenceActivity (GITextPreferences).
how can i use a PreferenceActivity as my config?
do i need to have a dummy Activity be the config with a button to launch the PreferenceActivity? cause that works just fine. its lame and shouldnt be that way... nvm that does not work... i just cant get a prefs activity to run from an appwidget
anyone? this is quite annoying... i know it can be done as other widgets like gmail unread count does this. at least it appears to have a preferenceactivity as the configuration
got it to work. i dont know what i was doing before but i think i had a little too much of a stub for it to work. after i implemented the appwidget id verification and created my PreferenceManger and overode the onBackPressed() method it seems to work.... happy and confused.
Code:
public class GITextPreferences extends PreferenceActivity {
private int mAppWidgetId = AppWidgetManager.INVALID_APPWIDGET_ID;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
PreferenceManager localPrefs = getPreferenceManager();
localPrefs.setSharedPreferencesName("GITC_Prefs");
addPreferencesFromResource(R.xml.gitc_preferences);
// Find the widget id from the intent.
Intent intent = getIntent();
Bundle extras = intent.getExtras();
if (extras != null) {
mAppWidgetId = extras.getInt(AppWidgetManager.EXTRA_APPWIDGET_ID, AppWidgetManager.INVALID_APPWIDGET_ID);
}
// If they gave us an intent without the widget id, just bail.
if (mAppWidgetId == AppWidgetManager.INVALID_APPWIDGET_ID) {
finish();
}
}
@Override
public void onBackPressed() {
// Make sure we pass back the original appWidgetId
Intent resultValue = new Intent();
resultValue.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, mAppWidgetId);
setResult(RESULT_OK, resultValue);
finish();
}
}
Hello app developers!
I have got serious problem. Every time I call alertdialogs or other dialogs I see them only in activity. But my app needs to show this dialog when user works on phone, that's why it must be shown out of activity. Any ideas?

You cannot do this. There is simply no feature for that. I have had that problem, too.
Use a Notification or a Toast message.
There is a work-around for this. If you run a service, you can technically launch an activity that can resemble this.
I have an app that uses a broadcast receiver to listen for the events I want to alert my user to. I created a custom layout for my alert dialog and then when the event happens, my broadcast receiver calls the activity.

Yes, great idea. Launch a transparent Activity and start a dialog. Set an onDismissListener and close the app when the dialog is closed.

If I start a transparent activity user can't see that it was started as I understand. Can you give code for broadcast receiver maybe I misunderstand something
The broadcast receiver is just the mechanism I use to launch the activity. It is a mere intent that I start from it. Below is the class I use for my alertdialog. You won't be able to cut and paste because I also created my own class to dismiss the activity.
Code:
public class SilentDialog extends TimedActivity implements OnTouchListener{
Intent intent;
[user=439709]@override[/user]

this.requestWindowFeature(Window.FEATURE_NO_TITLE);
//Remove notification bar
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
super.onCreate(savedInstanceState);
showAlert();
}
[user=439709]@override[/user]

//this is very important here ;)
super.onDestroy();
}
public boolean onTouch(View v, MotionEvent event)
{

//reset idle timer
// put this here so that the touching of empty space is captured too
// it seems that LinearLayout doesn't trigger a MotionEvent.ACTION_UP or MotionEvent.ACTION_MOVE

I understood everything except the way how app switch between position before signal came and required activity with alert dialog in it. As I see this code initialize activity and alert dialog but don't contain switching that I need
Are you asking how I call the dialog? If so, a simple intent from a broadcast receiver.
Code:
Intent i = new Intent(context, SilentDialog.class);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(i);
I would use the AlertDialog.Builder class for compatibility.
Why not use a notification, I think that is more elegant.
Code:
public class InstalledReceiver extends BroadcastReceiver {
private NotificationManager mNotificationManager ;
[user=439709]@override[/user]
public void onReceive(Context context, Intent intent) {
if (BaseActivity.DEBUG) System.out.println("Received Broadcast");
Boolean update = intent.getBooleanExtra(Intent.EXTRA_REPLACING, false);
mNotificationManager = (NotificationManager) context.getSystemService("notification");
SharedPreferences getPrefs = PreferenceManager.getDefaultSharedPreferences(context);
Boolean disabledNotifications = getPrefs.getBoolean("disableNotifications", false);
if (!disabledNotifications && !update) makeNotification(context);
}
private void makeNotification(Context context) {
CharSequence label = context.getString(R.string.labelNotify);
CharSequence text = context.getString(R.string.textNotify);
CharSequence full = context.getString(R.string.fullNotify);
final Notification notification = new Notification(R.drawable.ic_launcher,text,System.currentTimeMillis());
notification.setLatestEventInfo(context,label,full,null);
notification.defaults = Notification.DEFAULT_ALL;
mNotificationManager.notify( 0, notification);
}
}

I agree, but if he wants to use a dialog, we help him to make one.
The bad thing about the dialog is that it will interrupt whatever the user is doing. This could be very annoying. And who wants to use an app which has annoying popups?

When I use this code activity don't shows when I am out of application. For example Handcent SMS when SMS comes to user shows up a great dialog over all windows. My aim is the same thing

Start an Activity. Set a transparent layout. Show a dialog. That will result in what you want.

Intent intent=new Intent();
intent.setAction("Navi_Beep");
sendBroadcast(intent);
r.play();

Ah. You need to call setContentView. Create a transparent View and pass it as a parameter.

Doesn't help:

public void onCreate(Bundle savedInstanceState) {
Log.d("NaviBeep","Here");
View view=new View(this);
view.setBackgroundColor(Color.TRANSPARENT);

intent.setAction("Navi_BeepOff");
sendBroadcast(intent);
finish();
}
});
// Set the Icon for the Dialog

}
}
If you use another layout, is the Activity opened?
Is the "Here" written to the log? Is there any Error message?
And I recommend configuring the AlertDialog within the AlertDialog.Builder: http://www.mkyong.com/android/android-alert-dialog-example/
(However, I guess that it will not solve your problem.)

});
alertDialog.setCancelable(false);
dialog = alertDialog;//new AlertDialog.Builder(this).setMessage("ERROR! This is a global dialog\n Brought to you by Sherif").create();

Hello! I'm new to this forum. I'm developing an Android app, I have some problems with the functionality of a timer and I don't figure out why. I would need some ideas.
In my application I have 2 activities: one is with the levels of a game, where you can chose between them and the second one is with the game itself. In the second activity I have a CountDownTimer which tells me when the game must finish. I have a progressBar assigned to that timer.
CountDownTimer mCountDownTimer; -global variable
In onCreate I have:
mProgressBar=(ProgressBar)findViewById(R.id.progressBar);
mProgressBar.setProgress(0);
mCountDownTimer=new CountDownTimer(90000,1000) {
int i=0;
@override
public void onTick(long millisUntilFinished) {
Log.v("Log_tag", "Tick of Progress" + i + millisUntilFinished);
i++;
mProgressBar.setProgress(i); }
@override
public void onFinish() {
i++;
mProgressBar.setProgress(i);
Intent in = new Intent(getApplicationContext(), MyActivity2.class);
startActivity(in);
}
};
mCountDownTimer.start();
I have also overriden the native back button from Android to go to the first activity, the one with the levels and there I try to stop the counter, but it doesn't seem to work at all. The counter doesn't stop, and the other functions don't work as well.
Here is the code:
public boolean onKeyDown(int keyCode, KeyEvent event) {
if ((keyCode == KeyEvent.KEYCODE_BACK)) { //Back key pressed
mCountDownTimer.cancel();
Intent in = new Intent(getApplicationContext(), MyActivity2.class);
startActivity(in);
mCountDownTimer.cancel();
return true;
}
return super.onKeyDown(keyCode, event);
}
public void onBackPressed(){
mCountDownTimer.cancel();
Intent in = new Intent(getApplicationContext(), MyActivity2.class);
startActivity(in);
return;
How could I solve this? Thank you so much!
Here is your problem:
CountDownTimer mCountDownTimer; -global variable
There are no global variables in Java, only instance variables. Since you didn't post your full code I'm going to make a few assumptions here...
public class myAwesomeTimerClass {
CountDownTimer mCountDownTimer;
// bla bla
}
Then in your second activity/class, you should refer to the class:
instead of:
mCountDownTimer.cancel();
try:
myAwesomeTimerClass.mCountDownTimer.cancel();
Good luck.
Hi Im just starting to learn android code and I dont understand why this doesnt work. Just for as a test I wanted to create 2 pages (or 1 page and 1 popup page but i thought 2 pages would be easier to make), and a way to get from one to the other, which I thought could be solved easly with a button on each page which takes me to the other page.
So I started with this:
HTML:
final ImageButton button = (ImageButton) findViewById(R.id.imageButton);
button.setOnClickListener(new View.OnClickListener() {
[user=439709]@override[/user]
public void onClick(View v) {
setContentView(R.layout.layout2);
} });
Basicually I start in a layout called activity_my which has a button and when I press it I get to the next page called layout2. I thought I could just make a similiar function to get back to my original page:
HTML:
final Button button2 = (Button) findViewById(R.id.button);
button2.setOnClickListener(new View.OnClickListener() {
[user=439709]@override[/user]
public void onClick(View v) {
setContentView(R.layout.activity_my);
}
});
But now I get error for whatever reason
Hi,
Basically in android, a 'page' is an Activity (class where you attach a XML layout).
So you must create 2 activity with 2 layout.
To switch activity use this foloowing code :
HTML:
Intent intent = new Intent(this, YourSecondActivity.class);
startActivity(intent);
