I have a homescreenwidget in Android with two buttons. Both buttons should call the same activity ( class ) just use a different intent plus intent extras, to know which button called the class. For now only button1 is working and calling the activity. I also receive the keyvalue in the called Activity.
How can i make the second button work? Here's my code:
public void onUpdate(Context context, AppWidgetManager appWidgetManager,
int[] appWidgetIds) {
super.onUpdate(context, appWidgetManager, appWidgetIds);
for ( int i =0; i<appWidgetIds.length ; i++){
int appWidgetId = appWidgetIds[i];
Intent intent2 = new Intent(context, Main.class);
Intent intent1 = new Intent(context, Main.class);
// Intent put extras Button 1
String bread1 = "secure";
Bundle basket1 = new Bundle();
basket1.putString("key", bread1);
intent1.putExtras(basket1);
// Intent put extras Button 2
String bread2 = "insecure";
Bundle basket2 = new Bundle();
basket2.putString("key", bread2);
intent2.putExtras(basket2);
PendingIntent pending1 = PendingIntent.getActivity(context,0,intent1, 0);
PendingIntent pending2 = PendingIntent.getActivity(context, 0, intent2, 0);
RemoteViews views1 = new RemoteViews(context.getPackageName(),R.layout.maina);
RemoteViews views2 = new RemoteViews(context.getPackageName(),R.layout.maina);
views1.setOnClickPendingIntent(R.id.button1, pending1);
views2.setOnClickPendingIntent(R.id.button2, pending2);
appWidgetManager.updateAppWidget(appWidgetId, views1);
appWidgetManager.updateAppWidget(appWidgetId, views2);
here is the maina.xml
<?xml version="1.0" encoding="utf-8"?>

@Arnold you have created 2 PendingIntent which are....
PendingIntent pending1 = PendingIntent.getActivity(context,0,intent1, 0);
PendingIntent pending2 = PendingIntent.getActivity(context, 0, intent2, 0);
Where PendingIntent.getActivity(Context context, int requestCode, Intent intent, int flags) has 4 parameters. You have to send different "requestCode" for different PendingIntents.
Your code should be....
PendingIntent pending1 = PendingIntent.getActivity(context,0,intent1, PendingIntent.FLAG_UPDATE_CURRENT);
PendingIntent pending2 = PendingIntent.getActivity(context, 1, intent2, PendingIntent.FLAG_UPDATE_CURRENT);
in the main class you need to create this...
String value;
@Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
Bundle b=intent.getExtras();
try{
value=b.getString("key");
}
catch (Exception e) {
// TODO: handle exception
}
super.onReceive(context, intent);
}
with the onUpdate code....
@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager,
int[] appWidgetIds) {
// Get all ids
ComponentName thisWidget = new ComponentName(context,
main.class);
int[] allWidgetIds = appWidgetManager.getAppWidgetIds(thisWidget);
for (int widgetId : allWidgetIds) {
// Create some random data
RemoteViews remoteViews = new RemoteViews(context.getPackageName(),
R.layout.main);
// Register an onClickListener for 1st button
Intent intent = new Intent(context, main.class);
intent.setAction(AppWidgetManager.ACTION_APPWIDGET_UPDATE);
intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS,allWidgetIds);
intent.putExtra("key", "1st Button");
PendingIntent pendingIntent = PendingIntent.getBroadcast(context,
0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
remoteViews.setOnClickPendingIntent(R.id.button1, pendingIntent);
// Register an onClickListener for 2nd button............
Intent intent2 = new Intent(context, main.class);
intent2.setAction(AppWidgetManager.ACTION_APPWIDGET_UPDATE);
intent2.putExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS,allWidgetIds);
intent2.putExtra("key", "2nd Button");
PendingIntent pendingIntent2 = PendingIntent.getBroadcast(context,
1, intent2, PendingIntent.FLAG_UPDATE_CURRENT);
remoteViews.setOnClickPendingIntent(R.id.button2, pendingIntent2);
appWidgetManager.updateAppWidget(widgetId, remoteViews);
}
}
Then you can check whether value=1st Button or value=2nd Button to know which Button has been clicked. It should work... IF it does not work please let me know what is the problem...
I had a similar problem with using 2 buttons on a widget. I set OnClickPendingIntents on both of them, distinguished by different setExtra() calls. But only the latter intent was called, even when clicking the first button. I found 2 solutions: - assign different actions to both PendingIntents - on the second PendingEvent set the PendingEvent.FLAG_CANCEL_CURRENT flag
I am quite unfamiliar with PendingEvents and Widgets, so I can't see the pros and cons and will stick to the first solution.
Maybe that might help you with your problem, too.
Your widget will only have 1 remote view. Try changing the end of your code snippet to:
RemoteViews remoteView = new RemoteViews(context.getPackageName(),R.layout.maina);
remoteView.setOnClickPendingIntent(R.id.button1, pending1);
remoteView.setOnClickPendingIntent(R.id.button2, pending2);
appWidgetManager.updateAppWidget(appWidgetId, remoteView);
Failing that, it would be useful to see your layout in R.layout.maina
