Объявите переменную
public static String YOUR_AWESOME_ACTION = "YourAwesomeAction";
, затем добавьте onUpdate и onReceive
@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager,
int[] appWidgetIds) {
ComponentName thisWidget = new ComponentName(context, DigitalClock.class);
RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.digital_clock);
for (int widgetId : appWidgetManager.getAppWidgetIds(thisWidget)) {
remoteViews.setOnClickPendingIntent(R.id.imageView, getPendingSelfIntent(context, YOUR_AWESOME_ACTION));
appWidgetManager.updateAppWidget(thisWidget, remoteViews);
}
}
@Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
super.onReceive(context, intent);
if (YOUR_AWESOME_ACTION.equals(intent.getAction())) {
AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(context);
RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.digital_clock);
ComponentName watchWidget = new ComponentName(context, DigitalClock.class);
appWidgetManager.updateAppWidget(watchWidget, remoteViews);
Intent ntent = new Intent(context, MainActivity.class);
ntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(ntent);
//Toast.makeText(context, YOUR_AWESOME_ACTION, Toast.LENGTH_SHORT).show();
}
}
protected PendingIntent getPendingSelfIntent(Context context, String action) {
Intent intent = new Intent(context, getClass());
intent.setAction(action);
return PendingIntent.getBroadcast(context, 0, intent, 0);
}
и добавьте активность в Manifest
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
надеюсь, это поможет
