桌面小部件旋转屏后失效问题
ppWidgetProvider@Overridepublic void onReceive(Context context, Intent intent) { super.onReceive(context, intent); if(intent.getAction().equals("test.CLICK")) { CallTestMethod(context); }}@Overridepublic void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) { final int N = appWidgetIds.length; // Perform this loop procedure for each App Widget that belongs to this provider for (int i=0; i<N; i++) { int appWidgetId = appWidgetIds[i]; RemoteViews views=new RemoteViews(context.getPackageName(), R.layout.widget); Intent clickintent=new Intent("test.CLICK"); PendingIntent pendingIntentClick=PendingIntent.getBroadcast(context, 0, clickintent, PendingIntent.FLAG_UPDATE_CURRENT); views.setOnClickPendingIntent(R.id.change_mode, pendingIntentClick); SetInitialLayout(context); appWidgetManager.updateAppWidget(appWidgetId, views); } super.onUpdate(context, appWidgetManager, appWidgetIds);}?上述代码在旋转屏后失效，解决办法是
@Overridepublic void onReceive(Context context, Intent intent) ? ?{? ? super.onReceive(context, intent);? ? if(intent.getAction().equals("test.CLICK"))? ? {? ? ? ? getIntent().putExtra("Just received click", true);? ? ? ? CallTestMethod(context);? ? }}或者呢 如下使用
@Override?public void onUpdate(Context context, AppWidgetManager appWidgetManager,? ?int[] appWidgetIds) {? context.startService(new Intent(context, MyUpdateService.class));?}public static class MyUpdateService extends Service ?{ ? @Override? public void onCreate() {? ?super.onCreate();? }? @Override? public void onDestroy() {? ?super.onDestroy();? }? @Override ? public void onStart(Intent intent, int startId) ? { ? ?super.onStart(intent, startId); ? ?// Update the widget ? ?RemoteViews remoteView = buildRemoteView(this); ? ?// Push update to homescreen ? ?pushUpdate(remoteView); ? ? ? ? ? ? ?} ? public RemoteViews buildRemoteView(Context context) ? { ? ?int layoutID = R.layout.widget;? ?if (this.getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE){? ? layoutID = R.layout.widget_landscape;? ?}? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? //Here is where you set your onclick listeners again since the remote views need to be refreshed/recreated? ?RemoteViews updateView = new RemoteViews(context.getPackageName(),layoutID); ? ?// Create an Intent to launch ExampleActivity? ?Intent intent = new Intent(this, yourAndroidActivity.class);? ?PendingIntent pendingIntent = PendingIntent.getActivity(this, 0,? ? ?intent, 0);? ?updateView.setOnClickPendingIntent(R.id.yourClickableViewHere, pendingIntent);? ?return updateView; ? } ? @Override ? public void onConfigurationChanged(Configuration newConfig) ? { ? ?RemoteViews remoteView = buildRemoteView(this); ? ? // Push update to home screen ? ?pushUpdate(remoteView); ? } ? private void pushUpdate(RemoteViews updateViews) ? { ? ?ComponentName myWidget = new ComponentName(this, YourAppWidgetbackground-color: transparent; margin: 0px; color: #000000; font-size: 14px; vertical-align: bas
