Question

我有一个包含2个待处理意图的AppWidget。他们大部分时间都在工作，但过了一段时间他们就停止了回应。我唯一能够确定的是，在Launcher重新启动后它们会被瘫痪，即我使用Launcher Pro，有时会调整设置并且必须重新启动它。之后他们根本不工作。

以下是我的onRecieve()和onUpdate()方法：

   public void onReceive(Context context, Intent intent)
{
    super.onReceive(context, intent);
    String action = intent.getAction();
    if(action.equals("android.tristan.widget.digiclock.CLICK"))
    {
        PackageManager packageManager = context.getPackageManager();
        Intent alarmClockIntent = new Intent(Intent.ACTION_MAIN).addCategory(Intent.CATEGORY_LAUNCHER);

        String clockImpls[][] = {
                {"HTC Alarm Clock", "com.htc.android.worldclock", "com.htc.android.worldclock.AlarmClock" },
                {"Standar Alarm Clock", "com.android.deskclock", "com.android.deskclock.AlarmClock"},
                {"Froyo Nexus Alarm Clock", "com.google.android.deskclock", "com.android.deskclock.DeskClock"},
                {"Moto Blur Alarm Clock", "com.motorola.blur.alarmclock",  "com.motorola.blur.alarmclock.AlarmClock"}
        };

        boolean foundClockImpl = false;

        for(int i=0; i<clockImpls.length; i++) {
            String vendor = clockImpls[i][0];
            String packageName = clockImpls[i][1];
            String className = clockImpls[i][2];
            try {
                ComponentName cn = new ComponentName(packageName, className);
                ActivityInfo aInfo = packageManager.getActivityInfo(cn, PackageManager.GET_META_DATA);
                alarmClockIntent.setComponent(cn);
                foundClockImpl = true;
            } catch (NameNotFoundException e) {
                Log.d(LOGTAG, "Error," + vendor + " does not exist");
            }
        }

        if (foundClockImpl) {
        Vibrator vibrator = (Vibrator) context.getSystemService(Context.VIBRATOR_SERVICE);
        vibrator.vibrate(50);
        final RemoteViews views = new RemoteViews(context.getPackageName(), layoutID);
        views.setOnClickPendingIntent(R.id.TopRow, PendingIntent.getActivity(context, 0, new Intent(context, DigiClock.class).setFlags(Intent.FLAG_ACTIVITY_NEW_TASK), PendingIntent.FLAG_UPDATE_CURRENT));
        AppWidgetManager.getInstance(context).updateAppWidget(intent.getIntArrayExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS), views);
        alarmClockIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        context.startActivity(alarmClockIntent);       
   }
    }
}

        public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
super.onUpdate(context, appWidgetManager, appWidgetIds);
    context.startService(new Intent(UpdateService.ACTION_UPDATE));
    context.startService(new Intent(context, ScreenUpdateService.class));
    final int Top = appWidgetIds.length;
    final int Bottom = appWidgetIds.length;
    for (int i=0; i<Top; i++)
    {
    int[] appWidgetId = appWidgetIds;
    final RemoteViews top=new RemoteViews(context.getPackageName(), layoutID);
    Intent clickintent=new Intent("android.tristan.widget.digiclock.CLICK");
    PendingIntent pendingIntentClick=PendingIntent.getBroadcast(context, 0, clickintent, 0);
    top.setOnClickPendingIntent(R.id.TopRow, pendingIntentClick);
    appWidgetManager.updateAppWidget(appWidgetId, top);
}
for (int i=0; i<Bottom; i++)
{
    int[] appWidgetId = appWidgetIds;
    RemoteViews bottom=new RemoteViews(context.getPackageName(), layoutID);
    Intent clickintent=new Intent("android.tristan.widget.digiclock.CLICK_2");
    PendingIntent pendingIntentClick=PendingIntent.getBroadcast(context, 0, clickintent, 0);
    bottom.setOnClickPendingIntent(R.id.BottomRow, pendingIntentClick);
    appWidgetManager.updateAppWidget(appWidgetId, bottom);
}
}

我已经读过关于将意图放在服务中，但已经尝试过但失败了。任何帮助表示赞赏。

Answer 1

正如我写的here，您应该只生成一个RemoteView实例。

Answer 2

PendingIntent.getBroadcast有一个名为requestCode的参数，如果有多个PendingIntent，它必须是唯一的代码。您已将所有PendingIntents的值都设置为0。

启动Launcher后，AppWidget PendingIntent无法正常工作
