我想使用以下代码从我的小部件发送广播：

for (int i = 0; i < N; i++) {
   int appWidgetId = appWidgetIds[i];
   RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget);
   Intent x = new Intent();
   if (isActive == true) {
      views.setImageViewResource(R.id.w_image, R.drawable.w_bild);
      x.setAction("de.bulling.smstalk.DISABLE");
   } else {
      views.setImageViewResource(R.id.w_image, R.drawable.w_bild_off);
      x.setAction("de.bulling.smstalk.ENABLE");
   }
   PendingIntent z = PendingIntent.getBroadcast(context, 0, x, PendingIntent.FLAG_ONE_SHOT);
   views.setOnClickPendingIntent(R.id.w_image, z);
   appWidgetManager.updateAppWidget(appWidgetId, views);
}

但是，我收到此错误：

E/RemoteViews(18176): Cannot send pending intent: 
E/RemoteViews(18176): android.content.IntentSender$SendIntentException

这是什么原因？你有什么主意吗？谢谢，马克

/edit：我找到了答案：它必须是 Intent x = new Intent(context, WidgetClass.class);

我得到这个错误：

RemoteViews: Cannot send pending intent:  
RemoteViews: android.content.IntentSender$SendIntentException 
RemoteViews: at android.app.ContextImpl.startIntentSender()

解决方案是为每个（发送）PendingIntent 设置一个唯一的 requestCode，为此我使用提供的appWidgetId而不是每次都使用0 。

获得广播（）

pendingActionIntent=PendingIntent.getBroadcast(this, widgetId , intentAction, pendingFlag);

获取活动（）

pendingActionIntent=PendingIntent.getActivity(this, widgetId , intentAction, pendingFlag);

出于某种未知原因，它在文档中说“当前未使用”？

requestCode 发件人的私人请求代码（当前未使用）。

但它有效；）

我认为请求代码用于通过PendingIntent.FLAG_CANCEL_CURRENT和匹配更新和替换PendingIntent.FLAG_UPDATE_CURRENT。
