Question

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);
}

然而，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）;

Answer 1

我收到了这个错误：

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设置唯一的requestCode ，为此我使用提供的 appWidgetId 而不是仅使用 0 < / strong>每次。

getBroadCast（）


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

getActivity（）


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

由于某些未知原因，它在文档中说“目前没有使用”？


requestCode 发件人的私人请求代码（当前未使用）。

但它有效;）

Answer 2

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

Answer 3

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