Question

我在stackoverflow上看到很多帖子，但我无法找到解决问题的方法。

我收到了一个自定义内容视图的通知，其中包含一个与RemoteViews链接的按钮。我按照此链接（Adding button action in custom notification）将操作附加到我的按钮，但我的BroadcastReceiver从未被触发。代码：

private void createNotification(int index){
    final int id = index;
    RemoteViews contentView = new RemoteViews(getPackageName(), R.layout.custom_notification);
    contentView.setInt(R.id.container,"setBackgroundColor",ContextCompat.getColor(this,BG_COLORS[index]));
    contentView.setImageViewResource(R.id.logo,BUTTON_OFF[index]);
    contentView.setTextViewText(R.id.sound, getString(SOUND_NAME[index]) );

    NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this)
            .setSmallIcon(R.drawable.ic_launcher)
            .setContent(contentView);

    Intent notificationIntent = new Intent(this, MainActivity.class);
    PendingIntent contentIntent = PendingIntent.getActivity(this, id, notificationIntent, 0);

    Notification notification = mBuilder.build();
    notification.contentIntent = contentIntent;
    notification.flags |= Notification.FLAG_AUTO_CANCEL;

    Intent closeButton = new Intent(this,StopReceiver.class);
    closeButton.setAction(StopReceiver);
    PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, closeButton,0);
    contentView.setOnClickPendingIntent(R.id.stop,pendingIntent);


    mNotificationManager.notify(id, notification);


}

  public static class StopReceiver extends BroadcastReceiver  {

    @Override
    public void onReceive(Context context, Intent intent) {
          //Never called
        Log.d(LOGTAG,"Received Cancelled Event");
        ...
    }
 }

我还在我的AndroidManifest.xml中声明了我的接收器：

<receiver android:name="StopReceiver" android:enabled="true" />

谢谢。

您将RemoteViews的setOnClickPendingIntent设置为通知的自定义RemoteView后设置。

在调用setContent之前尝试设置setOnClickPendingIntent。 E.g：

RemoteViews contentView = new RemoteViews(getPackageName(), R.layout.custom_notification);
contentView.setInt(R.id.container,"setBackgroundColor",ContextCompat.getColor(this,BG_COLORS[index]));
contentView.setImageViewResource(R.id.logo,BUTTON_OFF[index]);
contentView.setTextViewText(R.id.sound, getString(SOUND_NAME[index]) );

Intent closeButton = new Intent(this,StopReceiver.class);
closeButton.setAction(StopReceiver);
PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, closeButton,0);
 contentView.setOnClickPendingIntent(R.id.stop,pendingIntent);

NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this)
    .setSmallIcon(R.drawable.ic_launcher)
    .setContent(contentView);

如果您在小部件中使用列表视图，则在各个项目上设置PendingIntents会非常昂贵，因此是不允许的。而是可以在集合上设置一个PendingIntent模板，您可以使用setOnClickFillInIntent（）

  RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget_article_list_item);
  Intent intent = new Intent(context, ArticleDetailActivity.class);  //activity to start
  intent.putExtra("article",articleList.get(position));//any data to send
   //don't use pending intent here
  views.setOnClickFillInIntent(R.id.widget_item, intent);

您可以在覆盖方法getViewAt(final int position) { ... }中使用它

等待远程视图的意图不起作用
