在远程视图中设置视图的可见性不起作用

Question

我正在尝试更改通知中 imagviews 的可见性，当其中一个单击并且即使接收器上的单击触发器已调用，也没有任何反应。

我的接收代码 ：

public class NotificationInteractionReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
    if (context instanceof ExoPlayerService){
        ExoPlayerService service= (ExoPlayerService) context;
        RemoteViews views=NotificationHelper.remoteViews;
        if (views==null){
            return;
        }
        if (intent.getAction().equals(NotificationHelper.NOTIFY_DELETE)){
            Log.e("NotificationReceiver","delete button clicked");
        }
        if (intent.getAction().equals(NotificationHelper.NOTIFY_NEXT)){
            Log.e("NotificationReceiver","next button clicked");
        }
        if (intent.getAction().equals(NotificationHelper.NOTIFY_PREVIOUS)){
            Log.e("NotificationReceiver","previous button clicked");
        }
        if (intent.getAction().equals(NotificationHelper.NOTIFY_PAUSE)){
            Log.e("NotificationReceiver","pause button clicked");
            views.setViewVisibility(R.id.pauseBtn_notification, View.GONE);
            views.setViewVisibility(R.id.playBtn_notification, View.VISIBLE);
        }
        if (intent.getAction().equals(NotificationHelper.NOTIFY_PLAY)){
            Log.e("NotificationReceiver","play button clicked");
            views.setViewVisibility(R.id.playBtn_notification,View.GONE);
            views.setViewVisibility(R.id.pauseBtn_notification, View.VISIBLE);
        }
    }
}

}

代码块末尾缺少更新。您需要输入如下代码：

ComponentName thisWidget = new ComponentName(context, MainWidget.class);
AppWidgetManager.getInstance(context).updateAppWidget(thisWidget, remoteViews);
