我正在使用parse.com发送推送通知.它工作正常.

我想通过parse.com发送这个json数据:

{"channel":"game","data":{ "alert":"Red Sox win 7-0!"}}

这是我的主要动力:

    @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    ParseAnalytics.trackAppOpened(getIntent());

    // inform the Parse Cloud that it is ready for notifications
    PushService.setDefaultPushCallback(this, MainActivity.class);
    ParseInstallation.getCurrentInstallation().saveInBackground();

}

1-如何获取此json数据？

2-我发送了json数据,如何禁用通知？当应用程序获得json时,会显示通知并说"解析推送通知".如果我发送json数据,如何禁用此通知？

我有一个奇怪的错误。

我收到了一个带有 3 个按钮（后退、下一步、播放/暂停）的通知。我想在启动服务的这三个按钮中的每一个上设置不同的 pendingIntent。这是我的代码：

    Intent playPauseIntent = new Intent(MyApp.mainActivity, NotificationService.class);
    playPauseIntent.putExtra("do_action", "play");
    contentView.setOnClickPendingIntent(R.id.notifPlayPauseImageView, PendingIntent.getService(MyApp.mainActivity, 0, playPauseIntent, PendingIntent.FLAG_UPDATE_CURRENT));            

    Intent nextRadioIntent = new Intent(MyApp.mainActivity, NotificationService.class);
    nextRadioIntent.putExtra("do_action", "next");
    contentView.setOnClickPendingIntent(R.id.notifNextImageView, PendingIntent.getService(MyApp.mainActivity, 0, nextRadioIntent, PendingIntent.FLAG_UPDATE_CURRENT));

    Intent previousRadioIntent = new Intent(MyApp.mainActivity, NotificationService.class);
    previousRadioIntent.putExtra("do_action", "previous");
    contentView.setOnClickPendingIntent(R.id.notifPreviousImageView, PendingIntent.getService(MyApp.mainActivity, 0, previousRadioIntent, PendingIntent.FLAG_UPDATE_CURRENT));

    notification.contentView = contentView;
    mNotificationManager.notify(1, notification); 

然后，在我的服务中，我将“do_action”的意图和值定义为额外的：

@Override
public int onStartCommand(Intent intent,  int flags, int startId) { 

   if(intent != null && intent.getExtras() != null)
   {
      String action = (String) intent.getExtras().get("do_action"); // BUG HERE ! I always get …

ImageViewpushIcon占据了位置但不可见，知道为什么吗？

我正在创建这样的通知。

Notification.Builder builder = new Notification.Builder(context);
        builder.setContentTitle(notifyMessage1)
                .setContentText(notifyMessage2)
                .setSmallIcon(R.mipmap.ic_launcher);

Notification notification = builder.build();

我想在我的通知中添加一个操作

builder.addAction();

实现addAction(icon, title, pendingIntent);已弃用

我的目标是创建一个没有图标的通知操作，我该如何实现？
