如何设置通知与播放/暂停，下一首和previous按钮，在Android的！

how to set notification with play/pause, next and previous button in android.!

我是新与Android和放大器;此外，在堆栈溢出。所以，请多多包涵。

I am new with Android & also at stack overflow. So please bear with me.

我设置的通知时，歌曲开始播放象下面这样：

I set notification when song is start to play like below :

`

@SuppressLint("NewApi")
public void setNotification(String songName){
    String ns = Context.NOTIFICATION_SERVICE;
    NotificationManager notificationManager = (NotificationManager) getSystemService(ns);


    @SuppressWarnings("deprecation")
    Notification notification = new Notification(R.drawable.god_img, null, System.currentTimeMillis());

    RemoteViews notificationView = new RemoteViews(getPackageName(), R.layout.notification_mediacontroller);

    //the intent that is started when the notification is clicked (works)
    Intent notificationIntent = new Intent(this, AudioBookListActivity.class);
    PendingIntent pendingNotificationIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);

    notification.contentView = notificationView;
    notification.contentIntent = pendingNotificationIntent;
    notification.flags |= Notification.FLAG_NO_CLEAR;

    //this is the intent that is supposed to be called when the button is clicked
    Intent switchIntent = new Intent(this, AudioPlayerBroadcastReceiver.class);
    PendingIntent pendingSwitchIntent = PendingIntent.getBroadcast(this, 0, switchIntent, 0);

    notificationView.setOnClickPendingIntent(R.id.btn_play_pause_in_notification, pendingSwitchIntent);
    notificationManager.notify(1, notification);        
}

`

我已创建BroadcastReceiver的象下面这样：  `

I have create BroadcastReceiver like below : `

   private class AudioPlayerBroadcastReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();
        System.out.println("intent action = " + action);
        long id = intent.getLongExtra("id", -1);

        if(Constant.PLAY_ALBUM.equals(action)) {
            //playAlbum(id);
        } else if(Constant.QUEUE_ALBUM.equals(action)) {
            //queueAlbum(id);
        } else if(Constant.PLAY_TRACK.equals(action)) {
            //playTrack(id);
        } else if(Constant.QUEUE_TRACK.equals(action)) {
            //queueTrack(id);
        } else if(Constant.PLAY_PAUSE_TRACK.equals(action)) {
 //                playPauseTrack();
            System.out.println("press play");
        } else if(Constant.HIDE_PLAYER.equals(action)) {
 //                hideNotification();
            System.out.println("press next");
        }
        else {
        }
    }

}`

现在，我成功设置自定义通知，但我怎么能处理通知按钮和事件，如播放/暂停，previous和明年......等我也尝试使用广播接收器，但不能得到任何回应。

Now, I set custom notification successfully but how can i handle notification buttons and its events like play/pause, previous and next... etc. I also try using broadcast receiver but could not get any response.

寻求专家的解决方案和指导，请帮助我。

在此先感谢。

推荐答案

您需要设置一个自定义的意图行动，而不是 AudioPlayerBroadcastReceiver 组件类。

You need to set a custom intent action, not the AudioPlayerBroadcastReceiver component class.

像这样的自定义操作的名称创建一个意图

Create a Intent with custom action name like this

  Intent switchIntent = new Intent("com.example.app.ACTION_PLAY");

然后，注册 PendingIntent 广播接收

  PendingIntent pendingSwitchIntent = PendingIntent.getBroadcast(this, 100, switchIntent, 0);

然后，设置一个的onClick 的播放控制，怎么做，如果需要其他控件类似的自定义操作。

Then, set a onClick for the play control , do similar custom action for other controls if required.

  notificationView.setOnClickPendingIntent(R.id.btn_play_pause_in_notification, pendingSwitchIntent);

接下来，注册在 AudioPlayerBroadcastReceiver 自定义操作这样

   <receiver android:name="com.example.app.AudioPlayerBroadcastReceiver" >
        <intent-filter>
            <action android:name="com.example.app.ACTION_PLAY" />
        </intent-filter>
    </receiver>

最后，当比赛被点击通知 RemoteViews 的布局，您将收到玩动作的的BroadcastReceiver

Finally, when play is clicked on Notification RemoteViews layout, you will receive the play action by the BroadcastReceiver

public class AudioPlayerBroadcastReceiver extends BroadcastReceiver{
@Override
public void onReceive(Context context, Intent intent) {

    String action = intent.getAction();

    if(action.equalsIgnoreCase("com.example.app.ACTION_PLAY")){
        // do your stuff to play action;
    }
   }
}

编辑：如何设置意图过滤器在code注册的广播接收器的

您还可以设置自定义操作到意图过滤器从code为注册广播接收器像这样

You can also set the Custom Action through Intent filter from code for the registered Broadcast receiver like this

    // instance of custom broadcast receiver
    CustomReceiver broadcastReceiver = new CustomReceiver();

    IntentFilter intentFilter = new IntentFilter();
    intentFilter.addCategory(Intent.CATEGORY_DEFAULT);
    // set the custom action
    intentFilter.addAction("com.example.app.ACTION_PLAY");
    // register the receiver
    registerReceiver(broadcastReceiver, intentFilter);
