我工作的一个音乐播放器，小部件（主屏幕小部件）.. 它只需要打1首歌曲，（preferably用的MediaPlayer类）。但我不知道如何实现它。我有点缺乏经验与Android的发展，只是所以这提到的。

类我到目前为止延伸 AppWidgetProvider ，我想这不是一个好主意，让这个类处理音乐播放部分，而是一个服务。如果是的话，怎么办？

此外，我有3个按钮：播放，暂停，停止，我可以分辨哪一个已经pssed在的onReceive $ P $（...）

在此先感谢！

下面是类。

解决方案

新增＆LT;服务机器人：名称=机器人MusicService。：启用=真/＆GT; 到清单！

I'm working on a music player-widget (home screen widget).. It only needs to play 1 song, (Preferably with the MediaPlayer class). But I'm not sure how to implement it. I'm kind of inexperienced with Android development, just so that's mentioned.

The class I have so far extends AppWidgetProvider, and I guess it is not a good idea to let this class handle the music-playing part, but rather a Service. And if so, how?

Furthermore, I have 3 buttons: play, pause and stop, and I can distinguish which one has been pressed in onReceive(...).

Thanks in advance!

Here is the class.

public class MusicManager extends AppWidgetProvider {

    private final String ACTION_WIDGET_PLAY = "PlaySong";
    private final String ACTION_WIDGET_PAUSE = "PauseSong";
    private final String ACTION_WIDGET_STOP = "StopSong";   
    private final int INTENT_FLAGS = 0;
    private final int REQUEST_CODE = 0;

    @Override
    public void onUpdate(Context context, AppWidgetManager appWidgetManager,
            int[] appWidgetIds) {

        RemoteViews controlButtons = new RemoteViews(context.getPackageName(),
                R.layout.main);

        Intent playIntent = new Intent(context, MusicService.class);

        Intent pauseIntent = new Intent(context, MusicService.class);

        Intent stopIntent = new Intent(context, MusicService.class);


        PendingIntent playPendingIntent = PendingIntent.getService(
                context, REQUEST_CODE, playIntent, INTENT_FLAGS);
        PendingIntent pausePendingIntent = PendingIntent.getService(
                context, REQUEST_CODE, pauseIntent, INTENT_FLAGS);
        PendingIntent stopPendingIntent = PendingIntent.getService(
                context, REQUEST_CODE, stopIntent, INTENT_FLAGS);

        controlButtons.setOnClickPendingIntent(
                R.id.btnPlay, playPendingIntent);
        controlButtons.setOnClickPendingIntent(
                R.id.btnPause, pausePendingIntent);
        controlButtons.setOnClickPendingIntent(
                R.id.btnStop, stopPendingIntent);

        appWidgetManager.updateAppWidget(appWidgetIds, controlButtons);         
    }
}

Added <service android:name=".MusicService" android:enabled="true" /> to the manifest!
