java – 如何停止MediaPlayer流然后重新启动它？ Android的

我正在制作一个简单的应用程序来播放在线广播流.我知道如何设置流.到目前为止,这是我的代码.它设置流并播放它.但如果我停下来,我就无法重新开始.我错过了一些明显的东西吗

final MediaPlayer mediaPlayer = new MediaPlayer();
    mediaPlayer.setAudioStreamType(Au@L_284_2@manager.STREAM_MUSIC);
    try {
        mediaPlayer.setDatasource(url);
    } catch (IllegalArgumentexception E) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (SecurityException E) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IllegalStateException E) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException E) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    try {
        mediaPlayer.prepare();
    } catch (IllegalStateException E) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException E) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } // might take long! (for buffering,etC)

   streamButton = (ToggleButton) findViewById(R.id.playstopstream);

   streamButton.setOncheckedchangelistener(new Oncheckedchangelistener() {

    @Override
    public void oncheckedChanged(CompoundButton arg0,final Boolean ischecked) {
        // TODO Auto-generated method stub
         new Thread(new Runnable() {

            @Override
            public void run() {
                // TODO Auto-generated method stub
                if(ischecked)
                {


                    mediaPlayer.start();

                }
                else
                {
                    mediaPlayer.stop();
                    mediaPlayer.reset();



                }
            }
