如何停止MediaPlayer流然后重新启动它？ Android的 [英] How to stop MediaPlayer stream and then restart it? Android

问题描述

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？

I am making a simple app to play a online radio stream. I know how to set up the stream. Here is my code so far. It sets up the stream and plays it fine. But if I hit stop, I cannot get it to start again. Am I missing something obvious?

final MediaPlayer mediaPlayer = new MediaPlayer();
    mediaPlayer.setAudioStreamType(AudioManager.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();



                }
            }

推荐答案

老问题，但我遇到了这个问题。只需使用暂停停止，然后按在重新启动之前seekTo（0）：

Old question, but I came across it looking for this. Just use pause to stop, followed by seekTo(0) before restarting:

mediaPlayer.seekTo(0);
mediaPlayer.start();

每次都不需要再次准备录音机。

Works without having to prepare the recorder again every time.
