Question

我尝试使用Android MediaPlayer服务来播放音乐。一切都很好，唯一的问题是MediaPlayer正在播放时按下按钮导致强制关闭并且下方at android.media.MediaPlayer.isPlaying(Native Method)是我要播放的代码以及我如何尝试停止和关闭媒体播放器，任何想法？

播放：

private class Stream extends AsyncTask<String, String, String> {
    @Override
    protected void onPreExecute() {
        super.onPreExecute();
    }

    @Override
    protected String doInBackground(String... params) {
        try {
            mp.reset();
            mp.setDataSource(url);
            mp.prepare();
            mp.start();
            songProgressBar.setProgress(0);
            songProgressBar.setMax(100);
            updateProgressBar();
        } catch (Exception e) {
        }
        return null;
    }

    @Override
    protected void onPostExecute(String result) {
        mHandler.postDelayed(timeUpdate, 100);
    }
}

闭合：

@Override
protected void onDestroy() {
    super.onDestroy();
    if (mp != null) {
        mp.stop();
        mp.release();
    }
    finish();
}

@Override
public void onBackPressed() {
    super.onBackPressed();
    onDestroy();
}

Answer 1

替换

@Override
public void onBackPressed() {
    super.onBackPressed();
    onDestroy();
}

与

@Override
public void onBackPressed() {
if (mp != null) {
        mp.stop();
        mp.release();
    }
    finish();
    super.onBackPressed();
}

试试吧......

尝试实施onkeydown事件可能会有所帮助：

public boolean onKeyDown(int keyCode, KeyEvent event) {
        if (mp != null) {
            mp.stop();
            mp.release();
        }
        finish();
        return super.onKeyDown(keyCode, event);
    }

无法关闭android MediaPlayer
