我正在开发一个应用程序，我想在其中播放直播电台。我有一个 url，我将使用它来播放广播和播放。我有一个播放按钮，点击我想播放的收音机。为此，我编写了一些根本不起作用的代码。这是我的代码：

mp = new MediaPlayer();
try {

    mp.setOnPreparedListener(this);
    Log.d("Testing", "start111");
    mp.setAudioStreamType(AudioManager.STREAM_MUSIC);
    String url="xxxxxx";
    mp.setDataSource(url);
    mp.prepareAsync();
} catch (IllegalArgumentException e) {
    e.printStackTrace();
    Log.d("Testing", "Exception ::: 1111 "+e.getMessage());
} catch (IllegalStateException e) {
    Log.d("Testing", "Exception ::: 2222 "+e.getMessage());
    e.printStackTrace();
} catch (IOException e) {
    Log.d("Testing", "IOException ::: 3333 "+e.getMessage());
    e.printStackTrace();
}

谁能帮帮我吗？？

您可以找到有关无线电流的良好信息。 Github 广播流媒体示例

还有一个 SOF 中的问题，它也可以帮助 Stackoverflow 无线电流示例

希望它会有所帮助。谢谢

尝试这个。

public class RadioStream extends Activity {

    private final static String stream = "http://bbcmedia.ic.llnwd.net/stream/bbcmedia_radio2_mf_p";
    Button play;
    MediaPlayer mediaPlayer;
    boolean started = false;
    boolean prepared = false;

    /**
     * Called when the activity is first created.
     */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_radio_stream);

        play = (Button) findViewById(R.id.play);
        play.setEnabled(false);
        play.setText("Loading..");
        mediaPlayer = new MediaPlayer();
        mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);

        play.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

                if (started) {
                    mediaPlayer.pause();
                    started = false;
                    play.setText("Play");
                } else {
                    mediaPlayer.start();
                    started = true;
                    play.setText("Pause");
                }

            }
        });

        new PlayTask().execute(stream);
    }

    @Override
    protected void onPause() {
        super.onPause();
       /* if(started)
            mediaPlayer.pause();*/

    }

    @Override
    protected void onResume() {
        super.onResume();
        /*if(started)
            mediaPlayer.start();*/
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        // mediaPlayer.release();
    }

    private class PlayTask extends AsyncTask<String, Void, Boolean> {

        @Override
        protected Boolean doInBackground(String... strings) {

            try {
                mediaPlayer.setDataSource(strings[0]);
                mediaPlayer.prepare();
                prepared = true;
            } catch (IOException e) {
                e.printStackTrace();
            }
            return prepared;
        }

        @Override
        protected void onPostExecute(Boolean aBoolean) {
            super.onPostExecute(aBoolean);
            play.setEnabled(true);
            play.setText("Play");

        }
    }
}

请尝试下面的代码，并在您的活动创建时或按钮的 onclick 侦听器处调用给定的方法。请记住处理停止和启动按钮，imgV 是我的按钮的 imageView。

 private MediaPlayer player;
private void startMediaPlayer() {
    String url = "http:yoururl.com"; // your URL here
    mediaPlayer = new MediaPlayer();
    mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
    try {
        mediaPlayer.setDataSource(url);
    } catch (IllegalArgumentException e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
    } catch (SecurityException e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
    } catch (IllegalStateException e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
    } catch (IOException e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
    }
    if(isPlaying){
        try {
            mediaPlayer.prepareAsync();
            progress.setVisibility(View.VISIBLE);
        } catch (IllegalStateException e1) {
            // TODO Auto-generated catch block
            e1.printStackTrace();
        }
        mediaPlayer.setOnPreparedListener(new OnPreparedListener() {

            public void onPrepared(MediaPlayer mp) {
                mediaPlayer.start();
            }
        });
    }
    mediaPlayer.setOnBufferingUpdateListener(new OnBufferingUpdateListener() {

        public void onBufferingUpdate(MediaPlayer mp, int percent) {
        }
    });
}

boolean isPlaying = true;
 private void startPlaying() {
    isPlaying = true;
    mediaPlayer.prepareAsync();
    mediaPlayer.setOnPreparedListener(new OnPreparedListener() {
        public void onPrepared(MediaPlayer mp) {
            mediaPlayer.start();
        }
    });
    imgV.setImageResource(R.drawable.stop);
}

private void stopPlaying() {
    if (mediaPlayer.isPlaying()) {
        isPlaying = false;
        mediaPlayer.stop();
        mediaPlayer.release();
        initializeMediaPlayer();
    }
    imgV.setImageResource(R.drawable.play);
}
