Android 带有MediaPlayer的MediaController

我想要媒体控件，例如播放/暂停我正在应用程序中播放的流媒体音频。我正在使用MediaPlayer流式播放音频

有人能提供一个关于如何将MediaController与MediaPlayer一起使用的代码片段吗

谢谢

与从中提取的代码一样简单。他们使用VideoView而不是MediaPlayer，这为您节省了几行代码：

布局：

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout android:id="@+id/LinearLayout01"
    android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android"
    android:paddingLeft="2px" android:paddingRight="2px"
    android:paddingTop="2px" android:paddingBottom="2px"
    android:layout_width="fill_parent" android:orientation="vertical">

    <VideoView android:layout_height="fill_parent"
        android:layout_width="fill_parent" android:id="@+id/VideoView"></VideoView>

</LinearLayout>

就这些。只需将mp4视频链接替换为流式视频url即可

在媒体播放器中添加媒体控制器非常简单。让您的活动实现MediaPlayerControl并添加未实现的方法。代码如下：

我在这里使用Api演示中的代码

我可以用它来流式传输rtsp视频吗？如何包括扩展到全屏功能，如youtube[]方形框？似乎这是专门用于视频的，而问题是关于音频的，最好编辑答案以适合。说真的，为什么视频视图中有这么多答案。关于videosHere从未提及的问题是一个不使用VideoView而是使用MediaPlayer和MediaController播放音频的示例：

public class VideoPlayerController extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.video);

        VideoView videoView = (VideoView) findViewById(R.id.VideoView);
        MediaController mediaController = new MediaController(this);
        mediaController.setAnchorView(videoView);
// Set video link (mp4 format )
        Uri video = Uri.parse("mp4 video link");
        videoView.setMediaController(mediaController);
        videoView.setVideoURI(video);
        videoView.start();

    }
}

public class ActivityVedioPlay extends Activity implements
        OnBufferingUpdateListener, OnCompletionListener, OnPreparedListener,
        OnVideoSizeChangedListener, SurfaceHolder.Callback, MediaPlayerControl {
.....

    private MediaPlayer mMediaPlayer;
    private MediaController mcontroller;
    private Handler handler = new Handler();
.....
@Override
    public boolean onTouchEvent(MotionEvent event) {
        /*
         * the MediaController will hide after 3 seconds - tap the screen to
         * make it appear again
         */
        mcontroller.show();
        return false;
    }
......
private void playVideo() {
        doCleanUp();
        try {
            path = getIntent().getStringExtra("url");
            if (path == "") {
                Toast.makeText(ActivityVedioPlay.this, "URL Not found",
                        Toast.LENGTH_LONG).show();
            }
            mMediaPlayer = new MediaPlayer();
            mMediaPlayer.setDataSource(path);
            mMediaPlayer.setDisplay(holder);
            mMediaPlayer.prepare();
            mMediaPlayer.setOnBufferingUpdateListener(this);
            mMediaPlayer.setOnCompletionListener(this);
            mMediaPlayer.setOnPreparedListener(this);
            mMediaPlayer.setScreenOnWhilePlaying(true);
            mMediaPlayer.setOnVideoSizeChangedListener(this);
            mMediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
            mcontroller = new MediaController(this);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
......

public void onPrepared(MediaPlayer mediaplayer) {
        Log.d(TAG, "onPrepared called");
        mIsVideoReadyToBePlayed = true;
        if (mIsVideoReadyToBePlayed && mIsVideoSizeKnown) {
            startVideoPlayback();
        }
        mcontroller.setMediaPlayer(this);
        mcontroller.setAnchorView(findViewById(R.id.mediaplayer_surfaceview_container));
        handler.post(new Runnable() {

            public void run() {
                mcontroller.setEnabled(true);
                mcontroller.show();
            }
        });
    }

    public void start() {
        mMediaPlayer.start();
    }

        mMediaPlayer.pause();
