Android的如何使用/显示的MediaController与SurfaceView和MediaPlayer的视频？ [英] Android how to use/show MediaController with SurfaceView and MediaPlayer for video?

问题描述

我要使用的MediaPlayer播放视频，而不是一个VideoView。 我在XML布局，并在活动侧的MediaPlayer和的MediaController一个SurfaceView。

I have to use MediaPlayer to play a video, NOT a VideoView. I have a SurfaceView in Xml Layout and on the Activity side a MediaPlayer and a MediaController.

我coudldn't找到一种方法，使用的MediaController与SurfaceView和MediaPlayer的。它与VideoView那么容易，但无法弄清楚如何使用MediaPlayer的使用。

I coudldn't find a way to use MediaController with SurfaceView and MediaPlayer. It is so easy with VideoView but cant figure out how to use with MediaPlayer.

我发现网上的例子，但它们都是关于播放音频，视频不

I have found examples online but they are all about playing audio, not video.

这是surfaceCreated方法，在那里我创建的MediaPlayer

This is surfaceCreated method where i create the MediaPlayer

@Override
    public void surfaceCreated(SurfaceHolder holder) {
        try {
            mMediaPlayer = new MediaPlayer();
            mMediaPlayer.setDisplay(mSurfaceHolder);
            mMediaPlayer.setDataSource(this, Uri.parse(mUrl));
            mMediaPlayer.setOnPreparedListener(this);
            mMediaPlayer.prepare();
            mMediaController = new MediaController(this);

        } catch (Exception e) {
            Log.e(TAG, "MediaPlayer Prepare: " + e.getMessage());
        }
    }

和此有关的MediaPlayer prepared方法

and this MediaPlayer onPrepared method

@Override
    public void onPrepared(MediaPlayer mp) {

        mVideoWidth = mp.getVideoWidth();
        mVideoHeight = mp.getVideoHeight();
        mSurfaceHolder.setFixedSize(mVideoWidth, mVideoHeight);
        startVideoPlayback();

        mMediaController.setMediaPlayer(this);              

        handler.post(new Runnable() {

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

在code以上不显示的MediaController上SurfaceView。
我怎样才能做到这一点？

The code above doesn't show the MediaController on SurfaceView.
How can i achieve this?

在此先感谢。

推荐答案

有关，你必须落实活动

OnBufferingUpdateListener, OnCompletionListener, OnPreparedListener,
OnVideoSizeChangedListener, SurfaceHolder.Callback, MediaPlayerControl

检查以下工作code

check below working code

package com.example.demo;
import android.app.Activity;
import android.media.AudioManager;
import android.media.MediaPlayer;
import android.media.MediaPlayer.OnBufferingUpdateListener;
import android.media.MediaPlayer.OnCompletionListener;
import android.media.MediaPlayer.OnPreparedListener;
import android.media.MediaPlayer.OnVideoSizeChangedListener;
import android.net.Uri;
import android.os.Bundle;
import android.os.Handler;
import android.view.MotionEvent;
import android.view.SurfaceHolder;
import android.view.SurfaceView;
import android.view.View;
import android.widget.MediaController;
import android.widget.MediaController.MediaPlayerControl;
import android.widget.ProgressBar;

public class MainActivity extends Activity implements  OnBufferingUpdateListener, OnCompletionListener, OnPreparedListener,
OnVideoSizeChangedListener, SurfaceHolder.Callback, MediaPlayerControl{
    String url = "your video url";
    MediaPlayer mMediaPlayer ;

    SurfaceHolder holder ;
    private ConstantAnchorMediaController controller = null;

        progressBar1 = (ProgressBar)findViewById(R.id.progressBar1);
        SurfaceView v = (SurfaceView) findViewById(R.id.surface); 
        handler = new Handler();
        holder = v.getHolder(); 
        holder.addCallback(this);
        playVideo();

    }
    private void playVideo() {
