Android VideoPlayer

一、Android 视频播放的几种方法

1、VideoView 播放组件
（1）布局xml中添加VideoView组件

（2）AndroidManifest文件
添加访问sd卡权限
横屏 android:screenOrientation="landscape"
去掉ActionBar android:theme="@style/Theme.AppCompat.Light.NoActionBar"
（3）MainActivity.java

public class MainActivity extends Activity {    private VideoView videoView;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        videoView = findViewById(R.id.VideoView);        videoView.setVideoPath("/mnt/shared/other/family.mp4");     //设置视频路径        videoView.start();        MediaController mediaController = new MediaController(MainActivity.this,true);   //设置控制器        videoView.setMediaController(mediaController);    //用控制器初始化videoview    }}

2、MediaPlayer + SurfaceView
（1）视频文件ocean.mp4放置于res目录下的raw目录中，由于surfaceView的创建需要一定的时间，因此调用addCallback，在其创建完成时，播放器设置播放幕布并进行播放。
（2）布局XML

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

（3）MainActivity.Java

public class MainActivity extends Activity {    private SurfaceView surfaceView;   //播放幕布    private MediaPlayer mediaPlayer;  //播放器    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        surfaceView = findViewById(R.id.surfaceView);        mediaPlayer = MediaPlayer.create(MainActivity.this,R.raw.ocean);        //surfaceView的创建需要一定的时间        surfaceView.getHolder().addCallback(new SurfaceHolder.Callback() {            @Override            public void surfaceCreated(SurfaceHolder surfaceHolder) {                mediaPlayer.setDisplay(surfaceView.getHolder());                mediaPlayer.start();            }            @Override            public void surfaceChanged(SurfaceHolder surfaceHolder, int i, int i1, int i2) {            }            @Override            public void surfaceDestroyed(SurfaceHolder surfaceHolder) {            }        });        findViewById(R.id.pause).setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View view) {                mediaPlayer.pause();            }        });        findViewById(R.id.play).setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View view) {                mediaPlayer.start();            }        });    }}

3、MediaPlayer + SurfaceView + MediaController
（1）布局XML
只有一个SurfaceView组件

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

（2）MainActivity.java
自己定义MediaController，相当于将MediaPlayer 的控制交给MediaController。

public class MainActivity extends Activity implements MediaController.MediaPlayerControl {    private SurfaceView surfaceView;   //播放幕布    private MediaPlayer mediaPlayer;    private MediaController mediaController;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        surfaceView = findViewById(R.id.surfaceView);        mediaPlayer = MediaPlayer.create(MainActivity.this,R.raw.ocean);        //surfaceView的创建需要一定的时间        surfaceView.getHolder().addCallback(new SurfaceHolder.Callback() {            @Override            public void surfaceCreated(SurfaceHolder surfaceHolder) {                mediaPlayer.setDisplay(surfaceView.getHolder());                mediaPlayer.start();            }            @Override            public void surfaceChanged(SurfaceHolder surfaceHolder, int i, int i1, int i2) {            }            @Override            public void surfaceDestroyed(SurfaceHolder surfaceHolder) {            }        });        mediaController = new MediaController(MainActivity.this);        mediaController.setMediaPlayer(MainActivity.this);        mediaController.setAnchorView(findViewById(R.id.root));        mediaController.setEnabled(true);    }    @Override    public void start() {        mediaPlayer.start();    }    @Override    public void pause() {        mediaPlayer.pause();        //显示广告、开通会员等    }    @Override    public int getDuration() {        return mediaPlayer.getDuration();    }    @Override    public int getCurrentPosition() {        return mediaPlayer.getCurrentPosition();    }    @Override    public void seekTo(int i) {        mediaPlayer.seekTo(i);    }    @Override    public boolean isPlaying() {        return mediaPlayer.isPlaying();    }    @Override    public int getBufferPercentage() {        return 0;    }    @Override    public boolean canPause() {        return true;    }    @Override    public boolean canSeekBackward() {        return true;    }    @Override    public boolean canSeekForward() {        return true;    }    @Override    public int getAudioSessionId() {        return 0;    }    @Override    public boolean onTouchEvent(MotionEvent event) {        mediaController.show();  //显示mediaController        //将触摸事件交给mediaController去处理而不是activity        return mediaController.onTouchEvent(event);    }}
