Android多媒体教程之播放视频的四种方法

本文主要给大家介绍的是关于Android播放视频的四种方法，分享出来供大家参考学习，下面来一起看看详细的介绍：

一、通过intent的方式，调用系统自带的播放器

Uri uri = Uri.parse("/storage/emulated/0/DCIM/Camera/20170521_200117.mp4");//调用系统自带的播放器Intent intent = new Intent(Intent.ACTION_VIEW);intent.setDataAndType(uri, "/storage/emulated/0/DCIM/Camera/20170521_200117.mp4");startActivity(intent);

二、使用VideoView

布局文件

Activitypublic class VideoPlayByVVActivity extends AppCompatActivity {

}}

三、MediaPlayer + SurfaceView

Activitypublic class VideoPlayBySurActivity extends AppCompatActivity implements View.OnClickListener {

private SurfaceView mSurfaceView;private MediaPlayer mMediaPlayer;

@Override protected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_video_play_by_sur);mSurfaceView = (SurfaceView) findViewById(R.id.surface_view);findViewById(R.id.stop).setOnClickListener(this);findViewById(R.id.pasue).setOnClickListener(this);

findViewById(R.id.play).setOnClickListener(this);

init();}

private void init() {mMediaPlayer = new MediaPlayer();

mSurfaceView.getHolder().addCallback(new SurfaceHolder.Callback() {@Override public void surfaceCreated(SurfaceHolder holder) {play();}

@Override public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) {

}

@Override public void surfaceDestroyed(SurfaceHolder holder) {

}});}

@Override public void onClick(View v) {switch (v.getId()){case R.id.stop:stop();break;case R.id.play:if(!mMediaPlayer.isPlaying()){play();}break;case R.id.pasue:pasue();break;

}}

public void stop(){if(mMediaPlayer.isPlaying()){mMediaPlayer.stop();}}

public void pasue(){if(mMediaPlayer.isPlaying()){mMediaPlayer.pause();}else{mMediaPlayer.start();}}

public void play(){

String path = "/storage/emulated/0/DCIM/Camera/20170521_200117.mp4";try {mMediaPlayer.reset();mMediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);//设置需要播放的视频mMediaPlayer.setDataSource(this, Uri.parse(path));//把视频画面输出到SurfaceView mMediaPlayer.setDisplay(mSurfaceView.getHolder());mMediaPlayer.prepare();mMediaPlayer.start();

} catch (IOException e) {e.printStackTrace();}}}

四、 MediaPlayer + TextureView

Activitypublic class VideoPlayByTextrueViewActivity extends AppCompatActivity implements MediaPlayer.OnPreparedListener, MediaPlayer.OnInfoListener, MediaPlayer.OnBufferingUpdateListener {

private TextureView mTextureView;private ImageView mImageVideo;private Surface mSurface;private MediaPlayer mMediaPlayer;private static String path = "/storage/emulated/0/DCIM/Camera/20170521_200117.mp4";

@Override protected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_video_play_by_textrue_view);

mTextureView = (TextureView) findViewById(R.id.texture_view);

mImageVideo = (ImageView) findViewById(R.id.video_image);

init();}

private void init() {

mTextureView.setSurfaceTextureListener(new TextureView.SurfaceTextureListener() {@Override public void onSurfaceTextureAvailable(SurfaceTexture surfaceTexture, int width, int height) {mSurface = new Surface(surfaceTexture);

Log.e("tag", "---- onSurfaceTextureAvailable");

play();}

@Override public void onSurfaceTextureSizeChanged(SurfaceTexture surface, int width, int height) {Log.e("tag", "---- onSurfaceTextureSizeChanged");}

@Override public boolean onSurfaceTextureDestroyed(SurfaceTexture surface) {mTextureView=null;mSurface=null;mMediaPlayer.stop();mMediaPlayer.release();return false;}

@Override public void onSurfaceTextureUpdated(SurfaceTexture surface) {

}});

}

public void play(){

mMediaPlayer = new MediaPlayer();

try {mMediaPlayer.setDataSource(getApplicationContext(), Uri.parse(path));mMediaPlayer.setSurface(mSurface);mMediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);

mMediaPlayer.setOnPreparedListener(this);mMediaPlayer.setOnInfoListener(this);mMediaPlayer.setOnBufferingUpdateListener(this);

mMediaPlayer.prepareAsync();

} catch (IOException e) {e.printStackTrace();}

}

@Override public void onPrepared(MediaPlayer mp) {

mImageVideo.setVisibility(View.GONE);mMediaPlayer.start();}

@Override public boolean onInfo(MediaPlayer mp, int what, int extra) {return false;}

@Override public void onBufferingUpdate(MediaPlayer mp, int percent) {
