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

xmlns:android="http://schemas.android.com/apk/res/android"

xmlns:tools="http://schemas.android.com/tools"

android:id="@+id/activity\_video\_play\_by\_vv"

android:layout\_width="match\_parent"

android:layout\_height="match\_parent">

android:id="@+id/video\_view"

android:layout\_width="wrap\_content"

android:layout\_height="wrap\_content"/>

Activity

public class VideoPlayByVVActivity extends AppCompatActivity \{

private VideoView mVideoView;

@Override

protected void onCreate(Bundle savedInstanceState) \{

super.onCreate(savedInstanceState);

// requestWindowFeature(Window.FEATURE\_NO\_TITLE); //去掉 title

// setRequestedOrientation(ActivityInfo.SCREEN\_ORIENTATION\_LANDSCAPE); //设置全屏

// getWindow().addFlags(WindowManager.LayoutParams.FLAG\_KEEP\_SCREEN\_ON); //设置屏幕常亮

setContentView(R.layout.activity\_video\_play\_by\_vv);

mVideoView = (VideoView) findViewById(R.id.video\_view);

init();

private void init() \{

String path = "/storage/emulated/0/DCIM/Camera/20170521\_200117.mp4";

Uri uri = Uri.parse(path);

mVideoView.setVideoPath(path);

mVideoView.start();

mVideoView.requestFocus();

三、MediaPlayer + SurfaceView

xmlns:android="http://schemas.android.com/apk/res/android"

xmlns:tools="http://schemas.android.com/tools"

android:id="@+id/activity\_video\_play\_by\_sur"

android:layout\_width="match\_parent"

android:layout\_height="match\_parent">

android:id="@+id/surface\_view"

android:layout\_width="180dp"

android:layout\_height="wrap\_content"/>

android:layout\_alignParentBottom="true"

android:layout\_width="match\_parent"

android:layout\_height="40dp">

android:id="@+id/stop"

android:text="stop"

android:layout\_weight="1"

android:layout\_width="0dp"

android:layout\_height="match\_parent"/>

android:id="@+id/play"

android:text="play"

android:layout\_weight="1"

android:layout\_width="0dp"

android:layout\_height="match\_parent"/>

android:id="@+id/pasue"

android:text="pasue"

android:layout\_weight="1"

android:layout\_width="0dp"

android:layout\_height="match\_parent"/>

Activity

public 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

xmlns:android="http://schemas.android.com/apk/res/android"

xmlns:tools="http://schemas.android.com/tools"

android:id="@+id/activity\_video\_play\_by\_textrue\_view"

android:layout\_width="match\_parent"

android:layout\_height="match\_parent">

android:id="@+id/texture\_view"

android:layout\_width="wrap\_content"

android:layout\_height="wrap\_content"/>

android:id="@+id/video\_image"

android:layout\_width="match\_parent"

android:layout\_height="match\_parent"

android:src="@drawable/all\_darkbackground"/>

Activity

public 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 height) \{

mSurface = new Surface(surfaceTexture);

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

play();

@Override

public void onSurfaceTextureSizeChanged(SurfaceTexture surface,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) \{
