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

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

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


</RelativeLayout>

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

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
 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">
 <SurfaceView
  android:id="@+id/surface_view"
  android:layout_width="180dp"
  android:layout_height="wrap_content"/>
 <LinearLayout
  android:layout_alignParentBottom="true"
  android:layout_width="match_parent"
  android:layout_height="40dp">


  <Button
   android:id="@+id/stop"
   android:text="stop"
   android:layout_weight="1"
   android:layout_width="0dp"
   android:layout_height="match_parent"/>
  <Button
   android:id="@+id/play"
   android:text="play"
   android:layout_weight="1"
   android:layout_width="0dp"
   android:layout_height="match_parent"/>
  <Button
   android:id="@+id/pasue"
   android:text="pasue"
   android:layout_weight="1"
   android:layout_width="0dp"
   android:layout_height="match_parent"/>

 </LinearLayout>
</RelativeLayout>

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

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


 <TextureView
  android:id="@+id/texture_view"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"/>

 <ImageView
  android:id="@+id/video_image"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:src="@drawable/all_darkbackground"/>
</RelativeLayout>

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 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) {

 }
}
