这篇文章将为大家详细讲解有关Android如何实现播放视频，小编觉得挺实用的，因此分享给大家做个参考，希望大家阅读完这篇文章后可以有所收获。
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) {
}
