Android 视频播放

1.使用系统自带的VideoView播放MP4，3pg等视频文件

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView android:layout_width="fill_parent"
android:layout_height="wrap_content" android:text="@string/hello" />
<VideoView android:id="@+id/VideoView01"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
</VideoView>
</LinearLayout>

Java代码：

package com.Aina.Android;

import android.app.Activity;
import android.net.Uri;
import android.os.Bundle;
import android.os.Environment;
import android.widget.MediaController;
import android.widget.VideoView;

public class Test extends Activity {
/** Called when the activity is first created. */
private VideoView mVideoView = null;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mVideoView = (VideoView) this.findViewById(R.id.VideoView01);
mVideoView.setVideoPath(Environment.getExternalStorageDirectory()+"/moto_0012.3gp");//本地资源
// mVideoView.setVideoURI(Uri.parse("http://192.168.0.132:8080/mp.mp4"));//网络资源
mVideoView.setMediaController(new MediaController(Test.this));//设置模式，播放进度条
mVideoView.requestFocus();
mVideoView.start();
}
}

2.使用SurfaceView播放MP4，3pg等视频文件

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView android:layout_width="fill_parent"
android:layout_height="wrap_content" android:text="@string/hello" />
<SurfaceView android:id="@+id/surfaceView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center">
</SurfaceView>
</LinearLayout>

package com.Aina.Android;

import android.app.Activity;
import android.media.AudioManager;
import android.media.MediaPlayer;
import android.media.MediaPlayer.OnBufferingUpdateListener;
import android.media.MediaPlayer.OnCompletionListener;
import android.net.Uri;
import android.os.Bundle;
import android.util.Log;
import android.view.SurfaceHolder;
import android.view.SurfaceView;

public class Test extends Activity implements OnBufferingUpdateListener,
OnCompletionListener, MediaPlayer.OnPreparedListener,
SurfaceHolder.Callback {
private int width = 0;
private int height = 0;
private MediaPlayer mMediaPlayer = null;
private SurfaceView mSurfaceView = null;
private SurfaceHolder holder = null;
private String path = "";

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mSurfaceView = (SurfaceView) this.findViewById(R.id.surfaceView);
holder = mSurfaceView.getHolder();
holder.addCallback(this);
holder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);// 设置风格
}

public void playVedio() {
try {
path = android.os.Environment.getExternalStorageDirectory()
+ "/moto_0012.3gp";
mMediaPlayer = new MediaPlayer();
// mMediaPlayer.setDataSource(path);
mMediaPlayer.setDataSource(this, Uri.parse("http://192.168.0.132:8080/mp.mp4"));
mMediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
mMediaPlayer.setDisplay(holder);
mMediaPlayer.prepare();// 准备
Log.i("TAG-Duration", mMediaPlayer.getDuration()+"");
mMediaPlayer.setOnBufferingUpdateListener(this);
mMediaPlayer.setOnCompletionListener(this);
mMediaPlayer.setOnPreparedListener(this);
} catch (Exception ex) {

}
}

public void onBufferingUpdate(MediaPlayer mp, int percent) {
// TODO Auto-generated method stub
Log.i("TAG-onBufferingUpdate", percent+"|"+mMediaPlayer.getCurrentPosition());
}

public void onCompletion(MediaPlayer mp) {
// TODO Auto-generated method stub
Log.i("TAG-onCompletion", "Completion");
}

public void onPrepared(MediaPlayer mp) {
// TODO Auto-generated method stub
width = mMediaPlayer.getVideoWidth();
height = mMediaPlayer.getVideoHeight();
if(width !=0 && height !=0){
holder.setFixedSize(width, height);//设置视频高宽
mMediaPlayer.start();
Log.i("TAG-Duration2", mMediaPlayer.getDuration()+"");
}
}

public void surfaceChanged(SurfaceHolder holder, int format, int width,
int height) {
// TODO Auto-generated method stub

}

public void surfaceCreated(SurfaceHolder holder) {
// TODO Auto-generated method stub
playVedio();
}

public void surfaceDestroyed(SurfaceHolder holder) {
// TODO Auto-generated method stub
Log.i("TAG-surfaceDestroyed", "surfaceDestroyed");
}

@Override
protected void onPause() {
super.onPause();
if(mMediaPlayer != null){
if(mMediaPlayer.isPlaying()){
mMediaPlayer.stop();
}
mMediaPlayer.reset();
mMediaPlayer.release();
mMediaPlayer = null;
}
}

}
