本文介绍了如何在Android应用中使用VideoView和SurfaceView播放MP4及3gp格式的视频文件。通过XML布局定义视图，并在Java代码中进行初始化和配置，包括设置视频路径、播放控制器等。

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>


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;
		}
	}

}
