1.使用eclipse建立一个默认的android工程。

2.修改layout文件
   1）打开res\layout\main.xml
   2）删除TextView
   3）加入SurfaceView
         <SurfaceView
        android:id = "@+id/surfaceView"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
         />
3.修改Java程序
   package playVideo.pack;

import android.app.Activity;
import android.os.Bundle;

import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.OutputStream;
import java.util.Iterator;
import java.util.List;

import android.content.ContentValues;
import android.content.res.Configuration;
import android.hardware.Camera;
import android.net.Uri;
import android.provider.MediaStore.Images.Media;
import android.util.Log;
import android.view.SurfaceHolder;
import android.view.SurfaceHolder.Callback;
import android.view.SurfaceView;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Toast;
import android.media.AudioManager;
import android.media.MediaPlayer;

public class PlayVideoActivity extends Activity implements SurfaceHolder.Callback{
    /** Called when the activity is first created. */

SurfaceView surfaceView;
SurfaceHolder surfaceHolder;
//String str = "/sdcard/test.mp4";

String str = "/sdcard/music/01.mp3";
MediaPlayer mediaPlayer;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
       
        surfaceView = (SurfaceView) findViewById(R.id.surfaceView);
        surfaceHolder = surfaceView.getHolder();
        surfaceHolder.addCallback(this);    
        surfaceHolder.setFixedSize(320,240);
        surfaceHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
        
        mediaPlayer = new MediaPlayer();
       
        
    }
    
    public void playVideo(String str)
    {
    mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
    mediaPlayer.setDisplay(surfaceHolder);
    try
    {
    mediaPlayer.setDataSource(str);
    mediaPlayer.prepare();
    }
    catch (Exception e)
    {
    e.printStackTrace();
    }
    mediaPlayer.start();
    }
    
    
    public void surfaceChanged(SurfaceHolder arg0, int arg1, int arg2, int arg3) {
    }
    public void surfaceCreated(SurfaceHolder arg0) {
    playVideo(str);
    }
    public void surfaceDestroyed(SurfaceHolder arg0) {
    }
}
