android播放视频

android播放视频用的是SurfaceView和MediaPlayer

具体实现和播放音乐一样

package com.example.videoplayer;


import android.media.MediaPlayer;
import android.os.Bundle;
import android.app.Activity;
import android.view.SurfaceHolder;
import android.view.SurfaceHolder.Callback;
import android.view.SurfaceView;

public class MainActivity extends Activity {
    
    private MediaPlayer player;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        SurfaceView sv = (SurfaceView) findViewById(R.id.sfv);
        //拿到surfaceview的控制器
        final SurfaceHolder sh = sv.getHolder();
        sh.addCallback(new Callback() {
            
            
            //surfaceView销毁时调用
            @Override
            public void surfaceDestroyed(SurfaceHolder holder) {
                //每次surfaceview销毁时，同时停止播放视频
                if(player!=null){
                    player.stop();
                    player.release();
                    player=null;
                }
                
            }
            //surfaceView创建时调用
            @Override
            public void surfaceCreated(SurfaceHolder holder) {
                //每次surfaceView创建时才去播放视频
                if(player == null){
                    player = new MediaPlayer();
                    player.reset();
                    try {
                        player.setDataSource("sdcard/1.mp4");
                        player.setDisplay(sh);
                        player.prepare();
                        player.start();
                    } catch (Exception e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    } 
                }
                
            }
            //surfaceView结构改变时调用
            @Override
            public void surfaceChanged(SurfaceHolder holder, int format, int width,
                    int height) {
                // TODO Auto-generated method stub
                
            }
        });
        
    }
