首先,创建sdcard镜像文件,在命令行下输入:

mksdcard 512M c:\sdcard.img命令

启动eclipse,单击window/preferences菜单,找到Launch项,

在Default emulator options 中填上 c:\sdcard.img

然后OK

找到eclipse的File Explorer 窗口, 在/mnt/sdcard中导入 3gp文件(我用的是zhoupkding.3gp)

然后开始程序:

界面上:

android:orientation="vertical"

android:layout_width="fill_parent"

android:layout_height="fill_parent"

>

android:id="@+id/surfaceView"

android:layout_width="320px"

android:layout_height="200px"

/>

android:layout_width="fill_parent"

android:layout_height="wrap_content"

>

android:id="@+id/play"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:text="播放"

/>

android:id="@+id/pause"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:text="暂停"

/>

源码: public class VideoPlayActivity extends Activity implements OnClickListener, SurfaceHolder.Callback{

// 视频的路径

String videoPath = "/mnt/sdcard/zhoupkding.3gp";

Button playButton;

Button pauseButton;

boolean isPause = false;

SurfaceHolder surfaceHolder;

MediaPlayer mediaPlayer;

SurfaceView surfaceView;

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

playButton = (Button)findViewById(R.id.play);

playButton.setOnClickListener(this);

pauseButton = (Button)findViewById(R.id.pause);

pauseButton.setOnClickListener(this);

// 让window自己设置程序的背景样式

getWindow().setFormat(PixelFormat.UNKNOWN);

surfaceView = (SurfaceView)findViewById(R.id.surfaceView);

surfaceHolder = surfaceView.getHolder();

surfaceHolder.addCallback(this);

// 让surfaceView确定大小

surfaceHolder.setFixedSize(176, 144);

//Surface type: creates a "push" surface,

//that is a surface that doesn't owns its buffers.

//With such a surface lockCanvas will fail.

// 不加这个没有视频,只有声音,文档上说是需要的时候可以自动设置,但是并没有

surfaceHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);

mediaPlayer = new MediaPlayer();

}

@Override

public void onClick(View v) {

if (v == playButton) {

isPause = false;

playVideo(videoPath);

} else if (v == pauseButton) {

if (isPause == false) {

mediaPlayer.pause();

isPause = true;

} else {

mediaPlayer.start();

isPause = false;

}

}

}

private void playVideo(String path) {

if (mediaPlayer.isPlaying() == true) {

mediaPlayer.reset();

}

mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);

//Sets the SurfaceHolder to use for displaying the video portion of the media.

mediaPlayer.setDisplay(surfaceHolder);

try {

mediaPlayer.setDataSource(path);

mediaPlayer.prepare();

} catch (Exception e) {

e.printStackTrace();

}

mediaPlayer.start();

}

@Override

public void surfaceChanged(SurfaceHolder holder, int format, int width,

int height) {

}

@Override

public void surfaceCreated(SurfaceHolder holder) {

}

@Override

public void surfaceDestroyed(SurfaceHolder holder) {

}

}
