怎么使图片每隔5秒自动的切换

如何使图片每隔5秒自动的切换
求交于各位大侠，我想让图片显示的区域每隔5秒就换一张图片，就像幻灯片自动播放一样
private ImageView mImageView = null;
private Integer[] MImgs = { R.drawable.image01, R.drawable.image02,
R.drawable.image03, R.drawable.image04, R.drawable.image05,
R.drawable.image06, R.drawable.image14, R.drawable.image08,
R.drawable.image09, R.drawable.image10, R.drawable.image11,
R.drawable.image12, R.drawable.image13, R.drawable.image07,
R.drawable.image16

};
Handler handler = new Handler() {

@Override
public void handleMessage(Message msg) {
switch (msg.what) {
case 1:
Bundle bundle = msg.getData();

mImageView.setImageResource(bundle.getInt("image"));
System.out.println("++++++++++++" + bundle.getInt("image"));
handler.removeMessages(1);
handler.sendEmptyMessageDelayed(1, 5000);
break;
}
super.handleMessage(msg);

}

};

class UpdateImage implements Runnable {

@Override
public void run() {
Message message = new Message();
message.what = 1;
Bundle bundle = new Bundle();
for (int i = 0; i < MImgs.length; i++) {
bundle.putInt("image", MImgs[i]);
message.setData(bundle);

}
handler.sendMessage(message);
}
}

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.five);
mImageView = (ImageView) findViewById(R.id.tupian);
// mImageView.setImageResource(R.drawable.image01);
new Thread(new UpdateImage()).start();
  }
  }
为什么我这样写只能够获得最后一张图片的ID，而后5秒更新得到的ID都是0，请各位大侠帮帮忙。

做一个timer，5秒启动一次发一个消息给handler 做一个imageview的set动作不就行了么
