package MyTimer.code;

import java.util.Timer;
import java.util.TimerTask;

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

public class MainActivity extends Activity {

private int iCount = 0;

Timer timer = new Timer();
Handler handler = new Handler()

@Override
public void handleMessage(Message msg )

case 1:
if( iCount % 2 == 0 )
setTitle("kiss you");

setTitle("kiss me");
iCount ++;

break;
}

super.handleMessage(msg);
}
};

TimerTask task = new TimerTask()
{
@Override
public void run()
{
Message msg = new Message();
msg.what = 1;
handler.sendMessage(msg);
}
};

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);

timer.schedule(task,1000,5000);// 1000 1秒之后执行 5000 周期为5秒
