MainActivity如下:

package cc.test;

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

import android.app.Activity;
import android.os.Bundle;
/**
* Demo描述:
* Timer和TimerTask使用完整示例
*/
public class MainActivity extends Activity {
private Timer mTimer;
private TimerTask mTimerTask;
private int count=0;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
init();
}

private void init() {
mTimer = new Timer();
mTimerTask = new TimerTask() {
@Override
public void run() {
count++;
System.out.println("---> count=" + count);
if (count == 15) {
mTimer.cancel();
System.out.println("---> 取消定时任务");
}
}
};
//开始一个定时任务
mTimer.schedule(mTimerTask, 2000, 1500);
}
}

main.xml如下:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"

<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
