android TimerTask 的简单应用

package com.android.testapp;

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

public class Tesdt {

private Timer mTimer;
private TimerTask mTimerTask;

public void StartLockWindowTimer() {
if (mTimer != null) {
if (mTimerTask != null) {
mTimerTask.cancel(); // 将原任务从队列中移除
}

mTimerTask = new TimerTask() {

@Override
public void run() {
// TODO Auto-generated method stub

}

};

mTimer.schedule(mTimerTask, 3000);
}
}

}
