如何实现android程序一段时间无操作后的功能自定义

文章目录

  1. 1. 方法一：用handler+onTouchEvent实现延时发送请求
  2. 2. 方法二：通过PowerManager.WakeLock实现
  3. 3. 方法三：使用双线程来实现 (时间超时或者在接收到锁屏广播的时候显示)

项目中遇见一个这样的需求，就是当软件在一定时间没有操作时候需要弹出广告页面，当点击广告页面时又进行软件操作，也就是广告要在软件打开并且处于未操作状态才会出来。

方法一：用handler+onTouchEvent实现延时发送请求

这个操作最好放到BaseActivity里进行。

private Handler handler = new Handler();
private long time=1000*60*5;
@Override
public boolean onTouchEvent(MotionEvent event) {
    switch (event.getAction()) {
        case MotionEvent.ACTION_DOWN:
            handler.removeCallbacks(runnable);
            break;
        case MotionEvent.ACTION_UP:
            startAD();
            break;
    }
    return super.onTouchEvent(event);
}
private Runnable runnable = new Runnable() {
    @Override
    public void run() {
       跳转到广告页面
    }
};
public void startAD() {
    handler.removeCallbacks(runnable);
    handler.postDelayed(runnable, time);
}

方法二：通过PowerManager.WakeLock实现

判断屏幕是否变暗的这个思路去实现。

方法三：使用双线程来实现 (时间超时或者在接收到锁屏广播的时候显示)

可以在application或者activity的oncreated方法里面启动监听。

下面是启动一个服务，当用户按锁屏键锁屏的时候会发送一个广播，我们在服务中接受到广播后可以屏蔽系统的锁屏，显示我们自己的锁屏：
