首先，须要启动一个后台服务，用于注册一个BroadcastReceiverandroid

这个BroadcastReceiver用于监听Intent.ACTION_SCREEN_OFFapp

这样在发生这个事件Intent.ACTION_SCREEN_OFF 也就是用户锁屏或者屏幕上锁时触发。ide

Service中注册BroadcastReceiver代码函数

package com.pingbao;

import android.app.KeyguardManager;

import android.app.Service;

import android.app.KeyguardManager.KeyguardLock;

import android.content.BroadcastReceiver;

import android.content.Context;

import android.content.Intent;

import android.content.IntentFilter;

import android.os.IBinder;

import android.util.Log;

public class ZyScreenService extends Service {

KeyguardManager mKeyguardManager = null;

private KeyguardLock mKeyguardLock = null;

@Override

public IBinder onBind(Intent arg0) {

// TODO Auto-generated method stub

return null;
