Android ScreenLockReceiver监听锁屏功能示例

本文实例讲述了android screenlockreceiver监听锁屏功能。分享给大家供大家参考，具体如下：

监听屏幕锁屏状态（注册接受者--执行业务--注销接受者）

public class applockservice extends service {
  private activitymanager am;
  private keyguardmanager keyguardmanager;
  private lockscreenreceiver receiver;
  @override
  public void oncreate() {
    // todo auto-generated method stub
    super.oncreate();
    am = (activitymanager) getsystemservice(context.activity_service);
    keyguardmanager = (keyguardmanager) getsystemservice(context.keyguard_service);
    //注册锁屏广播接收者
    intentfilter filter = new intentfilter();
    filter.addaction(intent.action_screen_off);
    receiver = new lockscreenreceiver();
    registerreceiver(receiver, filter);
    new thread(){
      public void run() {
        //一直在监听锁屏动作，一旦监听到，便执行操作
        while(true){
          boolean islockscreen = keyguardmanager.inkeyguardrestrictedinputmode();
          /**此处可作相应操作*/
        }
      };
    }.start();
  }
  private final class lockscreenreceiver extends broadcastreceiver{
    @override
    public void onreceive(context context, intent intent) {
      tempapplocks.clear();
    }
  }
  @override
  public void ondestroy() {
    super.ondestroy();
    //取消锁屏的广播监听
    unregisterreceiver(receiver);
  }
}
