实现监听器

ScreenListener screenListener = new ScreenListener( MainActivity.this ) ;screenListener.begin(new ScreenListener.ScreenStateListener() {    @OverrIDe    public voID onScreenOn() {        //屏幕打开了    }    @OverrIDe    public voID onScreenOff() {        //屏幕关闭了    }    @OverrIDe    public voID onUserPresent() {        //解锁了    }});
