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); } }
