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);
}
}
