自定义锁屏延迟当唤醒

问题描述

我试图使自定义锁屏应用程序，但我不知道如果我要了解它的正确途径。我有一个广播接收器监听当屏幕开启并开始我的锁屏的活动。该接收器注册一个服务，这也禁用默认锁屏内。

现在的问题是，有当屏幕开启和锁定屏幕活动显示了之间稍有延迟。我怎么会去这样做，以便它显示出来的时候了？

我的code的服务：

  @覆盖
公共无效的onCreate（）{
    super.onCreate（）;
    IntentFilter的过滤器=新的IntentFilter（Intent.ACTION_SCREEN_ON）;
    filter.addAction（Intent.ACTION_SCREEN_OFF）;
    BroadcastReceiver的powerReceiver =新PowerReceiver（）;
    registerReceiver（powerReceiver，过滤器）;
}

@覆盖
公众诠释onStartCommand（意向意图，诠释标志，诠释startId）{

    KeyguardManager keyguardManager =（KeyguardManager）getSystemService（Service.KEYGUARD_SERVICE）;
    KeyguardLock锁= keyguardManager.newKeyguardLock（KEYGUARD_SERVICE）;
    lock.disableKeyguard（）;

    返回Service.START_STICKY;
}

@覆盖
公众的IBinder onBind（意向意图）{
    返回null;
}
 

和接收器：

  @覆盖
公共无效的onReceive（上下文的背景下，意图意图）{
    如果（intent.getAction（）。等于（Intent.ACTION_SCREEN_ON））{
        意图showScreen =新的意图（背景下，LockScreen.class）;
        showScreen.addFlags（Intent.FLAG_ACTIVITY_NEW_TASK）;
        context.startActivity（showScreen）;


    }

}
 

解决方案

打开你的应用程序到主屏幕更换应用程序，而当用户成功解除自定义锁屏，你可以带他们到默认主页的应用程序。

I'm trying to make a custom lock screen app, but I'm not sure if I'm going about it the right way. I have a broadcast receiver that listens to when the screen is turned on and starts my lock screen activity. This receiver is registered inside a service, which also disables the default lock screen.

The problem is, there is a slight delay between when the screen is turned on and the lock screen activity shows up. How would I go about doing it so that it shows up right away?

My code for the service:

@Override
public void onCreate() {
    super.onCreate();
    IntentFilter filter = new IntentFilter(Intent.ACTION_SCREEN_ON);
    filter.addAction(Intent.ACTION_SCREEN_OFF);
    BroadcastReceiver powerReceiver = new PowerReceiver();
    registerReceiver(powerReceiver, filter);
}

@Override
public int onStartCommand(Intent intent, int flags, int startId) {

    KeyguardManager keyguardManager = (KeyguardManager)getSystemService(Service.KEYGUARD_SERVICE);
    KeyguardLock lock = keyguardManager.newKeyguardLock(KEYGUARD_SERVICE);
    lock.disableKeyguard();

    return Service.START_STICKY;
}

@Override
public IBinder onBind(Intent intent) {
    return null;
}

and the receiver:

@Override
public void onReceive(Context context, Intent intent) {
    if (intent.getAction().equals(Intent.ACTION_SCREEN_ON)) {
        Intent showScreen = new Intent(context, LockScreen.class);
        showScreen.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        context.startActivity(showScreen);


    }

}

解决方案

Turn your app into a home screen replacement app and when the user successfully unlocks the custom lock screen you can take them to the default home app.
