如何在同时来电/关状态屏幕分辨？ [英] How to distinguish the screen on/off status while incoming call?

问题描述

我的应用程序使用 TelephonyManager.ACTION_PHONE_STATE_CHANGED 的一些行动。但我想不同的操作，而手机响了起来，当用户是present（屏幕是打开的）和不同的操作，当用户没有present（屏幕是关闭）。我试过 isScreenOn（）方法只在的onReceive 的开始（因为当屏幕关闭，并有来电，屏幕一直不亮一小会儿）。然而，没有运气 - 有时它的工作原理，有时没有。广播是异步的屏幕状态...

My app uses the TelephonyManager.ACTION_PHONE_STATE_CHANGED for some actions. But I want a different action while the phone rang when the user was present (screen was on) and different action when the user was not present (screen was off). I tried the isScreenOn() method just in the beginning of onReceive (because when screen is off and there is incoming call, the screen stays off for a short while). No luck however - sometimes it works, sometimes not. The broadcast is asynchronous with the screen state...

public void onReceive(Context context, Intent intent) {
    pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE);
    Boolean screenOn = pm.isScreenOn();
    Log.w(TAG, "Screen on is " + screenOn.toString());

我

如何改变我的code真正确定，如果手机在睡觉时，电话来了吗？

How could I change my code to truly determine if the phone was sleeping when the call arrived?

推荐答案

好吧，我得到了满足我的答案：

Ok, I got the answer which satisfies me:

public void onReceive(Context context, Intent intent) {
    KeyguardManager kg = (KeyguardManager) context.getSystemService(Context.KEYGUARD_SERVICE);
    Boolean screenBlocked = !kg.inKeyguardRestrictedInputMode();
    Log.w(TAG, "Screen lock is " + screenBlocked.toString());

如果屏幕被锁定这样的解决方案提供了信息。而且，在我而言，这是不够 - 当屏幕上的来电时被锁定 - 这意味着没有用户

Such solution gives information if the screen is locked. And, in my case, it is enough - when screen is locked during the incoming call - it means that there was no user.
