来电时如何区分屏幕开关状态？

我的应用使用 TelephonyManager.ACTION_PHONE_STATE_CHANGED 执行某些操作。但我想要在用户在场（屏幕打开）时电话响起时执行不同的操作，在用户不在场（屏幕关闭）时执行不同的操作。我在 onReceive 的开头尝试了 isScreenOn() 方法（因为当屏幕关闭并且有来电时，屏幕会保持关闭一小会儿）。然而运气不佳——有时有效，有时无效。广播与屏幕状态异步...

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());

我如何更改代码以真正确定电话到达时手机是否正在睡眠？

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());

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

好的，我得到了令我满意的答案：

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，这样的解决方案会提供信息。而且，就我而言，这已经足够了 - 当来电期间屏幕被锁定时 - 这意味着没有用户。

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());

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.
