Question

我正在编写一个基于sip的呼叫应用程序。当有来电时，它的相应活动被触发并显示在锁定屏幕下方。但是用户无法了解通话...锁定屏幕出现一段时间并且屏幕关闭..即使通话仍然响铃...铃声在整个持续时间内都处于活动状态但是屏幕没有不显示来电UI。我需要找到一种方法来显示相应的用户界面，并在整个来电期间保持屏幕显示...

对于在整个来电期间保持屏幕开启的部分我正在使用唤醒锁......但我无法摆脱锁定屏幕......

我进行了研究，发现可以使用KeygaurdManager或WindowManager.LayoutParams以及FLAG_KEEP_SCREEN_ON，FLAG_DISMISS_KEYGAURD，FLAG_SHOW_WHEN_LOCKED和FLAG_TURN_SCREEN_ON等适当的标记来解锁电话...但是这些在我的情况下不起作用...我在下面的一个链接中读到，当手机密码/模式锁定时无法解锁手机......这就是为什么我无法解决的问题显示我想要的UI？如何接听来电？请建议我一些解决方案

Answer 1

对我而言，以下代码运作良好。

@Override
protected void onCreate() {
    KeyguardManager km = (KeyguardManager) getSystemService(Context.KEYGUARD_SERVICE);
    keyguard = km.newKeyguardLock("MyApp");
}
//when we need to unlock screen
@Override
protected void onResume() {
    keyguard.disableKeyguard();
}
@Override
protected void onPause() {
    keyguard.enableKeyguard();
}

请记住同时添加权限

<uses-permission android:name="android.permission.DISABLE_KEYGUARD" />

FLAG_SHOW_WHEN_LOCKED适用于大多数手机。活动必须是不透明的（不是对话框）。您可能还需要FLAG_TURN_SCREEN_ON和FLAG_KEEP_SCREEN_ON

但是，在运行4.0.3的Galaxy Note上，它目前不适用于我。还不确定为什么......
