android - 标准调用屏幕上的 Activity 窗口 - 启用按钮

Question

我想在通话屏幕 Activity 中添加一个小窗口(弹出窗口)。 Google 语音 和 worldcallplaceandtime在通话期间都添加了相同的窗口。

问题是当我在屏幕顶部打开一个新 Activity 时，其余按钮被禁用(结束通话、静音等)。单击结束通话按钮的唯一选项仅在我关闭添加的新 Activity 时出现。

谁能告诉我如何在屏幕上添加一个小窗口并且仍然能够使用调用标准按钮？

这是我用来在调用屏幕上添加覆盖按钮而不禁用按钮的代码。 我希望它能帮助..

    public void addInvitePopup(final String number){
