无法单击FrameLayout内的LinearLayout中的按钮

Question

我正在构建一个测验应用。在初始测验屏幕上，我想要一个指令屏幕，告诉用户点击任何地方继续下一个问题。为了达到这个目的，我在FrameLayout内填了两个LinearLayout。第一个LinearLayout包含测验屏幕。第二个LinearLayout包含带有按钮的指令屏幕（将此按钮称为Ok Button ）。我想在用户点击此Ok Button时关闭指令屏幕。问题是我无法点击Ok Button。当用户点击它时，它没有显示任何物理反应（如按钮按下）等，它都不会触发其onClick方法。

我还为第二个android:clickable="true"设置了LinearLayout，以便它响应用户点击而不是将其传递到第一个LinearLayout

我无法理解我的代码有什么问题。任何人都可以帮我解决这个问题。我坚持这个真正的坏事。

这是我的xml （按钮ID为：got_it_button ）：
