Android Studio-按钮顶部的相对布局具有透明背景

Question

I am trying to create a RelativeLayout on the top of another containing buttons in order to hide the ones below.

I have set a black background to the top RelativeLayout however, the layout is till transparent showing the objects underneath. Also The buttons behind the top relative layout are still clickable.

My question is how can I use a RelativeLayout in order to hide another one containing object underneath? The top relative layout should be NOT transparent and the buttons underneath not clickable.

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <RelativeLayout
        android:visibility="gone"
        android:id="@+id/buttons"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <!-- Your buttons go here -->

    </RelativeLayout>

    <RelativeLayout
        android:id="@+id/prompt"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <!-- your prompt -->

    </RelativeLayout>
</FrameLayout>

and when you're done with your prompt relative layout, then from your activity say something like this:

View prompt = findeViewById(R.id.prompt);
prompt.setVisibility(View.GONE);

and then visible your button layout

View buttonLayout = findeViewById(R.id.buttons);
buttonLayout.setVisibility(View.VISIBLE);
