android - overdraw layout allows touch through LinearLayout

问题

in the following UI I have this below drabable overlaying the entire screen. The LinearLayout is transparent and allows controls below it to be clickable or touchable. Basically I can scroll a list below this LinearLayout as well as click controls. How do I disable that?

See attached example.

Thank you

<RelativeLayout
     xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/rlExtNavbar" 
    android:orientation="vertical"
    android:layout_width="match_parent" 
    android:layout_height="match_parent"
    android:gravity="fill_vertical"
    android:layout_gravity="fill_vertical"
    android:background="@color/transparent" xmlns:tools="http://schemas.android.com/tools" tools:ignore="Overdraw">
    <RelativeLayout
        android:id="@+id/expandedNavbarLayout" 
        android:orientation="vertical"
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content" >
    </RelativeLayout>
    <LinearLayout
        android:id="@+id/transparentLayout" 
        android:orientation="vertical"
        android:layout_width="match_parent" 
        android:layout_height="wrap_content"
        android:layout_below="@id/expandedNavbarLayout"
        android:focusableInTouchMode="false"
        android:focusable="false"
        android:background="@color/fulltransparent">
    </LinearLayout>

</RelativeLayout>

Just setting the android:clickable="true" property for the LinearLayout in the XML will prevent the clicks going through -- no need for a click listener.

Assigned a click to Linear Layout and that solved it. Honestly it should not be working like this to begin with but that solved the problem. The click is empty.

What worked for me was to put the LinearLayout before the inner RelativeLayout in the xml.
