layout_weight attribute in <include> tag

Question

I'm trying to reuse some layout components in android application using <include> tag. I've got different port and land layouts:

1. Port:

   <LinearLayout a:layout_weight="1" a:layout_width="match_parent" a:layout_height="0dp">
   
       <include layout="@layout/calc_equals_button" a:layout_weight="4"/>
       <include layout="@layout/calc_display"/>
   
   </LinearLayout>
   

2. Land:

   <LinearLayout a:layout_weight="1" a:layout_width="match_parent" a:layout_height="0dp">
   
       <include layout="@layout/calc_equals_button"/>
       <include layout="@layout/calc_display"/>
   
   </LinearLayout>
   

Main difference is a:layout_weight="4", so i want my calc_equals_button component to be smaller in port orientation.

The thing is if i try to embed calc_equals_button component directly everything works OK, e.g.:

<LinearLayout a:layout_weight="1" a:layout_width="match_parent" a:layout_height="0dp">
        <DirectionDragButton
                xmlns:a="http://schemas.android.com/apk/res/android"
                a:id="@+id/equalsButton"
                a:text="="
                a:layout_width="match_parent"
                a:layout_height="match_parent"
                a:layout_weight="4"
                style="@style/control_button_style"
                a:onClick="numericButtonClickHandler"/>

        <include layout="@layout/calc_display"/>

    </LinearLayout>

otherwise - NOT.

Here is sample of calc_equals_button.xml:

<DirectionDragButton
    xmlns:a="http://schemas.android.com/apk/res/android"
    a:id="@+id/equalsButton"
    a:text="="
    a:layout_width="match_parent"
    a:layout_height="match_parent"
    style="@style/control_button_style"
    a:onClick="numericButtonClickHandler"/>

Answer 1

A current limitation of is that you must specify layout_width and layout_height for other layout_* attributes to be applied.
