How to set height of one layout to another layout?

Question

I have one parent LinearLayout and inside it I have two child LinearLayout. I have 4 TextView in 1st child layout and 2 TextView in 2nd child layout. Parent layout has property android:layout_height="wrap_content as well as child layout too.

I want to set height of 1st child layout to 2nd child layout because 1st child layout has 4 textbox and 2nd child layout has to textbox.

I just want to adjust the height of 2nd child layout. I am putting my code below.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:weightSum="1"
    android:orientation="horizontal"
    android:layout_alignParentTop="true">

<LinearLayout
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:layout_weight=".8"
    android:orientation="vertical">

    <TextView
        android:id="@+id/lblBooking_Code"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

    <TextView
        android:id="@+id/lblSession"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

    <TextView
        android:id="@+id/lblCustomer"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"/>

    <TextView
        android:id="@+id/lblAddress"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"/>

    <TextView
        android:id="@+id/lblMobile"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"/>

</LinearLayout>

<LinearLayout
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:layout_weight=".1"
    android:orientation="vertical">

    <TextView
        android:id="@+id/lblBooking_Gross_Amt"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

    <TextView
        android:id="@+id/lblBooking_PayAmt"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"/>

    <TextView
        android:id="@+id/lblBooking_Balance"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

</LinearLayout>

</LinearLayout>

Answer 1

Make the height of 2nd child layout "match_parent"

Answer 2

Making the height of 2nd child layout "match_parent" and implementing "weightSum=3" I achieved my requirement.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:weightSum="1"
    android:orientation="horizontal"
    android:layout_alignParentTop="true">

<LinearLayout
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:layout_weight=".8"
    android:orientation="vertical">

    <TextView
        android:id="@+id/lblBooking_Code"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

    <TextView
        android:id="@+id/lblSession"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

    <TextView
        android:id="@+id/lblCustomer"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"/>

    <TextView
        android:id="@+id/lblAddress"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"/>

    <TextView
        android:id="@+id/lblMobile"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"/>

</LinearLayout>

<LinearLayout
    android:layout_width="0dp"
    android:layout_height="match_parent"
    android:layout_weight=".1"
    android:weightSum="3"
    android:orientation="vertical">

    <TextView
        android:id="@+id/lblBooking_Gross_Amt"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1" />

    <TextView
        android:id="@+id/lblBooking_PayAmt"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"/>

    <TextView
        android:id="@+id/lblBooking_Balance"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1" />
