Nested LinearLayout shows only the first View

I have seen some question the can be similar to this. However, those scenario were different and some are not for beginners.
So I just started Android recently. Please understand that I'm new to *.xml. Anyway, my concern is regarding the nested LinearLayout that only shows the first View.

<LinearLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context=".MainActivity" >

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

        <TextView
            android:layout_gravity="center"
            android:layout_weight="1"
            android:layout_height="wrap_content"
            android:layout_width="0dp"
            android:textSize="20sp"
            android:text="@string/app_title">
        </TextView>

    </LinearLayout>

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

        <Button 
            android:layout_gravity="center"
            android:layout_height="wrap_content"
            android:layout_width="wrap_content"
            android:text="@string/button_ok"
            android:onClick="changeMessage">
        </Button>

        <TextView
            android:layout_gravity="center"
            android:textSize="20sp"
            android:id="@+id/this_text"
            android:layout_height="wrap_content"
            android:layout_width="wrap_content"
            android:text="@string/sample_text">
        </TextView>

    </LinearLayout>

</LinearLayout>

Here's the XML so far. With this code, only the first TextView is only showing.

change the layout as below

<LinearLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context=".MainActivity" >
<LinearLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_height="match_parent"
    android:layout_width="wrap_content"
    android:orientation="horizontal">

    <TextView
        android:layout_gravity="center"
        android:layout_weight="1"
        android:layout_height="wrap_content"
        android:layout_width="0dp"
        android:textSize="20sp"
        android:text="@string/app_title">
    </TextView>

</LinearLayout>

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

    <Button 
        android:layout_gravity="center"
        android:layout_height="wrap_content"
        android:layout_width="wrap_content"
        android:text="@string/button_ok"
        android:onClick="changeMessage">
    </Button>

    <TextView
        android:layout_gravity="center"
        android:textSize="20sp"
        android:id="@+id/this_text"
        android:layout_height="wrap_content"
        android:layout_width="wrap_content"
        android:text="@string/sample_text">
    </TextView>

</LinearLayout>

Your inner Layouts are matching with the Parent layout so only first layout will be shown.

because you have given first LinearLayout width and height to matchparent

Change its height to wrapcontent

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

    <TextView
        android:layout_gravity="center"
        android:layout_weight="1"
        android:layout_height="wrap_content"
        android:layout_width="0dp"
        android:textSize="20sp"
        android:text="@string/app_title">
    </TextView>

</LinearLayout>

// other layouts

android:layout_height="match_parent" the height of the nested LinearLayout should be wrap_content instead of match_parent
