LinearLayout

suggest change

The LinearLayout is a ViewGroup that arranges its children in a single column or a single row. The orientation can be set by calling the method setOrientation() or using the xml attribute android:orientation.

Vertical orientation : android:orientation="vertical"

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

    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="@string/app_name" />

    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="@android:string/cancel" />

</LinearLayout>

Here is a screenshot how this will look like:

Horizontal orientation : android:orientation="horizontal"

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

    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="@string/app_name" />

    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="@android:string/cancel" />

</LinearLayout>

The LinearLayout also supports assigning a weight to individual children with the android:layout_weight attribute.
