Orientation of LinearLayout In Android

LinearLayout has attribute named Orientation which is used to set children of LinearLayout in vertical or horizontal manner.

Let us take Two Buttons and set them with Linear Layout in Android Layout.

1.) Set Horizontally Look below source code

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="schemas.android.com/apk/res/android"

    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal">

    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:text="Button" />

    <Button
        android:id="@+id/button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:text="Button" />
</LinearLayout>

Output of Above code will generate layout like below image.

2.) Set Vertically

Look below source code

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="schemas.android.com/apk/res/android"

    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical">

    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Button 1" />

    <Button
        android:id="@+id/button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Button 2" />
</LinearLayout>

Output of Above code will generate layout like below image.

As you can see that two button are set vertically. In LinearLayout orientation is set as vertical and two buttons are it’s children.

You can set all layouts like Linearlayout, Relativelayout, Framelayout, TableLayout, GridLayout etc. as child of each other.
