LinearLayout in Android (Vertical, XML)

Public on December 30, 2008
Reading this, you probably have a clue that LinearLayout lays out object linearly and can only have a vertical and horizontal layout, no diagonal layout.

Here is an example of a vertical LinearLayout:
(update: horizontal LinearLayout here)
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout android:id="@+id/LinearLayout01"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
>
<Button android:id="@+id/RecordBtn"
android:text="Record"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />

<Button android:id="@+id/PlayBtn"
android:text="Play"
android:layout_height="wrap_content"
android:gravity="right"
android:layout_width="fill_parent" />

<Button android:id="@+id/StopBtn"
android:text="Stop"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:gravity="left" />

<Button android:id="@+id/PauseBtn"
android:text="Pause"
android:layout_height="wrap_content"
android:layout_width="fill_parent" />
</LinearLayout>

Quick Explanation:
There would be 4 buttons here, Record, Play, Stop and Pause, each one have its id and a wrap_content height, 3 of the buttons have fill_parent which mean fill up all spaces their width, gravity is text-align in css. See the picture below to better understand.
