This little tip will show you how to align your TabHost at the bottom of the screen in your Android app, like this:

I assume you know how to use the TabHost the usual way (I might write a tutorial on that later).

Say you are using your TabHost the following way:

<?xml version="1.0" encoding="utf-8"?>
<TabHost
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@android:id/tabhost"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
    <LinearLayout
        android:orientation="vertical"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:padding="5dp">
        <TabWidget
            android:id="@android:id/tabs"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content" />
        <FrameLayout
            android:id="@android:id/tabcontent"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:padding="5dp" />
    </LinearLayout>
</TabHost>

You then have the tabs on top, like this:

But if you switch out the LinearLayout with a RelativeLayout, like this:

<?xml version="1.0" encoding="utf-8"?>
<TabHost
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@android:id/tabhost"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
    <RelativeLayout
        android:layout_height="fill_parent"
        android:layout_width="fill_parent">
        <TabWidget
            android:id="@android:id/tabs"
            android:layout_alignParentBottom="true"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content" />
        <FrameLayout
            android:id="@android:id/tabcontent"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:padding="5dp" />
    </RelativeLayout>
</TabHost>

Then you can specify the alignment of your TabWidget (on line 12), to align it at the bottom:

android:layout_alignParentBottom=”true”

And you get the result as seen in the first image!

Edit April 25:

As pointed out in the comments, there was an error in the layout.
Paul J. Ghosh made a comment on this, with working xml layout, which unfortunately got filtered out by the spam filter.

Thank you.
