Android Tab Widget Won't Fill The Width Of The Screen

I'm completely new to Android dev and XML. What I'm trying to do is create 4 tabs at the bottom of the screen, and for the tabs to fill the width of the screen. I have been able to

Solution 1:

Your problem is that TabHost is derived from FrameLayout, which, as the description states, is only for holding one element, and you're stuffing it with two: a TabWidget and a FrameLayout.

Try this: (note how I also removed FrameLayout - trying to fill in tabs like that is a bad idea)

<?xml version="1.0" encoding="utf-8"?><!-- Dublin Bus App --><TabHostxmlns:android="http://schemas.android.com/apk/res/android"android:orientation="vertical"android:layout_width="fill_parent"android:layout_height="fill_parent"android:id="@+id/tab_host"><LinearLayoutandroid:orientation="vertical"android:layout_width="fill_parent"android:layout_height="fill_parent"><TabWidgetandroid:id="@android:id/tabs"android:layout_width="fill_parent"android:layout_height="wrap_content"android:layout_gravity="bottom"/><FrameLayoutandroid:id="@android:id/tabcontent"android:layout_width="fill_parent"android:layout_height="fill_parent"android:padding="5dp" /></LinearLayout></TabHost>

Then follow the HelloTabWidget tutorial to fill the tabs with content.

Solution 2:

Try android:width="match_parent"
