<?xml version="1.0" encoding="utf-8"?>

</LinearLayout>

whatever number child views in LinearLayout, tab indicator only use the first child
and height in LinearLayout don't work, why?
and width, height in TextView don't work too, just work with specific height, ex: 60dip

How's TabSpec.setIndicator work?

padding work with LinearLayout, chung' to? la` tab indicator khong co ignore parent layout
