Hello How I can create bottom TabWidget in FragmentTabHost ? My xml looks line this:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<FrameLayout
android:id="@android:id/tabcontent"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1" >
<FrameLayout
android:id="@ id/realtabcontent"
android:layout_width="match_parent"
android:layout_height="fill_parent" />
</FrameLayout>
<TabWidget
android:id="@android:id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="0"
android:orientation="horizontal"
android:tabStripEnabled="false" />
</LinearLayout>
But my TabWidget is still at the top.
I came up with this solution after six hrs effort on it..
a solution is
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<FrameLayout
android:id="@ id/realtabcontent"
android:layout_width="match_parent"
android:layout_height="0dip"
android:layout_weight="1" />
This a google 's bug, google say
/** This is a helper class that implements a generic mechanism for
* associating fragments with the tabs in a tab host. It relies on a trick.
* Normally a tab host has a simple API for supplying a View or Intent that
* each tab will show.This is not sufficient for switching between
* fragments. So instead we make the content part of the tab host 0dp high
* (it is not shown) and the TabManager supplies its own dummy view to show
* as the tab content. It listens to changes in tabs, and takes care of
* switch to the correct fragment shown in a separate content area whenever
* the selected tab changes.

Sedcond solution,
可以说得再宽泛点，你想在layout布局文件上改变它的任意一点布局，你会发现。。。都是徒劳的。——因为Google源码里面存在bug，bug在于：android.support.v4.app.FragmentTabHost.java源码里有一段（155行到177行）的功能是判断如果用户没有设置关于FragmentTabHost的布局文件，就采用默认布局（即TabWidget在最上面），但是这里这个判断的函数永远都是null，就是说它只会采用默认布局，这里是个Bug。
解决办法就是：
