TabHost底部导航知识回顾之模仿微信导航

以前用Fragment模仿过微信底部导航 不过最近一个简单的项目准备用TabHost来做底部导航 所以回顾了一下TabHost的知识，做了一个简单的用TabHost来模仿微信导航的demo   因为图片的都是用以前的图片东西 需要的可以看Fragment之模仿微信界面 所以只贴出关键代码 效果如下图：

<?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="match_parent"
    android:layout_height="match_parent" >

    <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="0.0dip"
            android:layout_weight="1.0" >
        </FrameLayout>

        <TabWidget
            android:id="@android:id/tabs"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:visibility="gone" >
        </TabWidget>

        <RadioGroup
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_gravity="bottom"
            android:background="@android:color/black"
            android:orientation="horizontal" >

            <RadioButton
                android:id="@+id/talk"
                style="@style/rbt_bottom"
                android:drawableTop="@drawable/take_bottom"
                android:text="@string/talk" />

            <RadioButton
                android:id="@+id/address"
                style="@style/rbt_bottom"
                android:drawableTop="@drawable/adrress_bottom"
                android:text="@string/address" />

            <RadioButton
                android:id="@+id/find"
                style="@style/rbt_bottom"
                android:drawableTop="@drawable/find_bottom"
                android:text="@string/find" />

            <RadioButton
                android:id="@+id/me"
                style="@style/rbt_bottom"
                android:drawableTop="@drawable/me_bottom"
                android:text="@string/me" />
        </RadioGroup>
    </LinearLayout>
