可以看到切换不同的Fragment的时候，下面木有选中变色。
这是主界面代码，我自定义了组合控件：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:local="http://schemas.android.com/apk/res/com.mh.wxhelper" 
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >
    <FrameLayout
        android:id="@+id/fl_main_real_content"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1" />
    <View
        android:layout_width="match_parent"
        android:layout_height="1dp"
        android:background="@color/divider_color" />
    <LinearLayout
        android:id="@+id/ll_main_tab_container"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@color/gray_bg"
        android:orientation="horizontal" >
        <com.mh.wxhelper.view.TabItemView
            android:id="@+id/ttv_main_associatorQuery"
            local:ttv_image="@drawable/community_tab_item_bg"
            local:ttv_text="@string/associator_query"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1" >
        </com.mh.wxhelper.view.TabItemView>
        <com.mh.wxhelper.view.TabItemView
            android:id="@+id/ttv_main_activtiy"
            local:ttv_image="@drawable/community_tab_item_bg"
            local:ttv_text="@string/activity"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1" >
        </com.mh.wxhelper.view.TabItemView>
        <com.mh.wxhelper.view.TabItemView
            android:id="@+id/ttv_main_community"
            local:ttv_image="@drawable/community_tab_item_bg"
            local:ttv_text="@string/community"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1" >
        </com.mh.wxhelper.view.TabItemView>
        <com.mh.wxhelper.view.TabItemView
            android:id="@+id/ttv_main_me"
            local:ttv_image="@drawable/me_tab_item_bg"
            local:ttv_text="@string/me"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1" >
        </com.mh.wxhelper.view.TabItemView>
    </LinearLayout>
</LinearLayout>

这是自定义组合控件的布局文件：

<?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="wrap_content"
    android:gravity="center"
    android:orientation="vertical"
    android:paddingBottom="@dimen/tab_bar_item_top_bottom_padding"
    android:paddingTop="@dimen/tab_bar_item_top_bottom_padding" >
    <ImageView
        android:id="@+id/iv_tab_item_icon"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:contentDescription="@string/app_name" >
    </ImageView>
    <TextView
        android:id="@+id/tv_tab_item_text"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textColor="@drawable/tab_bar_item_text_color"
        android:textSize="@dimen/tab_bar_text_size" >
    </TextView>
</LinearLayout>

文字颜色tab_bar_item_text_color:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_focused="true" android:color="@color/tab_bar_item_text_selected_color"/>
    <item android:state_selected="true" android:color="@color/tab_bar_item_text_selected_color"/>
    <item android:state_pressed="true" android:color="@color/tab_bar_item_text_selected_color"/>
    <item android:color="@color/tab_bar_item_text_normal_color"/></selector>

image也是选中变色的：
community_tab_item_bg.xml：

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_focused="true" android:drawable="@drawable/community_selected"/>
    <item android:state_selected="true" android:drawable="@drawable/community_selected"/>
    <item android:state_pressed="true" android:drawable="@drawable/community_selected"/>
    <item android:drawable="@drawable/community"/></selector>

是LinearLayout的缘故吗？我还想做冒泡功能。。
