Android 底部导航栏的Tab选中不变色?

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。。

自己实现 Tab 标签的时候,要在切换时手动改变 View 的状态,才能让 View 显示对应状态的效果。你这里有没有把 那个标签 设置成 selected 的?
