主要功能
1.使用Button自定义底部Tab和Title
2.点击底部Tab后使用Fragment切换页面
3.主页使用ViewPager滚动显示新闻图片
4.自定义类处理Fragment重叠回退问题

二、对应底部Tab的XML布局文件
<FrameLayout
android:layout_width=“match_parent”
android:layout_height=“match_parent”
android:layout_weight=“1.0” >
<Button
android:id="@+id/button_state1"
android:layout_width=“match_parent”
android:layout_height=“match_parent”
android:background="@null"
android:button="@null"
android:drawableTop="@drawable/ic_message_selector"
android:gravity=“center”
android:singleLine=“true”
android:tag=“message”
android:text="@string/text_tab_message"
android:textColor="@color/text_service_color"
android:textSize=“14dp” />
<FrameLayout
android:layout_width=“match_parent”
android:layout_height=“match_parent”
android:layout_weight=“1.0” >
<Button
android:id="@+id/button_state2"
android:layout_width=“match_parent”
android:layout_height=“match_parent”
android:background="@null"
android:button="@null"
android:drawableTop="@drawable/ic_service_selector"
android:gravity=“center”
android:singleLine=“true”
android:tag=“service”
android:text="@string/text_tab_service"
android:textColor="@color/text_service_color"
android:textSize=“14dp” />
<FrameLayout
android:layout_width=“match_parent”
android:layout_height=“match_parent”
android:layout_weight=“1.0” >
<Button
android:id="@+id/button_state3"
android:layout_width=“match_parent”
android:layout_height=“match_parent”
android:background="@null"
android:button="@null"
android:drawableTop="@drawable/ic_profile_selector"
android:g
ravity=“center”
android:singleLine=“true”
android:tag=“personal”
android:text="@string/text_tab_profile"
android:textColor="@color/text_service_color"
android:textSize=“14dp” />
<FrameLayout
android:layout_width=“match_parent”
android:layout_height=“match_parent”
android:layout_weight=“1.0” >
<Button
android:id="@+id/button_state4"
android:layout_width=“match_parent”
android:layout_height=“match_parent”
android:background="@null"
android:button="@null"
android:drawableTop="@drawable/ic_setting_selector"
android:gravity=“center”
android:singleLine=“true”
android:tag=“settings”
android:text="@string/text_tab_setting"
android:textColor="@color/text_service_color"
android:textSize=“14dp” />
三、在启动的Acitvity界面中使用自定义的Tab类
<?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/layout_content"
android:layout_width=“match_parent”
android:layout_height=“match_parent”
android:layout_weight=“1.0” />
<app.ui.widget.TabView
android:id="@+id/view_tab"
android:layout_width=“match_parent”
android:layout_height="@dimen/header_height"
android:background="@color/tab_main_color" />
droid.com/apk/res/android"
android:layout_width=“match_parent”
android:layout_height=“match_parent”
android:orientation=“vertical” >
<FrameLayout
android:id="@+id/layout_content"
android:layout_width=“match_parent”
android:layout_height=“match_parent”
android:layout_weight=“1.0” />
<app.ui.widget.TabView
android:id="@+id/view_tab"
android:layout_width=“match_parent”
android:layout_height="@dimen/header_height"
android:background="@color/tab_main_color" />
