ViewPager+FragmentPageAdapter实现可

首先创建首页布局：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/activity_main"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:background="#C3C3C3"
    tools:context="news.huoren.com.themap.MainActivity">

    <include layout="@layout/top"/>

    <android.support.v4.view.ViewPager
        android:id="@+id/id_viewpager"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        ></android.support.v4.view.ViewPager>

    <include layout="@layout/bottom" />
</LinearLayout>

底部栏布局：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal"
    android:background="@drawable/bottom_bar"
    android:layout_width="match_parent"
    android:layout_height="55dp">

    <LinearLayout
        android:id="@+id/id_tab_weixin"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:gravity="center"
        android:orientation="vertical">

        <ImageButton
            android:id="@+id/id_tab_weixin_img"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:background="#000"
            android:clickable="false"
            android:src="@mipmap/tab_weixin_pressed"
            />
        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="微信"
            android:textColor="#ffffff"/>

    </LinearLayout>
    <LinearLayout
        android:id="@+id/id_tab_frd"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:gravity="center"
        android:orientation="vertical">

        <ImageButton
            android:id="@+id/id_tab_frd_img"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:background="#000"
            android:clickable="false"
            android:src="@mipmap/tab_find_frd_normal"
            />
        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="朋友"
            android:textColor="#ffffff"/>

    </LinearLayout>
    <LinearLayout
        android:id="@+id/id_tab_address"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:gravity="center"
        android:orientation="vertical">

        <ImageButton
            android:id="@+id/id_tab_address_img"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:background="#000"
            android:clickable="false"
            android:src="@mipmap/tab_address_normal"
            />
        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="通讯录"
            android:textColor="#ffffff"/>

    </LinearLayout>
    <LinearLayout
        android:id="@+id/id_tab_setting"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:gravity="center"
        android:orientation="vertical">

        <ImageButton
            android:id="@+id/id_tab_setting_img"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:background="#000"
            android:clickable="false"
