使用ViewpagerIndicator与viewpager实现tab标签

下载地址：https://github.com/JakeWharton/ViewPagerIndicator

问题：1：新建的 项目和viewpagerindicator都有android-support-v4.jar。有可能版本不一样，而且不能有两个。不项目的android-support-v4.jar删除。

           2:布局小问题。因为加了头部布局覆盖了，导致fragment不显示。

<?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:orientation="horizontal" >


    <ImageView
        android:id="@+id/image_app"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginLeft="10dp"
        android:layout_marginTop="10dp"
        android:src="@drawable/apporderform" />


    <TextView
        android:id="@+id/home_text"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_marginTop="10dp"
        android:layout_weight="1"
        android:gravity="center"
        android:text="@string/head" />


    <ImageView
        android:id="@+id/image_add"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginRight="10dp"
        android:layout_marginTop="10dp"
        android:src="@drawable/add_num" />


    <ImageView
        android:id="@+id/image_search"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginRight="10dp"
        android:layout_marginTop="10dp"
        android:src="@drawable/appsearch" />


</LinearLayout>

显示效果：

主布局：<?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" >


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


  <com.viewpagerindicator.TabPageIndicator
        android:id="@+id/tab_pageindicator"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" >
    </com.viewpagerindicator.TabPageIndicator> 


    <android.support.v4.view.ViewPager
        android:id="@+id/tab_viewpager"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
         />


</LinearLayout>
