<?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:background="#eee"    android:orientation="vertical" >    <include layout="@layout/main_head"/>    <com.viewpagerindicator.TabPageIndicator        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:id="@+id/vpi_tab"        android:background="#C0D0E0">    </com.viewpagerindicator.TabPageIndicator>    <android.support.v4.view.ViewPager        android:layout_width="match_parent"        android:layout_height="0dp"        android:layout_weight="1"        android:id="@+id/vp_content"/></LinearLayout>
