简单的界面开始
rawerLayout是Library包中实现了侧滑菜单效果的控件，drawerLayout分为侧边菜单和主内容区两部分，侧边菜单可以根据手势展开与隐藏（drawerLayout自身特性），
一定要导入包
布局
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/draw"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
>
<android.support.design.widget.TabLayout
android:layout_width="match_parent"
android:layout_height="45dp"
app:tabMode="scrollable"
android:id="@+id/tab_layout"
>
</android.support.design.widget.TabLayout>
<android.support.v4.view.ViewPager
android:id="@+id/viewPager"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="@id/tab_layout"
>
</android.support.v4.view.ViewPager>
</LinearLayout>
<ListView
android:id="@+id/left_lv"
android:layout_width="240sp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:choiceMode="singleChoice"
android:divider="#191515"
android:dividerHeight="1dp"
android:background="#fff"
/>
</android.support.v4.widget.DrawerLayout>
fragment.xml 里面写一个pullToRefreshListView
<?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">
<com.handmark.pulltorefresh.library.PullToRefreshListView
xmlns:ptr="http://schemas.android.com/apk/res-auto"
android:id="@+id/pull_refresh_list"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:cacheColorHint="#000000"
android:divider="#19000000"
android:dividerHeight="4dp"
android:fadingEdge="none"
android:fastScrollEnabled="false"
android:footerDividersEnabled="false"
android:headerDividersEnabled="false"
android:smoothScrollbar="true"
ptr:ptrAnimationStyle="rotate"
ptr:ptrHeaderTextColor="#ffffff"
ptr:ptrHeaderSubTextColor="#00ffff"
ptr:ptrHeaderBackground="@null"
ptr:ptrDrawable="@mipmap/ic_launcher"/>
</LinearLayout>
