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>
下面是代码注释全自己看

创建一个Fragment "TabFragment"
