在Fragment中，使用CoordinatorLayout+TabLayout布局，會遇到recyclerview 給遮擋的問題，修改完成，效果圖如下：

         一.先上布局代碼

<?xml version="1.0" encoding="utf-8"?><android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:app="http://schemas.android.com/apk/res-auto"    android:background="@color/white"    android:orientation="vertical"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:id="@+id/sl_layout"    >    <android.support.design.widget.AppBarLayout        android:id="@id/id_stickynavlayout_topview"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:theme="@style/APPTheme.AppBarOverlay"        app:elevation="0.5dp"        android:fitsSystemWindows="true">        <android.support.v7.widget.Toolbar            xmlns:app="http://schemas.android.com/apk/res-auto"            xmlns:tools="http://schemas.android.com/tools"            android:id="@+id/toolbar"            android:layout_width="match_parent"            android:layout_height="@dimen/title_bar"            android:minHeight="@dimen/title_bar"            android:theme="@style/MyToolbar"            app:titleTextAppearance="@style/ToolbarTextAppearance.Title"            app:layout_scrollFlags="scroll|enterAlways"            >            <TextView                android:textColor="@color/white"                android:id="@+id/textView_toolbar_title"                android:layout_width="wrap_content"                android:layout_height="wrap_content"                android:layout_gravity="center"                android:ellipsize="end"                android:singleLine="true"                android:textSize="20sp"                tools:text="首頁" />        </android.support.v7.widget.Toolbar>        <RelativeLayout            android:background="@color/white"            android:padding="12dp"            android:layout_width="match_parent"            android:layout_height="wrap_content"            app:layout_scrollFlags="scroll|enterAlways"            >            <ImageView                android:id="@+id/iv_head"                android:src="@mipmap/zh_touxiang"                android:layout_width="80dp"                android:layout_height="80dp" />            <TextView                android:textColor="@color/text_title"                android:paddingLeft="12dp"                android:layout_centerVertical="true"                android:layout_toRightOf="@id/iv_head"                android:text="等級 : 總代理"                android:layout_width="wrap_content"                android:layout_height="wrap_content" />            <TextView                android:textColor="@color/cl_default"                android:gravity="center"                android:layout_centerVertical="true"                android:layout_alignParentRight="true"                android:text="我要升級"                android:layout_width="80dp"                android:layout_height="30dp" />        </RelativeLayout>        <android.support.design.widget.TabLayout            android:id="@id/id_stickynavlayout_indicator"            android:layout_width="match_parent"            android:layout_height="wrap_content"            android:background="#ffffff"            app:tabGravity="fill"            app:tabMode="fixed"            app:tabTextColor="#A2A2A2"            app:tabIndicatorColor="@color/white"            app:tabSelectedTextColor="#000000"            >        </android.support.design.widget.TabLayout>    </android.support.design.widget.AppBarLayout>    <LinearLayout        android:layout_width="match_parent"        android:layout_height="match_parent"        android:orientation="vertical"        android:scrollbars="none"        app:layout_behavior="@string/appbar_scrolling_view_behavior">    <!--appbar_scrolling_view_behavior-->    <android.support.v4.view.ViewPager        android:background="#fff"        android:id="@id/id_stickynavlayout_viewpager"        android:layout_width="match_parent"        android:layout_height="match_parent"        >    </android.support.v4.view.ViewPager>    </LinearLayout></android.support.design.widget.CoordinatorLayout>
  本項目用的recylerview是封裝了上拉加載和下拉刷新的SuperRecyclerView,這樣會造成列表會給底部的tab遮擋，解決方案如下:
  1.在tablyout的fragment中,加入設置recylerview的邊距代碼
 
 LinearLayout.LayoutParams params = (LinearLayout.LayoutParams) ry_PRimary.getLayoutParams();        params.setMargins(0,0,0, DensityUtils.dp2px(mContext,60));        ry_primary.setLayoutParams(params);
 這樣會讓recylerview的item顯示正常,第二次切換的時候，在重新把邊距設置為0,就不會出現，recylerview距離底部有距離的情況。
 
2.第二種方式比較簡單，直接給SuperRecyclerView添加下拉刷新，就能解決item給tab遮擋的問題
 ry_primary.setRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {            @Override            public void onRefresh() {                lists.clear();                for (int i=0; i < 10; i++){                    lists.add(" " + i);                }                adapter.setData(lists);            }        });
