Recyclerview嵌套recyclerview的深坑，对于一个新手来说怎么也上不去，特来邀请键盘中的高手高高手，拉拉我;
第一个Recyclerview布局：
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/area_LinearLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:focusable="true"
android:focusableInTouchMode="true"
android:orientation="vertical">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="40dp"
android:background="@drawable/drawable_black_one"
android:orientation="horizontal"
android:layout_margin="3dp">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="5dp"
android:layout_gravity="center"
android:text=""
android:textColor="@drawable/drawable_white_pure"
android:lines="1"
android:layout_weight="1"/>
<TextView
android:layout_width="1dp"
android:layout_height="30dp"
android:layout_gravity="center"
android:layout_margin="5dp"
android:background="@color/whiteness"
/>
<TextView
android:id="@+id/peers_location_TextView"
android:layout_width="70dp"
android:layout_height="40dp"
android:layout_marginLeft="5sp"
android:layout_marginRight="10dp"
android:ellipsize="end"
android:gravity="center"
android:text=""
android:textColor="@color/whiteness"
android:textSize="14sp"
android:lines="1"
android:textStyle="bold" />
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="3dp"

<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"

<ImageView
android:layout_width="20dp"
android:layout_height="20dp"

android:layout_alignParentEnd="true"
android:layout_marginTop="0dp"
android:layout_marginEnd="10dp"
android:scaleType="fitStart"
android:src="@drawable/location" />
</RelativeLayout>
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="40dp"
android:background="@drawable/drawable_black_one"

<TextView
android:layout_width="50dp"
android:layout_height="wrap_content"

android:textSize="14dp"
android:layout_marginLeft="14dp"
android:layout_gravity="center"
android:textColor="@color/whiteness"
android:layout_margin="5dp"
android:gravity="center"/>
</LinearLayout>
<android.support.v7.widget.RecyclerView
android:id="@+id/user_info_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
</LinearLayout>
在第一个Recycleview的item里面嵌套了第二个Recyclerview不知道这样对不对？
