问题描述

我在将Adview放在RecyclerView下方时遇到麻烦.当前RecyclerView占据了其余的布局，并且Adview没有显示.我在网上找到的所有解决方案都没有解决我的问题.通常layout_weight或layout_below可以解决问题，但不是这种情况.

I'm having trouble placing an Adview below a RecyclerView. Currently the RecyclerView is taking up the rest of the layout and the Adview isn't being shown. None of the solutions I have found online have solved my issue. Usually layout_weight or layout_below solves the problem but it isn't in this case.

我重写了布局文件，将recycleview封装在linearlayout内

I rewrote your layout file, The recycleview is wrapped inside a linearlayout

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"

    android:layout_width="match_parent"
    android:layout_height="match_parent">

<LinearLayout
   android:id="@+id/wrapper"
   android:layout_width="match_parent"
   android:layout_height="60dp"
   android:layout_alignParentTop="true"
   android:layout_centerHorizontal="true"
   android:layout_marginBottom="12dp"
   android:orientation="vertical">

   <android.support.v7.widget.RecyclerView
       android:id="@+id/recycler_view"
       android:layout_width="match_parent"
       android:layout_height="wrap_content"
       android:clipToPadding="false"
       android:paddingBottom="20dp"
       android:paddingLeft="@dimen/activity_horizontal_margin"
       android:paddingRight="@dimen/activity_horizontal_margin"
       android:paddingTop="10dp" />

   </LinearLayout>

            <Spinner

                android:layout_height="match_parent"
                android:layout_weight="1.0" />
        </TableRow>
    </TableLayout>
</RelativeLayout>

结果如下所示

如果回收视图的内容将超出显示高度，则应考虑使用android:layout_weight将布局划分为多个分区.

If your recycleview content will extend beyond the display height then you should consider dividing your layout into partitions with android:layout_weight.
