if you want use it with <code>LinearLayoutManager</code>

<pre><code>&lt;android.support.v7.widget.RecyclerView
 xmlns:app="http://schemas.android.com/apk/res-auto"
 app:layoutManager="android.support.v7.widget.LinearLayoutManager" &gt;
</code></pre>

that equivalent to 

<pre><code>LinearLayoutManager mLayoutManager = new LinearLayoutManager(getApplicationContext());
mRecyclerView.setLayoutManager(mLayoutManager);
</code></pre>

blocks|key|4431241|text|我使用的最常见的方法是：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4431242|<androidx.recyclerview.widget.RecyclerView
++++app:layoutManager="androidx.recyclerview.widget.GridLayoutManager"+
++++tools:listitem="@layout/grid_item"

++++android:orientation="vertical"/>|4431245|建议设置listitem，这样您就可以在布局编辑器的预览中看到它的样子。|offset|length|style|CODE|4431246|但是，如果你想颠倒顺序，我认为你必须用代码来做，如果你真的想看到什么，就用XML中的“工具”……|4431247|entityMap^0|0|0|0|0|4|8|0|0^^$0|@$1|2|3|4|5|6|7|U|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|V|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|W|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|X|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|Y|8|@$M|Z|N|10|O|P]]|9|@]|A|$]]|$1|Q|3|R|5|6|7|11|8|@]|9|@]|A|$]]|$1|S|3|-4|5|6|7|12|8|@]|9|@]|A|$]]]|T|$]]

The most common ones that I use are:

<pre><code>&lt;androidx.recyclerview.widget.RecyclerView
 app:layoutManager="androidx.recyclerview.widget.GridLayoutManager" 
 tools:listitem="@layout/grid_item"
 android:orientation="vertical" app:spanCount="3"/&gt;
</code></pre>

And:

<pre><code>&lt;androidx.recyclerview.widget.RecyclerView
 app:layoutManager="androidx.recyclerview.widget.LinearLayoutManager"
 tools:listitem="@layout/grid_item"
 android:orientation="vertical"/&gt;
</code></pre>

It's recommended to set <code>listitem</code> , so that you'd see how it could look in the preview of the layout editor.

If you want to have the order reversed though, I think you have to do it in code instead, and use "tools" in XML if you really want to see something...

blocks|key|4431287|text|这对我来说很有效--只需添加app:layoutManager="LinearLayoutManager"，就可以了|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|4431288|++++<android.support.v7.widget.RecyclerView

This worked for me - just add <code>app:layoutManager=&quot;LinearLayoutManager&quot;</code> and you're good to go
<pre><code> &lt;android.support.v7.widget.RecyclerView
 android:id=&quot;@+id/recordItemList&quot;
 android:layout_width=&quot;match_parent&quot;
 android:layout_height=&quot;match_parent&quot;
 android:orientation=&quot;vertical&quot;
 android:clipToPadding=&quot;false&quot;
 android:scrollbars=&quot;none&quot;
 app:layoutManager=&quot;LinearLayoutManager&quot;
 app:stackFromEnd=&quot;true&quot;
 app:reverseLayout=&quot;true&quot;/&gt;
</code></pre>

You can set the layout manager for recyclerview like this, <code>app:layoutManager=&quot;androidx.recyclerview.widget.LinearLayoutManager&quot;</code>
