本文介绍了解决Android中RecyclerView在特定API版本下无法正确显示所有项的问题。通过将RecyclerView包裹在一个RelativeLayout中，并设置适当的属性，可以确保组件能适配其内容的高度。

其实只要布局中的recyclerView外面加上一层相对布局就可以了。  
  
 <RelativeLayout  
            android:layout_width="match_parent"  
            android:layout_height="wrap_content"  
            android:descendantFocusability="blocksDescendants">  
            <!-- DEV NOTE: Outer wrapper relative layout is added intentionally to address issue  
                 that only happens on Marshmallow & Nougat devices (API 23 & 24).  
                 On marshmallow API 23, the "RecyclerView" `layout_height="wrap_content"` does NOT  
                 occupy the height of all the elements added to it via adapter. The result is cut out  
                 items that is outside of device viewport when it loads initially.  
                 Wrapping "RecyclerView" with "RelativeLayout" fixes the issue on Marshmallow devices.  
            -->  
            <android.support.v7.widget.RecyclerView  
                android:id="@+id/my_recycler_view"  
                android:layout_width="match_parent"  
                android:layout_height="wrap_content"  
                tools:listitem="@layout/row_list_item">  
            </android.support.v7.widget.RecyclerView>  
        </RelativeLayout>

mPlateView.setLayoutManager(new GridLayoutManager(this, 3) {  
       @Override  
       public boolean canScrollVertically() {  
           return false;  
       }  
   });  
   mPlateView.setNestedScrollingEnabled(false);
