本文介绍了一个简单的解决方案来解决RecyclerView在特定Android版本上（如Marshmallow和Nougat）的高度显示不全的问题。通过在外层添加一个RelativeLayout并设置适当的属性，可以确保RecyclerView能够正确展示所有项，即使使用了wrap_content。

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);
