我在我的应用程序中使用导航抽屉，其中包含一个ListView来显示一些数据。我使用android.support.v4.widget.DrawerLayout lib完成了这个。现在我想在ListView Contain下面添加一个按钮抽屉。怎么做？
我的.xml是...........................................

/ ** ............................................ .................................................. .................................................. .................我需要在lstDrawerCart下面的按钮..........谁代表我的应用程序中的右抽屉.......但只需添加按钮的xml代码在这里不允许我在抽屉中表示按钮它只是作为MainActivity View。此外，我正在处理左和右抽屉，所以如果我需要在布局中包装它我怎么能这样做.......................... .................................................. .................................................. ........... * /

答案 0 :(得分：0)
android.support.v4.widget.DrawerLayout采用两个视图，第一个是主内容视图，第二个是抽屉幻灯片上绘制的视图。
所以我建议在布局中包装除主要内容之外的所有视图，并将其放在主要内容布局下。
编辑：
据我所知，您想在右侧抽屉的列表视图下添加一个按钮，因此您应该使用线性布局中的按钮包装列表视图，并且不要忘记将它的重力设置为右侧
