我在这个tutorial
中使用了SlidingDrawer它在LinearLayout中工作,但总是有一个空格,取决于滑块的高度,所有其他东西都显示在空格下面。
解决方案应该是使用相对布局。这会删除空格,但滑块中的处理程序按钮似乎位于滚动视图中的内容之下,并且不会通过单击它来执行任何操作。查看截图

滑动时,滑块应与滚动视图重叠
答案 0 :(得分:1)
在视图层次结构术语中,在布局XML
开头定义的视图更深入&#34;比后来定义的那些。
在您的情况下,您的ScrollView
会在SlidingDrawer
之后添加到层次结构中,因此您所期待的将会如此。
将SlidingDrawer
移至ScrollView
以下,并且应高于input()
。
