Android XML切断了布局的下半部分

Question

我的XML布局有问题,我认为这不会给我带来很多问题.我在滚动视图中有一个布局,但布局的底部被切断,我看不到第二个列表视图之外的任何内容.从环顾四周看,我似乎无法看到xml本身有什么问题,我看不出我做错了什么.

我已经尝试了对问题的建议,即为每个不同的元素添加权重,但这仍然没有解决问题.

我还添加了可能有助于解决问题的片段所在的主要活动

Answer 1

我解决了这个问题.在显示滚动视图时,底部被实际手机上的底部操作栏切断.因此,为了解决这个问题,我在scrollview的底部添加了填充,以便将其推回到操作栏上方.

新的布局如下
