问题描述
我的XML布局有问题，我认为这不会给我带来很多问题.我在滚动视图下面有一个布局，但是该布局的底部已被切除，在第二个列表视图之后看不到任何内容.从四周看，我似乎看不到xml本身有什么问题，也看不到我做错了什么.
I have a problem with my XML layout, something that I thought wouldn't give me many problems. I have a layout below in a scroll view, but the bottom of the layout is being cut off, I can't see anything past the second list view. From looking around, I can't seem to see anything wrong with the xml itself and I can't see what I am doing wrong.
我已经尝试过解决这个问题的建议，那就是增加每个不同元素的权重，但这仍然不能解决问题.
I have tried the suggestion to the problem, that is adding a weight to each of the different elements but this still hasnt solved the problem.
我还添加了将片段放置在其中的主要活动，以防可能有助于解决问题
I have also added the main activity in which the fragment is placed incase that might help solve the problem

推荐答案
我解决了这个问题.在显示滚动视图时，实际电话上的底部操作栏将底部切除.因此，为解决此问题，我在滚动视图的底部添加了填充，以便将其向上推回操作栏上方.
I solved the issue. As the scroll view was being displayed the bottom was being cut off by the bottom action bar on the actual phone. So to solve this I added padding to the bottom of the scrollview in order to push it back up above the action bar.
新布局如下
