我阅读过使用ListView，但应该怎么做?并非所有行都是相等的，或者在任何情况下，中间都有一些元素与其他所有行都不相等！
I read to use a ListView, but how should I to do? Not all the rows are equal, or in any case there are some elements in the middle which are not equal to all other rows!

推荐答案
这肯定是ListView的理想候选者.正如我在评论中所述，您可以在Adapter中使用自定义的layout.我不知道您是如何获取数据的，所以我无法确切说明如何检查，但是在每一轮getView()中，您都可以检查数据并确定要显示/隐藏的View.
This definitely looks like a good candidate for a ListView. As I stated in my comment, you can use a custom layout in your Adapter. I don't know how you are getting your data for it so I can't say exactly how to check but in each round of getView() you can check the data and decide which Views to show/hide.
只需创建layout并添加TextView等，每行可能看起来像是在垂直LinearLayout的内部，水平LinearLayout在其中，或者只是RelativeLayout根据需要将visibility更改为visible/gone.
Simply create the layout with the TextViews, etc... that each row might need, looks like probably inside of a vertical LinearLayout with horizontal LinearLayouts inside or just a RelativeLayout then change visibility to visible/gone depending on what you need.
If you are unfamiliar with doing this then you can see this tutorial on doing it.
如评论中所指出的，如果您的layouts差异很大，则可以在Adapter的getView()方法中为不同的layout充气，这可能会使切换visibility成为一种不好的方法.这仅取决于您的数据和layout.
As pointed out in a comment, you could inflate different layouts in your getView() method of your Adapter if you have very different layouts which may make toggling visibility a bad approach. This just depends on your data and layouts.
