Question

因此，今天创建了可扩展列表视图，在Scroll视图中实现了它，但我只能从parent_layout中看到一个标题（标题）。你会在第一张图片中看到它：

但有4个标题。

第二个问题，乳清我扩展了列表，其他标题出现了，但是当除了最后一个之外都扩展了所有标题时，你看不到标题：

你可以在它的底部看到一张图片。

第三个问题，如何将箭头重新定位到右边并改变颜色？那张箭头在前面的图片中盘旋了。

这是我的代码：

\n\nNakon završena 4 tjedan potrebno je na sadašnji maksimum (u našem primjeru 180kg) dodati 5lbs (2.5kg) na potisak s klupe i potisak iznad glave te 10lbs (4.5kg) na čučanj i mrtvo dizanje. Vrlo je važno da ne nadodajete više od propisanog na kraju ciklusa jer će to nakon nekoliko mjeseci dovesti do stagnacije napretka.

\n\nDodatne vježbe za čučanj: prednji čučanj, dobro jutro, iskoraci s bučicama ili šipkom, nožna fleksija, nožna ekstenzija, ekstenzija za leđa.
\n\nDodatne vježbe za potisak s klupe: potisak s kose klupe šipkom ili bučicama, razvlačenje bučicama ili kablovima, propadanja.
\n\nDodatne vježbe za mrtvo dizanje: rumunjsko mrtvo dizanje, obrnuta hiperekstenzija, ekstenzija za leđa.
\n\nDodatne vježbe za potisak iznad glave: sljeganje ramenima, pregib za biceps bučicama ili šipkom, francuski potisak, hammer pregib, obrnuti pregib šipkom.

Answer 1

Android建议不要在ScrollViews中使用ListViews等因为它们本身已经有滚动功能，但有时你需要这样的功能（就像你的那样）...所以你必须在渲染之前计算你的Expandable或ListViews高度完成滚动...

here就是这样做的。

对于您的第二个问题，将指示器更改为右侧.. 您可以修改适配器中的布局并使用自定义图像并隐藏并根据单击here显示它或者您可以使用内部方法计算和重新定位它

setIndicatorBounds(int, int)
setIndicatorBoundsRelative(int, int)

例如here

Answer 2

问题的解决方案并非所有标题都显示：将ExpandableListView的高度设置为特定内容，例如200dp，而不是wrap_content, fill_parent or match_parent

滚动视图中的可展开列表视图未显示所有标题标题
