java - ScrollView 中的可扩展 ListView 未显示所有标题标题

Question

所以，今天创建了可扩展 ListView ，在 ScrollView 中实现了它，但是我只能从 parent_layout 中看到一个标题(标题)。你会在第一张图片中看到它:

但是有4个标题。

第二个问题，当我展开列表时，出现了其他标题，但是当除了最后一个之外的所有标题都展开时，您看不到标题:

你可以在上面的一张图片中看到它，在它的底部。

第三个问题，如何将箭头重新定位到右边并改变颜色？上一张图中圈出的那个箭头。

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 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.

\n\nZagrijavanje - za uspješno odrađen trening potrebno je razgibati se, povisiti brzinu rada srca i odraditi nekoliko serija glavnih vježbi s manjim kilažama.

Answer 1

Android 建议不要在 ScrollViews 中使用 ListViews 等，因为它们本身已经具有滚动功能，但有时您需要这样的功能(如您的)...所以您必须在渲染之前计算您的 Expandable 或 ListViews 高度完成滚动...

here是你会怎么做。

对于你的第二个问题，改变指标到右边..您可以修改适配器中的布局并使用自定义图像并根据点击隐藏和显示它，例如 here或者您可以使用内部方法计算并重新定位它

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

例如here
