滚动视图中的可扩展列表视图未显示所有标题

Question

So, created Expandable List View today, implemented it in Scroll view, but I can only see one header (title) from parent_layout. You'll see it in first picture:

but there are 4 titles.

Second problem, whey I expand the list, other titles appear, but when all are expanded except the last one, you can't see the title:

You can see it one picture above, at the bottom of it.

Third problem, how can I reposition the arrow to the right and change the color? That one arrow circled in previous picture.

Here's my code:

\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 suggests not to use ListViews etc inside ScrollViews as they already have the scroll features themselves, but there are times when you need such a feature ( as yours)...so you must calculate your Expandable or ListViews height before rendering is done for the scroll...

here is how youll do it.

For your second problem changing indicator to the right.. you can modify the layout in your adapter and use custom image and hide and show it based on click eg here or you can calculate and reposition it using the inhouse method

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

eg here

Answer 2

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