Expands once but won't collapse

[Cliffus]

Hi Tomas

thanks for reporting this issue! If you want a quick fix for your problem, use android:maxLines="4" in your layout file instead of using expandText.setMaxLines(4); in your Activity / Fragment.

I'll add support for also using the setMaxLines() method.

Good luck!

Hi Michael

thanks for reporting this issue!

Can you provide me your layout file and a code snippet from your Fragment / Activity? I'll try to reproduce the issue on my side and help you out asap.

Thanks again!
Cliff

I have set max lines 4. On first load I have 4 lines. I click on the text, it expands. Than I click to collapse, it collapses to 4 and than expands back. Than if I click again nothing happens. Text stays expanded.
expandText.setInterpolator(new OvershootInterpolator()); expandText.setMaxLines(4); expandText.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { if(expandText.isExpanded()){ expandText.collapse(); } else{ expandText.expand(); } } });

Layout is a bit stripped down..

How ever, I used a different approach at the end and I don't have the orig element, but this is the fragment layout where I used the ExpandableTextView. Now I is just a simple TextView, just renamned that one so you can see where it was originally. Same thing happen to me as mentioned above.
Hope it helps...

Setting MaxLines in code is crucial for XML-free Kotlin's anko layouts...

[zacharee]

I've made a forked version of this library that allows setting the max lines in code: https://github.com/zacharee/Android-ExpandableTextView.

Here's the relevant commit: zacharee@5fc91d3

I just changed any calls to setMaxLines() inside the ExpandableTextView class to call the super method, and then overrode both setMaxLines() and getMaxLines() to properly set and report ExpandableTextView's maxLines field.
