last item diplay empty
I use android-advancedrecyclerview to display prod list, product's name is header, product's detail is child. in some phone , when last group item scrolling to visiability , the child 's button and editext display emtpy , very strange.
thank you for help.
Hmm. This seems very strange. Is the issue occurs every time on specific devices? Have you verified that bindViewHolder() is called for the last item?
Also, I want more info to investigate the issue;
- Version of Advanced RecyclerView
- Version of support libraries
- Android OS version
- Which features (DnD, swipe, expand, ...) do you use?
- How many item view types int the list?
Thanks.
thanks for your response very much.
- advrecycler_view_version = '0.8.6@aar' // I have test ver.0.10.3 ，the issue occurs also .
- android_support_version = '24.2.1'
- Android OS and Phone: 4.4.2 (19)，Huawei:HUAWEI P7-L07:armeabi-v7a (ps: the phone have the Navigation Bar the bottom, as menu,home, back)
- Just use expand
- just one view types , bindViewHolder is called ,I has debug this case。
when view init, list has 4 items ,last item's header visiblity, last item 's child under the virtual key , scroll up ,the strang thing must come, textview.settext("string") is ok, but EditText and Button setText do not work, is empty. the stranger thing is , when list more then 6 items , everything is ok ,last item do work.

@lengxf Hi. I have checked your adapter code over and over again, but I cannot find out any reasons that cause the issue.
However, I am now curious about the CheckDisplayChildViewHolder. I guess this class is attaching a TextWatcher to EditTexts in its constructor 🤔
@h6ah4i Yes, you guess right. Every EditText has one more TextWatchers:
class CheckDisplayChildViewHolder extends BaseViewHolder {
private static final int MAX_INT = 99999;
private static final Double MAX_DOUBLE = 99999.999;
public final Button mUnitPrice;

}

I think TextWatcher do not lead the problem . Other child item work well, TextWatcher is the same . I do not know different ondraw between EditText and TextView , TextView make work, why not do EditText at that stuation?
