Android PinnedSectionListView contraction

Android PinnedSectionListView contraction

Open-source projects on the Internet: https://github.com/beworker/pinned-section-listview. this project uses arrayadapter (). It is not suitable for me. You can make some modifications and simulate the interface.

PinnedSectionListView modifies a line of code. Otherwise, an error is reported. The Code is as follows:

Void createPinnedShadow (int position) {}"

 

if (layoutParams == null) {   //layoutParams = (LayoutParams) generateDefaultLayoutParams();layoutParams = new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);    pinnedView.setLayoutParams(layoutParams);}

Code AdapterListView:
