问题 I've got a layout that I'm trying to set up that is comprised of three different layouts merged into one. I have two RelativeLayouts as the first two items and a list adapter as the third. The reason for using MergeAdapter is because I want the entire page to scroll, but I want the second total item in the entire layout (the second RelativeLayout) to stick to the top. So I'm trying to use the StickyListHeaders Library to accomplish it. It doesn't seem like it's too widely used yet, even

问题 Goal: I am trying to create a UI with 2 checkboxes per line, each line seperated into sections. I've included a screenshot of the UI below. Current approach: I am using an ExpandableListView and handeling the data with an onChildClick. Problem: When you click a checkbox, it does not trigger onChildClick or anything else. Clicking anywhere outside of the checkbox will trigger this event. Research: There are lots of threads that suggest setting android:focusable="false", but that doesn't change
