The expandableLinearLayout must have at least one child.

the onMeasure method has the following lines:

if (childCount > 0) {
...
} else {
throw new IllegalStateException("The expandableLinearLayout must have at least one child");
}

Yes I see it, Thank you.
And I fixed this problem locally by ovverriding onMeasure method in my own class with try/catch and skip it.
I think, this throw not need in ExpandableLinearLayout - and can be erased!

public class ExpandableLinearLayoutNoException extends ExpandableLinearLayout {
@OverRide
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
try {
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
} catch (IllegalStateException ex){
// just skip such exceptions
}
}
}
