ExpandableListView does not expanding when clicked?

Can you paste the whole code - the Adapter and the ListView. The layout also is needed. Meanwhile there are two possibilities - either you set a onGroupClickListener that always returns true (so that the click does not reach the super class) or something in the XML layout prevents the click event (clickable, etc.).

Try making the button in your group view non-focusable in your xml layout if it isn't already.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
