Unable to start activity:UnsupportedOperationException: addView(View, LayoutParams) is not supported in AdapterView

Question

I want to write a ListView in basic format but I get an error:

UnsupportedOperationException: addView(View, LayoutParams) is not supported in Ad         


        

Answer 1

If you're like me and totally skipped over the answer I needed in @Luksprog's answer because it's buried in it, try using adding the third parameter to the inflate method, also mentioned here:

inflater.inflate(R.layout.group_row, parent, false);

Don't use true instead of false or you will get the same error that brought you here, because it's trying to attach/add it to the parent, hence the addView is not supported in AdapterView error.
