</RelativeLayout>

I use GridLayout in the under of Relative Layout. I want to add 5 column in this But Not added. When I add 5 the column this is behave very bad. I want to make scientific Calculator And I want to use the Grid layout to arrange my all button.

I want to use 5X7 Table to arrange My all button. I try several times but I am not able to add 5th column in my code.

Simply removing the android:layout_columnWeight="1" and android:layout_rowWeight="1" will fix the problem.
