How to know Gridview last colum in every row android

Question

In getView(int position, View convertView, ViewGroup parent) method of an adapter how to know if position is reflecting the last column of the row ?

For example:

1 2 3
4 5 6
7 8 9

Let say this is GridView then element 3,6 and 9 are last column of row 1,2 and 3 respectively.

Ask the grid, how many columns you have:

int numColumns = ((GridView) viewGroup).getNumColumns();

after that you could use the '%' operation:

boolean isLast = (position % numColums) == 0;

No the columns are different in different devices GridView is having the following properties: android:numColumns="auto_fit" android:stretchMode="columnWidth" – yashodhan divakaran Apr 08 '15 at 10:32
Then use 'int numColumns = ((GridView) viewGroup).getNumColumns();' and after that you can do the '%' operation – user3621165 Apr 08 '15 at 10:33
But getNumColumns() will return -1 i.e AUTO_FIT if the Grid has never been laid out. – yashodhan divakaran Apr 08 '15 at 10:38

Solution: Call mGridView.getNumColumns() in getView() of the adapter.This will give the number of columns a row can have. Once we have that we can easily know which position is going to be the last column of the row.
