Answer 1

You can get column count in java code..

GridView mGridView = (GridView)findViewById(R.id.gridview);
int column_coutnt = mGridView.getNumColumns();

Second Way:

int columns = 0;
int children = mGridView.getChildCount();
if (children > 0) {
     int width = mGridView.getChildAt(0).getMeasuredWidth();
     if (width > 0) {
        columns = mGridView.getWidth() / width;
     }
 }            

Answer 2

Try like this..

Math.ceil( (double)gridView.getCount() / (double)gridView.getNumColumns() );
