Android: Reduce space between columns in GridView

Question

See attached screenshot where I am attempting to reduce the space between the columns in my GridView.

My main.xml is as follows:

Answer 1

I was having similar issue of having slight horizontal spacing between the columns in few devices. ( I did not required any space. ) I was properly calculating the grid item width by dividing it with total width. I was getting this issue only on Lenovo devices.

following code was in activity related to grid.

int myRequestedColumnWidth = myGridViewContentMain.getRequestedColumnWidth();

Point size = new Point();
getWindowManager().getDefaultDisplay().getSize( size );
int width = size.x;
int height = size.y;

int myGridColumns = width / myRequestedColumnWidth;

if ( myGridColumns == 0 || myGridColumns == 1 )
    myGridColumns = 2;
myColumnWidth = ( width / myGridColumns );

myGridViewContentMain.setNumColumns(myGridColumns);

following code was in layout xml for grid

I was unable to solve issue after changing stretch mode values.

But following value in layout xml for GridView did the trick.

    android:horizontalSpacing="0dp"

I hope, someone like me may find this helpful.

Regards.
