Answer 1

I used a variation of Shawn's solution.. it looks nice on the Emulator.

1) Decide on the # of columns, I chose 4

2) Set the Column Width

float xdpi = this.getResources().getDisplayMetrics().xdpi;
int mKeyHeight = (int) ( xdpi/4 );

GridView gridView = (GridView) findViewById(R.id.gridview); 
gridView.setColumnWidth( mKeyHeight );// same Height & Width

3) Setup the image in your adapter's getView method

imageView = new ImageView( mContext );
// (xdpi-4) is for internal padding
imageView.setLayoutParams(new GridView.LayoutParams( (int) (xdpi-4)/2, (int) (xdpi-4)/2));
imageView.setScaleType( ImageView.ScaleType.CENTER_CROP );
imageView.setPadding(1, 1, 1, 1);

4) Layout

That's it.
