Answer 1

Use this, as you want to retain the current layoutParams:

ViewGroup.LayoutParams layoutParams = yourGridview.getLayoutParams();
layoutParams.height = 50; //this is in pixels
yourGridview.setLayoutParams(layoutParams);

Edit: If you want to input the height as dp instead of pixels, translate the dp amount to pixels:

public static int convertDpToPixels(float dp, Context context){
    Resources resources = context.getResources();
    return (int) TypedValue.applyDimension(
            TypedValue.COMPLEX_UNIT_DIP,
            dp, 
            resources.getDisplayMetrics()
    );
}

I think this should work:

GridView gridView = (GridView)findViewById(...);
ViewGroup.LayoutParams lp=new ViewGroup.LayoutParams(width,height);
gridView.setLayoutParams(lp);
