Set height and width dynamically according to the screen size. this is the best way to get perfect result.

DisplayMetrics displaymetrics = new DisplayMetrics();
        ((Activity) context).getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
        //if you need three fix imageview in width
        int devicewidth = displaymetrics.widthPixels / 3;

        //if you need 4-5-6 anything fix imageview in height
        int deviceheight = displaymetrics.heightPixels / 4;

        holder.image_view.getLayoutParams().width = devicewidth;

        //if you need same height as width you can set devicewidth in holder.image_view.getLayoutParams().height
        holder.image_view.getLayoutParams().height = deviceheight;

try this in adapter in getview hope you get better result in all device

EDIT: Or to set same height same as width you can set devicewidth in height also like below:

holder.image_view.getLayoutParams().height = devicewidth;
