问题 I'm trying to center an ImageView inside a LinearLayout horizontally and vertically, but I just can't do it. The main reason why I'm not using a RelativeLayout for that is because I need the layout_weight (my Activity consists of four columns that should be equally divided, and also responsive to different screen widths, each column having an ImageView centered and unstretched).
