title: Android square imageview
body: <p>im trying to make a table with square imageviews (and all with the same size). The problem is that the images have different height and width.
  The table is 3x3 and i'd like to:
  each cell have a with = 1/3 of the screen width (maybe with the layout weight?) and height =width
  Much better if there is a way of define that in the xml than in code.
  Please explain it because im a noob with layouts weights =(
  Thanks in advance,</p>
