Among other things, my app displays photos in an ImageView in a popup
Dialog. These images come out of a database that is created on the
user's PC. Before storing them in the database, I resize them for max
dimensions of 320x320 pixels.
So, in almost all cases, on the Android device I simply display the
photos at their "natural" dimension, which fits nicely on almost all
screens. However, I have at least one customer with an HTC Wildfire
which, even though its screen is 3.2", has only QVGA dimensions
(240x320). With my current code, the photos do seem to be resized by the
system to display within the screen boundaries, but the rest of the
views in the dialog (caption, buttons, etc.) get "pushed off the screen"
and are not visible or usable.
Obviously I need to handle this case by setting some specific dimensions
on the ImageView when running on a QVGA device, but what is the best
approach? Should I use DisplayMetrics to discover the dimensions and
adjust accordingly? This would work, but seems like it might be too
low-level of an approach. Could I put dimension the image in the XML in
some way using "dips"?
(By the way, it's interesting that Android considers this class of
display to be a "small screen" for Manifest purposes, but at 3.2" it's
not physically all that smaller than a lot of other devices with higher
res.)
