问题 I follow this tutorial to create a GridView : This line: imageView.setLayoutParams(new GridView.LayoutParams(85, 85)); Size 85x85 is great for my Wildfire, but on HTC Desire it looks very small.

DisplayMetrics metrics = new

问题 I'm working on an iOS app using PhoneGap. I ran into an annoying problem where some of my images weren't loading. Thinking it was a cache issue I played around swapping images. I finally discovered that the issue had to do with the height of my image. After a whole bunch of trial and error I discovered that an image taller than 7864px will not load in the iPad simulator or the iPad itself. It will load fine in Safari. It's not a file size limitation as these are only 45k in size and I'm

问题 I am trying, a few days now, to make a gallery with images with slightly different size, but with the same layout. As I can make it work in md view by forcing a 400px max-width for the container div, the workaround would create a gap below each image in xs and sm views. What I want to achieve is have a gallery with images of same max-width and same max-height, and of course, not distorted. http://www.bootply.com/qsy3HNl8DK Non responsive layout example: http://jsfiddle.net/npek7uxh/ <div
