Fluid Layout / Fluid ImageView Width

You must Login before you can answer or comment on any questions.

Hi all,

I'm having trouble making my Android app fit to different screen sizes. Although you've heard this question many times before, I'm yet to find a definitive answer by trawling through the Q&A or documentation.

I was under the impression that using dp values would mean "device independent pixels" and should be at least semi-fluid for 2 portrait screens.

I've been testing on a Samsung Galaxy S and a Samsung Galaxy Ace - Here's what I've tried so far for ImageView.width

  1. width:'85%' [crashes - is this a BUG ?]
  2. MyImgWidth = Math.floor(Ti.UI.currentWindow.width * 0.8); [crashes - is this a BUG ?]
  3. width: '175dp' [doesn't crash but inconsistent on the two screen resolutions]

God only knows what I'm going to do to get the app to fit on my GF's HTC Cha-Cha! :-D

Nevermind, thanks to this post I've finally figured it out like this: 

MyImgWidth = Math.floor(Titanium.Platform.displayCaps.platformWidth * 0.9);
MyImgHeight = Math.floor(MyImgWidth * 0.21);  //this figure pre-calculated by me -  Actual Image Width / Actual Image Height - as it is a horizontal button.
But the poster reckons you can do Math.Floor(win.width * 0.8) - which I've found to crash. Stick with Titanium.Platform.displayCaps.platformWidth
