layout elements position problem

i've created an application for galaxy S..so i'm using 3.7 inch(resolution 320x480) layout for my xml files. The app is working perfectly on the phone. When using the same app in HTC wildfire whose resolution is 240x320 the g开发者_StackOverflow中文版raphics are out of position. I know the reason is obvious that I'm developing app in 3.7WVGA so graphics will not be compatible for QVGA.

Is the only solution is to create different versions of app on the basis of devices?? or is there a universal solution which i can implement so that the app will run without graphical repositioning on all the devices having different screen sizes and different resolution support??

please help me...coz i dnt really know the answer....and thank you in advance

If you can get away with it, use linear layouts and position things by weight. That way the ratios will stay the same and the same general appearance will hold.
