I have developed an android application and run it on an HVGA emulator. It's running successfully on any HVGA device i.e. mdpi. But if I try to run on small screen resolution devices i.e QVGA then my buttons are looking as if they go down and dont fit onto the small screen...
So how can I run my android application on multiple screen resolution successfully?
I think it is better to design your layout for every screen size and resolutions. It is easy in android. Copy your layout from "layout" folder of resources and paste it in the "layout-land", "layout-xlarge", "layout-xlarge-land" and ... folders and change those settings you need in them.
you can check this link:
follow these instructions
What happens with this approach:
if the device has a non-small screen, the default layout (the one in "layout" folder) will be loaded and used, otherwise if the screen is in "small" category the files in "layout-small" will be used instead (only if one with the same name is available, otherwise the one in "layout" will be used
*About folder naming: that policy was the old one supported by android. Nowadays there is another one, more precise but more complex too (example: specify minimum necessary width). Anyway, this is still supported, just note that eclipse may suggest you some alternatives. Currently, i am still developing with the old naming policy.
In the UI builder (part of the Eclipse plugin), you can build your interfaces for multiple screen sizes and resolutions. To make different layouts for different resolutions, simply follow these instructions to build alternate layouts:
