Programming For Various Screen Sizes in Android

Question

I'm using the Canvas and the SurfaceView. I've explicitly mentioned the coordinates for various objects and fonts on the screen. The app runs perfectly on Samsung Galaxy S Advance but the objects are out of scope on smaller screens such as that of Samsung Galaxy Fit or Pop. How do i make it compatible for all screen sizes and pixel densities. Using dpis seems out of the question as I'm not using any xml layouts.

Thanks in advance.

Answer 1

我认为您应该在运行时获得屏幕分辨率，并据此设置像素。

Answer 2

According to the developer guidelines it is discouraged to do so (work with explicit coordinates). Please refer to the android design guidelines for how to do it better. If you cannot avoid it, you'll need to take into account the screen size and density and compute your coordinates accordingly.
