Converting pixels to dp

Question

I have created my application with the height and width given in pixels for a Pantech device whose resolution is 480x800.

I need to convert height and width for a G1 device.
I thought converting it into dp will solve the problem and provide the same solution for both devices.

Is there any easy way to convert pixels to dp?
Any suggestions?

Answer 1

// Converts 14 dip into its equivalent px
float dip = 14f;
Resources r = getResources();
float px = TypedValue.applyDimension(
    TypedValue.COMPLEX_UNIT_DIP,
    dip,
    r.getDisplayMetrics()
);
