To calculate screen density, you can use this equation:

Screen density = Screen width (or height) in pixels / Screen width (or height) in inches

Density can be calculated by the following formula:

Density = sqrt((wp * wp) + (hp * hp)) / di

Where:

wp is width resolution in pixels,

hp is height resolution in pixels, and

di is diagonal size in inches.

int pixel = 120;
final float scale = getResources().getDisplayMetrics().density;
int dip = (int) (pixel* scale + 0.5f);

The formula is actual-dpi / 160. (Everything is scaled to 160 dpi.)
