Margins of a LinearLayout, programmatically with dp

Question

Is it possible to set the Margins of a LinearLayout, programmatically but not with pixels, but dp?

Answer 1

The following method works for me for converting pixels to dp:

int pixelToDP(int pixel) {
    final float scale = RaditazApplication.getInstance().getResources().getDisplayMetrics().density;
    return (int) ((pixel * scale) + 0.5f);
}
