I have three useful functions in my library...

get Screen Density

public static float getDensity(Context context){

}

convert Dip to Pixels.

public static int convertDiptoPix(int dip){
    float scale = getDensity();
    return (int) (dip * scale + 0.5f);
}

    return (int)((pixel - 0.5f)/scale);
}
