In Android, the unit conversion between dip (dp) and px is dip2px dp to px without context algorithm (and to obtain the screen width and height), and androiddip2px

In Android, the unit conversion between dip (dp) and px is dip2px dp to px without context algorithm (and to obtain the screen width and height), and androiddip2px

Let's talk a little bit about the Code:

1. dip2px dp to px without context Algorithm

public static int px2dip(int pxValue){final float scale = Resources.getSystem().getDisplayMetrics().density;return (int) (pxValue / scale + 0.5f);}public static float dip2px(float dipValue){final float scale = Resources.getSystem().getDisplayMetrics().density;return  (dipValue * scale + 0.5f);}

2. Obtain the screen area

/*** Obtain the screen area */public static Rect getScreenRect () {DisplayMetrics displayMetric = new DisplayMetrics (); displayMetric = Resources. getSystem (). getDisplayMetrics (); Rect rect = new Rect (0, 0, displayMetric. widthPixels, displayMetric. heightPixels); return rect;}/*** get screen width **/public static int getScreenWidth () {return getScreenRect (). width ();}/*** get screen height **/public static int getScreenHeight () {return getScreenRect (). height ();}
