Unit conversion between DIP (DP) and PX in Android dip2px DP to PX no context algorithm (and get get screen width and height)

Nonsense not much to say directly on the code:

1.DIP2PX DP to PX no-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. Get the screen area

    /**     * Get 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;    /**     * Gets the screen width * */public    static int getscreenwidth () {        return Getscreenrect (). width ();    /**     * Get screen height     *     *    /public static int getscreenheight () {        return Getscreenrect (). Height ();    }
