i need scale image inside imageview, need use matrix doing so, so do; private void scaleimage(float scalefactor, float focusx,float focusy) { matrix displaymatrix= new matrix(); matrix.postscale(scalefactor, scalefactor); displaymatrix.set(matrix); imageview.setimagematrix(displaymatrix); } the problem no matter not able center image inside imageview, i need put image @ center (leaving white margins if image smaller view) i have been bangin head hours, please help. i have looked extensively @ https://stackoverflow.com/a/6172226/1815311, without success. all have find new x , y coordinates place image , translate matrix, image moves center of imageview. entire scaleimage method can this: private void scaleimage(float scalefactor, float focusx, float focusy) { matrix displaymatrix = new matrix(); matrix matrix = imageview.getimagematrix(); float x = (imageview.getwidth() - imageview.getdrawable().getintrinsicwidth() * scalefactor...
