i'm developing android application , have created imagebutton programatically:

int dps = 100; final float scale = getactivity().getbasecontext().getresources().getdisplaymetrics().density; int pixels = (int) (dps * scale + 0.5f);  imagebutton button = new imagebutton(getactivity()); button.setimageresource(r.drawable.button_start); button.setlayoutparams(new layoutparams((int)(pixels * 1.24f), pixels)); button.setscaletype(scaletype.fit_center); layout.addview(button);
