title: how can i resize imageButton?
body: <p>I want to resize my <code>ImageButton</code> using mouse on graphic layout or using code by 
  <code>android:layout_width</code> , <code>android:layout_height</code>. But whenever I do this, the <code>ImageButton</code> isn't resized, in fact and it's not smaller but it is cut at the edges. </p>
  
  <p>thanks in advance</p>
