dynamically size image of an imagebutton in Android

Question

I have a problem sizing a picture into a imagebutton. Actually my button holds a image that is too large and I can see only a part of my picture on the imagebutton.

I have a activity with a layout which defines a webview with a button at the bottom in a sizerelation of 1/8. I mean the webview takes 8 parts of the screen and the button 1 part. My layout looks simplified like this :

WebView
  ...
  ...
  android:layout_weight="8" /
LinearLayout
  ...
  ...
  android:layout_weight="1"
  <ImageButton
  ...
  android:layout_weight="1"/
/LinearLayout

because of the weight definitions, I do not know the pixelsize of my button and I can't size my picture into the button correctly.

How can I size my image to the button correctly ? Or how can I manager that my button is sized correctly into my button ?
