    Hey,
    How can i set the layout_margin property of an ImageButton in code?

    Heres what i've got:
    Code (Text):
    1.     ImageButton ib = (ImageButton) findViewById(R.id.btn_learn);
    2.     MarginLayoutParams mlp = new MarginLayoutParams(ib.getLayoutParams());
    3.    
    4.     if(newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE)
    5.         mlp.setMargins(0, 20, 0, 0);
    6.     else
    7.         mlp.setMargins(0, 100, 0, 0);
    8.    
    9.     ib.setLayoutParams(mlp); // ERROR HERE
    Well, theres an error - classcastException - sure..
    The setLayoutParams wants an "LayoutParams" and im giving a "MarginLayoutParams".
    Well that was finally what I tried.

    Any ideas how i can make that working?
