Removing buttons programmatically

In my code I create buttons programmatically as I do not know how many I need until a file is parsed

buttons= new LinkedList<Button>();
    for(int i=0; i< aList.size();i++)
    {
        Button btn = new Button(this);
        btn.setId(i);
        btn.setOnClickListener(this);
        btn.setText(stringList.get(i));
        btn.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
        buttons.add(btn);
        layout.addView(btn);
    }

This works fine, I'm just wondering if there is a quick way to delete all these buttons before creating more (I change the values of the buttons to new ones when the user presses an seperate button)

Solved the problem with another for loop

for(int i=0; i< aList.size();i++)
    {
        Button btn;
        btn = buttons.get(i);
        layout.removeView(btn);
    }

You can do something like this

View v = (View) findViewById(id);
((ViewManager)v.getParent()).removeView(v);

You can set invisible.

myButton.setVisibility(View.INVISIBLE);
