How to set child weight in the code?

Question

I want that button(child) will have 25% of full width of horizontal LinearLayout (its parent). The code:

LinearLayout ll = new LinearLayout(this);
ll.setLayoutParams(new ViewGroup.LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.FILL_PARENT));
ll.setWeightSum (1.0f);

Button b = new Button (this);
ll.addView(b);

How can I do it? Thanks.

Try this:

    LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENTS,LayoutParams.FILL_PARENT));
    lp.weight = 0.25;
    b.setLayoutParams(lp);

You can pass it in as part of the LinearLayout.LayoutParams constructor:

LayoutParams param = new LinearLayout.LayoutParams(
                             LayoutParams.MATCH_PARENT,
                             LayoutParams.MATCH_PARENT, 1.0f);
