Android - How to specify weight programmatically for RelativeLayout?

Question

I want to do something like this programmatically -

<LinearLayout> <RelativeLayout1 weight = 1> <RelativeLayout2 weight = 3> <RelativeLayout3 weight = 1> <LinearLayout> 

This does not allow me to do setWeight programmatically. However, I see that RelativeLayout has an android: layout_weight parameter in XML. Did I miss something?

Answer 1

When you add a RelativeLayout to LinearLayout using addView, you should provide LinearLayout.LayoutParams, something like this:

 LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(width, height, weight); linearLayout.addView(relativeLayout, params);
