RelativeLayout add rule “RelativeLayout.LEFT_OF” not working

Question

I have a relativeLayout like below:

Answer 1

If your variable names are indicative, it's because you are adding the widget to a LinearLayout, so tags for a RelativeLayout get ignored.

This line is the one I'm talking about:

m_linearLayout.addView(button2, layoutParams);

EDIT

You say alignParentRight works... the only difference there is that ot doesn't take an anchor parameter. Perhaps m_listView.getId() isn't returning the proper id. You could step through with the debugger and see if it's returning a proper value.

Maybe you could try calling the id specifically...

layoutParams.addRule(RelativeLayout.LEFT_OF, R.id.list);
