I found the ADT Eclipse/SDK bundle, and it comes with a decent-looking UI editor.
I’ve tried to adapt it to the examples in the book, but the tool is not a very good XML editor; it gets all “weird” when I try to edit the raw XML (the edits won’t take, I can’t copy/paste from the book into the window…)
If I edit the XML outside Eclipse, it seems to work.
What I really wanted to try was the graphical elements, but the default Layout was a RelativeLayout, not a LinearLayout like the book has, and I found no way to change that.
Anyone had any success with this toolkit?
