All I am trying to do is create a toast notification from a button click on a widget. I can get the widget (and button) to appear but I can't get my intent to fire.

This is what I have so far: public

问题 I had a working app on 2.1 and above until I tried to cleanup my initial layout with a theme of styles. Now the app won't even start with the "You must supply a layout_height attribute" failure message pointing to my first EditText View in the layout.
