问题 I have a simple todolist app I'm creating whereby new todo items are added via an EditText View. So I'm trying to have it submit the new item to the list when I press the enter key . For some reason though it just enters a new line instead . I have also noticed that it works fine when I use the enter key via an AVD through eclipse but the problem only occurs when I'm running it through my Nexus 4.
