  • 0

In Android Google Mail app, when you start typing into the “To:” field in a new email, you will get a dropdown menu, auto-populated from your contacts.

I want this behavior in my app.

Currently, when my users enter an email address, they have to type the whole thing (into, essentially, an “textEmailAddress” input field). I want to make things easier by providing contacts-based predictive entry, Google-Mail-style.

How do I do this?

(So far, I have 1. googled, 2. looked through Android SDK documentation, 3. looked through Android sources (http://grepcode.com/project/repository.grepcode.com/java/ext/com.google.android/android/).)
