What is the difference between text field types

I am new to android. I was stuck on a problem but I finally solved it.

I was using a TextField instead of CompleteTextViewField so whats the difference between these two and when should 开发者_如何学GoI use each one of them?

Thanks

Neither of those classes you mention (TextField, CompleteTextViewField) exist. Do you mean EditText and AutoCompleteTextView? I think the documentation explains it pretty well:

[AutoCompleteTextView is] An editable text view that shows completion suggestions automatically while the user is typing. The list of suggestions is displayed in a drop down menu from which the user can choose an item to replace the content of the edit box with.

That is, use it rather than a normal EditText if you have a set of common autocompletions for what gets entered in the box. The docs also link to a full sample that shows how to populate that list of suggestions with an Adapter.
