There is this feature that Eclipse had.
Assuming that you cause code completion in the middle of a word, the IDE gives you the ability to configure whether the proposed completion (the default behavior of Android Studio) will just be inserted or it should overwrite the entire word / expression.
Is there a similar configuration in Android Studio?
If, instead of pressing Enter, to use the choice of code completion, you use Tab, then code completion will overwrite what is in the carriage, and not just insert it.
