What exactly is "id == EditorInfo.IME_NULL"?

android, ime

Solution

This code is preset everywhere when dealing with the "Enter" button on the soft keyboard.

The Andriod Documentation is not explicit, but IME_NULL is the generic key for "Enter"

This is also relevant in relation to IME's (Input Method Editor).

Problem

I see `id == EditorInfo.IME_NULL` used regularly in places which are supposed to match "Done" or "Enter" in addition to another condition such as the enter key or an IME action but I cannot find any explanation as to what exactly it is.
