Implicit “Submit” after hitting Done on the keyboard at the last EditText

Question

I\'ve used some apps where when I fill my username, then go to my password, if I hit \"Done\" on the keyboard, the login form is automatically submitted, without me having t

Answer 1

Simple and effective solution with Kotlin

Extend EditText:

fun EditText.onSubmit(func: () -> Unit) {
    setOnEditorActionListener { _, actionId, _ ->

       if (actionId == EditorInfo.IME_ACTION_DONE) {
           func()
       }

       true

    }
}

Then use the new method like this:

editText.onSubmit { submit() }

Where submit() is something like this:

fun submit() {
    // call to api
}

More generic extension

fun EditText.on(actionId: Int, func: () -> Unit) {
    setOnEditorActionListener { _, receivedActionId, _ ->

       if (actionId == receivedActionId) {
           func()
       }

        true
    }
}

And then you can use it to listen to your event:

email.on(EditorInfo.IME_ACTION_NEXT, { confirm() })
