Listener for Done button on EditText?

Code is

final EditText edittext = (EditText) findViewById(R.id.edittext);
edittext.setOnKeyListener(new View.OnKeyListener() {
    public boolean onKey(View v, int keyCode, KeyEvent event) {
        if (event.getAction() == KeyEvent.ACTION_DOWN && keyCode == KeyEvent.KEYCODE_ENTER) {
            Toast.makeText(HelloFormStuff.this, edittext.getText(), Toast.LENGTH_SHORT).show();
            return true;
        }
        return false;
    }
});

In that 'edittext' is id of textfield

Dinash answer is nice, but it is not working on all devices. Below code works fine for all devices

edittext.setOnEditorActionListener(new TextView.OnEditorActionListener() {
    @Override
    public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
        if (actionId == EditorInfo.IME_ACTION_DONE) {
            Toast.makeText(HelloFormStuff.this, edittext.getText(), Toast.LENGTH_SHORT).show();
            return true;
        }
        return false;
    }
});

The same Jone answer, but with replaced lambda:

etPointCombatFirst.setOnEditorActionListener((v, actionId, event) -> {
                if (actionId == EditorInfo.IME_ACTION_DONE) {
                    Toast.makeText(HelloFormStuff.this, edittext.getText(), Toast.LENGTH_SHORT).show();
                    return true;
                }
                return false;
            });

Kotlin Extension Solution

The base way to handle the done action in Kotlin is:

edittext.setOnEditorActionListener { _, actionId, _ ->
    if (actionId == EditorInfo.IME_ACTION_DONE) {
        // Call onDone result here
        true
    }
    false
}

Kotlin Extension

Use this to call edittext.onDone {/*action*/} in your main code. Keeps it more readable and maintainable

edittext.onDone { submitForm() }

fun EditText.onDone(callback: () -> Unit) {
    // These lines optional if you don't want to set in Xml
    imeOptions = EditorInfo.IME_ACTION_DONE
    maxLines = 1
    setOnEditorActionListener { _, actionId, _ ->
        if (actionId == EditorInfo.IME_ACTION_DONE) {
            callback.invoke()
            true
        }
        false
    }
}

Don't forget to add these options to your edittext Xml, if not in code

<EditText ...
    android:imeOptions="actionDone"
    android:inputType="text"/>
