Android execute function after pressing “Enter” for EditText

Question

I have been following the official Android tutorials and somehow am having a problem with this very simple example to execute a function after pressing \"Enter\" for an Edit

Answer 1

From what I can see, It looks like you have the wrong import.

Try

edittext.setOnKeyListener(new View.OnKeyListener() {

OR add this import

import android.view.View.OnKeyListener;

and Remove this one

import android.content.DialogInterface.OnKeyListener;

Answer 2

Delete the import statement that has DialogInterface, then import the View.OnKeyListener.

Answer 3

To receive a keyboard event, a View must have focus. To force this use:

edittext.setFocusableInTouchMode(true);
edittext.requestFocus();

After that continue with the same code in the example:

edittext.setOnKeyListener(new View.OnKeyListener() {
    public boolean onKey(View v, int keyCode, KeyEvent event) {
        // If the event is a key-down event on the "enter" button
        if ((event.getAction() == KeyEvent.ACTION_DOWN) &&
            (keyCode == KeyEvent.KEYCODE_ENTER)) {
          // Perform action on key press
          Toast.makeText(HelloFormStuff.this, edittext.getText(), Toast.LENGTH_SHORT).show();
          return true;
        }
        return false;
    }
});
