You need to carefully override the following function:

@Override 
public boolean onKeyDown(int keyCode, KeyEvent event) {

    switch (keyCode) {
        case KeyEvent.KEYCODE_ENTER:
        {
            //your Action code
            return true;
        }
    }
    return super.onKeyDown(keyCode, event);
}

Use onKey() to capture the key. KEYCODE_NUMPAD_ENTER is used for the numeric ENTER key, and KEYCODE_DPAD_CENTER is the Directional Pad Center key.
