title: Android: how to ignore Enter key so the focus won't change
body: <p>I have an Activity with two EditText fields. So when I press enter in the first one the second one becomes focused.</p>
  
  <p>However I want to disable Enter key in the first EditText sometimes (for example when I think that the user haven't made a proper input into the first EditText).</p>
  
  <p>I' ve overwriten onKeyDown for the 1st EditText returning true when key event is KEYCODE_ENTER but that doesn't help.</p>
  
  <p>What shall I do?</p>
