Disable soft keyboard on NumberPicker

Question

I\'m trying to deactivate the soft keyboard when using a NumberPicker to enter numerical values (for aesthetic reasons). This is my layout-xml-code:

Answer 1

I don't know why it works, but setting OnClickListener which does nothing prevented keyboard from showing (Lollipop)

numberPicker.setOnClickListener(new View.OnClickListener() {
  @Override
  public void onClick(View view) {
  }
});
