<!-- Onscreen in-call DTMF dialpad.  This element contains the grid of
     DTMF buttons (dialpad.xml) along with a TextView showing
     the digits you've typed.

     When the user presses the "Dialpad" button, this UI appears in the
     upper part of the in-call screen, covering up the "call card" area.
     The regular in-call controls (i.e. the InCallTouchUi widget) are
     still visible at the lower part of the screen.

     This layout is inflated in place of dtmf_twelve_key_dialer_stub
     in incall_touch_ui.xml. -->

    <!-- Display of the digits you've typed so far.
         This widget appears completely non-interactive to the user: you
         can't edit or "hit backspace" since these are DTMF tones you've
         already sent over the network.  But it's still an EditText rather
         than a TextView because it needs to receive key events from a
         hard keyboard, if present (see mDialerKeyListener). -->
