title: BaseInputConnection's commitText method doesn't get called when number clicked
body: <p>I'm trying to implement custom soft keyboard behaviour and met an issue. I overrode onCreateInputConnection() and extended BaseInputConnection class. Now I expect method commitText() gets called when a key is clicked... and it does unless the number key is clicked. The number key goes directly to sendKeyEvent() method. Is there a way to handle numeric keys like any other keys? Thanks.</p>
  
  <p>Here is the onCreateInputConnection method implementation. Nothing special.</p>
  
  <pre><code>@Override
  public InputConnection onCreateInputConnection(EditorInfo outAttrs) {
      outAttrs.inputType = InputType.TYPE_CLASS_NUMBER;
      outAttrs.imeOptions = EditorInfo.IME_ACTION_NONE;
      return new BaseInputConnection(this, true) {
          @Override
          public Editable getEditable() {
              return editable;
          }
  
          @Override
          public boolean commitText(CharSequence text, int newCursorPosition) {
              return super.commitText(text, newCursorPosition);
          }
  
          @Override
          public boolean sendKeyEvent(KeyEvent event) {
              return super.sendKeyEvent(event);
          }
      };
  }
  </code></pre>
