@Override
protected boolean matchesSafely(TextView textView) {
  String text = textView.getText().toString();
  // The reason we try to match both original text and the transformated one is because some UI
  // elements may inherit a default theme which behave differently for SDK below 19 and above.
  // So it is implemented in a backwards compatible way.
  if (stringMatcher.matches(text)) {
    return true;
  } else if (textView.getTransformationMethod() != null) {
    CharSequence transformedText =
        textView.getTransformationMethod().getTransformation(text, textView);
    if (transformedText != null) {
      return stringMatcher.matches(transformedText.toString());
