Buggy source:
@Override public View getView(int position,View convertView,ViewGroup parent){
  if (convertView == null)   convertView=getActivity().getLayoutInflater().inflate(R.layout.list_item_result,parent,false);
  Result result=getItem(position);
  DynamicTextView textViewUnitDesc=(DynamicTextView)convertView.findViewById(R.id.list_item_result_convertUnitDesc);
  TextView textViewUnitTimestamp=(TextView)convertView.findViewById(R.id.list_item_result_currencyTimestamp);
  textViewUnitTimestamp.setVisibility(View.GONE);
  if (result != null && result.containsUnits()) {
    String text=getResources().getString(R.string.word_Converting) + "String_Node_Str" + result.getQueryUnitTextLong()+ "String_Node_Str"+ getResources().getString(R.string.word_to)+ "String_Node_Str"+ result.getAnswerUnitTextLong()+ "String_Node_Str";
    textViewUnitDesc.setText(Html.fromHtml("String_Node_Str" + text + "String_Node_Str"));
    textViewUnitDesc.setVisibility(View.VISIBLE);
    String timestamp=result.getTimestamp();
    if (!timestamp.equals("String_Node_Str")) {
      textViewUnitTimestamp.setText(timestamp);
      textViewUnitTimestamp.setVisibility(View.VISIBLE);
    }
  }
 else {
    textViewUnitDesc.setVisibility(View.GONE);
  }
  TextView textViewQuery=(TextView)convertView.findViewById(R.id.list_item_result_textPrevQuery);
  setUpResultTextView(textViewQuery,result.getTextQuery());
  TextView textViewAnswer=(TextView)convertView.findViewById(R.id.list_item_result_textPrevAnswer);
  setUpResultTextView(textViewAnswer,result.getTextAnswer());
  return convertView;
}

Fixed version (ground truth):
@NonNull @Override public View getView(int position,View convertView,@NonNull ViewGroup parent){
  if (convertView == null)   convertView=getActivity().getLayoutInflater().inflate(R.layout.list_item_result,parent,false);
  Result result=getItem(position);
  DynamicTextView textViewUnitDesc=(DynamicTextView)convertView.findViewById(R.id.list_item_result_convertUnitDesc);
  TextView textViewUnitTimestamp=(TextView)convertView.findViewById(R.id.list_item_result_currencyTimestamp);
  textViewUnitTimestamp.setVisibility(View.GONE);
  if (result != null && result.containsUnits()) {
    String text=getResources().getString(R.string.word_Converting) + "String_Node_Str" + result.getQueryUnitTextLong()+ "String_Node_Str"+ getResources().getString(R.string.word_to)+ "String_Node_Str"+ result.getAnswerUnitTextLong()+ "String_Node_Str";
    textViewUnitDesc.setText(ViewUtils.fromHtml("String_Node_Str" + text + "String_Node_Str"));
    textViewUnitDesc.setVisibility(View.VISIBLE);
    String timestamp=result.getTimestamp();
    if (!timestamp.equals("String_Node_Str")) {
      textViewUnitTimestamp.setText(timestamp);
      textViewUnitTimestamp.setVisibility(View.VISIBLE);
    }
  }
 else {
    textViewUnitDesc.setVisibility(View.GONE);
  }
  TextView textViewQuery=(TextView)convertView.findViewById(R.id.list_item_result_textPrevQuery);
  setUpResultTextView(textViewQuery,result.getTextQuery());
  TextView textViewAnswer=(TextView)convertView.findViewById(R.id.list_item_result_textPrevAnswer);
  setUpResultTextView(textViewAnswer,result.getTextAnswer());
  return convertView;
}
