Question: 

here is my code

for (int i = 0; i < StationNMArray.size(); i++) {
    String current_Station = StationNMArray.get(i);

    station_in_course = station_in_course + "\nStation: " + current_Station
            + "\nDate: " + year + "년 " +  month + "월 " +  day + "일"
            + "\nTime: " + currentHourArray.get(i) + "시 " + currentMinArray.get(i) + "분"
            + "\n예측값: " + currentPredict.get(i) + "\n";

    tv_data2.setText(station_in_course);

So, How can I do to visualize the value of currentPredict in a bar form like 0 is green and 250 is red in the current view?

What is the simplest way to implement it?
