first of all, I'm aware of the title being a a bit ambiguous, so I'm going to try to explain the issues I'm having more clearly.
I've created a program that imports data from csv.files, which consists of measure points like date, time, heart rate etc. The user is first met with a login screen, that connects to a database, which then lets the user get access to the mainframe of the program.
The program consists of a class called Activity, which has a method that reads the activity, along with some other methods. This class then gets impemented by another class called Datapoint, which splits the different values from the csv.files into measuring points like date, time, longitude and latitude.
Finally, the third class that only consists of data is called Statistics, which takes the values and adds them into datapoints such as average, min and max speed etc.
Now to my problem. I've created a GUI for this which let's the user import csv.files, and then add the datapoints from the file into a map, a plotted diagram, and a page which shows the values from the statistics class. This works fine, and everything is updated when imported.
The activities chosen are then being added to a JList, from where the user can chose a certain activity, which preferrably a mouselistener. When the activity in the list is double-clicked, the graphs should update with the chosen activity's datapoints from the list, but I don't know how to do it. The other issue is that the imported activity writes over the old one, so that the JList contains a duplicate of the activities imported.
Instead of just showing the GUI, I figured I'd provide you with all the information regarding the classes that the GUI handles, so it's easier for you to pinpoint how I should solve my problem. I'll post the Classes below.
Activity:
package model;
import java.io.BufferedReader;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.IOException;
import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;
public class Activity {
private String file;
private String title;
private String location;
private String note;
private String activityType;
private String category;
private List<DataPoint> dataPoints = new ArrayList<DataPoint>();
private String line = "";
//private String[] dataPoints;
public Activity (){
//csvFileReader("activity_103378385.csv");
}
public void csvFileReader(String file) {
try {
this.file = file;
BufferedReader in = new BufferedReader(new FileReader(file));
line = in.readLine(); // läser bort första raden av aktiviteten
while ((line = in.readLine()) != null) {
line = line.replaceAll(",", ".");
String[] data = line.split(";");
dataPoints.add(new DataPoint(data));
}
in.close();
/* for (DataPoint act : dataPoints)
System.out.println(act); */
}
catch (FileNotFoundException e) {
e.printStackTrace();
}
catch (IOException e) {
e.printStackTrace();
}
}
public List<DataPoint> getData() {
return dataPoints;
}
public void clear() {
dataPoints.clear();
}
public String getTitle() {
return title;
}
public String getLocation() {
return location;
}
public String getNote() {
return note;
}
public String getActivityType() {
return activityType;
}
public String getCategory() {
return category;
}
@Override
public String toString(){
return file.substring(file.lastIndexOf("\\")+1, file.length()-4);
}
}
And the GUI (where I'm facing the difficulties):
