My main activity has multiple ArrayLists and Arrays. When you click the Smoked Cigarette button, the application logs certain information in the ArrayList. One of the ArrayLists locationsSmoked holds all the locations you've smoked at. My task is to make an activity that displays in a ListView the location you smoked at, and how many times you smoked there.
If you display the locationsSmoked array currently it will look like this
Home
Home
Home
Work
Work
School
School
and so on and so forth. I need to loop through this array to display the amount of times each string is called and give the integer value. I then need to combine the integer with the matching string. In a parallel array or multidimensional array to display the information in another activity named Locations in that activity's listview
So it looks like this
Home: 3
Work: 2
School: 2
It should be noted that even though you should never hard code elements, in this situation I literally am not allowed to because the ArrayList of locations will be constantly growing. There is another activity I've already completed that allows the user to add new locations to the existing ArrayList
I think the code I'm about to list below from my model.java and my locations.java is for the most part accurate. However nothing displays in the listview when i go to the activity.
So if that was confusing in any please let me know and I'll ask more specifically.
Thanks for any help you can offer.
