Hi, I want to load the tags when I first run the app, put them in the spinner item, and load the tags included in the selected spinner item. And I'm going to get all the values and make it a list.
!
for example, Let's see the data stored in the firebase.
The first time you run the app, Busan,area1,area2 appears as an item in the spinner.
I have completed this step.
However, if I choose area1, I would like to recall the sub-sections of area1,2,3,4.
And I want to make a list of all the values of the "date" through the dictionary among the data I have imported.
