I am working on an application that works as a city guide. It takes the data from a MySql database, it is divided by categories of each thing.
But I wanted to try to do it also by zones. I do not know if you understand. It would be like applying a double filter.
I added a Spinner al toolbar to select the zone and then they can select the category they want.
But the truth is that I could not think of how to do it! haha, the only way I thought is to create another category that is called North Zone for example and the locals of that area put them in their respective category and in North Zone appears in both.
Then from the spinner, select the north zone and show the locals. But obviously when you select a special category, all of them will appear to me. : s Could someone help me? this is my ActivityMain.java
