Retrieve data from a specific array from a json

Question

I have a admin app written with Java to be able to manage my users

I created a custom json

This is what my JSON looks like

[
  {
    "userId": 1,
    "email": "user1@gmail.com",
    "sponsorship": true,
    "create": 274
  },
  {
    "userId": 2,
    "email": "user2@gmail.com",
    "sponsorship": false,
    "create": 201
  },
  {
    "userId": 3,
    "email": "user3@gmail.com",
    "sponsorship": false,
    "create": 189
  }
]

In my List I just display email address

Now my problem, for example if I click on the List which contains the email user1@gmail.com , I want to display in a Dialog the data related to this email, ie the userId , sponsorship and create

How ​​can I retrieve the other values ​​using the email?

I couldn't find anything about it on the internet

Answer 1

When reading your json file, you need to make it understandable. There is an example of making it understandable in the link below.

You have to write a condition after these procedures. The condition should be:

for(int i=0; i< employeeList.size;i++){
    if(employeeList[i].email.equals("user3@gmail.com")){
//the person you are looking for
var person = employeeList[i];
}
}
