Explanation Needed In Android Code To Parse two different JSON Data from URL

Good day Android developers.

please i need inputs on how to display posts and comments on a new activity page i am presently working with json data from

jsonplaceholder-typicode,com/posts

sample json output for posts

{
"UserId": 1,
"Id": 1,
"Title": "to provide or to reject the blind are welcome option to find"
"Body": "And it takes \ nsuscipit follow accepted lightly with \ nreprehenderit discomfort may be the entire \ nnostrum of the things that happens is that they are extremely"
}

and

jsonplaceholder.typicode-com/comments

sample json output for comments

{
"postId": 1,
"id": 1,
"name": "id labore ex et quam laborum",
"email": "Eliseo@gardner.biz",
"body": "laudantium enim quasi est quidem magnam voluptate ipsam eos\ntempora quo necessitatibus\ndolor quam autem quasi\nreiciendis et nam sapiente accusantium"
}

This is my code below which displays post on a new list item. and when the list is clicked it takes the user to a new activity displaying just the title and the body.

I want to to be able to click a list item and it would display post title and comments in a new activity. any ideas please.

My Apologies for the long code i only want you all to see the big picture.

please find main activity code below
