How to get a name or word from a string that is inside a JSON value in Android Studio?-CodePudding

I'm not sure If the title is correct, but I'll explain what I mean. So I'm doing a project that involves an API. I created the data classes that was need to store that information as well. Where it gets weird is actually getting the information I need. Here's an instance of a list of information I need for the project.

"Text":"Alma Gutierrez - Alma M. Gutierrez is a fictional character on the HBO drama The Wire, played by actress Michelle Paress. Gutierrez is a dedicated and idealistic young reporter on the city desk of The Baltimore Sun."

You see, the name of the character and the description is all in a single string value. I'm usually used to name and the description being separated like this for example

Text:{
      name: "Alma Gutierrez"
      description:"Alma is a..."
}

So my question is, how can I manipulate the response so that I can get the name and the description separately? I am thinking maybe some sort of function that will take the string value from the JSON call and split it to a name and description values. But I'm not sure how to do that.

I'll leave my project GitHub URL so you guys for reference. Thanks for the help.

You can use split() to split a string into parts based on a delimiter.

For instance, if you have a string containing the description as mentioned in the question, you can do the following:

val text = "Alma Gutierrez - Alma M. Gutierrez is a fictional character on the HBO drama The Wire, played by actress Michelle Paress. Gutierrez is a dedicated and idealistic young reporter on the city desk of The Baltimore Sun."

val (name, description) = text.split(" - ", limit = 2)

(see the behaviour in this playground)

The limit = 2 parameter ensures that you won't miss a part of the description if it contains - . It only splits in maximum 2 parts, so it will consider everything until the first occurrence of - as the name, and everything after that as the description, even if it includes more occurrences of - .

Note that using the deconstruction val (name, description) = ... like this will fail if split() returns less than 2 parts (in other words, it will fail if the initial text doesn't contain - at all. It may be ok for you depending on the input you expect here.

To add on to what Joffery said, I actually created a variable to hold the the spited string.

 val parts = Text.split(" - ", limit = 2)

Since there's only two values in the split, I can use the variable and call the index that I need for the corresponding text field.
