如何在JSON字符串中用大括号替换大括号？

Question

I'm developing an Android project. In development I use Retrofit, Gson, RxJava.

For example, such an answer may return from my server and I must replace the curly braces with real values.

{
    "text": "Hello {0} World {1} This is {2} test text"
}

You can use MessageFormat like so:

import java.text.MessageFormat;
MessageFormat.format("Hello {0} World {1} This is {2} test text", var1, var2, var3)
