在Android中，如何将我的setter值转换为字符串？

Question

In my activity I have sharedReview.setPhoneNumberofUserFromDB(obj.getString("username"));

It sets the value to a string from my DB and then I get that value in my adapter for use in my recyclerView , which is working ok.

In my activity how can I convert sharedReview.setPhoneNumberofUserFromDB(obj.getString("username")); to a string?

I've tried the below but it doesn't work:

String userNameAsString= String.valueOf(sharedReview.setPhoneNumberofUserFromDB(obj.getString("username")));

and

String phoneNoonPhone = (sharedReview.setPhoneNumberofUserFromDB(obj.getString("username")).toString());

It tells me the method toString can't be resolved and Cannot resolve method valueOf(void);

Answer 1

A long shot:

String phoneNoonPhone = obj.getString("username");
sharedReview.setPhoneNumberofUserFromDB(phoneNoonPhone);

In general setters return void (nothing), so you don't actually get something to assign to a variable from the return. Getters do return something. Generally for every void setFoo(Type t) there would be a Type getFoo() . In your case I'd expect a String getPhoneNumberofUserFromDB() .
