How to use string resource in a Java class in Android?

Issue

In my Java class I want to use a string resource from strings.xml.

For that I want to use something like this:

getString(R.string.address)

If my class is an activity then it's working.
But how can I use it if my class is a simple Java class?

Solution

A class does not have a context and to use a string resource a context is needed. So just call the class from an activity and give a parameter context and within your class constructor just use that context to get the string resource.

In your custom class you need to import the R namespace for the project to get the resource Id.

import com.myrandomapp.R;

Then to get the actual string

context.getString(R.string.COOL_STRING)
