Android Studio – How to get parameter values in string.xml from MainActivity?

This is my MainActivity.java.

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        String myString = "Mary";
        int myInt = 12;
        String formatted = getString(R.string.my_xml_string, myString, myInt);

    }
}

string.xml

<resources>
    <string name="app_name">My First App</string>
    <string name="my_xml_string">My sister %1$s is %2$d years old.</string>
</resources>

However when I run the app,I still got ‘My sister %1$s is %2$d years old.’ as text. Anyone knows why?

On the side note, it says the variable formatted is not used. So how does that link to the string.xml file?

    In case anyone is facing the same issue, I use

    #setText to pass value
RandomGeneratedNumber = (TextView)findViewById(R.id.random);
RandomGeneratedNumber.setText(random_generated_number);

    Try this

    String mString = getString(R.string.hello);

    or

    String mString= getResources().getString(R.string.hello);
