java – Problems using string for resources

Question:

I'm creating a quiz app, the link is https://github.com/luisbalmant/QuickQuiz-Science .

I'm trying to use getString(R.string.nome) to migrate strings from java class and then be able to use 2 languages.

In other places I managed to pull the strings and it's working showing the texts when I run the app on my cell phone, but the moment I try to use the string in the questions the app just doesn't open anymore.

public class Questions {

        public String mQuestions[] = {

// Funciona
                "Pergunta número 1 xxxxxxx",

// NÃO FUNCIONA
                getString(R.string.Q1_function_insulin),

        };

==/=/=/=/=/=/=/=/=/=/=/=/=/=/=/=/=//=/=/=/=/=/=/= /=

Update:

I made the following changes and it didn't work:

My MainActivity.java:

public class MainActivity extends AppCompatActivity {

    Button answer1, answer2, answer3;

    TextView score, question;

    private Questions mQuestions;

    private String mAnswer;
    private int mScore = 0;
    private int mQuestionsLength;

    Random r;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mQuestions = new Questions(this);
        mQuestionsLength = mQuestions.mQuestions.length;

        r = new Random();

My other Questions.java file

import android.content.Context;

public class Questions extends MainActivity {

    Context context;
    public Questions(Context context)
    {
        this.context = context;
    }

    public String mQuestions[] = {

            "Pergunta número 1 xxxxxxx",
            context.getString(R.string.Q1_function_insulin),
            "Outra Pergunta número 2",

    };

Answer:

Try it this way:

public class Questions {

    private Context context;
    private Integer[] mQuestions = new Integer[]{R.string.Q1_function_insulin, R.string.Q2_any_name};

    public Questions(Context context) {

        this.context = context;
    }

    public String get(int q_number) {
        String question = null;
        try {
            question = context.getString(mQuestions[q_number - 1]);
        } catch (IndexOutOfBoundsException e) {
            Log.e("Question", "Invalid question number: " + q_number);
        }
        return question;
    }
}

Em OnCreate declare a classe Questions:

Questions mQuestions = new Questions(this);

Get the questions:

String question1 = mQuestions.get(1); //obtém a questão 1 e assim por diante...
