Migrate String from Java class to resources

Issue

I working in a Quiz Question.

I have on "Questions.java"

package com.example.luisbalmant.quickquiz_science;

import android.widget.TextView;

/**

 */

public class Questions {
    public String mQuestions[] = {
            "My question here",


    };
}

I'm trying use string language of "strings.xml" on "My question here".

Eg:

<string name="Q1_function_insulin">What is the function of insulin?</string>

I'm trying this:

getString(R.string.Q1_function_insulin),

Can someone help me please?

Solution

You need a Context object in order to perform getString(). Thus, you can refactor your class this way:

    public class Questions {

        private static final int QUESTIONS[] = {
                R.string.text1,
                R.string.text2
        };

        private Context context;

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

        public String getString(int index) {
            return context.getString(QUESTIONS[index]);
        }
    }

And then, from your activity:

Questions questions = new Questions(MainActivity.this);
questions.getString(0);
