在Android的TextView中显示分数？

我正在研究android测验。我在QuestionActivity类中有setQuestion（）方法。我在其中我创建TextView来显示分数的question.xml中。我想在setQuestion中编写代码，以使其具有得分的按钮的设置TextView。基本上我的得分是从GamePlay类的getScore（）方法中检索的，并且得分是用正确或错误的答案来更新的。就像在setQuestion（）方法中一样，我的下一个问题答案TextView在下一轮更新。

public class GamePlay {

    private int numRounds;
    private int difficulty;
    private int score;
    private int round;

    private List<Question> questions = new ArrayList<Question>();


    /**
     * @return the right
     */
    public int getScore() {
        return score;
    }
    /**
     * @param right the right to set
     */
    public void setScore(int score) {
        this.score = score;
    }

    /**
     * @return the round
     */
    public int getRound() {
        return round;
    }
    /**
     * @param round the round to set
     */
    public void setRound(int round) {
        this.round = round;
    }
    /**
     * @param difficulty the difficulty to set
     */
    public void setDifficulty(int difficulty) {
        this.difficulty = difficulty;
    }
    /**
     * @return the difficulty
     */
    public int getDifficulty() {
        return difficulty;
    }
    /**
     * @param questions the questions to set
     */
    public void setQuestions(List<Question> questions) {
        this.questions = questions;
    }

    /**
     * @param q the question to add
     */
    public void addQuestions(Question q) {
        this.questions.add(q);
    }

    /**
     * @return the questions
     */
    public List<Question> getQuestions() {
        return questions;
    }


    public Question getNextQuestion(){

        //get the question
        Question next = questions.get(this.getRound());
        //update the round number to the next round
        this.setRound(this.getRound()+1);
        return next;
    }

    /**
     * method to increment the number of correct answers this game
     */


    /**
     * method to increment the number of incorrect answers this game
     */
    public void incrementScore(){
        score=score+100;
    }

    public void decrementScore()
    {
        score=score-50;
    }
    /**
     * @param numRounds the numRounds to set
     */
    public void setNumRounds(int numRounds) {
        this.numRounds = numRounds;
    }
    /**
     * @return the numRounds
     */
    public int getNumRounds() {
        return numRounds;
    }

    /**
     * method that checks if the game is over
     * @return boolean
     */
    public boolean isGameOver(){
        return (getRound() >= getNumRounds());
    }
