我尝试设置TextView时应用程序崩溃

我有这个课程,我将这个名字命名为Scoreboard:

public class Scoreboard {
private int mScore = 0;
private int mHighScore = 0;

public void addPoint() {
    mScore += 1;
}

public int getHighScore() {
    return mHighScore;
}

public void setHighScore(int highScore) {
    mHighScore = highScore;
}

public int getScore() {
    return mScore;
}

public void setScore(int score) {
    mScore = score;
}

}

我有一段代码在我的活动中,每当用户将球传递到矩形的间隙时操纵这个类,并相应地更改TextView以向用户显示分数:

//Keeps track of score
            if (rectWhite1.getTheRight() > Math.round(mBallPos.x) - 5 && rectWhite1.getTheRight() < Math.round(mBallPos.x) + 5) {
                runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        mScoreboard.addPoint();
                        scoreTextView.setText(mScoreboard.getScore());

                    }
                });
                Log.d(TAG, "If statement has been run3333!!!");
            }

            if (rectWhite2.getTheRight() > Math.round(mBallPos.x) - 5 && rectWhite2.getTheRight() < Math.round(mBallPos.x) + 5) {
                runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        mScoreboard.addPoint();
                        scoreTextView.setText(mScoreboard.getScore());
                    }
                });

                Log.d(TAG, "If statement has been run2222!!!");
            }

            if (rectWhite3.getTheRight() > Math.round(mBallPos.x) - 5 && rectWhite3.getTheRight() < Math.round(mBallPos.x) + 5) {
                runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        mScoreboard.addPoint();
                        scoreTextView.setText(mScoreboard.getScore());
                    }
                });

                Log.d(TAG, "If statement has been run1111!!!");
            }

每当我运行应用程序时,只要我尝试使用与我制作的记分板类相关的任何方法,它就会崩溃。当我尝试添加一个点时它会崩溃,当我试图获得当前分数时它会崩溃,等等。所以我的问题是如何避免这种情况发生并动态改变分数?
