Question

我正在android studio上开发简单的游戏，你需要识别给定的图像。每张图片有40分，但每次你回答错误时，你的40分将被扣除10分。积分将累积，直到您完成识别10张图片。我的问题是，我不知道如何将积分传递给另一个活动，以便我可以添加它。这是我的Java代码.. PS。抱歉，我在android studio和StackOverflow中都是新手，我不知道如何撰写问题。

    public void onClickSubmit (View view) {

        answer = (EditText) findViewById(R.id.etAnswer);
        tvResult = (TextView) findViewById(R.id.resultLabel);

        if (answer.getText().toString().equals("apple")) {
            Intent intent = new Intent(this, appleTrivia.class);
            startActivity(intent);
            tvResult.setText("Good eye sight");
            tvResult.setTextColor(0xFF00FF00);
            timer.cancel();
            totalScorePoints = scorePoints;

            String result = String.valueOf(totalScorePoints);
            pointsLabel.setText("Score: " + result);
            answer.setText("");



        } else {
            tvResult.setText("No no no. try again.");
            tvResult.setTextColor(0xFFFF0011);
            answer.setText("");
            scorePoints = scorePoints - minusPoint;
            totalScorePoints = scorePoints;
            String result = String.valueOf(totalScorePoints);
            pointsLabel.setText("Score: " + result);

如何将totalScorePoint传递给我的第二个活动，以便将第一个活动的点数添加到第二个活动的点数。 tnx将响应我的noob问题^ _ ^这是我的第二个活动.enter code here here public void onClickSubmit（查看视图）{

    answer = (EditText) findViewById(R.id.etAnswer);
    tvResult = (TextView) findViewById(R.id.resultLabel);

    if (answer.getText().toString().equals("cherry")) {
        Intent intent = new Intent(this, cherryTrivia.class);
        startActivity(intent);
        tvResult.setText("Good eye sight");
        tvResult.setTextColor(0xFF00FF00);
        timer.cancel();

        totalScorePoints = scorePoints;

        String result = String.valueOf(totalScorePoints);
        pointsLabel.setText("Score: " + result);
        answer.setText("");
    } else {
        tvResult.setText("No no no. try again.");
        tvResult.setTextColor(0xFFFF0011);
        answer.setText("");
        scorePoints = scorePoints - minusPoint;
        totalScorePoints = scorePoints;
        String result = String.valueOf(totalScorePoints);
        pointsLabel.setText("Score: " + result);



    }
}
}

在发送方：

Intent intent = new Intent(this, cherryTrivia.class);
intent.putExtra( "points", scorePoints );
startActivity(intent);

在接收方：

getIntent().getIntExtra( "points", 0 );
