我如何从一个活动中检索int数据并将其设置为另一活动的textView

Question

发送课程代码：

Intent i = new Intent(this, QuizActivity.class);
        i.putExtra("name", name);
        startActivity(i);

正在接收课程代码：

Intent intent = getIntent();
    if (intent != null) {
        totalScore = intent.getIntExtra("totalScore",0);
    }
    TextView scoreView = findViewById(R.id.totalScore);
    scoreView.setText(totalScore);

Answer 1

在发送方，使用Intent.putExtra：

Intent myIntent = new Intent(A.this, B.class);
myIntent.putExtra("totalScore", intValue);
startActivity(myIntent);

在接收方，使用Intent.getIntExtra：

 Intent mIntent = getIntent();
 int totalScore = mIntent.getIntExtra("totalScore", 0);
 TextView scoreView = findViewById(R.id.totalScore);
 scoreView.setText(totalScore+"");
