android - 显示测验应用的结果 (Android Studio)

Question

我有一个可以正常运行的测验应用程序，但问题是用户必须正确回答所有问题才能赢得游戏（如果玩家弄错了游戏将结束）。

我想做的是回答问题，然后最后会有一个活动显示玩家回答了多少，然后会有重试选项并返回菜单

这是 maingameactivity 的代码

只需删除if else所有按钮内的包装更好地保留它，不要重复代码。我假设显示结果的屏幕是在内部处理的，gameWon并且您已经实现了以下功能inCorrectDialog

public void buttonA(View view) {
 Button button = (Button) view;
 buttonPressed(button);
}
public void buttonB(View view) {
 Button button = (Button) view;
 buttonPressed(button);
}

public void buttonC(View view) {
 Button button = (Button) view;
 buttonPressed(button);
}

public void buttonD(View view) {
 Button button = (Button) view;
 buttonPressed(button);
}

public void buttonPressed(Button button) {

 button.setButtonColor(ContextCompat.getColor(getApplicationContext(), R.color.lightGreen));
 if (qid < list.size() - 1) {
  disableButton();
  if (currentQuestion.getOptA().equals(currentQuestion.getAnswer())) {
   correctDialog();
  } else {
   inCorrectDialog();
  }

 } else {
  gameWon();
 }

}
