Question

我正在尝试设置一系列检查按钮，点击这些按钮会将链接到这些按钮的变量值设置为1。 “运行”按钮仅运行选中了“检查”按钮的检查。全局变量值例如：单击按钮时不会更新check_H1。

在运行脚本时，感觉有很多东西不能像我想的那样工作。我改变了一些东西，并从按钮命令中删除了变量，因为变量被传递给要在开始时运行的命令而不是按下按钮的位置。

我还删除了所有public class HomeActivity2 extends AppCompatActivity { public ViewPagerAdapter adapter; private Toolbar toolbar; private TabLayout tabLayout; private NonSwipeableViewPager viewPager; public ArrayList<String> mappingOfCategoryWithIndex = new ArrayList<>(); public ArrayList<MenuItem> allMenuItemsList = new ArrayList<MenuItem>(); ArrayList<MenuItemCategory> allMenuItemCategoryList = new ArrayList<MenuItemCategory>(); //Getters public NonSwipeableViewPager getViewPager() { return viewPager;

} }`因为它们强制将checkbutton强制为单个状态。也就是说，我没有触及任何其他功能。
