GlobalClass

class GlobalClass extends Application {
     public static String[] myval;
}

HomeActivity

将内容添加到 ListView，然后对每个 ListItem 值使用 onItemClickListener。您可以通过以下代码实现您的目标。

使用它作为全局变量而不是字符串数组

全球级

 class GlobalClass extends Application {
 public static List<String> myVal = new ArrayList<String>() ;
 }

主页活动

OnItemClickListener

   listView.setOnItemClickListener(new OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position,
                long id) {

             String clickedvalue =(String) parent.getItemAtPosition(position); 
             myVal.add(clickedvalue);

             }
        }); 
    }

现在所有单击的值都将位于您的 ListArray 中。

我希望它有帮助。
