java - 从 ListView 获取项目值而不调用 onItemClickListner

Question

我想做的事情:我想获取所有 List View 项目并将其发送到其他 Activity 或获取 ListView 项而不声明 onItemClickListner 当我获取列表项时，我希望它们存储到另一个列表中，并将该列表发送到其他 Activity ，我可以在其中获取所有列表项列表中的项目

问题如何获取包含多个字段的单个 ListView 项的值，即编辑文本

我在做什么

 public boolean onOptionsItemSelected(MenuItem item) {
        int id = item.getItemId();
        if (id == R.id.save_information){

            list = new ArrayList();

            for (int i =0 ; i < arrayAdapter.getCount() ; i++){

                Language_data_comes_here l = arrayAdapter.getItem(i);
                list.add(l);

            }



            Intent i = new Intent (Language_Activity.this , Selecting_Activity.class);
            i.putExtra("List" , list);
            startActivity(i);

        }
        return super.onOptionsItemSelected(item);
    }

public class Language_data_comes_here {

    private String data ;
    private int image ;

    Language_data_comes_here(int image , String data){

        this.data = data ;
    }

    public int getImage() {
        return image;
    }

    public String getLanguage() {
        return data;
    }
}

Answer 1

不知何故，我解决了这个问题

    Language_data_comes_here d = (Language_data_comes_here) listView.getAdapter().getItem(0);
