一旦点击列表项,我们如何修改手机号码？

Answer 1

在方法中onItemClick()获取与PhoneBook单击的行的位置(位置参数)对应的元素,更新该值,然后通过调用方法通知适配器数据已更改notifyDataSetChanged():

list.setOnItemClickListener(new OnItemClickListener() {

            @Override
            public void onItemClick(AdapterView<?> arg0, View view, int position, long index) {
                // make the adapter a field in your class (or final)
                PhoneBook element = (PhoneBook) adapter.getItem(position);
                //modify the PhoneBook element
                element.setPhone("555-555-555");
                // notify the adapter that something has changed
                adapter.notifyDataSetChanged();
                showToast(listOfPhonebook.get(position).getName());
            }
        });
