如何在listview里面的listview中实现onClicklistener移动到下一个片段

Question

以下是我的代码，我使用包含文本和图片的listview填充我的片段。 我想知道，当从listview项目中单击项目时，如何移动到下一个片段。 例如，如果单击第一个项目将打开片段A，如果单击第二个项目将打开片段B。

我使用以下作为解决方案，但它不起作用。

任何帮助都将得到很高的评价。

我试图添加公共类俱乐部扩展Fragment实现OnItemClickListener但它抛出我的错误，类必须声明为抽象..

任何帮助都将受到高度赞赏。

Answer 1

试试这个

listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> arg0, View view, int position, long arg3) {
      //Your click code here. 
    }
});

OR

listView.setOnItemClickListener(itemClickListener);

因为您已经在班级中定义了 itemClickListener 。
