6.2生词本管理模块的实现

生词本管理模块是提供用户管理自己创建生词本的功能的模块，在用户添加了生词本之后就可以将生词放入生词本中了，图6.3是生词本模块的界面，图6.4,是添加生词本界面，图6.5删除生词本界面，在点击查询显示页面的添加图标后，可以讲单词添加至生词本中图6.6是将单词添加至生词本的界面：

图6.3生词本模块界面

生词本界面实现代码如下：

public class NotesFragment extends Fragment { private ImageButton btn_update; private ImageButton btn_add; private ListView notelistview; private List notestalist; //复杂数据形式作为数据源 ArrayList> listItem = new ArrayList>(); private View NoteLayout; @Override public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) { Log.i(\第三个fragment\ NoteLayout = inflater.inflate(R.layout.fragment_notes, container, false); Init(NoteLayout); return NoteLayout; } public void Init(View v) { btn_update=(ImageButton)v.findViewById(R.id.btn_update); btn_add = (ImageButton) v.findViewById(R.id.btn_add); notelistview = (ListView) v.findViewById(R.id.noteListview); btn_add.setOnClickListener(new AddListener()); //将当前生词本和每个生词本中包含的单词数量使用listview显示出来的线程 Thread nt=new notesThread(); nt.start();

// 生成适配器的Item和动态数组对应的元素 //使用简单适配器来作为listview的适配器

};

public class AddListener implements OnClickListener {
