自动生成app架构设计【二】listview设计

上面只是单个页面，下面实现列表页面的逻辑

publicclass HellwordActivity extends Activity {   protectedvoid onCreate(Bundle paramBundle)   {     super.onCreate(paramBundle);     setContentView(R.layout.show_list);       HellwordList list = new HellwordList(this, R.id.listView, R.layout.show_item, url, 20);     list.addUrlParam("userid", 11111);     list.addUrlParam("type", "1");     list.addAdapterItemByText(R.id.title, "title");     list.addAdapterItemByText(R.id.phone, "phone");     list.addAdapterItemByText(R.id.address, "address");     list.view();   } }

 

4.2、处理

publicclass HellwordList {       public HellwordList(Activity activity, int listviewid, int showitemid, String url, int page)   {     this.activity = activity;     this.pageNum = page;     this.wds = new WebDateSet(url); this.listView = ((ListView)activity.findViewById(listviewid)); this.listAdapter = new ListAdapter(activity, this.listData, showitemid); }     publicvoid addAdapterItemByText(int paramInt, String paramString)   {     this.listAdapter.addText(paramInt, paramString);   }   publicvoid view()   {     this.listData = this.wds.getDateSet(…); this.listView.setAdapter(this.listAdapter); this.listAdapter.appendDataSet(this.listData); } }

4.3、Adapter

private Map<Integer, View> viewMap = new HashMap();

  public View getView(int paramInt, View paramView, ViewGroup paramViewGroup)

  {

View localView = (View)this.viewMap.get(Integer.valueOf(paramInt));

如果为空就创建，否则直接从map从返回.

创建后添加的内容同单个页面。
