自动生成app架构设计【一】

 

 

 

1、管理数据对象

 包括获取数据，提交数据

public class WebDateSet{     private HashMap paramList = null; //参数列表   private String serverUrl = null; //地址     public WebDateSet(String paramString)   {     this.serverUrl = paramString;     this.paramList = new HashMap();   } publicvoid addParam(String param1, String param2)   {      this.paramList.put(param1, param2);//添加参数   } //获取数据get public List<HashMap> getDateSet(Context paramContext..){   String path = this.serverUrl + "?test=1"; //for循环上面的paramList{ path  =path + "&" + str2 + "=" + str3; } 如果没有网络，从安卓数据库里面取 //表结构：CREATE TABLE datacache (key Text, data Text);                             if (paramInt == 0) { //无网咯                                      String xml = new DataCache(paramContext).readCache(path); //db.rawQuery("select * from datacache where key=?"             }else{ 如果有网络，从HttpURLConnection取 dataSet = miijiaoXML.ParserXml(result); //解析获取的          new DataCache(paramContext).writeCache(path, result);//放到数据库 } }

返回的数据格式为：

list = new ArrayList<HashMap>();

if("item".equals(pullParser.getName())){

         map = new HashMap<String,String>();

map.put("title", pullParser.nextText()); list.add(map) //1个item就是1个hashmap

 

2、显示类：

publicclass helloworld extends Activity {   publicvoid onCreate(Bundle paramBundle)   {     super.onCreate(paramBundle);     setContentView(R.layout.show);       HelloContent content = new HelloContent(this, http://baidu.com/, "app_getHellworld.php");     content.addUrlParam("userid", 1);//get请求的参数,只有这1个 content.addContentItemByImageUrl(R.id.image, "image"); //要显示的id，及上面值对应的key     content.addContentItemByText(R.id.title, "title");     content.addContentItemByHtmlText(R.id.content, "content");     content.view();   } }

 

 

3、处理类：

publicclass HelloContent {   public ArticleContent(Activity acitvity, String param1, String param2)   {     this.activity = acitvity;     this.webUrl = (param1+ "/" + param2);     this.wds = new WebDateSet(this.webUrl);   }   //添加请求参数   publicvoid addUrlParam(String paramString1, String paramString2)   {     this.wds.addParam(paramString1, paramString2);   }    //添加显示的控件   publicvoid addContentItemByText(int paramInt, String paramString)   {     HashMap localHashMap = new HashMap();     localHashMap.put("itemType", "TextView");     localHashMap.put("dataSetItemName", paramString);     this.itemList.put(Integer.valueOf(paramInt), localHashMap);   }     publicvoid addContentItemByImageUrl(int paramInt, String paramString)   {     HashMap localHashMap = new HashMap();     localHashMap.put("itemType", "ImageViewUrl");     localHashMap.put("dataSetItemName", paramString);     this.itemList.put(Integer.valueOf(paramInt), localHashMap);   }  ……其他的同上面的类似 itemList数据格式为: [R.id.text1:[itemType:TextView,dataSetItemName:title]]     publicvoid view()   {     List localList = this.wds.getDateSet(this.activity, this.netState);           this.contentData = ((HashMap)localList.get(0));       showItem(); }    }   privatevoid showItem()   { Iterator item = this.itemList.entrySet().iterator();       for迭代所有的       String key = item.next().getKey();            HashMap map = (HashMap) item.next().getValue();       String str1 = (String)map.get("itemType");       String str2 = (String)map.get("dataSetItemName");       if ("TextView".equals(str1))       {         TextView tt =(TextView)this.activity.findViewById(key);         tt.setText((String)this.contentData.get(str2));    } } }
