Question

我正在开发一种应用方法,其中我的一个单元是天气预报。我正在使用SAX Parser,截至现在,我正在整理XML档案,并获得一个地方的成果。

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.saxmain);
    
    ScrollView MyScrollView = new ScrollView(this);
    LinearLayout layout = new LinearLayout(this);
    
    layout.setOrientation(LinearLayout.VERTICAL);
    MyScrollView.addView(layout);
    
    try {
        
        /** Handling XML */
        SAXParserFactory spf = SAXParserFactory.newInstance();
        SAXParser sp = spf.newSAXParser();
        XMLReader xr = sp.getXMLReader();

        /** Send URL to parse XML Tags */
        URL sourceUrl = new URL(
                "http://192.168.1.31:81/Udayavani/android/weather/weather.php?city=mumbai");

        /** Create handler to handle XML Tags ( extends DefaultHandler ) */
        MyXMLHandler myXMLHandler = new MyXMLHandler();
        xr.setContentHandler(myXMLHandler);
        xr.parse(new InputSource(sourceUrl.openStream()));
        
    } catch (Exception e) {
        System.out.println("XML Pasing Excpetion = " + e);
    }

 /* Get result from MyXMLHandler TagList Object */
    taglist = MyXMLHandler.sitesList;

      
    
    for (int i = 0; i <26; i++) {
        texts[i] = new TextView(this);
        texts[i].setText(""+i);
        texts[i].setTypeface(kannada);
        layout.addView(texts[i]);
        
        
    }
    /** Set the result text in textview and add it to layout */
        texts[0].setText("Current= "+taglist.getCurrent().get(0));
        texts[1].setText("Temp= "+taglist.getTemp().get(0));
        texts[2].setText("Humidity= "+taglist.getHumidity().get(0));
        texts[3].setText(""+taglist.getWind_condition().get(0));
        texts[4].setText(""+taglist.getIcon().get(0));
       int j=0; 
       int k=5;
        while(k<20){
        texts[k].setText("----------------------------------"); 
        k++;
        texts[k].setText("Day= "+taglist.getDay().get(j));
        k++;
        texts[k].setText("Condition= "+taglist.getCondition().get(j));
        k++;
        texts[k].setText("Low= "+taglist.getLow().get(j));
        k++;
        texts[k].setText("High= "+taglist.getHigh().get(j));
        k++;
        texts[k].setText("Icon= "+taglist.getIcon().get(j));
        k++;
        j++;
        if(j>=5){
            j=0;
               }
             }
    

    /** Set the layout view to display */
    setContentView(MyScrollView);

  }
    }

我向SO提出的问题是,谁会帮助我获得各个城市的平坦Xml档案? 我几乎在所有城市都拥有URL,而且我可以认为,通过在我法典中提到的URL(例如天气.php?city=auckland)的末尾改变城市名称。我从《名单》开始,我有大约20-30个城市作为名单上的党派储存在《意见》中。每当我点击特定地点时,我就希望获得该特定城市的平坦XMl档案。

请就此向我提供指导。

Answer 1

I got the solution.I am declaring an array of places called StateNames[].And from my ListView class I am passing putExtra("id",pos) to the class where I have declared my array,and I am accessing it through the following:

String actualUrl="http://192.168.1.31:81/Udayavani/android/weather/weather.php?city=";     
private String[] StateNames={..,..,..};
//In OnCreate()
    Bundle b = getIntent().getExtras();
    id= b.getInt("id");
    String myURL=actualUrl+StateNames[id];
   try {

        /** Handling XML */
        SAXParserFactory spf = SAXParserFactory.newInstance();
        SAXParser sp = spf.newSAXParser();
        XMLReader xr = sp.getXMLReader();

        /** Send URL to parse XML Tags */
        URL sourceUrl = new URL(myURL);

        /** Create handler to handle XML Tags ( extends DefaultHandler ) */
        MyXMLHandler myXMLHandler = new MyXMLHandler();
        xr.setContentHandler(myXMLHandler);
        xr.parse(new InputSource(sourceUrl.openStream()));

    } catch (Exception e) {
        System.out.println("XML Pasing Excpetion = " + e);
    }

Answer 2

使用清单而不是浏览。采用ListItemClick()清单方法,将特定清单项目(ur case中的城市)点击,并将其作为一个参数予以通过(该参数应能将城市u的Xml档案传至村)。欲了解更多名单:
