XML 구문 분석 후 스피너 값

Question

XML 구문 분석 후 스피너에 값을 표시하는 데 문제가 있습니다. XML 구문 분석을 수행했지만 이제는 구문 분석 결과를 회 전자에 표시하고 싶지만 실행하면 응용 프로그램이 강제 종료됩니다. 코드 스 니펫은 아래에 나와 있습니다.

public class parsedspinner extends Activity { 
    String name = null; 
    private String array_spinner[]; 

    /** Create Object For SiteList Class */ 
    SitesList sitesList = null; 

    /** Called when the activity is first created. */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 

    try { 


      SAXParserFactory spf = SAXParserFactory.newInstance(); 
      SAXParser sp = spf.newSAXParser(); 
      XMLReader xr = sp.getXMLReader(); 

      /** Send URL to parse XML Tags */ 
      URL sourceUrl = new URL(
        "http://www.arteonline.mobi/iphone/output.php?estado=1"); 

      /** 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 SitlesList Object */ 
     sitesList = MyXMLHandler.sitesList; 
     /** Assign textview array lenght by arraylist size */ 


     /** Set the result text in textview and add it to layout */ 
     for (int i = 0; i < sitesList.getName().size(); i++) { 

      name=sitesList.getName().get(i); 
      array_spinner=new String[sitesList.getName().size()]; 
      array_spinner[i]=name; 
      Spinner s = (Spinner) findViewById(R.id.Spinner01); 
**//till here no problem** when using array adapter then forse close.. 

      **ArrayAdapter adapter = new ArrayAdapter(this, 
      android.R.layout.simple_spinner_item, array_spinner); 
      s.setAdapter(adapter)**; 
**when i comented array adapterand set adapter above then values also show in log cat then defnetly problem in above 2 lines what is not gettig????pls help me...** 

      Log.i("array_spinner"+i,array_spinner[i]); 
     } 
}

Answer 1

당신은 당신의 for주기에서 코드를 부착

ArrayAdapter 선언과 을

• array_spinner 초기화를 제거하고 한다,

그래서 의 모든 항목에 대한 목록을 적용하지 않습니다

NullPointerException는 당신이 가지고, 그래서 한 횟수만큼 많은 항목을 초기화있어 때문에 array_spinner의 던져졌다

array_spinner = new String[sitesList.getName().size()]; 
for (int i = 0; i < sitesList.getName().size(); i++) 
{ 
    name = sitesList.getName().get(i); 
    array_spinner[i] = name; 
    Log.i("array_spinner" + i, array_spinner[i]); 
} 
Spinner s = (Spinner) findViewById(R.id.Spinner01); 
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, 
    android.R.layout.simple_spinner_item, array_spinner); 
s.setAdapter(adapter); 

그것은 단지 하나의 데이터를 포함하고 다른 위치에는 null을 가지고있었습니다.

업데이트

정말 array_spinner String 배열, 당신은 초기화, 그것을 피할 수 필요하지 않은 경우 ArrayAdapter 같이

sitesList = MyXMLHandler.sitesList; 
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, 
    R.layout.simple_spinner_item, sitesList.getName()); 
s.setAdapter(adapter); 

이 방법 당신은 전체 for 필요가 없습니다 전혀 사이클!
