通过 HTTP 解析 XML 时出错

发布于 2024-10-27 07:22:45 字数 12174 浏览 1 评论 0原文

在此给定的代码中，我的 HTTP 相关代码工作正常，并且在 toast 消息中给出了正确的结果。但是，当我应用 HTTP 内容 (XML) 解析时，它将强制关闭。

我在这里所做的具体问题是什么？

public class Player extends Activity {

    String d="";
    TextView id[];
    TextView name[];
     String str;
    TableLayout t1;
    private HttpEntity responseEntity;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState); 
        setContentView(R.layout.player);

        TableLayout t1 = (TableLayout) findViewById(R.id.myTable);

       Intent i = getIntent();
        Bundle b = i.getExtras();
        String str = b.getString("ARRIVING_FROM");

        TextView title = (TextView) findViewById(R.id.TextView01);
        title.setText(str);

            d=d+"";
            d = tryLogin(str);
            System.out.println("Value of D"+d.substring(0, 1));
            if(d.substring(0, 1).equalsIgnoreCase("1"))
            //if(d.equals(str))
            {

                Toast.makeText(getApplicationContext(), "OOPS", Toast.LENGTH_SHORT).show();
            }
    else
        Toast.makeText(getApplicationContext(), d, Toast.LENGTH_SHORT).show();

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

            XMLHandler myXMLHandler = new XMLHandler();
            xr.setContentHandler(myXMLHandler);
            xr.parse(retrieveInputStream(responseEntity));
            } catch (Exception e) {
                System.out.println("XML Parsing Excpetion = " + e);
        }


        final ScoreList scorelist = XMLHandler.scorelist ;

        id = new TextView[scorelist.getName().size()];
        name = new TextView[scorelist.getName().size()];

        for (int i1 = 0; i1 < scorelist.getName().size(); i1++) {

            TableRow tr = new TableRow(this);
            tr.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT)); 

             id[i1]= new TextView(this);
             id[i1].setText(scorelist.getId().get(i1));
             id[i1].setTextColor(Color.WHITE);
             id[i1].setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT));

             tr.addView(id[i1]);

             name[i1]= new TextView(this);
             name[i1].setText(scorelist.getName().get(i1));
             name[i1].setTextColor(Color.WHITE);
             name[i1].setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT));
             tr.addView(name[i1]);


             t1.addView(tr, new TableLayout.LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT));  
        }
   }  

                private InputSource retrieveInputStream(HttpEntity responseEntity) {

In this given code, my HTTP-related code is working correctly and it is giving correct result in toast message. However when I apply parsing of the HTTP content (XML), it will force close.

What is the exact problem with what I'm doing here?

public class Player extends Activity {

    String d="";
    TextView id[];
    TextView name[];
     String str;
    TableLayout t1;
    private HttpEntity responseEntity;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState); 
        setContentView(R.layout.player);

        TableLayout t1 = (TableLayout) findViewById(R.id.myTable);

       Intent i = getIntent();
        Bundle b = i.getExtras();
        String str = b.getString("ARRIVING_FROM");

        TextView title = (TextView) findViewById(R.id.TextView01);
        title.setText(str);

            d=d+"";
            d = tryLogin(str);
            System.out.println("Value of D"+d.substring(0, 1));
            if(d.substring(0, 1).equalsIgnoreCase("1"))
            //if(d.equals(str))
            {

                Toast.makeText(getApplicationContext(), "OOPS", Toast.LENGTH_SHORT).show();
            }
    else

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

            XMLHandler myXMLHandler = new XMLHandler();
            xr.setContentHandler(myXMLHandler);
            xr.parse(retrieveInputStream(responseEntity));
            } catch (Exception e) {
                System.out.println("XML Parsing Excpetion = " + e);
        }

             id[i1].setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT));

您在 MyPlayerInfo 第 91 行的 onCreate() 方法中出现了 NullPointerException。

另外，切勿在主应用程序线程上进行网络 I/O 和解析。请使用 AsyncTask 或其他形式的后台线程。

You have a NullPointerException on line 91 of MyPlayerInfo, in the onCreate() method.

Also, never do network I/O and parsing on the main application thread. Use an AsyncTask or some other form of background thread, please.
