Android 将简单的Listview程序转换为Listview的XML解析器 我正在将ListVIEW示例转换成一个程序，该程序通过读取XML文件来运行，然后填充具有内容的列表视图。但我似乎遇到了一个障碍。我不知道如何使用我为第一个示例制作的适配器，以及如何在这个新程序中使用它，任何指针都将不胜感激。 这是主要的 Phonebook phonebook = null; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); ListView list = (ListView) findViewById(R.id.ListView01); list.setClickable(true); final List<Phonebook> listOfPhonebook = new ArrayList<Phonebook>(); PhonebookAdapterView adapter = new PhonebookAdapterView(this, listOfPhonebook); list.setAdapter(adapter); try { /** Handling XML */ SAXParserFactory spf = SAXParserFactory.newInstance(); SAXParser sp = spf.newSAXParser(); XMLReader xr = sp.getXMLReader(); /** Send URL to parse XML Tags */ InputSource is = new InputSource(getResources().openRawResource(R.raw.example)); /** Create handler to handle XML Tags ( extends DefaultHandler ) */ MyXMLHandler myXMLHandler = new MyXMLHandler(); xr.setContentHandler(myXMLHandler); xr.parse(new InputSource(is.getByteStream())); } catch (Exception e) { System.out.println("XML Parsing Exception = " + e); } phonebook = MyXMLHandler.phonebook; list.setAdapter(adapter); Phonebook-Phonebook=null； /**在首次创建活动时调用*/ @凌驾 创建时的公共void（Bundle savedInstanceState）{ super.onCreate（savedInstanceState）； setContentView（R.layout.main）； ListView列表=（ListView）findViewById（R.id.ListView01）； list.setClickable（true）； PhoneBook的最终列表列表=新的ArrayList（）； PhonebookAdapterView adapter=新的PhonebookAdapterView（此，电话簿列表）； list.setAdapter（适配器）； 试一试{ /**处理XML*/ SAXParserFactory spf=SAXParserFactory.newInstance（）； SAXParser sp=spf.newSAXParser（）； XMLReader xr=sp.getXMLReader（）； /**发送URL以解析XML标记*/ InputSource is=新的InputSource（getResources（）.openRawResource（R.raw.example））； /**创建处理XML标记的处理程序（扩展DefaultHandler）*/ MyXMLHandler MyXMLHandler=新的MyXMLHandler（）； xr.setContentHandler（myXMLHandler）； parse（新的InputSource（is.getByTestStream（））； }捕获（例外e）{ System.out.println（“XML解析异常=”+e）； } phonebook=MyXMLHandler.phonebook； list.setAdapter（适配器）；
