如何阅读文件以从标签之间的框中选择信息，并将其显示在我的TextView中。

Answer 1

你可以尝试类似的东西：

            // Get your file from internet
    URL url = new URL("http://url.com/info.xsl");
    URLConnection connection = url.openConnection();
    InputStream in = connection.getInputStream();
    String filePath = Environment.getExternalStorageDirectory().getAbsolutePath()+ "/filename.xml"
    File file = new File (filePath);

    CreateFileFromInputStream(in,  filePath) ;

            // Parse it with document builder factory
    DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
    DocumentBuilder dBuilder = null;
    dBuilder = dbFactory.newDocumentBuilder();
    Document doc = null;
    doc = dBuilder.parse(file);
    doc.getDocumentElement().normalize();
    // The root element is 
    doc.getDocumentElement().getNodeName();

    NodeList nList =    doc.getElementsByTagName("Name");

    for ( int i = 0 ; i < nList.getLength() ; i++ ) {

        Element element = (Element) nList.item(i) ;
        String name = getCharacterDataFromElement(element);

    }

with：

public static String getCharacterDataFromElement(Element e)
{
    Node node = e.getFirstChild();
    if (node instanceof CharacterData)
    {
        CharacterData cd = (CharacterData) node;
        return cd.getData();
    }
    return "";
}

和：

public void CreateFileFromInputStream(InputStream inStream, String path) throws IOException {
    // write the inputStream to a FileOutputStream
    OutputStream out = new FileOutputStream(new File(path));

    int read = 0;
    byte[] bytes = new byte[1024];

    while ((read = inStream.read(bytes)) != -1) {
        out.write(bytes, 0, read);
    }

    inStream.close();
    out.flush();
    out.close();

}

我希望它有所帮助...
