java - android:tableview中的xml解析输出

Question

我是安卓新手。我已经搜索了代码并完成了 xml 解析，但它在 ListView 中......我需要它应该在表格 View 中请帮我...我的代码如下:

class MyXMLHandler

import org.xml.sax.Attributes;
import org.xml.sax.SAXException;
import org.xml.sax.helpers.DefaultHandler;

public class MyXMLHandler extends DefaultHandler {

Boolean currentElement = false;
String currentValue = null;
public static SitesList sitesList = null;

public static SitesList getSitesList() {
    return sitesList;
}

public static void setSitesList(SitesList sitesList) {
    MyXMLHandler.sitesList = sitesList;
}

/** Called when tag starts ( ex:- <name>AndroidPeople</name>
 * -- <name> )*/
@Override
public void startElement(String uri, String localName, String qName, Attributes attributes) throws SAXException {

    currentElement = true;

    if (localName.equals("maintag"))
    {
        /** Start */
        sitesList = new SitesList();
    } else if (localName.equals("website")) {
        /** Get attribute value */
       // String attr = attributes.getValue("category");
       // sitesList.setCategory(attr);
    }

    }

    /** Called when tag closing ( ex:- <name>AndroidPeople</name>
 * -- </name> )*/
    @Override
    public void endElement(String uri, String localName, String qName)
            throws SAXException {

    currentElement = false;

    /** set value */
        if (localName.equalsIgnoreCase("name"))
            sitesList.setName(currentValue);
        else if (localName.equalsIgnoreCase("website"))
            sitesList.setWebsite(currentValue);

    }

/** Called to get tag characters ( ex:- <name>AndroidPeople</name>
     * -- to get AndroidPeople Character ) */
    @Override
    public void characters(char[] ch, int start, int length)
            throws SAXException {

        if (currentElement) {
            currentValue = new String(ch, start, length);
            currentElement = false;
        }

    }

}

二级站点列表

import java.util.ArrayList;

/** Contains getter and setter method for variables  */
public class SitesList {

    /** Variables */
    private ArrayList<String> name = new ArrayList<String>();
    private ArrayList<String> website = new ArrayList<String>();
  //  private ArrayList<String> category = new ArrayList<String>();

    /** In Setter method default it will return arraylist
     *  change that to add  */

    public ArrayList<String> getName() {
        return name;
    }

    public void setName(String name) {
        this.name.add(name);
    }

    public ArrayList<String> getWebsite() {
        return website;
    }

    public void setWebsite(String website) {
        this.website.add(website);
    }

  /**public ArrayList<String> getCategory() {
        return category;
   }

    public void setCategory(String category) {
        this.category.add(category);
   }**/

}

第三类是 MyParsingExample

import java.net.URL;
import javax.xml.parsers.SAXParser;
import javax.xml.parsers.SAXParserFactory;
import org.xml.sax.InputSource;
import org.xml.sax.XMLReader;
import android.app.Activity;
import android.os.Bundle;
import android.widget.LinearLayout;
import android.widget.TextView;

public class XMLParsingExample extends Activity {

/** 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);

    /** Create a new layout to display the view */
    LinearLayout layout = new LinearLayout(this);
    layout.setOrientation(1);

    /** Create a new textview array to display the results */
    TextView name[];
    TextView website[];
    //TextView category[];

    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://ipaddress/test/file.xml");

        /** 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 */
    name = new TextView[sitesList.getName().size()];
    website = new TextView[sitesList.getName().size()];
   //category = new TextView[sitesList.getName().size()];

    /** Set the result text in textview and add it to layout */
    for (int i = 0; i < sitesList.getName().size(); i++) {
        name[i] = new TextView(this);
        name[i].setText("Name = "+sitesList.getName().get(i));
        website[i] = new TextView(this);
        website[i].setText("Website = "+sitesList.getWebsite().get(i));
        /**category[i] = new TextView(this);
        category[i].setText("Website Category = "+sitesList.getCategory().get(i));**/

        layout.addView(name[i]);
        layout.addView(website[i]);
        //layout.addView(category[i]);
    }

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

}

xml 文件是

<maintag>
<!-- Table item -->
<item>
  <name>sam</name>
  <website>sam</website>
</item>

好的呃 Chaaanleeenge 已接受

我想我能猜到你想做什么。首先，您的代码基本上执行以下操作:

• 解析您的 XML 文件并将结果放入 SitesList
• 以编程方式创建所有布局内容
• 对于已解析的每个 Item，它都会生成一个新的 TextView

所以那里没有ListView。

您现在想要将解析后的值放入 TableView 中。所以我想说的是，构建生成布局的代码的方式并不是让演示内容远离代码的最佳方法。 Android 正是为此目的而精心设计的。您应该仔细查看http://developer.android.com/guide/topics/resources/index.html特别是布局资源。您可以在 xml 文件中进行布局。

回到你当前的问题。要在表格中显示您的内容，您必须编辑 MyParsingExample Activity 。

(我目前无法测试代码，但它应该按如下方式工作:)

/** Create a new layout to display the view */
LinearLayout layout = new LinearLayout(this);
layout.setOrientation(1);

此时您应该使用像这样的TableLayout:

/** Create a new layout to display the view */
TableLayout layout = new TableLayout(this);

所以 tableLayout 只是布局其他组件的另一种方式。

现在您需要看一下这部分:

/** Assign textview array lenght by arraylist size */
name = new TextView[sitesList.getName().size()];
website = new TextView[sitesList.getName().size()];
//category = new TextView[sitesList.getName().size()];

/** Set the result text in textview and add it to layout */
for (int i = 0; i < sitesList.getName().size(); i++) {
    name[i] = new TextView(this);
    name[i].setText("Name = "+sitesList.getName().get(i));
    website[i] = new TextView(this);
    website[i].setText("Website = "+sitesList.getWebsite().get(i));
    /**category[i] = new TextView(this);
    category[i].setText("Website Category = "+sitesList.getCategory().get(i));**/

    layout.addView(name[i]);
    layout.addView(website[i]);
    //layout.addView(category[i]);
}

这就是生成 Textview 的点。您需要用一些在 TableView 中生成行的代码来替换它。正如我所说，我目前无法测试代码。但我指的是:

http://developer.android.com/reference/android/widget/TableLayout.html和 http://developer.android.com/reference/android/widget/TableRow.html

例如这样:

/** Assign textview array lenght by arraylist size */
name = new TextView[sitesList.getName().size()];
website = new TextView[sitesList.getName().size()];
//category = new TextView[sitesList.getName().size()];

/** Add rows for every entry and add it to layout */
for (int i = 0; i < sitesList.getName().size(); i++) {
    //we can leave that part as it is
    name[i] = new TextView(this);
    name[i].setText("Name = "+sitesList.getName().get(i));

    website[i] = new TextView(this);
    website[i].setText("Website = "+sitesList.getWebsite().get(i));

    //now we create a new row
    TableRow row = new TableRow(this);

    //we add the textviews to the row
    row.addView(name[i]);
    row.addView(website[i]);

    //and we add the row to the tablelayout
    layout.addView(row);
}

我真的希望这能帮助你继续下去。我一般建议看看 http://developer.android.com/guide/topics/resources/available-resources.html这是开始学习 Android 编程的最佳页面。
