如何改变数组列表以字符串数组使用通用图像装载机？ [英] How to change array list to string array for using Universal Image Loader?

问题描述

我的android的新手。我只是尝试学习如何使用通用图像装载机。
我发现网​​址图像的通用图像装载机静态设置或preSET在的String []图片。不过，我想对那些图像从网​​址更改。因此，我与解析 XML完成，并尝试从 XML Web服务。

这些数据

不过，我不知道如何改变数组列表字符串数组。有人可以教我吗？

的 XML Web服务 code如下：

 类showCategoryTask扩展的AsyncTask＆LT;太虚，太虚，太虚＆GT; {
    @覆盖
    保护无效doInBackground（虚空...... PARAMS）{
        尝试{
            网址URL =新的URL（http://garyhui86.er-webs.com/monstersxml.php）;
            HttpURLConnection的urlConn =
                                 （HttpURLConnection类）url.openConnection（）;
            如果（urlConn.getResponse code（）== HttpURLConnection.HTTP_OK）{
                的DocumentBuilder建设者=的DocumentBuilderFactory
                        。.newInstance（）newDocumentBuilder（）;
                文献文件= builder.parse（urlConn.getInputStream（））;
                节点列表节点列表= document.getElementsByTagName（信息）;
                的for（int i = 0; I＆LT; nodeList.getLength（）;我++）{
                    的NamedNodeMap属性= nodeList.item（ⅰ）.getAttributes（）;
                    字符串monstersname = attributes.getNamedItem（monsters_name）getNodeValue（）。
                    字符串monstersimage = attributes.getNamedItem（monsters_image）getNodeValue（）。
                    Log.i（TTT，monstersname）;
                    Monsters_image.add（monstersimage）;
                }
            }
            urlConn.disconnect（）;
        }赶上（例外五）{
            e.printStackTrace（）;
        }
        返回null;
    }
}
 

解决方案

将您的字符串的ArrayList 为字符串阵列像

 的String []海峡= list.toArray（新的String [则为list.size（）]）;
 

I am a Novice of android. I just try to learn how to use Universal Image Loader. I find that the url of the images in Universal Image Loader are set statically or preset in String[] IMAGES. But I would like to change those image from URL. So I am done with parsing the XML and try to get those data from XML Web service.

However, I don't know how to change array list to string array. Can someone teach me?

The xml web service code as follow:

class showCategoryTask extends AsyncTask<Void, Void, Void> {
    @Override
    protected Void doInBackground(Void... params) {
        try {
            URL url = new URL("http://garyhui86.er-webs.com/monstersxml.php");
            HttpURLConnection urlConn = 
                                 (HttpURLConnection)url.openConnection();
            if (urlConn.getResponseCode() == HttpURLConnection.HTTP_OK) {
                DocumentBuilder builder = DocumentBuilderFactory
                        .newInstance().newDocumentBuilder();
                Document document = builder.parse(urlConn.getInputStream());
                NodeList nodeList = document.getElementsByTagName("Info");
                for (int i = 0; i < nodeList.getLength(); i++) {
                    NamedNodeMap attributes=nodeList.item(i).getAttributes();
                    String monstersname=attributes.getNamedItem("monsters_name").getNodeValue();
                    String monstersimage=attributes.getNamedItem("monsters_image").getNodeValue();
                    Log.i("ttt", monstersname);
                    Monsters_image.add(monstersimage);
                }
            }
            urlConn.disconnect();
        } catch (Exception e) {
            e.printStackTrace();
        }
        return null;
    }
}

解决方案

Convert your String ArrayList to String Array like

 String[] str=list.toArray(new String[list.size()]);
