如何将数组列表更改为字符串数组以使用通用图像加载器? [英] How to change array list to string array for using Universal Image Loader?

问题描述

我是安卓新手.我只是尝试学习如何使用 Universal Image Loader.我发现 Universal Image Loader 中图像的 url 是静态设置的或在 String[] IMAGES 中预设的.但我想从 URL 更改这些图像.所以我完成了解析 XML 并尝试从 XML Web 服务 获取这些数据.

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.

但是，我不知道如何将数组列表更改为字符串数组.有人可以教我吗?

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

xml web service 代码如下:

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;
    }
}
