Android(java)識別IOS裏plist文件

這個類用於在android裏面使用IOS中的plist文件，起初是想寫個小玩意自己看，找Json文件的時候只找到IOS中的plist文件，結果android裏面不能拿來直接用，網上找了下沒有現成可以讓我拿來直接用的，於是照着大佬們的思路寫了這麼一個工具類。目前可識別常見元素String，boolean，integer，list。

工具類

import org.xml.sax.SAXException;

使用

    try {
            SAXParserFactory factorys = SAXParserFactory.newInstance();
            SAXParser saxparser = factorys.newSAXParser();

			//這裏我把plist文件放到Asset下的
            InputStream is = mContext.getAssets().open("makeFriends.plist");
            PlistHandler plistHandler = new PlistHandler();
            saxparser.parse(is, plistHandler);
			//這裏我用了getArrayResult獲取，工具類裏面還有個getMapResult，視情況使用
            List<Object> array = plistHandler.getArrayResult();

			//接下來是我用fastjson將list轉成Json供自己後續使用的
            JSONArray jsonArray = (JSONArray) JSON.toJSON(array);

            for (int i = 0; i < jsonArray.size(); ++i) {
                JSONObject object = jsonArray.getJSONObject(i);
                list.add(object);
            }
        } catch (ParserConfigurationException e) {
            e.printStackTrace();
        } catch (SAXException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
