Android学习之——（三）项目中的WebService返回数据处理学习

        接上一篇http://blog.csdn.net/fu222cs98/article/details/21554339

在项目中通过WebService调用服务端方法，服务端采用C#编写，当初公司项目应该是没有考虑到android方面（那时候android还没火起来吧），所以在设计方面可能不是那么规范吧（个人理解）。因为服务端返回的数据要么是基础类型数据，要么就是直接返回一个类，返回一个Datatable，返回一个Dataset，一个类里面还可能包含其他的类。这就直接导致了现在android的这块解析返回数据方面产生巨大的麻烦。

        幸好，这个问题已经解决了。下面就将给出其中的一些解析方式。

        关于在android中调用WebService的方法可以具体参考这篇文章：http://www.open-open.com/bbs/view/1320111271749?sort=newest

        其中下面代码当中有用到FanShe这个类在我前面的文章当中有提到过http://blog.csdn.net/fu222cs98/article/details/21552199 里面的 c. 通过反射将obj类的属性列表一个个赋值以及 f. 通过反射对类进行解析并赋值

/**
 * 数据解析接口
 */
public interface ParseData {
    /**
     * @param result
     *            Soap数据对象
     * @param cla
     *            Class类
     * @param entityname
     *            包名
     * @return
     */
    public abstract Object doing(SoapObject result,
            @SuppressWarnings("rawtypes") Class cla, String entityname)
            throws NoSuchFieldException, IllegalAccessException,
            InstantiationException, ClassNotFoundException;
}

二、返回数据为单个类的情况

/**
 * 数据为单个类
 * @author Administrator
 */
public class OneClass implements ParseData {
    @Override
    public Object doing(SoapObject result,
            @SuppressWarnings("rawtypes") Class cla, String entityname)
            throws NoSuchFieldException, IllegalAccessException,
            InstantiationException, ClassNotFoundException {
        // TODO Auto-generated method stub
        FanShe fs = new FanShe();
        Object obj = fs.useFanSheToData(result, cla.newInstance(), entityname);
        return obj;
    }
}

三、数据为多个String的情况

/**
 * 数据为多个String
 * @author Administrator
 */
public class ManyString implements ParseData {
    @Override
    public Object doing(SoapObject result,
            @SuppressWarnings("rawtypes") Class cla, String entityname)
            throws NoSuchFieldException, IllegalAccessException,
            InstantiationException, ClassNotFoundException {
        // TODO Auto-generated method stub
        String[] zsts = new String[result.getPropertyCount()];
        for (int i = 0; i < result.getPropertyCount(); i++) {
            zsts[i] = result.getProperty(i).toString();
        }
        return zsts;
    }
}

四、数据为List<Object>的情况下：

/**
 * 数据为List<Object>
 * @author Administrator syc
 */
public class GetListClass implements ParseData {
    @Override
    public Object doing(SoapObject result,
            @SuppressWarnings("rawtypes") Class cla, String entityname)
            throws NoSuchFieldException, IllegalAccessException,
            InstantiationException, ClassNotFoundException {
        // TODO Auto-generated method stub
        boolean flag = false;
        FanShe fs = new FanShe();
        List<Object> clalist = new ArrayList<Object>();
        // 一个个类的属性赋值,判断是否为空
        for (int j = 0; j < result.getPropertyCount(); j++) {
            if (((SoapObject) result.getProperty(j)).getProperty(0).toString()
                    .indexOf("anyType") >= 0) {
                flag = true;
                break;
            }
        }
        //不为空反射
        if (flag) {
            SoapObject table = (SoapObject) result.getProperty(0);
            for (int j = 0; j < table.getPropertyCount(); j++) {
                if (table.getProperty(j).toString().indexOf("anyType") >= 0) {
                    // System.out.println(table.getProperty(j).toString());
                    Object obj = fs.useFanSheToData(
                            (SoapObject) table.getProperty(j),
                            cla.newInstance(), entityname);
                    clalist.add(obj);
                }
            }
        } else {
            for (int i = 0; i < result.getPropertyCount(); i++) {
                SoapObject table = (SoapObject) result.getProperty(i);
                Object obj = fs.useFanSheToData(table, cla.newInstance(),
                        entityname);
                clalist.add(obj);
            }
        }
        return clalist;
    }
}

五、数据为DataTable的情况下解析

/**
 * 数据为DateTable类型解析
 * @author Administrator syc
 */
public class DataTable implements ParseData {
    @Override
    public Object doing(SoapObject result,
            @SuppressWarnings("rawtypes") Class cla, String entityname)
            throws NoSuchFieldException, IllegalAccessException,
            InstantiationException, ClassNotFoundException {
        // TODO Auto-generated method stub
        FanShe fs = new FanShe();
        List<Object> list = new ArrayList<Object>();
        if (result.toString().indexOf("diffgram") >= 0) {
            //System.out.println(result.getProperty("diffgram").toString());
            if (result.getProperty("diffgram").toString().equals("anyType{}")) {
                return null;
            }
            SoapObject diffgram = (SoapObject) result.getProperty("diffgram");
 
            SoapObject documentelement = (SoapObject) diffgram.getProperty(0);
            for (int i = 0; i < documentelement.getPropertyCount(); i++) {
                // System.out.println(i);
                // System.out.println(documentelement.getPropertyCount());
                SoapObject bedtable = (SoapObject) documentelement
                        .getProperty(i);
                Object obj = fs.useFanSheToData(bedtable, cla.newInstance(),
                        entityname);
                list.add(obj);
            }
        }
        return list;
    }
}

六、数据为DataSet的数据解析

/**
 * 数据为DateSet类型解析
 * @author Administrator
 */
public class DataSet implements ParseData {
    @Override
    public Object doing(SoapObject result,
            @SuppressWarnings("rawtypes") Class cla, String entityname)
            throws NoSuchFieldException, IllegalAccessException,
            InstantiationException, ClassNotFoundException {
        // TODO Auto-generated method stub
        Object obj = null;
        if (result.toString().indexOf("diffgram") >= 0) {
            SoapObject diffgram = (SoapObject) result.getProperty("diffgram");
            obj = obtainshuju(diffgram, cla, entityname);
        }
        return obj;
    }
    /**
     * 有diffgram把传回来的list数据解析在反射
     * @param diffgram
     * @param cla
     */
    public Object obtainshuju(SoapObject diffgram,
            @SuppressWarnings("rawtypes") Class cla, String entityname)
            throws NoSuchFieldException, IllegalAccessException,
            InstantiationException, ClassNotFoundException {
        FanShe fs = new FanShe();
        List<Object> clalist = new ArrayList<Object>();
        SoapObject NewDataSet = (SoapObject) diffgram.getProperty("NewDataSet");
        if (NewDataSet.getPropertyCount() == 1
                && ((SoapObject) NewDataSet.getProperty(0)).getPropertyCount() == 1) {
            return ((SoapObject) NewDataSet.getProperty(0)).getProperty(0)
                    .toString();
        }
        // 取得一个个类的属性赋值
        for (int i = 0; i < NewDataSet.getPropertyCount(); i++) {
            SoapObject table = (SoapObject) NewDataSet.getProperty(i);
            System.out.println(table.toString());
            Object obj = fs.useFanSheToData(table, cla.newInstance(),
                    entityname);
            clalist.add(obj);
        }
        return clalist;
    }
}

七、类中有类的数据解析

/**
 * 类中有类
 * @author Administrator syc
 */
public class Classinclass implements ParseData {
    @Override
    public Object doing(SoapObject result,
            @SuppressWarnings("rawtypes") Class cla, String entityname)
            throws NoSuchFieldException, IllegalAccessException,
            InstantiationException, ClassNotFoundException {
        FanShe fs = new FanShe();
        List<Object> list = new ArrayList<Object>();
        for (int i = 0; i < result.getPropertyCount(); i++) {
            SoapObject result1 = (SoapObject) result.getProperty(i);
            // System.out.println(result.toString());
            Object obj = fs.useFanSheToData(result1, cla.newInstance(),
                    entityname);
            list.add(obj);
        }
        return list;
    }
}
