Android开发中处理Webservice的接口
SoapObject解析成List<String[]>二维数组
最近和Webservice对接接口,接到需求我乃一脸懵逼啊,废话不多说,看代码
首先是服务器接口给的url和方法名
private static final String TRANS_URL = "http://192.168.0.16:8005/WebService.asmx";
private static final String METHED = "DownLoadDataByFloor";
private static final String NAMESPACE = "http://tempuri.org/";//默认
NAMESPACE 可以在URL后面加上?wsdl既可以阅览,如下图

继续撸代码
private void getMesInfo(final String FloorName, String StepName, final String CurPage, final String PageSize) {
final Handler handler = new Handler() {
@Override
public void handleMessage(Message msg) {
super.handleMessage(msg);
if (msg.what == 100) {
if (dialogLoading != null) {
dialogLoading.closeDialog();
dialogLoading = null;
}
springView.onFinishFreshAndLoad();
springView.onFinishFreshAndLoad();
no_choose_tv.setVisibility(View.GONE);
SoapObject result = (SoapObject) msg.obj;
list.addAll(getSoapObj(result));
adapter.notifyDataSetChanged();
}else if (msg.what==101){
if (dialogLoading != null) {
dialogLoading.closeDialog();
dialogLoading = null;
}
springView.onFinishFreshAndLoad();
springView.onFinishFreshAndLoad();
no_choose_tv.setVisibility(View.GONE);
MyUtil.showAutoToast(context,"暂无更多数据");
if (list.size()==0){
no_choose_tv.setVisibility(View.VISIBLE);
no_choose_tv.setText("暂无更多数据");
}
}
}
};
Log.e("开始连接服务器", FloorName + StepName + "第" + CurPage + "页");
final SoapObject request = new SoapObject(NAMESPACE, METHED);
request.addProperty("FloorName", FloorName);
request.addProperty("StepName", StepName);
request.addProperty("CurPage", CurPage);
request.addProperty("PageSize", PageSize);
// request.addProperty("MaxPage", "3");
final SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.bodyOut = request;
envelope.dotNet = true;
envelope.setOutputSoapObject(request);
if (CurPage.equals("1")) {
dialogLoading = new DialogLoading(context, "加载中...");
list.clear();
adapter.notifyDataSetChanged();
}
new Thread(new Runnable() {
@Override
public void run() {
HttpTransportSE ht = new HttpTransportSE(TRANS_URL);
ht.debug = true;
try {
ht.call(soapAction, envelope);
SoapObject object = (SoapObject) envelope.bodyIn;
Message msg = new Message();
if (page>1&&((SoapObject)object.getProperty(0)).getPropertyCount()<1){
msg.what = 101;
page--;
}else{
msg.what = 100;
msg.obj = object;
}
handler.sendMessage(msg);
Log.e("getMesInfo", object.toString());
} catch (Exception e) {
runOnUiThread(new Runnable() {
@Override
public void run() {
MyUtil.showAutoToast(context,"连接超时");
no_choose_tv.setVisibility(View.VISIBLE);
no_choose_tv.setText("连接超时\n请确保您的网络为公司内网\n点击重新加载");
}
});
if (dialogLoading != null) {
dialogLoading.closeDialog();
dialogLoading = null;
}
Log.e("getMesInfo", e.getMessage().toString());
e.printStackTrace();
}
}
}).start();
}
这是笔者封装的网络请求,新开线程执行网络请求部分,然后在到handler处理更新listview和ui,其中
list.addAll(getSoapObj(result));```
中的`getSoapObj()`方法如下,花了一天时间才弄明白
private List<String[]> getSoapObj(SoapObject object){
String[] string = null;
List<String []> aaa=new ArrayList<>();
if (((SoapObject)object.getProperty(0)).getPropertyCount()>0){
for (int i=0;i<((SoapObject)object.getProperty(0)).getPropertyCount();i++){
string=new String[((SoapObject) ((SoapObject) object.getProperty(0)).getProperty(0)).getPropertyCount()];
for (int j=0;j< ((SoapObject) ((SoapObject) object.getProperty(0)).getProperty(i)).getPropertyCount();j++){
string[j]=((SoapObject) ((SoapObject) object.getProperty(0)).getProperty(i)).getProperty(j).toString();
}
if (string!=null){
aaa.add(i,string);
}
}
}else {
if (page==1){
no_choose_tv.setVisibility(View.VISIBLE);
no_choose_tv.setText("暂无更多数据");
}
}
return aaa;
}
####看着代码很冗长,其实SoapObject相当于数组,只是不能直接当成数组用,所以我们要把它的数据取出来自己弄到数组中去,在源码中我找到一个超级好用的方法
在SoapObject的源码中
public int getPropertyCount() {
return this.properties.size();
}
这个方法等于list.size().也就是放回SoapObject对象中当前层的长度
有了这个方法,就能对着获得的SoapObject对象toString()之后研究它的模型构造.比如
DownLoadDataByFloorResponse{DownLoadDataByFloorResult=anyType{ArrayOfString=anyType{string=4F DIP C线; string=DIP4F_C; string=TW.C.ITV050-G; string=4.002.1188; string=999; string=999; string=0; string=0.00%; }; ArrayOfString=anyType{string=4F DIP C线; string=DIP4F_C; string=TW.C.ITV050-J; string=4.002.1367; string=100; string=100; string=2; string=2.00%; }; ArrayOfString=anyType{string=4F DIP D线; string=DIP4F_D; string=TW.C.ITV041-H; string=4.002.1068; string=1772; string=1980; string=7; string=0.35%; }; }; MaxPage=2; }
接口人员说给我返回的List<String[]>,所以开始解析时我一直以为一定是这样,其实不然,已经发生了翻天覆地的变化.
然后就是一层一层的解析
`object.getProperty(0)`之后发现还是不能直接循环取数据,所以只能把`object.getProperty(0)`之后的对象继续转成SaopObject继续`getProperty()`,
由于WebService那边返回的确实是List<String[]>,所以Android这边在第二次`getProperty()`就能开始循环了,循环的对象就是List,第三次`getProperty()`后的循环就可以直接添加到String[]里面去了.大工搞成.
`listview.setAdapter(context,list);`
一切又回到了我喜欢样子.
