我有一个异步任务类，它获取Web方法的名称并运行它，我必须等待该Web方法的结果，所以我使用task.execute .get（）方法冻结了我的UI。问题是我想在任务执行时显示一个加载对话框，但是当我试图为10个Web方法调用此方法10次时，UI冻结并且在执行10个Web方法后，加载对话框出现1秒。
我可以做什么来显示加载而无需将所有代码移入doInBackground？我想要一个获取Web方法信息并返回结果的类。这是我的类代码：显示加载的UI冻结异步任务像这样
public class AsyncCallWs extends AsyncTask<String, Void, String> {
private ProgressDialog dialog;
public String methodName="";
private WebService ws;
private ArrayList<ServiceParam> paramsList;
private boolean hasParams;
public AsyncCallWs(Activity activity,String methodName) {
xLog.position();
try {
this.dialog = new ProgressDialog(activity);
this.methodName = methodName;
hasParams = false;
} catch (Exception e) {
xLog.error(e.getMessage());
}
}
public AsyncCallWs(Activity activity,String methodName,ArrayList<ServiceParam> params) {
xLog.position();
try {
this.dialog = new ProgressDialog(activity);
this.methodName = methodName;
this.paramsList = params;
hasParams = true;
} catch (Exception e) {
xLog.error(e.getMessage());
}
}
@Override
protected void onPreExecute() {
this.dialog.setMessage(PersianReshape.reshape("Loading..."));
this.dialog.show();
}
@Override
protected String doInBackground(String... params) {
xLog.position();
String result = "No async task result!";
try {
ws = new WebService(PublicVariable.NAMESPACE, PublicVariable.URL);
if (!hasParams){
result = ws.CallMethod(methodName);
}
else{
xLog.info("THIS METHOD IS: "+ methodName);
result = ws.CallMethod(methodName,paramsList);
xLog.info("THIS RESULT IS: "+ result);
}
} catch (Exception e) {
xLog.error(e.getMessage());
}
return result;
}
@Override
protected void onPostExecute(String result) {
xLog.position();
if (this.dialog.isShowing()) {
this.dialog.dismiss();
}
xLog.info("Output of current AsyncTask is:"+ result);
}
}
这是我打电话使用这个类Web方法的方式：

serviceParams.add(new ServiceParam("pGuid", PublicVariable.pGuid, String.class));

try {
t = new AsyncCallWs(activity,"GetPersonInfo",serviceParams);
result = t.execute().get();
xLog.info("Sync Person=>"+ result);
