Android和Azure的移动服务：使用invokeAPI返回记录集 [英] Android and Azure Mobile Services: Using invokeAPI to return recordset

问题描述

我想很简单的东西。我有一个名为missingvehiclesfrominventoryjob的自定义API，它只是返回从标准的SQL查询创下了一个纪录。

I am trying something very simple. I have a custom API called "missingvehiclesfrominventoryjob" and it simply returns a record set from an standard SQL Query.

我可以在我的WinForms和Windows Phone应用程序做到这一点很容易，但我无法弄清楚如何做到这一点的Andr​​oid应用程序。

I can do this in my WinForms and Windows Phone app easily but I cannot figure out how to do this on the Android App.

下面是我的code：（不Android Studio中编译）：

Here is my code: (which DOES NOT COMPILE in Android Studio):

msClient.invokeApi("missingvehiclesfrominventoryjob", kd, new     
ApiOperationCallback<List<InventoryProspects>>(){
            @Override
            public void onCompleted(List<InventoryProspects> missingVehicles, Exception e,  
                   ServiceFilterResponse serviceFilterResponse){
                     for (InventoryProspects item : missingVehicles){
                        mAdapter.add(item);
                     }
               }
        });

问题是在列表中的回调的参数即可。我不知道如何表明invoiceAPI通话将被从数据库返回多个行，我不能在任何地方文档找到解释如何。我也不能在互联网上找到一个示例的任何地方。

The problem is the List in the parameters of the Callback. I am not sure how to indicate that the invoiceAPI call will return multiple rows from the database and I cannot find anywhere in the docs to explain how. Nor can I find an example ANYWHERE on the internet.

我相信我不是唯一在试图做到这一点。

I am sure I am not the only on trying to do this.

在此先感谢

推荐答案

我做了什么来解决这个问题，是调用invokeApi一个返回JsonElement不同的过载，然后deserialise到我的对象，像这样：

What i did to overcome this problem, is to call a different overload of invokeApi that returns a JsonElement, and then deserialise it into my objects like so:

mClient.invokeApi("MyCustomApi",null, "GET", null, new ApiJsonOperationCallback() {
        @Override
        public void onCompleted(JsonElement jsonElement, Exception e, ServiceFilterResponse serviceFilterResponse) {
            GsonBuilder gsonb = new GsonBuilder();
            Gson gson = gsonb.create();

            JsonArray array = jsonElement.getAsJsonArray();
            List<MyObject> myObjects = new ArrayList<MyObject>()>
            for(int i = 0; i < array.size(); i++)
            {
                myObjects.add(gson.fromJson(array.get(i).getAsJsonObject().toString(), MyObject.class));
            }
        }
    });
