使用JSON在cus​​tomadapter中的服务器端值

Question

// CustomAdapter.java

{
  "slider": [
  {
    "name": "Demo Event",
    "images": "uploads\/event\/demo.png",
    "location": "Ernakulam"
  },
  {
    "name": "cfghedrgyedyg",
    "images": "uploads\/event\/Array466.jpg",
    "location": "dfgred"
  },
  {
    "name": "Demo",
    "images": "uploads\/event\/Array698.jpg",
    "location": "Thodupuzha"
  },
  {
    "name": "Event",
    "images": "uploads\/event\/Array745.jpg",
    "location": "Angamaly"
  },
  {
    "name": "ghtrfhy",
    "images": "uploads\/event\/Array350.jpg",
    "location": "Thodupuzha"
  }
 ]
}

我的json结果是，

int[] imageId = {R.drawable.slider1, R.drawable.slider2};

我的问题是，如何使用服务器中的值更改String[] caption = { "1", "2" };和 private async Task SaveSettings(Settings settings) { var folder = Windows.Storage.ApplicationData.Current.LocalFolder; var options = Windows.Storage.CreationCollisionOption.ReplaceExisting; var file = await folder.CreateFileAsync("Settings.XML", options); try { XmlSerializer SerializerObj = new XmlSerializer(typeof(Settings)); SerializerObj.Serialize(await file.OpenStreamForWriteAsync(), settings); } catch { // handle any kind of exceptions } } 中的值。即，使用JSON。

是否可以实现这一点。 我尝试了很多。但没有成功。

提前致谢。

像这样创建一个商业实体/类

public class ImageDetails()
{
public int ImageId;
public String Caption;
}

创建此类的列表作为对象并填充详细信息

    List<ImageDetails> imgDetails=new ArrayList<ImageDetails>();

ImageDetails img1=new ImageDetails();
img1.ImageId=1;
img1.Caption="Caption";

更改适配器的构造函数以接受此列表

public CustomAdapter(Context context,List<ImageDetails> imageDetails){
    this.context = context;
this.ImageDetails=imageDetails;
}

最后在getview

TextView textView = (TextView) viewItem.findViewById(R.id.textView1);
    textView.setText(ImageDetails.get(position).Caption);
