我正在使用GSON Library解析本地JSON.这是我的json结构

{
  "employees":[
  {
   "id":100,
   "name":"Ranjith"
  },
  {
   "id":101,
   "name":"Satheesh"
  }]
}

我必须在列表视图中显示.这是我的代码

public void loadfromfile()
{
    try {
        AssetManager am = getAssets();
        InputStream is = am.open("sample.json");
        BufferedReader br=new BufferedReader(new InputStreamReader(is));
        Gson gson=new Gson();
        JsonReader reader=new JsonReader(br);
        reader.beginObject();
        while (reader.hasNext()) {

            String name = reader.nextName();

            if (name.equals("success")) {
                success =reader.nextBoolean();
            }

            else if(name.equals("employees")){
                reader.beginArray();
                while (reader.hasNext()) {

                    Employee employee= gson.fromJson(String.valueOf(reader), Employee.class);

                    emplist.add(employee);
                }
                reader.endArray();
            }
        }

     reader.endObject();
     reader.close();
        dataAdapter.notifyDataSetChanged();
    }catch (IOException ex){

        ex.printStackTrace();
    }

当我运行此IllegalStateException时：预期为BEGIN_OBJECT但在第1行第1列处为STRING.我正在使用一个单独的类来设置和获取json中的字段.

解决方法:

确保您导入

 import com.google.gson.stream.JsonReader

不要将其转换为String,将阅读器直接传递给gson.

Employee employee= gson.fromJson(reader, Employee.class);
