gson与混合阅读

Question

我正在尝试使用gson读取json,但我无法获得一个"简单"的gson示例.

来自:https://sites.google.com/site/gson/streaming

    public List<Message> readJsonStream(InputStream in) throws IOException {
      JsonReader reader = new JsonReader(new InputStreamReader(in, "UTF-8"));
      List<Message> messages = new ArrayList<Message>();
      reader.beginArray();
      while (reader.hasNext()) {
          Message message = gson.fromJson(reader, Message.class);
          messages.add(message);
      }
      reader.endArray();
      reader.close();
      return messages;
   }

这是问题,如果我尝试:

JsonReader reader;
Gson gson = new Gson();
gson.fromJson(reader,Program.class);

它甚至没有建立.

The method fromJson(String, Class<T>) in the type Gson is not applicable for the arguments (JsonReader, Class<Program>)

根据eclipse似乎有一种方法: fromJson(JsonReader arg0,Type arg1)

更换

import android.util.JsonReader;   

同

import com.google.gson.stream.JsonReader 

做到了!=)
