我正在开发一个 Android 应用程序来分析 UP Band 数据。使用 UP SDK for Android 中给出的示例，目前我可以将趋势数据作为 JSON 对象获取。问题是这个 JSON 对象格式不正确。事实上，当我尝试反序列化趋势数据时：

JsonElement je = new JsonParser().parse(o.toString());

我收到以下错误：

com.google.gson.JsonSyntaxException：com.google.gson.stream.MalformedJsonException：行中的预期值...

此外，检查 API 调用的结果，我得到：

前一个 JSON 对象的主要问题是键的格式不正确。实际上它们应该是“”之间的字符串。你能给我一些关于如何解决这个问题的指示吗？非常感谢你的帮助。[编辑]

这是我开始修改以从 Jawbone 获取数据的回调函数：

private Callback genericCallbackListener = new Callback<Object>() {
@Override
public void success(Object o, Response response) {
    Log.e(LOG_TAG,  "api call successful, json output: " + o.toString());
//I added the following 3 lines of code to parse the JSON result
    JsonElement je = new JsonParser().parse(o.toString());
    JsonObject root = je.getAsJsonObject();
    JsonElement je2 = root.get("Data");
    Toast.makeText(getApplicationContext(), je2.toString(), Toast.LENGTH_LONG).show();
}

@Override
public void failure(RetrofitError retrofitError) {
    Log.e(LOG_TAG,  "api call failed, error message: " + retrofitError.getMessage());
    Toast.makeText(getApplicationContext(), retrofitError.getMessage(), Toast.LENGTH_LONG).show();
}

};

好的，我相信我知道您的问题是什么。您正在使用改造Callback错误。

您不需要解析结果。Jawbone +改装将为您完成。

检查这个例子：

public interface BookService{
    @GET("/books")
    void getBooks(Callback<List<Book>> books);
}

// AND THEN

private Callback genericCallbackListener = new Callback<List<Book>>() {

    @Override
    public void success(List<Book> books, Response response) {
        [...] // use books
    }

    @Override
    public void failure(RetrofitError retrofitError) {

    }
}

taskService.getBooks(genericCallbackListener);

所以不要尝试手动解析响应。让Jawbone Android SDK为您完成。
