Question

我正在尝试通过改造来解析twitter / trends /将api解析到我的Android应用程序，但是，我已经能够通过改造解析下面的api并获得我所需的所有数据：

https://api.twitter.com/1.1/search/tweets.json，

对https://api.twitter.com/1.1/trends/place.json使用相同的方法，但我得到了这个例外

GSON投掷“预期BEGIN_OBJECT但是BEGIN_ARRAY

以下是我的代码。我相信我的错误来自下面的代码之一，有些人应该请帮助我。

TwitterApiService.java

public interface TwitterApiService {
    @GET(ApiConstants.TWITTER_TREND_SEARCH_CODE )
    void getTweetTagList(
            @Header("Authorization") String authorization,
            @Query("id") String id,
            Callback<TweetTagList> callback
    );

    @FormUrlEncoded
    @POST("/oauth2/token")
    void getToken(
            @Header("Authorization") String authorization,
            @Field("grant_type") String grantType,
            Callback<TwitterTokenType> response
    );


}

        this.mBus = bus;
    }

    @Subscribe
    public void onLoadTweets(final SearchTweetsTagEvent event) {
        mApi.getTweetTagList("Bearer " + event.twitterToken, event.id, new Callback<TweetTagList>() {

看起来您正在使用错误的模型对象进行JSON响应解析。您可以从twitter-kit-android中选择合适的一个。如果我理解正确Place.java正是您要找的。
