如何从Twitter获取家庭时间轴数据

Question

我开发了一个应用程序。在我的应用程序中，我想获取Twitter主页时间轴数据并显示listview。并且我使用了twitter4j库。我进行了很多搜索并阅读了twitter文档。在此文档中，使用了波纹管获取用户时间轴数据webservice：“ https://api.twitter.com/1/statuses/user_timeline.json?include_entities=true&include_rts=true&screen_name=twitterapi&count=2 ”。它工作正常，将显示数据。但我的要求是获取家庭时间轴数据在该文档中，他们提供了以下Web服务： https : //api.twitter.com/1.1/statuses/home_timeline.json 。这不起作用，并且不会显示家庭时间轴数据。请任何一个建议我，如何做。提前致谢

Answer 1

使用此代码。 这是我的一个应用程序的生产代码。 我从strings.xml文件中获取了两个Strings TWITTER_CONSUMER_KEY和TWITTER_CONSUMER_SECRET值。 从我的SharedPreferences文件中提取了Strings twit_access_token和twit_access_token_secret的值。 用您自己的存储方法替换这些位。

try {
    ConfigurationBuilder builder = new ConfigurationBuilder();

    // GET THE CONSUMER KEY AND SECRET KEY FROM THE STRINGS XML
    String TWITTER_CONSUMER_KEY = getActivity().getString(R.string.TWITTER_CONSUMER_KEY);
    String TWITTER_CONSUMER_SECRET = getActivity().getString(R.string.TWITTER_CONSUMER_SECRET);

    // TWITTER ACCESS TOKEN
    String twit_access_token = twitPrefs.getString(PREF_KEY_OAUTH_TOKEN, null);

    // TWITTER ACCESS TOKEN SECRET
    String twit_access_token_secret = twitPrefs.getString(PREF_KEY_OAUTH_SECRET, null);

    builder.setOAuthConsumerKey(TWITTER_CONSUMER_KEY);
    builder.setOAuthConsumerSecret(TWITTER_CONSUMER_SECRET);
    builder.setOAuthAccessToken(twit_access_token);
    builder.setOAuthAccessTokenSecret(twit_access_token_secret);
    builder.setJSONStoreEnabled(true);
    builder.setIncludeEntitiesEnabled(true);
    builder.setIncludeMyRetweetEnabled(true);
    builder.setIncludeRTsEnabled(true);

    AccessToken accessToken = new AccessToken(twit_access_token, twit_access_token_secret);
    Twitter twitter = new TwitterFactory(builder.build()).getInstance(accessToken);

    Paging paging = new Paging(200); // MAX 200 IN ONE CALL. SET YOUR OWN NUMBER <= 200
    statuses = twitter.getHomeTimeline(paging);

    try {
        String strInitialDataSet = DataObjectFactory.getRawJSON(statuses);
        JSONArray JATweets = new JSONArray(strInitialDataSet);

        for (int i = 0; i < JATweets.length(); i++) {
                JSONObject JOTweets = JATweets.getJSONObject(i);
                Log.e("TWEETS", JOTweets.toString());
        }

    } catch (Exception e) {
        // TODO: handle exception
    }
} catch (Exception e) {
    // TODO: handle exception
}

注意1： statuses是List<Status> statuses = new ArrayList<Status>();的实例List<Status> statuses = new ArrayList<Status>(); 我已经声明并实例化为全局实例。

注2：该属性是必需的builder.setJSONStoreEnabled(true); 如果您希望结果为JSON格式。 如果您需要不带JSON ，请告诉我。

最后更新：

在测试了OP的全部代码并调试了测试应用程序中的所有内容之后，罪魁祸首变成了一行（实际上是2行）：

Paging paging = new Paging(200); // MAX 200 IN ONE CALL. SET YOUR OWN NUMBER <= 200
statuses = twitter.getHomeTimeline(paging);

事实证明，由于某种原因，Twitter API不喜欢Paging paging = new Paging(200); 。 将其更改为Paging paging = new Paging(10); 奇怪的是，给了我20条推文。 完全删除Paging....行，给了我19 。 结果很奇怪。 但是我目前最好的猜测是，该应用程序可能是Twitter开发人员网络上的新程序（它在身份验证期间仍显示该应用程序无法访问Direct Messages ）。

将该部分更改为：

// Paging paging = new Paging(10);
statuses = twitter.getHomeTimeline();
