Twitter更新状态 [英] Twitter update status

问题描述

我正在通过twitter4j将Twitter集成到Android.我可以成功阅读我发布的推文.

I am integrating Twitter to Android through twitter4j. I can successfully read tweets posted by me.

现在我正尝试从中发布推文，但我不能.我收到如下奇怪警告:

Now I am trying to posting tweet from it, but I can't. I am getting strange warning as below:

尽管我已将Twitter中的应用程序设置为可读写，但它说我不能按只读应用程序发布.

Though I have set my application in Twitter as read and write, it says I can't post by read only app.

推荐答案

在Twitter上发布推文与获取时间表是不同的.

Posting a tweet on twitter is different than getting the timeline.

将Twitter4J考虑在内，情况可能如下:

Taking Twitter4J into account the scenarios may be following:

它要求您拥有已授权的Twitter类的实例.

It requires you to have an instance of Twitter class which is authorised.

您需要执行以下操作以获取时间表:

You do following in order to get the timeline:

Twitter twitter = new TwitterFactory().getInstance();
twitter.setOAuthConsumer(consumerKey, consumerSecret);
RequestToken requestToken = twitter.getOAuthRequestToken(CALLBACKURL); 
...
...

OAuth验证成功后，您将获得oauth_verifier变量，然后使用以下几行创建一个AccessToken:

After successful OAuth verification, you get the oauth_verifier variable, and then create an AccessToken with the following lines:

AccessToken accessToken = twitter.getOAuthAccessToken(requestToken,oauth_verifier);
String token = accessToken.getToken(), 
      secret = accessToken.getTokenSecret();

将上面的token和secret保存在某个地方，以后将用于生成AccessToken.

Save the above token and secret somewhere, it will be used in generating the AccessToken later.

现在，更新状态的代码:

Now, the code to update status:

AccessToken accessToken = new AccessToken(token,secret);
Twitter twitter = new TwitterFactory().getOAuthAuthorizedInstance(consumerKey,consumerSecret,accessToken);
Status status = twitter.updateStatus("My First Status Update");
statusId = (int)status.getId();

这会将消息My First Status Update更新到您的时间轴，并在statusId变量中获取此状态的ID.

This will update the message My First Status Update to your timeline and will get the ID of this status in the statusId variable.

我敢肯定，在对其稍加修改并在其中使用了上面的代码之后，您也可以将其转换为推文发布代码！

I am sure that after a slight modification into that and the use of above code in it, you can transform it into a tweet posting code too!
