java - 如何使用自己的应用程序在 Twitter 上发布推文

Question

我想在 Twitter 上发布我的应用程序的推文。这条推文将显示在我的应用程序和 Twitter 中。

我拥有该用户的所有详细信息，但我不想登录 Twitter。这是我从网络服务获取的格式:

<string xmlns="http://tempuri.org/">
    {"Id":"cc02cf6c-c143-4921-b5d6-6afec1243c10","TwitterUserId":"123456",
     "TwitterScreenName":"abc", "OAuthToken":"xxxxxxxxxxxxxxxxxxxx",
     "OAuthSecret":"xxxxxxxxxxxx", "UserId":"zzzzzzzzzz", "FollowersCount":1, "IsActive":true,
     "FollowingCount":13, "ProfileUrl":"", "ProfileImageUrl":"http://abs.xxxxxxxxxxxxx.png",
     "TwitterName":null}
</string>

下面是我在 Twitter 上发布推文的代码，但这里他们使用 Twitter 登录。 我不想登录。

请指导我，或者如果可能的话，请提供一些示例代码。

我正在使用 twitter4j 库。

public class MainActivity extends Activity implements OnClickListener { 

    // Constants

 ConfigurationBuilder configurationBuilder = new ConfigurationBuilder();
    configurationBuilder.setOAuthConsumerKey(context.getResources().getString(R.string.twitter_consumer_key));
    configurationBuilder.setOAuthConsumerSecret(context.getResources().getString(R.string.twitter_consumer_secret));
    configurationBuilder.setOAuthAccessToken("HERE ENTER UR ACCESS TOKEN RECEIVED IN YOUR WEB SERVICE"));
    configurationBuilder.setOAuthAccessTokenSecret("HERE ENTER UR ACCESS TOKEN SECRET RECEIVED IN YOUR WEB SERVICE"));
    Configuration configuration = configurationBuilder.build();
    final Twitter twitter = new TwitterFactory(configuration).getInstance();

    new Thread(new Runnable() {

            private double x;

            @Override
            public void run() {
                    boolean success = true;
                    try {
                            x = Math.random();
                            twitter.updateStatus(message +" "+x);
                    } catch (TwitterException e) {

                            success = false;
                    }

                    final boolean finalSuccess = success;

                    callingActivity.runOnUiThread(new Runnable() {

                            public void run() {
                                    postResponse.onFinsihed(finalSuccess);
                            }
                    });

            }
    }).start(); 

如果您有有效的访问 token 和访问 token key ，则上述方法将允许您发布推文。干杯:)
