我想在Twitter上发布我的应用程序的推文。这条推文将在我的应用程序以及推特中显示。
我有用户的所有细节，我不想在Twitter上登录。以下是我从Web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，但是他们在这里使用twitter登录。 我不想登录。
请指导我，如果可能的话，请提供一些示例代码。
我正在使用twitter4j库。

如果您拥有有效的访问令牌和访问令牌密钥，则上述方法将允许您发布推文。 干杯：）

以下是在Twitter上发布消息的代码
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(LoginActivity.getAccessToken((context)));
configurationBuilder.setOAuthAccessTokenSecret(LoginActivity.getAccessTokenSecret(context));
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) {
e.printStackTrace();
success = false;
}
final boolean finalSuccess = success;
callingActivity.runOnUiThread(new Runnable() {
@Override
public void run() {
postResponse.onFinsihed(finalSuccess);
}
});
}
}).start();
