Question

可能重复：
Can we post image on twitter using twitter API in Android?

我在Android应用程序中工作，我想向Twitter发送一条消息和一张图片。我能够通过代码只发推特推文到推文：

String token = prefs.getString(OAuth.OAUTH_TOKEN, "");
String secret = prefs.getString(OAuth.OAUTH_TOKEN_SECRET, "");

AccessToken a = new AccessToken(token, secret);
Twitter twitter = new TwitterFactory().getInstance();
twitter.setOAuthConsumer(Constants.CONSUMER_KEY,
        Constants.CONSUMER_SECRET);
twitter.setOAuthAccessToken(a);
try {

**twitter.updateStatus("New tweet");**
        twitter.//Which property of twitter should I use to tweet an image and  //message
} catch (TwitterException e) {
    // TODO Auto-generated catch block
    Log.e("Errorssssssssssssss", e.toString());
}

我如何包含图片？

参考http://www.londatiga.net/it/how-to-post-twitter-status-from-android/，使用twitter4j库

public void uploadPic(File file, String message) throws Exception  {
    try{
    StatusUpdate status = new StatusUpdate(message);
    status.setMedia(file);
    mTwitter.updateStatus(status);}
    catch(TwitterException e){
        Log.d("TAG", "Pic Upload error" + e.getErrorMessage());
        throw e;
    }
}

其中mTwitter是Twitter类的实例

确保您使用的是最新版本的twitter4j-core jar文件。

你可以试试Twitter4j Library附带的例子。以下代码将帮助你

public final class TwitpicImageUpload {
    /**
     * Usage: java twitter4j.examples.media.TwitpicImageUpload [API key] [message]
     *
     * @param args message
     */
    public static void main(String[] args) {
        if (args.length < 2) {
            System.out.println("Usage: java twitter4j.examples.media.TwitpicImageUpload [API key] [image file path] [message]");
            System.exit(-1);
        }
        try {
            Configuration conf = new ConfigurationBuilder().setMediaProviderAPIKey(args[0]).build();
            ImageUpload upload = new ImageUploadFactory(conf).getInstance(MediaProvider.TWITPIC);
            String url;
            if (args.length >= 3) {
                url = upload.upload(new File(args[1]), args[2]);
            } else {
                url = upload.upload(new File(args[1]));
            }
            System.out.println("Successfully uploaded image to Twitpic at " + url);
            System.exit(0);
        } catch (TwitterException te) {
            te.printStackTrace();
            System.out.println("Failed to upload the image: " + te.getMessage());
            System.exit(-1);
        }
    }
}
