本文介绍了在 Android 中 - 如何在不打开推文对话框(消息对话框)的情况下直接将推文发布到 android 中经过身份验证的用户的后续用户的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我想向 Authenticate 用户的以下用户发布推文.使用 Twitter-4j 库 进行身份验证.我获得了以下用户的列表(名称和 ID),但无法发布推文没有打开对话框.我正在使用此身份验证链接

I want to post tweet to following users of a Authenticate user.For authenticate using Twitter-4j library .I have get list(Name & id) of following users but not able to post tweet without open dialog.I am usingthis link for authenticate

问题-如何在不打开推文对话框(消息对话框)的情况下,在android中直接向认证用户的关注用户发布推文

1.在 twitterButton 上点击一个使用 webview 打开的新活动

    twitterButton=(Button) findViewById(R.id.twitter);
    twitterButton.setOnClickListener(new OnClickListener() {

    @Override
    public void onClick(View v) {
        // TODO Auto-generated method stub


        mTwitter = new TwitterFactory().getInstance();
        mRequestToken = null;
        mTwitter.setOAuthConsumer(TwitterConstants.CONSUMER_KEY,
                TwitterConstants.CONSUMER_SECRET);
        String callbackURL = getResources().getString(
                R.string.twitter_callback);
        try {
            mRequestToken = mTwitter.getOAuthRequestToken(callbackURL);
            System.out.println("URL"
                    + mRequestToken.getAuthenticationURL());
        } catch (TwitterException e) {
            e.printStackTrace();
        }
        Intent i = new Intent(MMSExampleActivity.this,
                TwitterScreen.class);
        i.putExtra("URL", mRequestToken.getAuthenticationURL());
        System.out.println("Url ==== "
                + mRequestToken.getAuthenticationURL());
        startActivityForResult(i, TWITTER_AUTH);

    }
       });

2.在 onActivityResult(int requestCode, int resultCode, Intent data) 方法中

                 if (resultCode == Activity.RESULT_OK) {
                String oauthVerifier = (String) data.getExtras().get(
                        "oauth_verifier");
                AccessToken at = null;
                try {
                    // Pair up our request with the response
                    at = mTwitter.getOAuthAccessToken(mRequestToken,
                            oauthVerifier);

                    accessToken = at.getToken();
                    System.out.println("access token" + accessToken);
                    accessTokenSecret = at.getTokenSecret();

                    getFollowers();

                    Intent twitterFriendIntent=new Intent(MMSExampleActivity.this,TwitterFriends.class);
                    twitterFriendIntent.putExtra("twitterfriends", twitterFriends);
                    startActivity(twitterFriendIntent);
                } catch (TwitterException e) {
                    System.out.println("e........");
                    e.printStackTrace();

                }
            }

3.获取关注用户列表

     public void getFollowers()
                    {
        ConfigurationBuilder builder = new ConfigurationBuilder();
        builder.setOAuthConsumerKey(TwitterConstants.CONSUMER_KEY);
        builder.setOAuthConsumerSecret(TwitterConstants.CONSUMER_SECRET);
        builder.setOAuthAccessToken(accessToken);
        builder.setOAuthAccessTokenSecret(accessTokenSecret);
        Configuration conf = builder.build();
         twitter = new TwitterFactory(conf).getInstance();


        try {

            long lCursor = -1;
            IDs friendsIDs = twitter.getFriendsIDs(twitter.getId(), lCursor);
            IDs followersIds=twitter.getFollowersIDs(twitter.getId(), lCursor);
            System.out.println(twitter.showUser(twitter.getId()).getName());
            System.out.println("==========================");
            do
            {
              for (long i : friendsIDs.getIDs())
               {


                  FriendList friendListObj=new FriendList();
                  friendListObj.setTwitterId(i);
                  friendListObj.setTwitterUsername(twitter.showUser(i).getName());
                  friendListObj.setTwitterUrl(twitter.showUser(i).getScreenName());
                  twitterFriends.add(friendListObj);

                   System.out.println("follower ID #" + i);
                   System.out.println(twitter.showUser(i).getName());
                   System.out.println(twitter.showUser(i).getProfileImageURL());
                   System.out.println(twitter.showUser(i).getURL());

               }
            }while(friendsIDs.hasNext());

        } catch (IllegalStateException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (TwitterException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

    }

4.发布推文的代码

      public void updateStatus( String messageToPost) {

    ConfigurationBuilder builder = new ConfigurationBuilder();
    builder.setOAuthConsumerKey(TwitterConstants.CONSUMER_KEY);
    builder.setOAuthConsumerSecret(TwitterConstants.CONSUMER_SECRET);
    builder.setOAuthAccessToken(accessToken);
    builder.setOAuthAccessTokenSecret(accessTokenSecret);
    Configuration conf = builder.build();
    Twitter twitter = new TwitterFactory(conf).getInstance();

    System.out.println("in update status");
    try {
        // twitter.updateStatus("Hello World!");
        StatusUpdate status = new StatusUpdate(messageToPost);
        System.out.println("Length of Message is = = = "
                + messageToPost.trim().length());
        System.out.println("App" + file);
        status.setMedia(file);
        System.out.println("App" + file.exists());
        twitter.updateStatus(status);
        System.out.println("App" + file);
    } catch (TwitterException e) {
        System.err.println("Error occurred while updating the status!");
        e.printStackTrace();

    }

}
