本文介绍了Twitter的集成API不工作的处理方法，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

首先，我已经下载 twitter4j-3.0.3 键，把它的的.jar 文件到库文件夹，我创建 https://dev.twitter.com/ ，并得到所有的凭据需要并给回调URL为 https://google.co.in

现在我的code是如下：

 进口twitter4j.Twitter;
进口twitter4j.TwitterException;
进口twitter4j.TwitterFactory;
进口twitter4j.User;
进口twitter4j.auth.AccessToken;
进口twitter4j.auth.RequestToken;

进口twitter4j.conf.ConfigurationBuilder;
进口android.app.Activity;
进口android.content.Intent;
进口android.net.Uri;
进口android.os.Bundle;
进口android.util.Log;
进口android.view.View;
进口android.widget.Button;

        的setContentView（R.layout.activity_twitter）;        loginButton =（按钮）findViewById（R.id.twitter_log_in）;
        logoutButton =（按钮）findViewById（R.id.twitter_log_out）;
        sendStatus =（按钮）findViewById（R.id.twitter_send）;
        状态=（EditText上）findViewById（R.id.twitter_text）;
        的userName =（的TextView）findViewById（R.id.twitter_username）;        loginButton.setVisibility（View.VISIBLE）;
        userName.setVisibility（View.GONE）;

            }
        }
    }    公共无效onLogInClicked（视图v）{
        如果（！isLogged）{
            ConfigurationBuilder建设者=新ConfigurationBuilder（）;
            builder.setOAuthConsumerKey（CONSUMER_KEY）;
            builder.setOAuthConsumerSecret（CONSUMER_SECRET）;
            配置配置= builder.build（）;
            TwitterFactory厂=新TwitterFactory（配置）;
            叽叽喳喳= factory.getInstance（）;            尝试{
                requestToken = twitter.getOAuthRequestToken（回调）;
                this.startActivity（新意图（Intent.ACTION_VIEW，
                        Uri.parse（requestToken.getAuthenticationURL（））））;
            }赶上（TwitterException E）{
                e.printStackTrace（）;
            }
        }其他{
            Toast.makeText（这一点，已经登录，Toast.LENGTH_LONG）.show（）;
        }
    }    公共无效onLogOutclicked（视图v）{
        OAuthToken =;
        OAuthSecret =;
        isLogged = FALSE;        loginButton.setVisibility（View.VISIBLE）;
        userName.setVisibility（View.GONE）;
        userName.setText（）;
        sendStatus.setVisibility（View.GONE）;
        status.setVisibility（View.GONE）;
        logoutButton.setVisibility（View.GONE）;
    }
    公共无效onSendClicked（视图v）{
        字符串文本= status.getText（）的toString（）。
        如果（text.length（）大于0）{
           新SendTwitterStatusUpdate（这一点，CONSUMER_KEY，CONSUMER_SECRET，
               OAuthToken，OAuthSecret）.execute（文本）;
        }其他{
            Toast.makeText（这一点，输入一些文字，Toast.LENGTH_SHORT）.show（）;
        }
    }}

和我的 activity_twitter.xml 文件

 ＆LT;？XML版本=1.0编码=UTF-8＆GT？;
＆LT; LinearLayout中的xmlns：机器人=http://schemas.android.com/apk/res/android
    机器人：layout_width =match_parent

        安卓的onClick =onLogOutClicked/＆GT;＆LT; / LinearLayout中＆GT;

和 SendTwitterStatusUpdate.java 文件

 进口twitter4j.Twitter;
进口twitter4j.TwitterFactory;
进口twitter4j.auth.AccessToken;
进口twitter4j.conf.ConfigurationBuilder;
进口android.content.Context;

        this.context =背景;
        this.consumerKey = consumerKey;
        this.consumerSecret = consumerSecret;
        this.accessToken =的accessToken;
        this.accessTokenSecret = accessTokenSecret;
    }    @覆盖
    保护布尔doInBackground（字符串... PARAMS）{

        }其他{
            Toast.makeText（上下文，状态未更新，Toast.LENGTH_LONG）.show（）;
        }
    }

现在，当我运行我的应用程序我得到这个窗口

和除此之外，当我点击该按钮微博登录 ...那个按钮是不是working..need帮助

}

谁能告诉我为什么我在开放的URI = getIntent（）获取空的getData（）; ... URI对象值null..thus这部分不执行

 如果（URI = NULL＆放大器;！＆安培; uri.toString（）startsWith（回调））{
            串验证= uri.getQueryParameter（oauth_verifier）;            尝试{
                的accessToken令牌= twitter.getOAuthAccessToken（requestToken，验证）;                OAuthToken = token.getToken（）;
                OAuthSecret = token.getTokenSecret（）;
                isLogged = TRUE;                loginButton.setVisibility（View.GONE）;
                userName.setVisibility（View.VISIBLE）;
                sendStatus.setVisibility（View.VISIBLE）;
                status.setVisibility（View.VISIBLE）;
                logoutButton.setVisibility（View.VISIBLE）;                用户的用户= twitter.showUser（token.getUserId（））;
                字符串username = user.getName（）;                userName.setText（登录为：+用户名）;
            }赶上（例外五）{
                Log.e（登录错误：e.getMessage（））;
            }
        }

解决方案

 看看这个演示的链接，你会得到的想法它是如何工作，然后尝试实现自己的
您可以下载两个
你只需创建你的Twitter app.That也被blogger.Follow解释它们，你会得到两把钥匙。 
  TWITTER_CONSUMER_KEY =************TWITTER_CONSUMER_SECRET =******;
 
替换您的活动内运行项目。
 第一例 
 第二个例子

First i have downloaded twitter4j-3.0.3 and put its .jar files into libs folder of my eclipse app.After that i create an app on https://dev.twitter.com/ and get all the credentials needed and gave callback url as https://google.co.in

Now my code is as follows
import twitter4j.Twitter;

Now when i run my application i got this window


and apart from that when i am clicking on that button twitter log in ...that button is not working..need help

}

can anyone tell me why i am getting null on Uri uri = getIntent().getData();...uri object value is null..thus this part is not executing   
if(uri!=null && uri.toString().startsWith(CALLBACK)) {
            String verifier = uri.getQueryParameter("oauth_verifier");

            try {
                AccessToken token = twitter.getOAuthAccessToken(requestToken, verifier);

                OAuthToken = token.getToken();
                OAuthSecret = token.getTokenSecret();
                isLogged = true;

                loginButton.setVisibility(View.GONE);
                userName.setVisibility(View.VISIBLE);
                sendStatus.setVisibility(View.VISIBLE);
                status.setVisibility(View.VISIBLE);
                logoutButton.setVisibility(View.VISIBLE);

                User user = twitter.showUser(token.getUserId());
                String username = user.getName();

                userName.setText("Logged as: " + username);
            } catch (Exception e) {
                Log.e("Login error: ", e.getMessage());
            }
        }

 解决方案 
Check out this Demo links , you will get idea how it works and then try to implement own

you can download both 
you have to just create your Twitter app.That is also explain by blogger.Follow them you will get two keys. 
TWITTER_CONSUMER_KEY="**********************";

TWITTER_CONSUMER_SECRET="********************";
Replace inside your activity and run your project.

First Example

Second Example
