接入Twitter

具体查看官方提供的说明文档

创建应用

1、创建应用
进入网址：https://apps.twitter.com/ 创建应用，获得key，secret，勾选
Allow this application to be used to Sign in with Twitter

2、在Callback URLs添加"twittersdk://"
不然没有安装Twitter App的时候会返回错误。

工程配置

1、build.gradle(app)引入库文件

dependencies {
  compile 'com.twitter.sdk.android:twitter-core:3.1.1'
}

2、build.gradle(project) 配置jcenter()

repositories {
  jcenter()
}

3、strings添加consumer_key和consumer_secret

<string  name="twitter_consumer_key">xxxxxxxxxx</string
<string  name="twitter_consumer_secret">xxxxxxxxxx</string>

代码调用

一、使用TwitterLoginButton

1、初始Twitter

private void initTwitter() {
    String key = getString(R.string.twitter_consumer_key);
    String secret = getString(R.string.twitter_consumer_secret);
    
    TwitterConfig config = new TwitterConfig.Builder(this)
    .logger(new DefaultLogger(Log.DEBUG))
    .twitterAuthConfig(new TwitterAuthConfig(key, secret))
    .debug(true)
    .build();
    Twitter.initialize(config);
}

2、配置XML文件

<com.twitter.sdk.android.core.identity.TwitterLoginButton
    android:id="@+id/login_button"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerInParent="true"/>

3、设置login和回调

private void twitterButton () {
    loginButton = (TwitterLoginButton) findViewById(R.id.login_button);
    loginButton.setCallback(new Callback<TwitterSession>() {
        @Override
        public void success(Result<TwitterSession> result) {
            // Do something with result, which provides a TwitterSession for making API calls
            // result里面包含了用户的信息，我们可以从中取出token，tokenSecret
            // 如果我们有自己的后台服务器，发送这两个到我们自己的后台，后台再去验证）
            TwitterAuthToken authToken = result.data.getAuthToken();
            
            String token = authToken.token;
            String tokenSecret = authToken.secret;
            String userName = result.data.getUserName();
            String userId = result.data.getUserId()+"";
            
            Log.i("token",token);
            Log.i("tokenSecret",tokenSecret);
            Log.i("userName",userName);
            Log.i("userId",userId);
            
        }
        
        @Override
        public void failure(TwitterException exception) { // Do something on failure
            exception.printStackTrace();
        }
    });
}

4、处理onActivityResult

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    
    // Pass the activity result to the login button.
    if(loginButton!=null) {
        loginButton.onActivityResult(requestCode, resultCode, data);
    }
}

使用自定义Button

1、初始化同上面

2、配置xml
设置一个自定义的Button

3、设置调用和回调

private void customerButton () {
    mbutton = (Button)findViewById(R.id.login_customer_button);
    mbutton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            authTwitter();
        }
    });
}

private void authTwitter() {
    
    mTwitterAuthClient = new TwitterAuthClient();
    mTwitterAuthClient.authorize(this, new Callback<TwitterSession>() {
        @Override
        public void success(Result<TwitterSession> result) {
            TwitterAuthToken authToken = result.data.getAuthToken();
            
            String token = authToken.token;
            String tokenSecret = authToken.secret;
            String userName = result.data.getUserName();
            String userId = result.data.getUserId()+"";
            
            Log.i("token",token);
            Log.i("tokenSecret",tokenSecret);
            Log.i("userName",userName);
            Log.i("userId",userId);
        }
        
        @Override
        public void failure(TwitterException exception) {
            exception.printStackTrace();
        }
    });
    
}

4、处理onActivityResult

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if(mTwitterAuthClient!=null) {
        mTwitterAuthClient.onActivityResult(requestCode,resultCode,data);    
    }
}

详情请参考demo工程

常见问题

一、返回错误：Callback URL not approved for this client application

Invalid json:?xml version="1.0" encoding="UTF-8"?Callback URL not approved for this client application.
Approved callback URLs can be adjusted in your application settings

这个是在没有安装Twitter App的时候，调用登录会默认加载网页版的登录页面。

解决方法：在App设置那边的Callback URLs添加："twittersdk://"
