关于twitter这一块，自发这篇博文之后有很多人问我，有的验证成功了不跳转，或者其它原因什么的，我看了一下，这篇博文里面有写呀，下面以红色粗体文字注明一下

刚进公司，叫我先学习twitter和facebook，就类似于国内的微博，或者分享功能，点击某个按钮，出来一个提示框，可以分享到某些地方，这里实现的就是分享到twitter，当然得要使用代理，因为这是给老外做的，所以得符合他们的习惯

先说一下实现的功能吧，首先运行的时候，会检查是否登陆twitter（通过sharedpreference文件保存登陆状态），如果没有登陆的话会跳转到twitter的登陆认证页面，提示用户输入用户名和密码，这些就是oauth认证的步骤，不懂的看这儿 www blogs /and_he/archive/2011/05/22/2053477.html

做过新浪微博的都应该知道，首先要申请成为开发者，创建自己的应用，然后会给你一些比如consumer key和consumer secret之类的东西，这些东西要先记下来，代码里面要用到的，其余的不啰嗦了，只是要注意一点，创建twitter应用的时候造成不能忘了填那个callback url，我当初就没填，结果整了几天都整不出来结果，也算是我的一点经验吧，下面贴代码，以便于以后查阅

首先我们要用到twitter封闭好的一些包，这里用到两个twitter4j-core-android和twitter4j-media-support-android，百度一下就出来了

twitter曾经举行了自己四年以来的第一场开发者大会。而这场名为“flight”的大会，也是以后它的年度惯例。

这次大会的主题也完全围绕开发者进行。大会的焦点是一个名叫fabric的新sdk，里面包括三个开发者工具包：面向twitter本身的 twitter kit、面向twitter广告网络的mopub，以及基于twitter 2013年收购的移动应用崩溃分析工具crashlytics的crashlytics kit。

我还是先贴上twitter登录的官方网站： dev.twitter /twitterkit/android/log-in-with-twitter，不过都是英文，当然，我们还需要爬过一堵墙才能够上网。

首先我们要先去注册twitter开发者账号，并且创建应用， apps.twitter .

点击右上角创建应用：

然后会进入下图：

我们需要填入应用的名称，还有应用的描述，至于website，下面解释的意思大概是：您的应用程序的可公开访问的8797威尼斯老品牌主页，用户可以下载，使用或查找有关您的应用程序的更多信息。该完全限定的url用于源应用程序创建的tweets，并将显示在面向用户的授权屏幕中。 （如果你还没有url，只需在这里放置一个占位符，但记住稍后再改变它。）

?

?

应用创建完成之后，我们可以进入应用查看相关的设置，点击keys and access tokens，可以看到consumer key (api key)和consumer secret (api secret)，这两个需要用到

?

好了，创建应用就到这里，接下来讲讲如何集成到我们的项目：

（一）首先我们要集成twitter相关的sdk，8797威尼斯老品牌官网上写得比较多，如果仅仅需要登录功能，那么就只需要

在build.gradle(app)里面写上

dependencies {

compile 'com.twitter.sdk.android:twitter-core:3.1.1'

}

在build.gradle(project)的?repositories里写上

repositories {

jcenter()

}

（二）在我们的资源文件里面添加api key，这个api key在twitter的应用管理可以看到，就是我们上面说的那两个

xxxxxxxxxxx

xxxxxxxxxxx

?

（三）建立一个自定义的application，在oncreate()方法里面初始化

twitter.initialize(this);

twitterconfig config = new twitterconfig.builder(this)

.logger(new defaultlogger(log.debug))

.twitterauthconfig(new twitterauthconfig("consumer_key", "consumer_secret"))

.debug(true)

.build();

twitter.initialize(config);

?

（四）我们可以用twitter提供好的登录按钮，当然也可以自定义，接下来会讲。

android:id="@ id/login_button"

android:layout_width="wrap_content"

android:layout_height="wrap_content" />

?

（五）在代码中：

loginbutton = (twitterloginbutton) findviewbyid(r.id.login_button);

loginbutton.setcallback(new callback() {

@override

public void success(result 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 appid = getresources().getstring(r.string.twitter_app_id); string tokensecret = authtoken.secret;

}

@override public void failure(twitterexception exception) { // do something on failure } });

@override

protected void onactivityresult(int requestcode, int resultcode, intent data) { super.onactivityresult(requestcode, resultcode, data); // pass the activity result to the login button. loginbutton.onactivityresult(requestcode, resultcode, data); }

?

?如果登录按钮是在fragment中的话，那么onactivityresult应该用如下代码：

应该

@override

protected void onactivityresult(int requestcode, int resultcode, intent data) {

super.onactivityresult(requestcode, resultcode, data);

// pass the activity result to the fragment, which will then pass the result to the login

// button.

fragment fragment = getfragmentmanager().findfragmentbyid(r.id.your_fragment_id);

if (fragment != null) {

fragment.onactivityresult(requestcode, resultcode, data);

}

}

其余的可以参考8797威尼斯老品牌官网

接下来讲的一个是自定义登录按钮，其实有一个妙计，请看下面界面代码：

android:id="@ id/framelayout"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_below="@ id/facebook"

android:layout_margintop="@dimen/login_button_margin_bottom"

android:layout_centerhorizontal="true">

android:id="@ id/login_button"

android:layout_width="@dimen/button_width"

android:layout_height="@dimen/button_height"

android:layout_margintop="@dimen/button_margin_bottom"

android:visibility="gone"/>

android:id="@ id/login_image"

android:layout_width="@dimen/button_width"

android:layout_height="@dimen/button_height"

android:src="@drawable/twitter" />

然后代码中：

@override

public void onclick(view view) {

switch (view.getid()){case r.id.login_image:

loginbutton.performclick();

break;

default:

break;

}

}

即，点击我们自定义的按钮的时候，让twitter登录按钮执行点击操作。

先到这里，以后慢慢补充。
