Android系统分享使用Intent分享文本到QQ和文本+图片到微信朋友圈及纯图到微信 – 简书

本文对应的Git项目

本文主要介绍以下功能：

简单说明-也是我当时需要要做出来的效果：

1.QQ:分享到QQ好友时，直接以发文本的方式分享出去，字数不受限制
2.WechatMoment : 分享到微信朋友圈时，需要将图片带到发送朋友圈图文发送界面直接发送分享（新版微信不支持同时带文本）
3.直接分享图片给微信好友

说到分享许多人都会使用一些第三方sdk来实现，比如“友盟分享”，“Mob分享（ShareSdk）”。

这两种分享方式需要配置许多文件和代码，虽说省去了我们一个个集成各大网站分享的sdk，但常常也会自带许多坑，具体的大家在使用的时候就会发现，我就不评价了。

QQ分享：无论是友盟或sharesdk，都无法实现直接将长文本分享到QQ好友，原因是什么？我找过他们客服，这是tencent（腾讯）公司分享sdk规定的。具体可查看：链接中的 1.13 分享消息到QQ（无需QQ登录）的参数，以QQapi上的代码进行分享以后除了文本字数有限制以外，而且其分享的样式是以链接的形式分享出去的，所以不符合我的要求。

WechatMoment微信朋友圈分享：以官方文档或以第三方通道分享时，在分享到朋友圈的时候，分享文本是设置不到文本区域的，无论你用啥方法。因为ShareSdk官方文档也说了：查看第4点（微信（好友、朋友圈、收藏））当你需要同时设置分享图片和文本时你设置的text是不显示的。

我的解决方案：（使用Intent分享）但有个缺点是，分享到平台后却不能返回到原应用，只能留在QQ或微信（除在微信分享文件-分享文件给好友可以返回到原应用）

先给大家提供个判断QQ向微信客户端是否存在的两个方法：
调用方式如：Platformutil.isInstallApp(context,PlatformUtil.PACKAGE_WECHAT);// 判断微信是否安装

之前有同学说在分享QQ和微信的时候，发现只要QQ或微信在打开的情况下，再调用分享只是打开了QQ和微信，却没有调用选择分享联系人的情况，这里，我要感觉一下@<span class="token punctuation">[</span>努力搬砖<span class="token punctuation">]</span>同学，他找出了原因。
解决办法如下：
 mActivity<span class="token punctuation">.</span><span class="token function">startActivity</span><span class="token punctuation">(</span>intent<span class="token punctuation">)</span><span class="token punctuation">;</span><span class="token operator">/</span><span class="token operator">/</span>如果微信或者QQ已经唤醒或者打开，这样只能唤醒微信，不能分享

QZone（QQ空间）

经过我反复试验，通过adb（方法：adb shell “dumpsys window | grep mCurrentFocus”）查找QQ中的空间发布说说界面是：cooperation.qzone.QzonePublishMoodProxyActivity，但始终歪能成功，在网上看到有人说是该界面没有对外开放，所以这里只能通过调用qq空间app打开发布界面进行分享内容！（强调：不是QQ内自带发布界面，是QQ空间单独的APP）。后期再研究下能否直接使用QQ内直接的界面。

在上面微信好友和朋友圈分享的过程中遇到了这样一串代码：

上面这部分代码主要功能是判断了下文件是否存在，在android版本高过7.0（包括7.0版本）当前APP是不能直接向外部应用提供file开头的的文件路径，需要通过FileProvider转换一下。否则在7.0及以上版本手机将直接crash。
这里再提供下我这里具体的逻辑：

<code class="  language-dart">常量：ShareToolUtil<span class="token punctuation">.</span>AUTHORITY <span class="token operator">--</span>写在哪儿无所谓，只要能调用到
public <span class="token keyword">static</span> <span class="token keyword">final</span> String AUTHORITY <span class="token operator">=</span> <span class="token string">"com.gudd.demo.fileprovider"</span><span class="token punctuation">;</span>
</code>
<code class="  language-jsx"><span class="token comment">// AndroidManifest需要加一个provider的标签，里面的authorities就是我们上面需要调用的一个常量</span>
<span class="token comment">// 如果你有多个module的话也没关系，所有的module只要有一个地方写了这个就行，因为app打包以后所有的AndroidManifest文件将会合并到一起</span>
<span class="token operator">&lt;</span>provider
            android<span class="token punctuation">:</span>name<span class="token operator">=</span><span class="token string">"android.support.v4.content.FileProvider"</span>
            <span class="token comment">// 再说一遍哦：这里的"com.gudd.demo"是自定义的，需要改成你们自己的名字，其实可以随便写啦。这里很重要，不能两个app使用相同的名字，否则~~嘿嘿，两个app是不能同时安装的！！</span>

上面还有个资源文件：resource=”@xml/file_paths_screencapture”

file_paths_screencapture.xml 该文件需要在AndroidManifest.xml中引用
<code class="  language-xml">//  上图是写这个文件要放的位置，随便哪个Module都没关系

     * 保存图片，并返回一个File类型的文件
     * 如今Android版本已经高达28了，但在使用该方法时，涉及到权限问题，本人在创建文件夹时遇到文件夹创建失败问题，遂将原因及解决方法记录如下：
问题：Android6.0以后，文件夹创建失败。也就是使用file.mkdirs方法.
解决方法：1.读写sdcard需要权限，但仅在manifest.xml里面添加是不够的，需要动态申请权限。2.可以将targetSdkVersion改为21或22或以下。
否则在分享过程中获取不到图片就会弹出“获取资源失败”这样的提示。

这就是我的方法，在分享微信朋友圈的时候需要注意一点，分享的图片要保存在微信可获取到的目录下，一定不能保存在/data/data/****这个内置目录中，否则将获取不到图片报“获取不到图片资源，…..”导致分享失败。

后面如果有时间我会再将新浪的分享给写进来。
今天是7月10日，距离这篇文章已经有段时间了，为了说到做到，我把新浪的也给分享出来，还是在回头看这篇文章的时候想到，原来忘记我说的新浪这回事儿了，哈哈。。。

新浪微博分享

新浪分享分为两部分，一部分指分享给好友，一部分分享到内容。看下面吧。

直接添加进入QQ群

* 调用 joinQQGroup(CXaQmSGNixYtgpaRuUlxd0CwyMhQYkd_) 即可发起手Q客户端申请加群 Android学习交流(610194891)
*
* @param key 由官网生成的key
* @return 返回true表示呼起手Q成功，返回fals表示呼起失败

以上仅是个人工作中遇到的一些问题，记录下来方便以后查阅，如有优化方法请留言。

QQ、WECHAT在打开情况下分享时只能唤醒应用却不能调用分享联系人列表情况。解决办法如下：

<code class="  language-cpp">调用开启分享界面 mActivity<span class="token punctuation">.</span><span class="token function">startActivity</span><span class="token punctuation">(</span>intent<span class="token punctuation">)</span><span class="token punctuation">;</span><span class="token comment">//如果微信或者QQ已经唤醒或者打开，这样只能唤醒微信，不能分享 </span>
