Android Share Intent选择器 - 与Facebook / Twitter共享文本社交媒体等

如果我只发送文字,则分享意图选择器不会将Facebook / Twitter作为选项。

只有Gmail,Skype和Evernote可供选择。

这是我的代码

Intent shareIntent = new Intent(Intent.ACTION_SEND);

shareIntent.setType("plain/text");
shareIntent.putExtra(Intent.EXTRA_TEXT, text)
startActivity(Intent.createChooser(shareIntent, "Share using"));

我尝试过不同的setType()组合,包括“text / *”,“text / html”,并在putExtra中传递HTML文本,如下所示:

shareIntent.putExtra(Intent.EXTRA_TEXT, Html.fromHtml("<p>This is the text that will be shared.</p>"));

当我使用“text / plain”时,Facebook会作为一个选项出现,但选择它时文本不会加载。但该文本确实加载了Twitter,电子邮件和短信。

还有其他人遇到过这个问题吗?

当我分享图片时,没有任何问题,Facebook上还有其​​他社交媒体应用程序可供选择。

根据文档,它也应该是“text / plain”而不是“plain / text”。

答案 1 :(得分:3)

这取决于每个应用程序定义的intent过滤器 例如,如果我添加了intent-filter        android.intent.action.send

如果我从图库中选择单张图片,我的应用程序将显示在列表中。但是,如果我选择多个,我的应用程序将不会显示,因为我没有为android.intent.action.send_multiple添加intent-filer

所以这取决于facebook过滤的意图。您需要查看发行说明或帮助或开发人员页面。

Facebook问题是facebook权限的限制。使用facebook API

通过Twitter分享:

Intent shareIntent = new Intent(android.content.Intent.ACTION_SEND);

shareIntent.putExtra(android.content.Intent.EXTRA_TEXT, (String)v.getTag(R.drawable.ic_launcher));

//查找推特包名称----&gt;&gt;

   PackageManager pm = v.getContext().getPackageManager();

   List<ResolveInfo> activityList = pm.queryIntentActivities(shareIntent, 0);

     for (final ResolveInfo app : activityList) 
      {
        if ("com.twitter.android.PostActivity".equals(app.activityInfo.name))
          {
             final ActivityInfo activity = app.activityInfo;
             final ComponentName name = new ComponentName(activity.applicationInfo.packageName, activity.name);
             shareIntent.addCategory(Intent.CATEGORY_LAUNCHER);
             shareIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED);
             shareIntent.setComponent(name);
