Android 如何筛选特定应用程序的操作\发送意图（并为每个应用程序设置不同的文本）
在使用“发送意向”操作时，您如何筛选出特定的应用程序？这个问题已经以各种方式提出，但我无法根据给出的答案收集解决方案。希望有人能帮忙。我想提供在应用程序中共享的功能。接下来，我更喜欢使用意图，而不是使用Facebook/Twitter API 使用ACTION_SEND intent进行共享很好，但问题是（1）我不希望每个共享选项都出现，我宁愿将其限制在FB、Twitter和电子邮件上，以及（2）我不想在每个共享应用程序上共享相同的内容。例如，在我的推特分享中，我将包括一些提及和hashtags，将其限制为140个字符或更少，而facebook分享将包括一个链接和一个功能图片 是否可以限制发送（共享）意图的操作选项？我已经看过一些关于使用PackageManager和QueryInputActivities的内容，但是还没有弄清楚PackageManager和ACTION_SEND intent之间的联系 或 如果我可以使用ACTION_SEND intent直接进入facebook或twitter，而不是弹出对话框，那么我的问题也可以解决，而不是过滤共享应用程序。如果是这样的话，那么我可以创建自己的对话框，当他们点击“Facebook”时，创建一个特定于Facebook的意图，然后直接发送到Facebook。Twitter也是如此Android 如何筛选特定应用程序的操作\发送意图（并为每个应用程序设置不同的文本）,android,android-intent,android-sharing,Android,Android Intent,Android Sharing,在使用“发送意向”操作时，您如何筛选出特定的应用程序？这个问题已经以各种方式提出，但我无法根据给出的答案收集解决方案。希望有人能帮忙。我想提供在应用程序中共享的功能。接下来，我更喜欢使用意图，而不是使用Facebook/Twitter API 使用ACTION_SEND intent进行共享很好，但问题是（1）我不希望每个共享选项都出现，我宁愿将其限制在FB、Twitter和电子邮件上，以及（2）我不想在每个共享应用程序上共享相同的内容。例如，在我的推特分享中，我将包括一些提及和hashtag
还是不可能？Facebook和Twitter API是唯一的方法吗？如果您想要定制选项，那么您不应该依赖android提供的默认对话框来执行此操作 你需要做的是推出你自己的。您需要查询处理所需操作的包，然后根据回复应用筛选和自定义文本 具体来说，我们来看看这个类的方法。您构建将启动默认对话框的意图（ACTION_SEND intent），将其传递给此方法，您将收到一个对象列表，其中包含可以处理该意图的活动的信息。使用它，你可以选择你想要的 一旦你建立了你想要展示的软件包列表，你需要建立你自己的列表对话框（最好是一个带有对话框主题的活动），它将显示这个列表
但需要注意的是，很难使自定义对话框看起来像默认对话框。问题是该对话框中使用的主题是内部主题，应用程序无法使用。您可以尝试使其与本地应用程序尽可能相似，也可以选择完全定制的外观（许多应用程序都可以像gallery应用程序等这样做）找到一个适合我的解决方案（请参阅第一个答案的第三条注释）。此代码查找有效的twitter客户端并使用它发布推文。注意：它并没有给你们一个使用各种Twitter客户端的意图，并允许你们选择 使用twitter共享：
Intent shareIntent = findTwitterClient();

startActivity(Intent.createChooser(shareIntent, "Share"));
