背景

Android的M presents一种新的方式来处理选定的文本（链接的此处），甚至从你的应用程序之外。文本选择可处理为这样：

我知道这是可以从应用程序之外处理选定的文本，因为如果我去到Web浏览器（或任何其他地方，可以让文本选择），我可以看到，我可以使用API演示应用程序，以办理选定的文本。

问题

我看不到很多关于如何做到这一点的信息。

问题

我应该在code（和明显的），以便能够从应用程序之外处理所选文本添加？ 是否有可能限制选择某些类型的文本？例如，提供给显示该应用仅当文本类型为有效的电话号码？ 解决方案

首先，要澄清一个问题：在一个M模拟器，如果你选中的文字，你会看到新的浮动的行动模式。如果单击溢图标，你会看到API DEMOS显示：

点击，带来了从API演示应用程序的活动，显示了突出显示的文本：

更换的字段中的值，然后点击按钮作为替换为任何你强调了把你替换文本。

警告：下面的解释是检查API演示code和并购开发preVIEW文档。这是非常可能的，这将收到中号船为Realz的改变。情况因人而异，除非你用公制，在这种情况下YKMV。

有关活动，正在接收文本，支持 ACTION_PROCESS_TEXT 为意图的行动。 EXTRA_PROCESS_TEXT 将举行一些文本，或 EXTRA_PROCESS_TEXT_READONLY 将举行，如果文本是只读的。该活动将通过 startActivityForResult调用（）。结果意图可以有自己的 EXTRA_PROCESS_TEXT 值，这将是替换文本。

因此​​，具体的问题：

  

我应该在code（和明显的），以便能够从应用程序之外处理所选文本添加？

见上面。请注意，API演示活动（ ProcessText ）有这个＆LT;意向滤光器＆gt; ：

 ＆LT;意向滤光器＆gt;
            ＆lt;作用机器人：名称=android.intent.action.PROCESS_TEXT/＆GT;
            ＆LT;类机器人：名称=android.intent.category.DEFAULT/＆GT;
            ＆lt;数据机器人：MIMETYPE =text / plain的/＆GT;
        ＆所述; /意图滤光器＆gt;
 

本文档不讨论一个MIME类型。我没有运行任何实验，以确定MIME类型是必需的，而且我们还有什么可能会得到（的text / html 的东西，有跨度？）。

  

是否有可能限制选择某些类型的文本？例如，提供给显示该应用仅当文本类型为有效的电话号码？

这似乎不能够提供的文档。话虽这么说，这肯定是一个合理的想法（例如，在清单公布一个正则表达式，或多个正则表达式，通过元数据文本必须匹配）。

Background

Android M presents a new way to handle selected text (link here), even from outside of your app . Text selection can be handled as such:

I know it's possible to handle the selected text from outside the app, because if I go to the web browser (or any other place that allows text selection), I can see that I can use the "API demos" app to handle the selected text.

The problem

I can't see a lot of information about how to do it.

The question

What should be added in code (and manifest) to be able to handle the selected text from outside the app ? Is it possible to limit the selection to certain types of texts ? For example, offer to show the app only if the text type is a valid phone number ?

解决方案

First, to clarify the question: On an M emulator, if you highlight text, you will see the new floating action mode. If you click the overflow icon, you will see "API DEMOS" show up:

Clicking that brings up an activity from the API Demos app, showing the highlighted text:

Replacing the value in the field and clicking the button puts your replacement text in as a replacement for whatever you had highlighted.

WARNING: The following explanation is from inspecting the API Demos code and the M Developer Preview documentation. It is very possible that this will change before M ships for realz. YMMV, unless you use the metric system, in which case YKMV.

The activity in question, that is receiving the text, supports ACTION_PROCESS_TEXT as the Intent action. EXTRA_PROCESS_TEXT will hold some text, or EXTRA_PROCESS_TEXT_READONLY will hold it if the text is read-only. The activity will be invoked via startActivityForResult(). The result Intent can have its own EXTRA_PROCESS_TEXT value, which will be the replacement text.

So, to the specific questions:

What should be added in code (and manifest) to be able to handle the selected text from outside the app ?

See above. Note that the API Demos activity (ProcessText) has this <intent-filter>:

        <intent-filter >
            <action android:name="android.intent.action.PROCESS_TEXT"/>
            <category android:name="android.intent.category.DEFAULT" />
            <data android:mimeType="text/plain" />
        </intent-filter>

The documentation does not discuss a MIME type. I have not run any experiments to determine if the MIME type is required, and what else we might get (text/html for stuff that has spans?).

Is it possible to limit the selection to certain types of texts ? For example, offer to show the app only if the text type is a valid phone number ?

That wouldn't seem to be possible given the documentation. That being said, it's certainly a reasonable idea (e.g., advertise a regex, or multiple regexes, via metadata in the manifest that the text must match).
