推荐答案

是的，你可以做到这一点。您可以在您的应用程序作为处理你自己的方案（计划）注册的活动。应用程序清单将是这样的：

Yes, you can do that. You register an activity in your app as the handler for your own protocol (scheme). The application manifest will have something like:

    <activity android:name=".SchemeActivity"
        android:label="@string/app_name">
        <intent-filter>
            <action android:name="android.intent.action.VIEW" />
            <category android:name="android.intent.category.DEFAULT" />
            <category android:name="android.intent.category.BROWSABLE" />
            <data android:scheme="myownprotocol" />
        </intent-filter>
    </activity>

这个活动将不会显示或到应用程序启动器的图标，所以你可能有除了这一个普通的活动。

This activity will not be displayed or get an icon in the application launcher so you probably have an "ordinary" activity in addition to this one.

现在，任何网页可以有一个像下面的链接：

Now, any web page can have link like the following:

<a href="myownprotocol://12345">Sample link</a>

通过安装应用程序，你应该能够点击在网络浏览器这样的链接，并有我的样本中SchemeActivity显示。该活动在里面，你可以获取整个链路（并解析附加ID /数据或任何你必须有）由：

With the application installed, you should be able to click such a link in the web browser and have the SchemeActivity in my sample be shown. Inside that activity, you can fetch the whole link (and parse the additional id/data or whatever you have there) by:

String fullUrl = getIntent().getDataString();
