意图过滤器和android：pathPattern [英] Intent Filters and android:pathPattern

问题描述

在我的应用程序，我想处理使用以下模式链接：

In my application, I want to handle links that use the following pattern:

方案：//主机/文件夹1 /文件夹2 / folder3 / folder4 /条

我得到它暂时无法工作，通过使用以下内容：

I got it to work temporarily, by using the following:

<intent-filter>
    <data android:scheme="http" />
    <data android:host="www.laprensa.com.ni" />
    <action android:name="android.intent.action.VIEW" />
    <category android:name="android.intent.category.DEFAULT" />
    <category android:name="android.intent.category.BROWSABLE" />
</intent-filter>

但是，正如你可能想象，打开与方案开头的链接：//主机，我想确保我只能拿起那些有如上所述图案，其中所述页是主机内4个文件夹。

However, as you may imagine that opens any link that starts with scheme://host, and I want to make sure I only pick up on those that have the above stated pattern, where the page is 4 folders inside the host.

另一个小问题是，文件夹的名称是绝不相同，因此，我不能简单地用的android：路径。另外值得一提的是，的android：路径preFIX 是不一样的，因为前三个文件夹中日期相关的。

Another little problem is that the folder names are never the same, and therefore I cannot simply use android:path. It's also worth noting that the android:pathPrefix is not the same, as the first three folder are date related.

例如，网址是strucutred是这样的：

For instance, the urls are strucutred something like this:

方案：//主机/年/月/日/ articleType /条

我一直在阅读关于如何使用 Android版Google文档和问题：pathPattern ，但我真的不明白我应该键入

I've been reading the docs and questions on how to use android:pathPattern but I really don't understand what I'm supposed to type in.

任何想法？

谢谢！

修改

建议后，我想：

的android：pathPattern =/.*/.*/.*/.*/.*

这里，每个'*'重新presented一个文件夹，但似乎仍然拿起不在文章的其他网址。例如，下面是两个不同的网址：

Where each '.*' represented a folder but that seems to still pick up the other URLs that are not articles. For example, here are two different urls:

网址我想处理：

http://www.laprensa.com.ni/2013/05/10/vida/145996-lionel-richie-defiende-a

网址我不希望处理

Url I don't want to handle

http://www.laprensa.com.ni/2013/05/10/vida/

我想这里的问题是，它们都具有水平相同数量的，唯一的区别是，一个后，去年/，任何其他居然有东西想法我能试试吗？我也尝试增加一个'/.*但完全停止工作和停止的应用程序处理的任何链接期间：（

I guess the problem here is that they both have the same amount of levels, the only difference is that one actually has something after that last '/', any other ideas I can try? I did try adding one more '/.*' but that stopped working completely and the app stopped handling any links period :(

推荐答案

您应该添加完全的android：pathPattern 属性来配置你定义。
正如 Android文档， Android的：pathPattern 可以包含以下通配符构建简化常规的前pressions：

You should add exactly the android:pathPattern attribute to configuration you defined. As reported in Android documentation, android:pathPattern can contain following wildcards for building simplified regular expressions:

• 星号（*）的0序列匹配到马上preceding性格许多发生。


• 句点后跟一个星号（*）的0任何序列匹配的字符。

在您的情况：

<data android:scheme="http"
      android:host="www.laprensa.com.ni"
      android:pathPattern="/.*/.*/.*/.*/.*" />

如果每个*重新present文件夹名称。

Where each .* represent a folder name.
