从webview Android应用程序中的浏览器打开链接

Question

所以我按照post的说明进行操作，但仍然无法让我的应用程序打开应用程序内的链接。

我做了很多研究。请记住，我是开发android的新手。谁能帮我？

如果有人点击某个链接（例如：styleonem.co/about）转到该页面中的该网址，我想要做的就是打开一个意图。

现在发生的是它打开应用程序（好！）但它从不在Webview中加载URL。我以为我把它全部排序了，但我一直在寻找并试图学习这个新的应用程序界面几个星期，我仍然无法弄明白。

以下是我的代码

的AndroidManifest.xml：

    <?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="co.styleonem.styleclothingco">

                <data android:scheme="http" android:host="www.styleonem.co"/>
            </intent-filter>

        </activity>
