不使用浏览器打开网址

Question

我正在寻找一种在应用程序上而不是在浏览器中打开 URL 的方法。我发现了同样的问题here 并且有人提到如果不使用浏览器就无法从应用程序中打开 url。有人可以建议或展示一种无需使用浏览器即可打开网址的方法吗？

任何帮助将不胜感激。提前致谢。

Answer 1

您可以使用网页视图在您的应用中打开网址。这是关于它的官方谷歌文档http://developer.android.com/reference/android/webkit/WebView.html

Answer 2

您可以在新的活动或片段中使用 webview

如果你想要样品然后问我

从您的主要活动或活动中，您有按钮放置您的意图代码以打开 webview 活动并在通过意图单击按钮时传递 url

并在 webview 活动中以字符串形式获取它并在加载 url 中使用它
