Android WebView Shows Site Differently Than Chrome

My app has a list view with data from an RSS feed. When a row is selected it then shows that article in a web view. It loads the page but it doesn't load the full mobile site like Chrome does. I'm putting screenshots of an article loaded in the web view of my app and the same page in Chrome. Any ideas?

Here it is in Chrome: 在此处输入图片说明

Here it is in my web view: 在此处输入图片说明

The server inspects the user agent header string and sends a smaller version of the page when it thinks the request comes from a mobile phone.

It seems, this logic is not working perfectly.
