Chrome 自定义标签、隐藏关闭按钮和处理设备后退按钮

Question

I am using chrome custom tabs in Xamarin android application and opening a google page url (it would be my website url in future), I want to know if it possible to hide the close button? currently if user closes the custom tab, a blank page is shown, I don't want user to close the tab.

Secondly if user presses the device back button, same thing happens, a blank page is shown.

What are the possible things I can do?

Answer 1

In terms of the close button, no, you can not remove it. You can change it from an X to a back arrow, but that is it.

Chrome Custom Tabs is not designed to be used as an embedded browser, but as a way to open content that is external to yours, an Auth2 process, to show a link that is not within your domain, etc.. and thus keep the user within your app experience, once they are done with that external content, they return to your app via the close button or the soft/hard back button.

If you are looking for an embedded browser, Google/Chrome's dev team still recommend using a WebView .

If you want the user to feel like Custom Tabs is a modal dialog, use the default “X” button. If you want the user to feel the Custom Tab is part of the application flow, use the back arrow.

Answer 2

Instead of using custom tabs you can use WebView to load your web pages. While you can't remove the 'X' arrow, you can create an activity with a WebView as its XML element and use the WebView to load your web pages.
