问题描述
我一直在试图把一个后退按钮进度条在一个web视图并继续使用了Android默认的Web浏览器中我的应用程序的URL负载来代替。
如果我设法保持到浏览应用程序内,并保持后退按钮,进度条一直没有出现,如果我设法得到进度条显示了code在底部shouldoverideurl拿出从未读过和默认的浏览器启动,我尝试了所有的谷歌教程和解决方案,但他们没有工作。我目前正在使用谷歌..谁能帮助??

I have been trying to put a back button progress bar in a webview and keep the url loading within my app instead of using the android default web browser.
If I manage to keep to browsing within the app and keep the back button the progress bar never shows up if I manage to get the progress bar to show up the code at the bottom for shouldoverideurl come up never read and the default browser launches, I tried all the google tutorials and solution but none of them work. I am currently using google.. Can anyone help??
