I want that a loading bar must be shown as page loads and when we click any link on that loaded page then also a loading bar must be shown as next clicked page loads....i am using webview.
Loading bar can be displayed by overriding onPageStarted() and onPageFinished() of webviewclient. Start displaying loading bar in onPageStarted and and make it invisible in onPageFinished.
