In a large Android project, because the client is too late to update and implement, often embedded some Web pages (in some large internet companies, PC products always run in front of the client), such as the active page, usually can be embedded in the HTML5 implementation of the page, can be adapted to the mobile phone. But these pages have a lot of links, but some of these links have been implemented by our client, such as a registered link, in fact, the client has also implemented the registration function, we do not want to continue to jump to the page registration, but open the client a registered activity, can be implemented in the following ways:


XML file, as follows:

<?xml version= "1.0" encoding= "Utf-8"? ><relativelayout xmlns:android= "http://schemas.android.com/apk/res/ Android "android:id=" @+id/rva_main "android:layout_width=" match_parent "android:layout_height=" Match_parent "a Ndroid:background= "#FFFFFF" android:orientation= "vertical" > <webview android:id= "@+id/public_webview_w Ebview "android:layout_width=" fill_parent "android:layout_height=" fill_parent "android:background=" #a Bcabc "/> <progressbar android:id=" @+id/public_webview_progressbar "style="?

The Java code is as follows:
