HTMLViewerActivitypublic class HTMLViewerActivity extends android.app.Activity | Wraps a WebView widget within an Activity. When launched, it uses the
URI from the intent as the URL to load into the WebView.
It supports all URLs schemes that a standard WebView supports, as well as
loading the top level markup using the file scheme.
The WebView default settings are used with the exception of normal layout
is set.
This activity shows a loading progress bar in the window title and sets
the window title to the title of the content. |
