1, first to create an activity, in the activity of the OnCreate function we set it to full screen, then set the activity of the width of the full screen *0.9, and then set the background image is translucent. 9 images. This is already a non-full-screen form.

This.requestwindowfeature (Window.feature_no_title); This.getwindow (). SetFlags (WindowManager.LayoutParams.FLAG_ Fullscreen,windowmanager.layoutparams.flag_fullscreen); Setcontentview (R.layout.activity_webview); WindowManager Windowmanager=getwindowmanager ();D isplay display=windowmanager.getdefaultdisplay (); Layoutparams Params=getwindow (). GetAttributes ();p arams.height= (int) (Display.getheight () *0.9);p arams.width= (int) (Display.getwidth () *0.9);p Arams.alpha=1.0f;getwindow (). SetAttributes (params), GetWindow (). Setgravity ( Gravity.center); GetWindow (). Setbackgrounddrawableresource (R.DRAWABLE.WEBVIEWBG);
