In development we often need to set our application to full screen, there are two ways, one is set in the code, the other way is in the configuration file to change!
First, set in code:
Copy Code code as follows:
Package com.android.tutor;

It is recommended that you use the first method so that you will be alerted when you install the program:

This article is an example of the implementation of Android programming WebView Adaptive Full-screen method. Share to everyone for your reference, specific as follows:
First type:
Settings.setusewideviewport (true);
Settings.setloadwithoverviewmode (TRUE);
The second type:
websetting settings = Webview.getsettings ();
Settings.setlayoutalgorithm (Layoutalgorithm.single_column);
//flipper.startflipping ();
Then load a Boolean ontouchevent (Motionevent event)
Set a global variable private Float startx;//the position of the finger when it falls
Get by Event.getaction ()
Case motionevent.action_down://Finger drop
{startx = Event.getx ();} --> gets the first horizontal coordinate case
motionevent.action_up://fingers leave
{by judging the event.getx ()-startx>100 to the right to slide, then animate, and show the front side
Startx-event.getx ()
