Packaged Android monitor finger left and right sliding screen event class sharing _android

The right and left sliding is the most commonly used mobile phone, this simple encapsulation a bit, later directly to use on it.

Just a few lines is all it takes, and the following class is encapsulated.

 package com.example.test;
Import Android.os.Bundle;
Import android.app.Activity;
Import Android.content.Context;
Import Android.util.Log;

Import Android.widget.RelativeLayout; public class Mainactivity extends activity {@Override protected void onCreate (Bundle savedinstancestate) {Super.oncre
 Ate (savedinstancestate); Setcontentview (R.layout.activity_main);//The XML here is a blank layout//view Relativelayout view of the left and right sliding events (relativelayout
 
 ) This.findviewbyid (r.id.layout);
 Setlongclickable is a necessary view.setlongclickable (true);
 View.setontouchlistener (This) (new Mygesturelistener); /** * Inherits Gesturelistener, overrides left and right methods * * Private class Mygesturelistener extends Gesturelistener {public mygest
 Urelistener (context) {super (context);
  @Override public Boolean Left () {LOG.E ("test");
 return Super.left ();
  @Override public Boolean Right () {LOG.E ("test", "slide to starboard");
 return Super.right (); }
 }
}
