Ad banner: Manual swipe switch, auto switch, click Jump, asynchronous Load network picture

:

The banner function has automatic switch picture, click the picture can customize the event, manually swipe to switch, load the picture asynchronously

Code to speak:

Layout file:

<!--ad--<framelayout android:id= "@+id/new_recommend"                Android:layout_width= "Fill_parent" android:layout_height= "Wrap_content" > <com.cyou.cmall.ui.horizontalviewpager android:id= "@+id/viewpager" android:layou                    T_width= "Fill_parent" android:layout_height= "fill_parent"/> <linearlayout Android:id= "@+id/ll_indicator" android:layout_width= "Wrap_content" Andro id:layout_height= "Wrap_content" android:layout_gravity= "Bottom" android:orientation=            "Horizontal" android:paddingbottom= "8DP" android:paddingleft= "26dip"/> </framelayout> 

In the layout file I have customized a horizontalviewpager, which is based on the Viewpager to make some changes, the reason is because the project is used in the drop-down refresh control, the layout of the outermost layer has a scrollview, Causes ScrollView to intercept gesture events, while Viewpager does not get a swipe gesture

Here is the code for Horizontalviewpager, if you do not need to handle the swipe gesture, you can use the system's Viewpager control completely

/** * Replication This control is because in Pulltorefreshscrollview, Viewpager cannot swipe horizontally * * @author Wangwei_cs */public class Horizontalviewpager    Extends Viewpager {private Gesturedetector mgesturedetector;        Public Horizontalviewpager (context context, AttributeSet Attrs) {Super (context, attrs);    Init (context);        } public Horizontalviewpager (context context) {super (context);    Init (context);    } private void Init (context context) {Mgesturedetector = new Gesturedetector (context, new Yscrolldetector ()); } @Override public boolean dispatchtouchevent (Motionevent ev) {Boolean dispatchtouchevent = Super.dispatch        TouchEvent (EV);                if (dispatchtouchevent) {if (mgesturedetector.ontouchevent (EV)) {//Request parent class Abort event handling            Requestdisallowintercepttouchevent (TRUE);    }} return dispatchtouchevent; } class Yscrolldetector extends Simpleongesturelistener {@Override public boolean onscroll(Motionevent E1, motionevent E2, float Distancex, float distancey)        {//If we scroll closer to the horizontal direction, return true, handle it ourselves, otherwise, let go of the processing permission return (Math.Abs (Distancex) > Math.Abs (Distancey)); }}}</span>

What to do: Call the method in the program OnCreate method

    /** * Initialize recommended AD zone */private void Initrecommendad () {Horizontalviewpager Mviewpager = (horizontalview        Pager) Findviewbyid (R.id.viewpager);        Mindicatorlayout = (linearlayout) Findviewbyid (r.id.ll_indicator); Framelayout.layoutparams params = new Framelayout.layoutparams (Android.widget.FrameLayout.LayoutParams.MAT        ch_parent, Height * 24/100);        Mviewpager.setlayoutparams (params);            Adimagepageradapter mpageradapter = new Adimagepageradapter (MCXT, Imageurls, New Viewpageritemclicklistener () {                    @Override public void Onviewpageritemclick (int position) {if (imageurls.size () > 0) {                        if (imageurls.size () = = 1) {Boolean enable = Urlenable (Imageurls.get (0));                        if (enable) {handleclickevent (position);      }} else {handleclickevent (position);              }                }            }        });        list<string> lastadurls = Getlastadurls (); if (Lastadurls = = NULL | | lastadurls.size () = = 0) {//No previous ad URL information was recorded, add an invalid URL path Imageurls.add (Cons Tants.
