android - ViewPager behaves in an unexpected way -

my goal implement guide/how-to-use-app activity in app, users can flip between predefined set of views. so, decided use viewpager.

this how did in guideactivity:

mpager = (viewpager) findviewbyid(r.id.pager); madapter = new guideadapter(getbasecontext()); mpager.setadapter(madapter); 

and implementation of pageradapter:

class guideadapter extends pageradapter {      private context context;       protected static final int[] slides = new int[] {          r.drawable.page1, r.drawable.page2, r.drawable.page3 };      public guideadapter(context context) {         this.context = context;     }     @override     public view instantiateitem(viewgroup container, int position) {         imageview image = new imageview(container.getcontext());         image.setimageresource(slides[position]);         container.addview(image, layoutparams.wrap_content,                 layoutparams.wrap_content);         return image;     }      @override     public void destroyitem(viewgroup collection, int position, object view) {         ((viewpager) collection).removeview((view) view);     }     @override     public int getcount() {         return slides.length;     }     @override     public boolean isviewfromobject(view arg0, object arg1) {         return true;     } } 

the problem is, images drawn in top of each other. if scroll left right, see no images. if scroll back, images shown second disappear. bottom line: viewpager behave in unexpected way!

i overridden four required methods in pageradapter. i'm not sure did wrong think has instantiateitem() and/or destroyitem().

any ideas?

this needed:

@override public boolean isviewfromobject(view view, object object) { return view == object; }
