android - Getting error in viewpager adapter,java.lang.IllegalStateException: The specified child already has a parent -

i trying use viewpager images shows 1 picture if slides crashes, saying java.lang.illegalstateexception: specified child has parent. must call removeview() on child's parent first. adapter code is:

public class newdemoadapter extends pageradapter {     public arraylist<integer> imagelist;     public arraylist<string> lines;     public context context;     private imageview imageview;     private bitmapfactory.options bounds;     private viewgroup viewpager;     private bitmap cropimg;     private layoutinflater minflater;      public newdemoadapter(context context, arraylist<integer> imagelist, arraylist<string> line) {          this.imagelist = imagelist;         this.lines = line;       }       @override     public int getcount() {         return imagelist.size();     }      public int getitemposition(object object) {         return position_none;     }      @override     public boolean isviewfromobject(view view, object object) {         return view == ((linearlayout) object);     }      @override     public object instantiateitem(viewgroup container, final int position) {          minflater = layoutinflater.from(appcontroller.getappcontext());         final view itemview = minflater.inflate(r.layout.demolayout,container,false);          imageview imageview = (imageview) itemview.findviewbyid(r.id.myimage);         textview textview = (textview) itemview.findviewbyid(r.id.line);         textview.settext(lines.get(position));         imageview.setimageresource(imagelist.get(position));         ((viewpager) container).addview(imageview, 0);          return itemview;     }      @override     public void destroyitem(viewgroup container, int position, object object) {         ((viewpager) container).removeview((imageview) object);         ((viewpager) container).removeview((textview) object);     }  } 

the issue line

((viewpager) container).addview(imageview, 0); 

imageview (r.id.image) has parent itemview , means can't have viewpager parent. change

((viewpager) container).addview(imageview, 0); 

to

((viewpager) container).addview(itemview, 0); 

edit

@override public void destroyitem(viewgroup container, int position, object object) {     container.removeview((view) object); }
