here mainactivity.java

public class mainactivity extends activity {     context ctx;     int imagesarray[];     gridviewcontent adapter;     list<integer> pictures;     boolean flage=false;     int img1=-1,img2=-1;     public int originalarray[] = { r.drawable.sample_0, r.drawable.sample_1,             r.drawable.sample_2, r.drawable.sample_3,r.drawable.sample_0, r.drawable.sample_1,             r.drawable.sample_2, r.drawable.sample_3 };      @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.main);         shufflearray();          adapter= new gridviewcontent(this);          final gridview grid = (gridview) findviewbyid(r.id.gv_memory);         grid.setadapter(new gridviewcontent(this));     }     private void shufflearray() {         // todo auto-generated method stub         pictures= new arraylist<integer>();         (int index = 0; index < originalarray.length; index++)         {             pictures.add(originalarray[index]);         }         collections.shuffle(pictures);      }     public class gridviewcontent extends baseadapter {         private context context;          //abstract change();          public int picturearray[]={                 r.drawable.question,                 r.drawable.question,                 r.drawable.question,                 r.drawable.question,                 r.drawable.question,                 r.drawable.question,                 r.drawable.question,                 r.drawable.question,                 };         public gridviewcontent(context c){             context=c;          }          @override         public int getcount() {             // todo auto-generated method stub             return (picturearray.length);         }          @override         public object getitem(int position) {             // todo auto-generated method stub             return picturearray[position];         }          @override         public long getitemid(int position) {             // todo auto-generated method stub             return 0;         }          @override         public view getview(final int position, view convertview, viewgroup arg2) {             // todo auto-generated method stub             convertview=layoutinflater.from(context).inflate(r.layout.main, null);             final imageview myimage=new imageview(context);             myimage.setimageresource(picturearray[position]);             //myimage.setimageresource(pictures.get(picturearray[position]));             myimage.setscaletype(imageview.scaletype.center_inside);             myimage.setlayoutparams(new gridview.layoutparams(70, 70));             myimage.setonclicklistener(new onclicklistener() {                  @override                 public void onclick(view v) {                 //  int post1,post2;                      myimage.setimageresource(pictures.get(position));                  if(flage==false)                 {                  img1=pictures.get(position);                  flage=true;                  }else if(flage==true){                     //post2=position;                 img2=pictures.get(position);                 checkresult();                 //notifydatasetchanged();                 flage=false;                 }                 //else if(f)                 }             });              return myimage;         }      }     public void checkresult() {         if(img1==img2)         {             //pictures.remove(post2);              adapter.notifydatasetchanged();              toast.maketext(mainactivity.this, "congratualatin !!!!", toast.length_long).show();         }         else{             toast.maketext(mainactivity.this, "sorry!!!!", toast.length_long).show();             final gridview grid = (gridview) findviewbyid(r.id.gv_memory);             grid.setadapter(new gridviewcontent(this));         }      } } 

you try , remember index of gridview item clicked. when second click occurs, check remembered index. if populated (meaning user clicked on arbitrary image once), extract both drawables adapter , check if equal. if are, remove them adapter , update it. not forget reset remembered index.

in code, might this:

int firstclickindex = -1;  grid.setonitemclicklistener(new adapterview.onitemclicklistener() {     @override     public void onitemclick(adapterview <? > parent, view view, int position, long id) {         if (-1 == firstclickindex) {             firstclickindex = position;         } else {             final int fstdrawable = adapter.get(firstclickindex);             final int snddrawable = adapter.get(position);              if (fstdrawable == snddrawable) {                 // remove stuff, reset firstclickindex.             } else {                 // reset firstclickindex.             }          }     } });
