Trying to get the _id when an item in gridview is clicked getting a cast exception

Question

I am trying to get the _id field from the cursor when an item in my Grid View is clicked, the same code is working fine in a listview but does not seem to work here:

Class level:

CurAdapter Cur;
GridView grid;

onCreate:

Cursor mCur = dbHelper.contactsQuery(); 
grid = (GridView)rootView.findViewById(R.id.gridview); 
Cur = new CurAdapter(getActivity(), mCur,0); 
grid.setAdapter(Cur);
grid.setTextFilterEnabled(true);

onCLick:

grid.setOnItemClickListener(new OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view,int position, long id) {

                System.out.println(position);
                System.out.println(id);

                Cursor cursor = (Cursor) grid.getItemAtPosition(position);

            }
        }); 

My CustomAdapter:

private class CurAdapter extends CursorAdapter{

        public CurAdapter(Context context, Cursor c, int flags) {

            super(context, c, flags);

        }



        @Override
        public void bindView(View view, Context context, Cursor cursor) {

            TextView tv = (TextView) view.findViewById(R.id.item_text);
            tv.setTypeface(helv_light); 
            final RoundedImageView iv = (RoundedImageView) view.findViewById(R.id.item_image);

            String name = (cursor.getString(cursor.getColumnIndexOrThrow("Name")));
            image = cursor.getString(cursor.getColumnIndexOrThrow("imageUri"));
            String isAdhoc = (cursor.getString(cursor.getColumnIndexOrThrow("isAdhoc")));

            if(isAdhoc.equals("1")){
                boolean check = false; 
                String frName = null;
                Cursor mCur = dbHelper.friendsName(name);
                if(mCur != null && mCur.moveToFirst()){
                    do{
                        frName = mCur.getString(mCur.getColumnIndex("FriendsName")); 
                        if(frName != null){


                            if(frName.equalsIgnoreCase(selfName)){
                                check = false; 
                            }else {

                                check = true; 


                            }  


                        }

                    }while (mCur.moveToNext()); 
                }

                if(check){
                    name = name+" "+"("+frName+"'s"+" pet)"; 
                }

            }


            tv.setText(name);


            if((image.contains("jpg") || image.contains("png")) && image.contains("adhoc") != true){

                image = "file://"+image; 

            }

            final DisplayImageOptions options = new DisplayImageOptions.Builder()
            .showImageOnLoading(R.drawable.icon_default)
            .showImageForEmptyUri(R.drawable.icon_default)
            .showImageOnFail(R.drawable.icon_default) 
            .resetViewBeforeLoading(true)  
            .cacheInMemory(true) // default
            .cacheOnDisk(true) // default
            .build();

            ImageLoader.getInstance().displayImage(image, iv, options); 

        } 
        @Override
        public View newView(Context context, Cursor cursor, ViewGroup parent) {

            View view = LayoutInflater.from(context).inflate(R.layout.grid_layout, null);

            return view;

        }


        public long getItemId(int position) { 

            return position;  
        }  

        public Object getItem(int position) {
            return position;
        }

    }

My Problem:

11-10 14:51:47.989: E/AndroidRuntime(11194): java.lang.ClassCastException: java.lang.Integer cannot be cast to android.database.Cursor
11-10 14:51:47.989: E/AndroidRuntime(11194):    at com.example.FragmentTab3$1.onItemClick(FragmentTab3.java:125)

Answer 1

you are getting the ClassCastException because you are overriding getItem

 public Object getItem(int position) {
        return position;
 }

and in your case it is returning an int not the cursor. You can delete it and use the parent implementation of getItem (which should return the Cursor at position)

Answer 2

Exception is due to return int from getItem(..) as mentioned by blackbelt

This may also help you to get ID of the record - change getItemId(..) this way:

public long getItemId(int position) { 
            mCur.moveToPosition(position);
            return mCur.getLong(mCur.getColumnIndex(BaseColumns._ID));  
        }
