how to fill the activity after listview using data from database that works properly

this is how i catch data from database

   private void populateFromDatabaselst() {
        applications.clear();
        Cursor cursor = G.database.rawQuery("SELECT * FROM app  group by app_phoneNumber", null);
        while (cursor.moveToNext()) {
            structapplication application = new structapplication();
            application.name = cursor.getString(cursor.getColumnIndex("app_name"));

            application.text = cursor.getString(cursor.getColumnIndex("app_text"));
            application.page = cursor.getInt(cursor.getColumnIndex("app_page"));

            application.season = cursor.getString(cursor.getColumnIndex("app_season"));
            application.star = cursor.getInt(cursor.getColumnIndex("app_star"));

            applications.add(application);
        }
        cursor.close();

        adapter.notifyDataSetChanged();

then i use name and season to fill the items in listview

  public void fill(final ArrayAdapter<structapplication> adapter, final structapplication item, final int position) {
            txttitle.setText(item.name);
            txtdescription.setText(item.season);

            layoutRoot.setOnClickListener(new OnClickListener() {

                @Override
                public void onClick(View arg0) {
                    G.selectedApplication = item;

                    Intent intent = new Intent(G.currentActivity, matnasli.class);
                    G.currentActivity.startActivity(intent);
                }
            });
        }
    }    

i grouped data in listview with this code ("SELECT * FROM app group by app_phoneNumber") but in the activity after listview is where my problems begin i cant use this code in the next activity it doesnt work properly

txtAuthor.setText(G.selectedApplication.season);
txtname.setText(G.selectedApplication.name);
txtDescription.setText(G.selectedApplication.text);

i mean for ex when u click in first item in listview i need it to show u the first coloum in the db but it shows some other column that i cant control, i need each group of datas to show its first field in the database and after that i can use a button to go to its next field in database.
