get clicked item of gridview to access it from getView in Adapter

[Kevin Rapter]

I just created a city object with other essential things like tourist places. I used arraylist in the Arraylist .

There is any object in the arrayslist .Here is the code below.

City city = new City();

       city.setCityName("London");
       city.setmCityImageResourceId(R.drawable.london);

       AttactivePlaces londonAttactivePlaces_one =new AttactivePlaces();
       londonAttactivePlaces_one.setPlaceName("Big Ben");
       londonAttactivePlaces_one.setmAttaticePlaceImageResourceId(R.drawable.bigben);
       londonAttactivePlaces_one.setPlaceDetailInformation("Big Ben");
       city.getAttactivePlaces().add(londonAttactivePlaces_one);


MainActicity

CityAdapter cityAdapter = new CityAdapter(this,cityArraylist,R.color.mainBackground);

       GridView gridView = (GridView) findViewById(R.id.gridlist);
       gridView.setAdapter(cityAdapter);

       gridView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
           @Override
           public void onItemClick(AdapterView<?> adapterView, View view, int position, long l) {

               switch (position){

                   case 0:
                       //Toast.makeText(getApplicationContext(),"İstanbul",Toast.LENGTH_SHORT).show();
                       Toast.makeText(getApplicationContext(),position+"",Toast.LENGTH_SHORT).show();
                       Intent intent = new Intent(MainActivity.this,AttactivePlacesActivity.class);
                       intent.putExtra("position_griditem_one",position);
                       startActivity(intent);
                       break;

AttractivePalcesActivity

ArrayList<City> cityAttactivePlaces = new ArrayList<City>();

     
       cityAttactivePlaces = MainActivity.cityArraylist;

       AttractivePlacesAdapter attractivePlacesAdapter = new AttractivePlacesAdapter(this,cityAttactivePlaces,R.color.mainBackground);

       ListView listView = (ListView) findViewById(R.id.listviewAttactivePlaces);

       listView.setAdapter(attractivePlacesAdapter);


AttractivePlacesAdapter

public class AttractivePlacesAdapter extends ArrayAdapter<City> {

   private int mBackgroundColor; // BackGround Color For each Activity


   public AttractivePlacesAdapter(Context context, ArrayList<City> resources, int color) {
       // Here, we initialize the ArrayAdapter's internal storage for the context and the list.
       // the second argument is used when the ArrayAdapter is populating a single TextView.
       // Because this is a custom adapter for two TextViews , the adapter is not
       // going to use this second argument, so it can be any value. Here, we used 0.
       // 0 -> list item layout resource ID
       super(context,0 ,resources);
       mBackgroundColor = color;
   }


   // get list item from getView

   /**
    * Provides a view for an AdapterView (ListView, GridView, etc.)
    *
    * @param position The position in the list of data that should be displayed in the
    *                 list item view.
    * @param convertView The recycled view to populate.
    * @param parent The parent ViewGroup that is used for inflation.
    * @return The View for the position in the AdapterView.
    */
   @Override
   public View getView(int position, View convertView, ViewGroup parent) {

       // Check if the existing view is being reused, otherwise inflate the view
       View listview = convertView;
       if (listview == null) {
           // parent -> listView   false -> we don't want to attach list item to parent
           listview = LayoutInflater.from(getContext()).inflate(R.layout.layout, parent, false);
       }

       // get position of item to city
       //City city = getItem(position);

       ArrayList<City> cityArrayList = MainActivity.cityArraylist;

       City city = cityArrayList.get(1);

       for(int i=0;i<city.getAttactivePlaces().size();i++){

           // City Information
           TextView name = (TextView) listview.findViewById(R.id.bilgi_text_view);
           name.setText(city.getAttactivePlaces().get(i).getPlaceName());


           // Picture of City
           ImageView image = (ImageView) listview.findViewById(R.id.image_image_view);

           // Check whether the picture is or not.
           if (city.hasImage()) {
               //
               image.setImageResource(city.getAttactivePlaces().get(i).getmAttaticePlaceImageResourceId());
           } else {
               image.setVisibility(View.GONE);
           }

       }

       // City Information
       //TextView name = (TextView) listview.findViewById(R.id.name);

       //name.setText(city.getAttactivePlaces().get(0).getPlaceName());

       //city.getAttactivePlaces().get(position).getPlaceName()

       // Picture of City
       //ImageView image = (ImageView) listview.findViewById(R.id.image_image_view);

       // Check whether the picture is or not.
       //if (city.hasImage()) {
           //
       //    image.setImageResource(city.getAttactivePlaces().get(0).getmAttaticePlaceImageResourceId());
       //} else {
       //   image.setVisibility(View.GONE);
       //}


       // Set theme color for the list item
       View textContainer = listview.findViewById(R.id.text_container);

       // Find the color that the resource ID maps to
       int color = ContextCompat.getColor(getContext(), mBackgroundColor);

       // Set Background color to view
       textContainer.setBackgroundColor(color);

       return listview;

   }

}

When I clicked any item of gridview, list informaiton of this item.  I ask it to many platform but not required response is occured.

How do I access clicked item' position  of gridview form AttractivePlacesAdapter.

I will apprecate you if you answer my quesiton and show the solution step by step.

This looks like an Android question. Moving to a more appropriate forum.
