        } catch (Exception ex) {
            ex.printStackTrace();
        }
    }


    public void createListView() {

        listView.setAdapter(customListAdapter);

    }



//ı try this dont work
    public void istyertikla() {

                MyModel clickedItem = customListAdapter.getItemAtPosition(position);

                if (clickedItem != null) {
                    Toast.makeText(IstanbulActivity.this, "Tıklanan öğe: " + clickedItem.getYerIsim(), Toast.LENGTH_SHORT).show();
                }
            }
        });
    }



}

listview xml 看起来像这样

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".IstanbulActivity">

    <ListView
        android:clickable="true"
        android:id="@+id/listShowJSONData"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginStart="20dp"
        android:layout_marginEnd="20dp"
        android:focusable="true" />


</LinearLayout>
