Activity destroyed using Fragment

Question

I have a ListView in ListView.class, when the User clicks on one item (let's say item at position =0) Fragment6 should be opened.

Additionally, I have a HandleListClick.class that gets the position ( e.g. position = 0) and then uses a switch to open a fragment, but I get an error.

java.lang.IllegalStateException: Activity has been destroyed

How can I handle this annoying problem? My activity is declared in Manifest.

Here is my ListView.class

  listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {

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

            // ListView Clicked item index
            int itemPosition     = position;

            // ListView Clicked item value
            String  itemValue    = (String) listView.getItemAtPosition(position);


                if (position==0){
                    HandleListClick handleListClick = new HandleListClick();
                    handleListClick.getItemPosition(0);
                }
}

Here is my handleListClick.class

public class HandleListClick extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_handle_list_click);
}


public void getItemPosition(int position) {
    switch (position) {
        case 0:
            Fragment6 frag6 = null;
            frag6 = new Fragment6();
            FragmentManager fragmentManager = getSupportFragmentManager();
            fragmentManager.beginTransaction()
                    .replace(R.id.framelayout, frag6)
                    .commit();


    }
}

}

Here is my Fragment6.java

public class Fragment6 extends Fragment {

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {

   View v = inflater.inflate(R.layout.fragmentdescrip6, container,false);
    return v;



 //  ViewGroup rootView = (ViewGroup) inflater.inflate(
  //         R.layout.fragmentdescrip6, container, false);

 //  return rootView;
}

}

Here is activity_handle_list_click.xml

     <?xml version="1.0" encoding="utf-8"?>
      <android.support.constraint.ConstraintLayout 
      xmlns:android="http://schemas.android.com/apk/res/android"

        android:id= "@+id/framelayout"
        >


    </FrameLayout>

</android.support.constraint.ConstraintLayout>

And here is fragmentdescrip6.xml

 <?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"

        android:layout_height="wrap_content"

        android:textStyle="bold"
        android:textColor="#FFFF4444"
        android:textSize="20dp"
        android:layout_marginTop="17dp"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true" />

    <TextView
        android:id="@+id/textfrag6"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"

        android:layout_alignParentStart="true"
        android:layout_below="@+id/textfrag6label"
        android:layout_marginLeft="16dp"
        android:layout_marginStart="16dp"
        android:layout_marginTop="33dp"
        android:textStyle="bold"
        android:text="some Text" />


</RelativeLayout>

Try it this way

 listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {

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

                // ListView Clicked item index
                int itemPosition     = position;

                // ListView Clicked item value
                String  itemValue    = (String) listView.getItemAtPosition(position);


                if (position==0){
                    Intent intent = new Intent(CurrentActivity.this, HandleListClick.class);
                    intent.putExtra("POSITION", position);
                    startActivity(intent);
                }
                   /* HandleListClick handleListClick = new HandleListClick();
                    handleListClick.getItemPosition(0);*/
                }
            }

Change the Activity code

    public class HandleListClick extends AppCompatActivity {

        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_handle_list_click);
            Intent intent = getIntent();
            int pos = intent.getIntExtra("POSITION",0);
            getItemPosition(pos);
        }


        public void getItemPosition(int position) {
            switch (position) {
                case 0:
                    Fragment6 frag6 = null;
                    frag6 = new Fragment6();
                    FragmentManager fragmentManager = getSupportFragmentManager();
                    fragmentManager.beginTransaction()
                            .replace(R.id.framelayout, frag6)
                            .commit();


            }
        }
    }
