ArrayAdapter , check if checkbox is checked and remove the row after animation

Question

Hello how can I check if a checkbox is check, and if it is check how can I remove the row in question ? thank you

ArrayAdapter :

public class Todoadapter extends ArrayAdapter<Todo> {


    private Context mcontext;
    int mresource;
    public Todoadapter(@NonNull Context context, int resource, @NonNull List<Todo> objects) {
        super(context, resource, objects);
        this.mresource=resource;
        this.mcontext= context;


    }

    @NonNull
    @Override
    public View getView(int position, @Nullable View convertView, @NonNull ViewGroup parent) {
        String todo = getItem(position).getTodo();

        LayoutInflater inflater = LayoutInflater.from(mcontext);
        convertView = inflater.inflate(mresource,parent,false);
        CheckBox box = (CheckBox)convertView.findViewById(R.id.checkBox2);
        box.setText(todo);

    return convertView;
    }

}

My main activity :

public class MainActivity extends AppCompatActivity {

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

    ListView view = (ListView)findViewById(R.id.listview);

    Todo eat = new Todo("Eat ");
    Todo sleep = new Todo("Sleep");

    ArrayList<Todo> todolist = new ArrayList<>();
    todolist.add(eat);
    todolist.add(sleep);

    Todoadapter adapter = new Todoadapter(this,R.layout.custom_adapter_layout,todolist);
    view.setAdapter(adapter);


}

}

My XML

The problem is the row still visible

This is the approach, I don't know exactly how you are populating your list and if you are using the Recycler View, but this should be the body for what you want.

box.setText(todo); 
box.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if(box.isChecked()){
                    //Delay to see animation
                    Handler handler = new Handler();
                    handler.postDelayed(new Runnable() {
                        @Override
                        public void run() {
                            objects.remove(getItem(position)); //Your object list where you have the itens
                            notifyDataSetChanged(); //If you are using a recycler view.
                        }
                    },300); //adding 0.3 sec delay
                }
            }
        });
return convertView;

EDIT: For get your list, probably you should do something like this:

private List<Todo> objects = new List<>(); //NEW
private Context mcontext;
int mresource;

public Todoadapter(@NonNull Context context, int resource, @NonNull List<Todo> objects) {
    super(context, resource, objects);
    this.mresource=resource;
    this.mcontext= context;
    this.objects = objects //NEW

}
