Android – delete items from recyclerview

I have a problem deleting items from the list in recyclerview. I want to do the following functions. When I press the check box in the recyclerview list, I want to delete this item from the list. When I press some top / bottom check boxes, this is basically valid, but when I press some of them, I have other check boxes marked as checked, I didn't even touch them. I don't know where the problem comes from

This is the code in my adapter:

public class Shoppinglistadapter extends RecyclerView.Adapter<Shoppinglistadapter.ShoppingListViewHolder> {
private ArrayList<Item> mItems;
private Context mContext;

public Shoppinglistadapter(Context context, ArrayList<Item> items) {
    mItems = items;
    mContext = context;
}

@Override
public ShoppingListViewHolder onCreateViewHolder(ViewGroup viewGroup, int position) {
    View view = LayoutInflater.from(mContext).inflate(R.layout.shopping_list_item,viewGroup,false);
    ShoppingListViewHolder viewHolder = new ShoppingListViewHolder(view);

    return viewHolder;
}

@Override
public void onBindViewHolder(ShoppingListViewHolder shoppingListViewHolder, int position) {
    shoppingListViewHolder.bindShoppingList(mItems.get(position));
}

@Override
public int getItemCount() {
    return mItems.size();
}

public class ShoppingListViewHolder extends RecyclerView.ViewHolder implements CompoundButton.OnCheckedchangelistener{
    public TextView mShoppingListItem;
    public Check@R_487_2419@ mCheck@R_487_2419@;

    public ShoppingListViewHolder(View itemView) {
        super(itemView);
        mShoppingListItem = (TextView) itemView.findViewById(R.id.shoppingListItem);
        mCheck@R_487_2419@ = (Check@R_487_2419@) itemView.findViewById(R.id.shoppingListCheck@R_487_2419@);
        mCheck@R_487_2419@.setOnCheckedchangelistener(this);
    }

    public void bindShoppingList(Item item){
        mShoppingListItem.setText(item.getItemDescription());
    }


    @Override
    public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
        removeAt(getAdapterPosition(),this);
    }
}

public void removeAt(int position,ShoppingListViewHolder viewHolder) {
    mItems.remove(position);
    notifyItemRemoved(position);
}

This is my code in mainactivity:

public class MainActivity extends AppCompatActivity {
private Toolbar mToolbar;
private RecyclerView mRecyclerView;
private ArrayList<Item> shoppingListItems;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    mToolbar = (Toolbar)findViewById(R.id.tool_bar);
    setSupportActionBar(mToolbar);
    mRecyclerView = (RecyclerView)findViewById(R.id.recyclerView);
    shoppingListItems = new ArrayList<>();
    shoppingListItems.add(new Item("Apples"));
    shoppingListItems.add(new Item("Bred"));
    shoppingListItems.add(new Item("Potatoes"));
    shoppingListItems.add(new Item("Muffins"));
    shoppingListItems.add(new Item("Crackers"));
    shoppingListItems.add(new Item("Spaghetti"));
    shoppingListItems.add(new Item("Plastic Bags"));
    shoppingListItems.add(new Item("Deodorant"));
    shoppingListItems.add(new Item("Razors"));
    shoppingListItems.add(new Item("Shampoo"));
    shoppingListItems.add(new Item("Tooth brushes"));
    shoppingListItems.add(new Item("Butter"));
    shoppingListItems.add(new Item("Bagels"));
    shoppingListItems.add(new Item("Coconut water"));
    shoppingListItems.add(new Item("Tomatoes"));

    Shoppinglistadapter adapter = new Shoppinglistadapter(this,shoppingListItems);
    mRecyclerView.addItemDecoration(new SimpleDividerItemDecoration(getApplicationContext()));
    mRecyclerView.setAdapter(adapter);
    mRecyclerView.setLayoutManager(new linearlayoutmanager(this));

}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.menu_main, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();

    //noinspection SimplifiableIfStatement
    if (id == R.id.action_settings) {
        return true;
    }

    return super.onOptionsItemSelected(item);
}

resolvent:

I think "automatic" check items reuse the view holder of deleted items (including the selected check box). When you bind viewholder attempts to (RE) set the check box 'state to false:

ShoppingListViewHolder {
    public void bindShoppingList(Item item){
        mShoppingListItem.setText(item.getItemDescription());
        mCheck@R_487_2419@.setChecked(false);// <- this
    }
}

Onbindviewholder is where you set the project view to match the project data
