java.lang.IndexOutOfBoundsException : Invalid index

Question

我有一个数组列表，并使用 ImageButton 从列表中删除项目。如果我从同一位置删除 3 个项目，应用程序将崩溃并出现 IndexOutOfBoundsException。我不知道如何在删除项目之前的项目后更改项目的数组位置。

 @Override
public void onBindViewHolder(MyViewHolder holder, final int position) {
    ExRow expense = expenseList.get(position);
    holder.title.setText(expense.getTitle());
    holder.amount.setText(expense.getAmount());
    mRemoveButton.setOnClickListener(new View.OnClickListener() {

        public void onClick(View view) {
            // Remove the item on remove/button click
            expenseList.remove(position);
            notifyItemRemoved(position);
            notifyItemRangeChanged(position, expenseList.size());

        }
    });
}

对此有许多可能的解决方案。

这对我来说是理想的

@Override
public void onBindViewHolder(final MyViewHolder holder, int position) {
    ExRow expense = expenseList.get(holder.getAdapterPosition());
    holder.title.setText(expense.getTitle());
    holder.amount.setText(expense.getAmount());
    mRemoveButton.setOnClickListener(new View.OnClickListener() {
        public void onClick(View view) {
            // Remove the item on remove/button click
            int adapterPosition = holder.getAdapterPosition();
            expenseList.remove(adapterPosition);
            notifyItemRemoved(adapterPosition);
            notifyDatasetChanged();
        }
    });
}
