java - 从SQLite数据库删除项目时出错

Question

我正在尝试从SQLite数据库中删除RecyclerView中的项目，但出现以下错误：

java.lang.IndexOutOfBoundsException: Index: 1, Size: 0
    at java.util.ArrayList.get(ArrayList.java:437)
    at com.reogen.bettarium.Fragments.ListFragment.onSwipe(ListFragment.java:135)
    at com.reogen.bettarium.Helpers.SwipeToDelete.onSwiped(SwipeToDelete.java:30)

但是我不明白怎么了。这两行是：

            public Void onSwipe(RecyclerView.ViewHolder viewHolder, int direction, int position) {
    if (viewHolder instanceof ToDoAdapter.ToDoViewHolder) {
        String name = list.get(viewHolder.getAdapterPosition()).get_title();<-----

和

public void onSwiped(@NonNull RecyclerView.ViewHolder viewHolder, int direction) {

    if (listener != null) {
        listener.onSwipe(viewHolder, direction, viewHolder.getAdapterPosition()); <-----

    }

}

为什么我的应用崩溃了并且没有从数据库中删除项目？
非常感谢

编辑：
我正在尝试使用主要片段中的OnSwipe从recyclerView和数据库中删除项目：

 public Void onSwipe(RecyclerView.ViewHolder viewHolder, int direction, int position) {
    if (viewHolder instanceof ToDoAdapter.ToDoViewHolder) {
        String name = list.get(viewHolder.getAdapterPosition()).get_title();
         int deleteIndex = viewHolder.getAdapterPosition();

        toDoAdapter.removeItem(deleteIndex);

        mDatabase.execSQL("DELETE FROM " + TABLE_TODO + " WHERE " + COLUMN_TODONAME + "=\"" + name + "\";");


        //mDatabase.delete(ToDoDBHandler.ToDoItemDatabase.TABLE_TODO, ToDoDBHandler.ToDoItemDatabase.COLUMN_ID + "=" + position, null);
        toDoAdapter.swapCursor(newCursor());
    }

尝试将String name = list.get(viewHolder.getAdapterPosition()).get_title();更改为String name = list.get(position).get_title();
