英文:
onBindViewHolder repeats the results
问题
我创建了一个显示项目列表并在每个项目旁边有复选框的RecyclerView Adapter。
在适配器内部，我创建了：
interface OnItemCheckListener {
void onItemCheck(DiscoverBooks books);
void onItemUncheck(DiscoverBooks books);
}
@NonNull
private OnItemCheckListener onItemCheckListener;
@Override
public void onBindViewHolder(BorrowViewHolder holder, int position) {
holder.bind(items.get(position), position);
final Discoveritems currentItem = items.get(position);
holder.setOnClickListener( v -> {
holder.Cb_Borrow.setChecked( !holder.Cb_Borrow.isChecked());
if (holder.Cb_Borrow.isChecked()) {
onItemCheckListener.onItemCheck(currentItem);
} else {
onItemCheckListener.onItemUncheck(currentItem);
}
} );
}
我为用户提供了选中复选框并稍后使用这些数据的选项。
然而，我发现例如，如果我点击第一个项目的复选框，它会使每7个项目被选中。
例如，我得到：
- 项目1 - 项目被选中
- 项目2
- 项目3
- 项目4
- 项目5
- 项目6
- 项目7
- 项目8 - 项目被选中
- 项目9
- 项目10
- 项目11
- 项目12
- 项目13
- 项目14
- 项目15 - 项目被选中
任何想法为什么会发生这种情况？
谢谢
英文:
I created a RecyclerView Adapter that shows a list of items and next to each on of them there is a Checkbox.
Inside the adapter I created:
interface OnItemCheckListener {
void onItemCheck(DiscoverBooks books);
void onItemUncheck(DiscoverBooks books);
}
@NonNull
private OnItemCheckListener onItemCheckListener;
@Override
public void onBindViewHolder(BorrowViewHolder holder, int position) {
holder.bind(items.get(position), position);
final Discoveritems currentItem = items.get(position);
holder.setOnClickListener( v -> {
holder.Cb_Borrow.setChecked( !holder.Cb_Borrow.isChecked());
if (holder.Cb_Borrow.isChecked()) {
onItemCheckListener.onItemCheck(currentItem);
} else {
onItemCheckListener.onItemUncheck(currentItem);
}
} );
}
Where I give the option for the user to check the Checkbox and to use this data later.
However, I found that if for example, I clicked the Checkbox of the first item, it makes every 7 item to be checked.
For example what I get:
item 1 - item checked
item 2
item 3
item 4
item 5
item 6
item 7
item 8 - item checked
item 9
item 10
item 11
item 12
item 13
item 14
item 15 - item checked
Any idea why it happens?
