如何 deselect/uncheck select 以编程方式在多 select ListView 中添加项目
How to deselect/uncheck a selected item programatically in multi select ListView
我有一个多 select 票单列表。所以我可以 select 多张票并一次删除它们。但是一些特定的工单不能从列表中删除。所以我不想在单击该项目时使它们 selected/checked 成为多个 select。因此，我尝试在使用 listView.setItemChecked(position, false) 单击它时取消 select 特定票证，但它不起作用。
listView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE_MODAL);
单击项目时调用此方法：
listView.setMultiChoiceModeListener(new MultiChoiceModeListener() {
@Override
public void onItemCheckedStateChanged(ActionMode mode,
int position, long id, boolean checked) {
System.out.println("############### Position : " +position +" id: "+id+ " checked : "+checked );
//Getting the ticket
ticket = ticketList.get(position);
if(ticket.getparticularIds()!= null && !ticket.getparticularIds().isEmpty()) {
//***Do not select this ticket***
Toast.makeText(mContext, "Not Allowed", Toast.LENGTH_SHORT).show();
// De-selecting the particular ticket
listView.setItemChecked(position, false);
mAdapter.notifyDataSetChanged();
// Set the CAB title according to total checked items
mode.setTitle(listView.getCheckedItemCount() + " Selected ");
}
else {
mAdapter.toggleSelection(position);
}
mode.setTitle(listView.getCheckedItemCount() + " Selected ");
}

这就是我所做的一切，但它对我不起作用。我该如何解决？？？
我找到了解决方案以防有人需要知道，问题是再次回调 onItemCheckedStateChanged() 方法因为
listView.setItemChecked(position, false);
它会将该位置选中的项目设置为 false 然后它会再次调用 onItemCheckedStateChanged() 并且这次值为 false。所以它会显示堆栈溢出错误或无限循环调用相同的函数。
所以需要用这个代码替换。
if (listView.isItemChecked(position))
listView.setItemChecked(position, false);
它一定很有魅力。
我有一个多 select 票单列表。所以我可以 select 多张票并一次删除它们。但是一些特定的工单不能从列表中删除。所以我不想在单击该项目时使它们 selected/checked 成为多个 select。因此，我尝试在使用 listView.setItemChecked(position, false) 单击它时取消 select 特定票证，但它不起作用。
listView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE_MODAL);
单击项目时调用此方法：
listView.setMultiChoiceModeListener(new MultiChoiceModeListener() {
@Override
public void onItemCheckedStateChanged(ActionMode mode,
int position, long id, boolean checked) {
System.out.println("############### Position : " +position +" id: "+id+ " checked : "+checked );
//Getting the ticket
ticket = ticketList.get(position);
if(ticket.getparticularIds()!= null && !ticket.getparticularIds().isEmpty()) {
//***Do not select this ticket***
Toast.makeText(mContext, "Not Allowed", Toast.LENGTH_SHORT).show();
// De-selecting the particular ticket
listView.setItemChecked(position, false);
mAdapter.notifyDataSetChanged();
// Set the CAB title according to total checked items
mode.setTitle(listView.getCheckedItemCount() + " Selected ");
}
else {
mAdapter.toggleSelection(position);
}
mode.setTitle(listView.getCheckedItemCount() + " Selected ");
}

这就是我所做的一切，但它对我不起作用。我该如何解决？？？
我找到了解决方案以防有人需要知道，问题是再次回调 onItemCheckedStateChanged() 方法因为
listView.setItemChecked(position, false);
它会将该位置选中的项目设置为 false 然后它会再次调用 onItemCheckedStateChanged() 并且这次值为 false。所以它会显示堆栈溢出错误或无限循环调用相同的函数。 所以需要用这个代码替换。
if (listView.isItemChecked(position))
listView.setItemChecked(position, false);
它一定很有魅力。
