Android studio 使用AlertDialog后，无法删除LIstView中的选定项目

我的问题是：

在我的应用程序中，我为我的ListView设置了ChoiceMode（CHOICE_MODE_MULTIPLE_MODE）和MultiChoiceModeListener方法，以允许用户使用上下文菜单删除列表中的项目。我已经在onActionItemClicked方法中添加了以下代码，一切正常：

        @Override
        public boolean onPrepareActionMode(ActionMode mode, Menu menu) {
            return false;
        }

    @Override
    public void onDestroyActionMode(ActionMode mode) {
        //Clear the list of selected item's id when the user exit the context menu bar.
        mSelectedItemIdList.clear();
    }

        @Override
        public boolean onActionItemClicked(ActionMode mode, MenuItem item) {
            switch (item.getItemId()){
                case R.id.menu_select_delete:
                    deleteSelectedItem();
                    mode.finish();
                    return true;
                default:
                    return false;
            }
        }

        private void deleteSelectedItem(){
    int totalRowDeleted = 0;

    if (!mSelectedItemIdList.isEmpty()){
        for (int i = 0; i < mSelectedItemIdList.size(); i++){
            long idInDatabase = mSelectedItemIdList.get(i);
            Uri selectedItemUri = ContentUris.withAppendedId(TimeEntry.CONTENT_URI, idInDatabase);
            int rowDeleted = getContentResolver().delete(selectedItemUri, null, null);

            if (rowDeleted != 0){
                totalRowDeleted++;
            }
        }
    }

    if (totalRowDeleted == 0){
        Toast.makeText(MainActivity.this, getString(R.string.delete_error_message), Toast.LENGTH_SHORT).show();
        return;
    }

    Toast.makeText(MainActivity.this, totalRowDeleted + " " + getString(R.string.delete_success_message), Toast.LENGTH_SHORT).show();
}

应用程序没有崩溃，但是deleteSelectedItem（）不再工作了！不知何故，程序无法到达方法内部for循环中的内容。也许我犯了一些简单的错误。有人能帮我吗？

我解决了这个问题

每次显示AlertDialog时都会调用onDestroyActionMode（）方法。因此，我删除了onDestroyActionMode（）中的代码，并添加了删除记录后清除列表的代码

private void deleteSelectedItem(){
int totalRowDeleted = 0;

if (!mSelectedItemIdList.isEmpty()){
    for (int i = 0; i < mSelectedItemIdList.size(); i++){
        long idInDatabase = mSelectedItemIdList.get(i);
        Uri selectedItemUri = ContentUris.withAppendedId(TimeEntry.CONTENT_URI, idInDatabase);
        int rowDeleted = getContentResolver().delete(selectedItemUri, null, null);

        if (rowDeleted != 0){
            totalRowDeleted++;
        }
    }
}

if (totalRowDeleted == 0){
    Toast.makeText(MainActivity.this, getString(R.string.delete_error_message), Toast.LENGTH_SHORT).show();
    return;
}

Toast.makeText(MainActivity.this, totalRowDeleted + " " + getString(R.string.delete_success_message), Toast.LENGTH_SHORT).show();

//Clear the list of selected item's id after delete the records.
mSelectedItemIdList.clear();

private void deleteSelectedItem（）{
int totalRowDeleted=0；
如果（！mSelectedItemIdList.isEmpty（））{
对于（int i=0；i

}

private void deleteSelectedItem(){
int totalRowDeleted = 0;

if (!mSelectedItemIdList.isEmpty()){
    for (int i = 0; i < mSelectedItemIdList.size(); i++){
        long idInDatabase = mSelectedItemIdList.get(i);
        Uri selectedItemUri = ContentUris.withAppendedId(TimeEntry.CONTENT_URI, idInDatabase);
        int rowDeleted = getContentResolver().delete(selectedItemUri, null, null);

        if (rowDeleted != 0){
            totalRowDeleted++;
        }
    }
}

if (totalRowDeleted == 0){
    Toast.makeText(MainActivity.this, getString(R.string.delete_error_message), Toast.LENGTH_SHORT).show();
    return;
}

Toast.makeText(MainActivity.this, totalRowDeleted + " " + getString(R.string.delete_success_message), Toast.LENGTH_SHORT).show();

//Clear the list of selected item's id after delete the records.
mSelectedItemIdList.clear();
