will help you I have created a list box and at the moment I am trying to make it such that you can delete one item or multiple items using this code: , First, make sure there are some things selected:
code :
If lstCountries.SelectedItems.Count > 0 Then

    ' MUST loop backwards thru collections when removing
    ' or you will remove the wrong things, miss stuff and
    ' run out early
    For n As Integer = lstCountries.SelectedItems.Count - 1 To 0 Step -1
        ' remove the current selected item from items
        lstCountries.Items.Remove(lstCountries.SelectedItems(n))
    Next n
End if

it fixes the issue I am using a RecyclerView for a list. Each layout item of the RecyclerView has a Button. This button is supposed to save some data(that which I bound to the view). , The best way to handle RecyclerView clicks is like this:
code :
@Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    View view = layoutInflater.inflate(R.layout.list_item, parent, false);
    final ViewHolder viewHolder = new ViewHolder(view);

    viewHolder.actionButton.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            int itemPosition = viewHolder.getAdapterPosition();
            handleActionButtonClick(itemPosition);
        }
    });

    return viewHolder;
}

seems to work fine I want to list players and their bets in a roulette game. When the number of
  • tags in the
      is different, the position of the element change: , Add vertical-align:top on r-players
      code :
      .r-players{
          margin:0px;
          margin-top:0px;
          position:relative;
          border:1px solid black;
          vertical-align:top;/*Add this */
          display:inline-block;
          width:calc((100% / 3) - 5px);
          height:calc(100%);
      }

    help you fix your problem str.split(separator, maxsplit) method returns a list of strings after breaking the given string by the specified separator.
    separator: The is a delimiter. The string splits at this specified separator. It is not provided then any white space is a separator.
    code :
    x='ABCDEFG'
    char_list=list(x)
    #['A', 'B', 'C', 'D', 'E', 'F', 'G']
    
    x='abcde fgh   i'
    out=[char for string in x.split() for char in string]
    #['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i']
