Android Question Why Map Overwrite the First Value?

[Pravee7094]

Hi all,
I have a one table. In this table there is one field called "Barcode". I just add two barcodes Named as (S1234, S7890) in the table.
Now I want to read all the data from table and store to database.
Here is the sample coding.

    Dim ll_list As List
    ll_list.Initialize
    Dim lm_map As Map
    lm_map.Initialize
    
    For i = 0 To if_flexgrid_table.RowCount - 1
        Dim RowData As List = if_flexgrid_table.GetCellRow(i)
        
        lm_map.Put("barcode_detail", RowData.Get(0))

        ll_list.Add(lm_map)
    Next
    
    Log("Result : " & ll_list)

Result:

Result : (ArrayList) [{barcode_detail=S7890}, {barcode_detail=S7890}]

I just Want two data one by one. Here, Second barcode overwrite the first barcode.
How can I get two barcodes one by one?

Expected Result:

Result : (ArrayList) [{barcode_detail=S1234}, {barcode_detail=S7890}]

Any suggestions or Help?

Thanks

Move

Dim lm_map As Map
lm_map.Initialize

inside the loop

Wouldn't it be enough to move this into the loop?

lm_map.Initialize

Move

Dim lm_map As Map
lm_map.Initialize

inside the loop

Its cool. Solved. Thanks

No. It would fail to create a new map. It would only initialize the existing map

Oh, right. Thx

Another one:

1. If you put the same key (with a value) to a map, the existing one is overwritten
2. If you use maps containing only one key/value pair it's better to use a simple array or a list
