Android Question AutoCompleteEditText with INPUT_TYPE_DECIMAL_NUMBERS

[peacemaker]

HI, All

Anyone tried to use the AutoCompleteEditText view with the list of decimal values ?
Say, 0.5, 1, 1.5, 2, 2.5 ......
So the aim is to fastly choose from list or enter (say 3.35) manually.
How to show the filtered suggestion list ? Rebuild the list every TextChanged ?

If to do so:

Sub txtQty_TextChanged (Old As String, New As String)
    Dim L As List
    L.Initialize
    Dim j As Float
    For j = 0.5 To 10 Step 0.5
        Dim a As String = j
        If a.Contains(New) Then
            L.Add(a)
        End If
    Next
    If L.Size > 0 Then
        txtQty.SetItems(L)
        txtQty.ShowDropDown
    End If
End Sub

there is a error after ItemClick:

** Activity (neworder) Resume **

Note that SearchView is not enough - the manual input result is also needed.
Also note that suggest list cannot hold Float values, just compatible with CharSequence types...

Changing the items in the TextChanged event probably breaks it.

Note that SearchView is not enough - the manual input result is also needed.

SearchView doesn't force the user to select an item.

Yes.
I have added

Sub getText As String
    Return et.Text
End Sub

But found a new trouble that the SearchView cannot just be placed at the activity bottom, like narrow (AutoComplete)EditText.
