Android Question Turn off/not send haptic when a particular clv_Click happens

Mark Stuart · Aug 15, 2025

Hi all,

I have a CustomListView loaded with "records"/rows. One particular row I don't want the haptic sound to happen, but another row (person row) is touched, I want the haptic to happen.
The CLV is loaded with "group headers" - particular rows that designate that the following rows are part of that group header. The group header is a Month and Year. The following rows match the month and year. Think of birthdays and the group header being the Month and Year row and the following rows have birthdays in that month and year.

I don't need a haptic to happen when the group header is touched, but only when the user touches on the person row.
For to touch on a row and have a haptic feedback doesn't make sense when the group header row is display only and doesn't have any function.

Is this possible?

Thanx,
Mark Stuart

I've added my logic to your app, and it works; it only accepts clicks on elements. To do this, I had to change the click color to something more visible. You had the alpha set to 0.

B4X:

Sub LoadBirthdayRecords
    clvPersons.Clear
  
    Dim sCurrentMonthYear As String
    Dim data As DataSet
    Dim rs As ResultSet
  
    rs = oSQL.ExecQuery("SELECT * FROM tblData ORDER BY BirthDate DESC")
  
    Do While rs.NextRow
        data.ID = rs.GetInt("ID")
        data.FirstName = rs.GetString("FirstName")
        data.LastName = rs.GetString("LastName")
        data.BirthDate = rs.GetLong("BirthDate")
      
        Dim sTempMonthYear As String = GetMonthYear(data.BirthDate)
        If sTempMonthYear <> sCurrentMonthYear Then
            'we...

I was aware of this issue when using a single customlistview, but the simplest solution is to disable the group panel. This prevents the click event from firing on the row where the group is located.
You need to know which row the groups belong to, for example, by adding a flag or disabling the row panel when loading the data.

Works splendidly! Thank you.
BTW - this line needs to be corrected if you want the app to return to the very top of the CLV:
clvPersons.ScrollToItem(1)

Should be: clvPersons.ScrollToItem(0)
