Android Question Errors when using ForEach... Next on Views

[markm]

Hi, so far, really liking B4A and find it very familiar and easy to use. However, I'm running into an issue I've searched for and have not found an answer for.
I get the error "java.lang.ClassCastException: android.widget.TextView cannot be cast to android.widget.EditText" when trying to run the following code:

For Each et as EditText in Activity
       et.text = ""
Next

or

For Each et as EditText in Activity
       If isnumber(et.text) then
             <code>
       End If
Next

I wrapped with an if/then which makes it run correctly other times, but at least 50% of the time, it still gives the above error:

For Each et as EditText in Activity
        If et is EditText then
                  et.text = ""
        End If
Next

I only need to test against EditText views, and if I try:

For Each et as View in Activity
       If et is EditText Then
                et.text = ""
       End If
Next

then I get an error "Unknown Member: Text"

For now, there are only 8 EditText views on the activity, so I just set up a sub to set them to blank, but I have a couple of Activities lined up that will have several EditText views and I'll need an easy way to batch work with the text in them.

Give this a try...

    For Each v As View In Activity.GetAllViewsRecursive
        If v Is EditText Then
            Dim et As EditText = v
            et.Text = ""
        End If
Next

Thanks, I'll try it when I get a chance.
