Android Question [SOLVED] ArrayList, JavaObject and datas extraction

[sirjo66]

Hello to all
in an event I receive two objects, here is the code:

Sub acs_OnAccessibilityEvent (Event As Object, node As Object)

Now I need to extract datas from "node" object, but node object is an ArrayList java object, so:

Dim Jo As JavaObject = node
Dim size As Int = Jo.RunMethod("size", Array As Object())
           
If size > 0 Then ' if there is objects
    Jo = Jo.RunMethod("get", Array As Object(0)) ' extract first object on the list (that is another ArrayList)
    size = Jo.RunMethod("size", Array As Object()) ' size of the ArrayList
    Log("Size = " & size) ' until here is correct !!
               
    For x = 0 To size - 1
        Dim Jo2 As JavaObject = Jo.RunMethod("get", Array As Object(x)) ' extract object number x
        ' now I need to extract (for example) "mClassName" property of this object, but
        ' I don't know how to do it
        ' I try two line below (one at time), but error on each of it
        Dim ViewId As String =  Jo2.GetField("mClassName") '  <<<<<<<< this line error
        Dim ViewId As String =  Jo2.RunMethod("mClassName", Array As Object()) ' <<<<< if I try this, error
    Next
End If

How can extract property from an JavaObject ??

Thanks !!!

You don't need to write 'As Object'. 'Array' is enough.

If node is an ArrayList then you can access it like this:

Dim list As List = node
