can any one tell me how to simulate touch on Image Button using android view client python
The simplest way is using culebra:
$ culebra -VC -o myscript.py
Then, edit myscript.py
and search for your ImageView, it might be something like
# class=android.widget.ImageView
no_id20 = vc.findViewByIdOrRaise("id/no_id/20")
and add
no_id20.touch()
save the edited script and run it.
$ ./myscript.py
