Answer 1

I know I am late but it will help to others.

 onData(anything())
                .inAdapterView(withId(listviewID))
                .atPosition(0)
                .onChildView(withId(childViewID))
                .perform(click());

This will help you to click on particular view inside listview with customlayout

Answer 2

try this,

((ImageView)((FrameLayout) listview.getChildAt(position)).getChildAt(position)).performClick();

this may help you
