How does Expresso generate View Hierarchy when performing actions?

[pezh...@gmail.com]

Hi,

I'd like to dynamically decide what views to click. So I did this 

View decor = getActivity().getWindows().getView()

ArrayList<View> views = new ArrayList<>();
for (View v : TreeIterables.breadthFirstViewTraversal(decor)) {
    views.add(v);
}

But after I printed out the views array, it is actually a different view hierarchy as Espresso generates.

This is especially true when a dialog pops up, Espresso will be able to find the correct view hierarchy however my way fails.

Any idea?

Could you guys elaborate a bit on what you're trying to do and what you're asking? I, for one, am not clear on what you're getting at here. Like "I'd like to dynamically decide what views to click." What does that mean and why do you need this?

When espresso cannot find a matching view, it generates this kind of errors:

Espresso no matching view exception: android.support.test.espresso.NoMatchingViewException: No views in hierarchy found matching: with content description: is "Highscore, Open navigation drawer"

                                                                             If the target view is not part of the view hierarchy, you may need to use Espresso.onData to load it from one of the following AdapterViews:com.android.internal.view.menu.ExpandedMenuView{3450462 VFED.VC.. .F...... 12,12-387,84 #102032a android:id/expanded_menu}

                                                                             

                                                                             View Hierarchy:

                                                                             +>DecorView{id=-1, visibility=VISIBLE, width=399, height=84, has-focus=true, has-focusable=true, has-window-focus=true, is-clickable=false, is-enabled=true, is-focused=false, is-focusable=false, is-layout-requested=false, is-selected=false, root-is-layout-requested=false, has-input-connection=false, x=0.0, y=0.0, child-count=1} 

                                                                             |

                                                                             +->ExpandedMenuView{id=16909098, res-name=expanded_menu, visibility=VISIBLE, width=375, height=72, has-focus=true, has-focusable=true, has-window-focus=true, is-clickable=true, is-enabled=true, is-focused=true, is-focusable=true, is-layout-requested=false, is-selected=false, root-is-layout-requested=false, has-input-connection=false, x=12.0, y=12.0, child-count=1} 

                                                                             |

I just want to know how to generate the View Hierarchy
