Using TapTargetView on Navigation Drawer menu item

Question

I'm using TapTargetView to create my Showcase and it's working nice to buttons and the toolbar, but I need to target my Navigation Drawer menu and I'm not getting there.

One of my aproaches was to create a local variable TextView (or anything else) and use app:actionViewClass on my menu item. The target is reached but not like expected, because the actionViewClass is on the right margin of the menu item look the screenshot

<item
    android:id="@+id/nav_criar_projeto"
    android:icon="@drawable/ic_add"
    android:title="@string/criar_projeto"
    app:showAsAction="always"
    app:actionViewClass="android.widget.TextView" />

TapTarget.forView(
  navigationView.getMenu().findItem(R.id.nav_criar_projeto).getActionView(),
     "Vamos criar nosso primeiro projeto",
     "Você ainda não possui um projeto, vamos criar um")

Is it possible to target the icon or the text of this menu item?

I'm not familiar with how `TapTargetView` works, exactly, but one way to get that menu item's main `View` is to set an `app:contentDescription` on the ``, then call `findViewsWithText(outList, desc, View.FIND_VIEWS_WITH_CONTENT_DESCRIPTION)` on the `NavigationView` to get an `ArrayList` of `View`s with that description. If it's unique in the `NavigationView`, you should be good; i.e., it should be `outList`'s only element. — Mike M., Aug 21 '19 at 13:56
Thanks Mike, but it seams not to work for one reason: my NavigationView is modifyed at runtime, and the menu I need is one of this that is inflated. When I search for one of the pre existing item, the result contains 1 view, but its null for the one I need. Maybe I need to execute on a listener after the menu is fully loaded — Renan Ceratto, Aug 21 '19 at 14:46
Oh, there's `View.FIND_VIEWS_WITH_TEXT`, too, that you can use with the title. Sorry, I'm just so used to doing the content description trick, when multiple `View`s have the same text. — Mike M., Aug 21 '19 at 14:53
Worked! But just after calling the method using `new Handler().post()` — Renan Ceratto, Aug 21 '19 at 15:12
Oh, is that what you meant about the listener for after loading? Yeah, you'd have to give it a chance to add and layout. Cool. Glad you got it working. Cheers! — Mike M., Aug 21 '19 at 15:15
Oh, I'm good. :-) Please feel free to post an answer with your final setup. This will be a good link in the future for others with the same question. Thank you, though. I appreciate the offer. Cheers! — Mike M., Aug 21 '19 at 16:29

Solved this by setting app:contentDescription="name_here" to my <item> inside the <menu> Then just call

navigationView.findViewsWithText(menuItems, "name_here", View.FIND_VIEWS_WITH_CONTENT_DESCRIPTION);

But to work properly, the code above need to be called on a new thread, so the interface have enough time to render.

new Handler().post(new Runnable() {
                    @Override
                    public void run() {
                        methodToFindTheView();
                    }
                });
