Espresso: Clicking on Recycler view with unknown position

Question

I Have Have a list if recycler views in different positions in screen. Like below

• I want to click on specific recycler view based on the variable text 'Job#' Inside it.
• But cannot perform the same as I do not know the exact position I should click.

• The position of recycler view keeps changing. Tried below code but it clicks on static position '6'

  recyclerView = onView( allOf(withId(R.id.recycler_view), isDisplayed())); recyclerView.perform(actionOnItemAtPosition(6, click()));

I want to know the proper position dynamically.

Answer 1

Clicking the position in instrumentation tests, in my opinion, is a bad practice as it leads to non-deterministic tests. This is applicable to both RecyclerView and AdapterView.

So in order to not rely on a position you need an itemView matcher for your recyclerview action.

ItemView matcher is a view matcher that matches the itemview of the ViewHolder. In your case you need to match a LinearLayout that holds the highlighted RelativeLayout, which can be represented as hasDescendant(withText("Job 109"))

The end solution in your case should look like:

onView(allOf(withId(R.id.recycler_view),isDisplayed())).perform(Recyclerview actions.actionOnItem(hasDescendant(withText("Job 109")), click()));
