Click on not fully visible imageButton with Espresso

Question

I have a custom ImageButton that is not fully visible, by design, so when I perform a click action I get this error:

android.support.test.espresso.P         


        

Answer 1

None of the above worked for me. Here is a custom matcher that completely removes that constraint and allows you to click on the view

 onView(withId(yourID)).check(matches(allOf( isEnabled(), isClickable()))).perform(
            new ViewAction() {
                @Override
                public Matcher<View> getConstraints() {
                    return ViewMatchers.isEnabled(); // no constraints, they are checked above
                }

                @Override
                public String getDescription() {
                    return "click plus button";
                }

                @Override
                public void perform(UiController uiController, View view) {
                    view.performClick();
                }
            }
    );

Answer 2

This helped me to resolve button visibility while running my tests

public static ViewAction handleConstraints(final ViewAction action, final Matcher<View> constraints)
{
    return new ViewAction()
    {
        @Override
        public Matcher<View> getConstraints()
        {
            return constraints;
        }

        @Override
        public String getDescription()
        {
            return action.getDescription();
        }

        @Override
        public void perform(UiController uiController, View view)
        {
            action.perform(uiController, view);
        }
    };
}

public void clickbutton()
{
    onView(withId(r.id.button)).perform(handleConstraints(click(), isDisplayingAtLeast(65)));
}

Answer 3

You have to scroll to the button before:

onView(withId(R.id.button_id)).perform(scrollTo(), click());

Answer 4

Default click of Espresso is requiring visibility of view > 90%. What do you think about creating an own click ViewAction? Like this...

public final class MyViewActions {
   public static ViewAction click() {
      return new GeneralClickAction(SafeTap.SINGLE, GeneralLocation.CENTER, Press.FINGER);
    }
}

This click will click on the center of your view.

Then you could execute click like this: onView(withId(....)).perform(MyViewActions.click());

I hope it could work.

Answer 5

Create your own ViewAction class without view visibility constraints:

 public static ViewAction myClick() {

    return new ViewAction() {
        @Override
        public Matcher<View> getConstraints() {
            return ViewMatchers.isEnabled(); // no constraints, they are checked above
        }

        @Override
        public String getDescription() {
            return null;
        }

        @Override
        public void perform(UiController uiController, View view) {
            view.performClick();
        }
    };

}

Then to use it:

onView(withId(R.id.your_view_id)).perform(myClick());

Answer 6

I don't think there is any easy, elegant solution to this. The 90% constraint is hardcoded in GeneralClickAction, and the class is final so we can't override getConstraints.

I would write your own ViewAction based on GeneralClickAction's code, skipping the isDisplayingAtLeast check.
