        {
            if (thumbIndex == 0) {
                doSmth(String.valueOf(value));
            } else {
                doSmthElse(String.valueOf(value));

Espresso

        onView(ViewMatchers.withId(R.id.multiSlider3))
                .perform(moveThumbForward(0));
    }
    onView(ViewMatchers.withId(R.id.multiSlider3))
            .perform(setThumbValue(0, 50));
    for (int i = 0; i < 15; i++) {
        onView(ViewMatchers.withId(R.id.multiSlider3))
                .perform(moveThumbBackward(0));
    }

UiAutomator

            .getChild(new UiSelector().textStartsWith("thumb 0:")));

    for (int i = 0; i < 15; i++) {
        slider.moveThumbForward();
