How do I 'extract' text from ID?

In my test,

I check the text in the header for each page that I land.

I can match the text to “Sign In” (in R.id.toolbar_text) for example and see if it pass or fail. But, I would like to know if it failed, what is the text that I have in R.id.toolbar_text object.

Is the option getText() available in Espresso Android?

val text = getText(withId(R.id.textViewLastPrice))

Here is an equivalent implementation in Java for getText():

public static String getText(final Matcher<View> matcher) {
        try {
            final String[] stringHolder = {null};
            onView(matcher).perform(new ViewAction() {
                @Override
                public Matcher<View> getConstraints() {
                    return isAssignableFrom(TextView.class);
                }

                @Override
                public String getDescription() {
                    return "get text";
                }

                @Override
                public void perform(UiController uiController, View view) {
                    TextView tv = (TextView) view;
                    stringHolder[0] = tv.getText().toString();
                }
            });
            if (stringHolder[0] == null || stringHolder[0] == "") {
                fail("no text found");
            }
            return stringHolder[0];
        } catch (Exception e) {
            fail("null found");
            return null;
        }

    }

Try this (kotlin example):

val toolbar: ViewInteraction = onView(withId(R.id.toolbar_text))

fun getText(viewInteraction: ViewInteraction): String? {
    val stringHolder = arrayOf<String?>(null)
    viewInteraction.perform(object : ViewAction {
        override fun getConstraints() = isAssignableFrom(TextView::class.java)

        override fun getDescription() = "Get text from View: ${stringHolder[0]}"

        override fun perform(uiController: UiController, view: View) {
            val tv = view as TextView
            stringHolder[0] = tv.text.toString()
        }
    })
    return stringHolder[0]
}

val text = getText(toolbar)
