Espresso - get text of element

If I have an "AppCompatTextView" element that I can access by:

onView(withId(R.id.allergies_text))

From Layout Inspector:

enter image description here

Is there a way I can access the text of the element in Android Studio? (to access whatever text is there... not check if some text exists in the element)

I tried to do:

val tv = onView(withId(R.id.medical_summary_text_view)) as TextView
val text = text.text.toString()
print(text)

But I get the error:

android.support.test.espresso.ViewInteraction cannot be cast to android.widget.TextView

You can get the text of the ViewInteraction by the following function:

fun getText(matcher: ViewInteraction): String {
    var text = String()
    matcher.perform(object : ViewAction {
        override fun getConstraints(): Matcher<View> {
            return isAssignableFrom(TextView::class.java)
        }

        override fun getDescription(): String {
            return "Text of the view"
        }

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

    return text
}

val numberResult: ViewInteraction = onView(withId(R.id.txNumberResult))
var searchText = getText(numberResult)

I faced a similar issue and this is what ended up working for me:

if you have an activity rule 

var activityRule = ActivityTestRule(MainActivity::class.java, true, false)

then you can do something like this: 

activityRule.launchActivity(null)
val textView: TextView = activityRule.activity.findViewById(R.id.some_text_view)
val text = textView.text

I think this may be more along the lines of what the original poster was looking for.

When you really want to have the text and not only match it with another value or empty, I post the full final working solution in Java (Not Kotlin) based on the algoritghm of @Mesut GUNES

public class TextHelpers {
public static String getText(ViewInteraction matcher){
    final String[] text = new String[1];
    ViewAction va = new ViewAction() {

        @Override
        public Matcher<View> getConstraints() {
            return isAssignableFrom(TextView.class);
        }

        @Override
        public String getDescription(){
            return "Text of the view";
        }

        @Override
        public void perform(UiController uiController,View view) {
            TextView tv = (TextView) view;
            text[0] = tv.getText().toString();
        }
    };

    matcher.perform(va);

    return text[0];
}

}

So, in your test you can call it like that:

TextHelpers.getText(Espresso.onView(withId(R.id.element)));

It works for all controls extending TextView, so it does on EditText too.
