Espresso custom Matcher get child TextView content

I am working on writing a custom Espresso Matcher, but inside

protected boolean matchesSafely(View item)

how to correctly get the child views?

In my case, I want to find the child TextView with id class_name and store its String content to

private String className;

and then try to print this information inside

public void describeTo(Description description)

to get an informative result.

I have tried item.findViewById() and getChildAt(0), but both do not work.

Kindly please help me with this, thanks a lot!

My list_item.xml is as below:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <RelativeLayout
        android:id="@+id/section_header_class_name"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:background="#267cc5"
        android:visibility="gone">

        <TextView
            android:id="@+id/class_name"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentLeft="true"
            android:layout_alignParentTop="true"
            android:padding="8dp"
            android:textColor="#FFFFFF"
            android:textStyle="bold" />

    </RelativeLayout>

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_below="@id/section_header_class_name">

        <TextView
            android:id="@+id/method_name"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:paddingLeft="8dp"
            android:paddingRight="8dp"
            android:layout_alignParentLeft="true"
            android:layout_alignParentTop="true" />

        <TextView
            android:id="@+id/test_result"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentLeft="true"
            android:paddingLeft="8dp"
            android:paddingRight="8dp"
            android:paddingBottom="8dp"
            android:textSize="@dimen/normal_text"
            android:layout_below="@id/method_name"/>

    </RelativeLayout>

</RelativeLayout>

My custom ViewMatcher is as below:

// Match with the TestItemAdapter getView();
static class TestItemMatcher extends TypeSafeMatcher<View> {

    private final String mExpectedResult;
    private String mActualResult;

    private String className;

    static TestItemMatcher resultStartsWith(String resultString) {
        return new TestItemMatcher(resultString);
    }

    private TestItemMatcher(String resultString) {
        super(TextView.class);
        mExpectedResult = resultString;
    }


    @Override
    public void describeTo(Description description) {
        description.appendText("Test class: " + className + ", ");
        description.appendText("checking the matcher on received view: ");
        description.appendText("with expected=\"" + mExpectedResult + "\", but actual=\"" + mActualResult + "\"");
    }

    @Override
    protected boolean matchesSafely(View item) {

        RelativeLayout relativeLayout = (RelativeLayout) item;
        RelativeLayout childRelativeLayout = (RelativeLayout) relativeLayout.getChildAt(0);

        TextView classNameTextView = (TextView)childRelativeLayout.getChildAt(0);
        className = classNameTextView.getText().toString();
        TextView testResultTextView = item.findViewById(R.id.test_result);
        mActualResult = testResultTextView.getText().toString();
        return mExpectedResult.equals(mActualResult);
    }
}
