I would like to inset a RecyclerView ItemDecorator divider to left align with a TextView (the item title) inside the list element that is constrained to be 72dp from the parent left side. Something like we see [here](https://material.io/guidelines/components/dividers.html#dividers-types-of-dividers) in the Google Material Design Docs. I assume that I need to somehow reference the layout params on the titleTextView, but am not sure how to do that from my ItemDecorator code, as I seem to be able to only get the params which is the ConstraintLayout, and not the textview itself. Any help or pointers in the right direction would be greatly appreciated! The relevant ItemDecorator code, where I try to get the textView param looks something like this:

```
        for (int i = 0; i < recyclerView.getChildCount() - 1; ++i) {
            View child = recyclerView.getChildAt(i);
            RecyclerView.LayoutParams params =(RecyclerView.LayoutParams) child.getLayoutParams();
//this just gives me the constraint layout, not the TextView params, how to reference the textViewParams!?

```

The RecyclerView looks like this:

```
        <android.support.v7.widget.RecyclerView
        xmlns:app="http://schemas.android.com/apk/res-auto"
        xmlns:tools="http://schemas.android.com/tools"
        android:id="@+id/myList"
        android:name="com.example.Something"
        android:layout_width="0dp"
        android:layout_height="0dp"
        app:layoutManager="LinearLayoutManager"
        tools:context=".controllers.fragments.ExampleFragment"
        tools:listitem="@layout/fragment_something"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintBottom_toBottomOf="parent" />

```

The list item xml is a constraint layout with some TextViews, and the relevant portion looks like this:

```
    <android.support.constraint.ConstraintLayout
        android:layout_width="match_parent"
        android:layout_height="72dp">

    <ImageView
        android:id="@+id/myImageView"
        android:layout_width="32dp"
        android:layout_height="32dp"
        android:layout_marginLeft="16dp"
        app:layout_constraintLeft_toLeftOf="parent"
        tools:src="@drawable/ic_menu_manage"
        android:src="@drawable/ic_menu_manage"
        app:layout_constraintTop_toTopOf="parent"
        android:layout_marginTop="16dp"
        app:layout_constraintBottom_toBottomOf="parent"
        android:layout_marginBottom="16dp" />

    <TextView
        android:id="@+id/titleTextView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginBottom="4dp"
        android:layout_marginLeft="72dp"
        android:layout_marginTop="20dp"
        android:text="MyTitle"
        android:textAppearance="@style/TextAppearance.AppCompat.Subhead"
        android:textStyle="bold"
        app:layout_constraintBottom_toTopOf="@+id/textView5"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        tools:text="SampleTitle" />

    ...

    </android.support.constraint.ConstraintLayout>

```
