The answer depends on the type of View you want to call the method on. If it's e.g. a LinearlLayout, this will do the job:

rv.setInt(R.id.MyView, "setGravity", Gravity.CENTER);

I tested it on a LinearLayout and a TextView and it does work with the layout but not with the TextView. So my assumption would be it's supported by ViewGroup classes only (you can check that assumption yourself by checking the setGravity(int) methods in the Android source for @android.view.RemotableViewMethod annotations).

So if you want to change TextView's gravity programmatically, you need to wrap the TextView in its own LinearLayout and change gravity of the LinearLayout instead, e.g. use this layout:

<LinearLayout
    android:id="@+id/day_header_title_wrapper"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <TextView
        android:id="@+id/day_header_title"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />
</LinearLayout>

and set gravity like this:

rv.setInt(R.id.day_header_title_wrapper, "setGravity", Gravity.CENTER);
