Rotated TextView in RelativeLayout with Margin - TextView still behaviour like if it's not rotated

Question

I'm trying to do something like the image below, where I have a rotated (90°) TextView with marginLeft related to the ImageView. The problem is, when I increase the TextView value, say 2 to 2000000, it move to the right, behaving like a non-rotated TextView (see the blue square around it). How can I fix it?

Thank you!

Code:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/ll_note"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
 >

<ImageView
    android:id="@+id/iv_flange"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginBottom="10dp"
    android:layout_marginLeft="40dp"
    android:layout_marginRight="10dp"

Even when you rotate your TextView using android:rotaion in xml or myTextView.setRotation() in the Java code, the bounds of the text view will not update to the angle you rotated the text view into. To overcome this you may write a custom TextView that draws itself in the correct angle you require it to. Please check this answer for a starting point.
