        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="New Text 1" />

    <TextView
        android:id="@+id/textView2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="New Text 2" />

    <TextView
        android:id="@+id/textView3"

Answer 1

According to the implementation of FrameLayout bringChildToFront

public void bringChildToFront(View child) {
    int index = indexOfChild(child);
    if (index >= 0) {
        removeFromArray(index);
        addInArray(child, mChildrenCount);
        child.mParent = this;
        requestLayout();
        invalidate();
    }
}

you should be able to retrieve the view you are looking for with

frameLayoutInstance.getChildAt(frameLayoutInstance.getChildCount() - 1).getId()
