two or more nested RelativeLayout

I want to ask, working with two or more nested RelativeLayout. First code looks like picture 1, When I add android:layout_alignParentRight="true" in second RelativeLayout, this looks like picture 2. I want to align text right to second RelativeLayout. Where is my fault?

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="wrap_content"
        android:background="@drawable/background"
        android:layout_he开发者_高级运维ight="wrap_content"
        android:id="@+id/testRL">
        <RelativeLayout
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_alignParentRight="true"
                android:layout_alignParentTop="true"
                android:id="@+id/testRotateLL"
                android:background="@drawable/picture_border_offer_first_page">
                <TextView
                        android:layout_height="wrap_content"
                        android:layout_width="wrap_content"
                        android:text="7000TL"
                        android:textSize="15sp"
                        android:textColor="@android:color/white"
                        android:id="@+id/amountLayoutTV" />
        </RelativeLayout>
</RelativeLayout>

And I add android:layout_alignParentRight="true"

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:background="@drawable/background"
    android:layout_height="wrap_content"
    android:id="@+id/testRL">
    <RelativeLayout
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentRight="true"
            android:layout_alignParentTop="true"
            android:id="@+id/testRotateLL"
            android:background="@drawable/picture_border_offer_first_page">
            <TextView
                    android:layout_height="wrap_content"
                    android:layout_width="wrap_content"
                    android:text="7000TL"
                    android:layout_alignParentRight="true"
                    android:textSize="15sp"
                    android:textColor="@android:color/white"
                    android:id="@+id/amountLayoutTV" />
    </RelativeLayout>
</RelativeLayout>

This question is unanswered. when I updated ADT version, this problem solved. There was a bug, I think.

I suggest you to check version of ADT sometimes...

In the first RelativeLayout you have:

android:layout_width="wrap_content"
android:layout_height="wrap_content"

You probably want:

android:layout_width="fill_parent"
android:layout_height="fill_parent"
