can not put the ViewPagerIndicator on the ViewPager

Question

i used https://github.com/JakeWharton/Android-ViewPagerIndicator ,the lib is very cool,but when i used i meet a question: at the simple_circles.xml :

<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">

<android.support.v4.view.ViewPager
    android:id="@+id/pager"
    android:layout_width="fill_parent"
    android:layout_height="0dp"
    android:layout_weight="1"
    />
<com.viewpagerindicator.CirclePageIndicator
    android:id="@+id/indicator"
    android:padding="10dip"
    android:layout_height="wrap_content"
    android:layout_width="fill_parent"
    />
</LinearLayout>

i modify the code :

 <LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">

 <com.viewpagerindicator.CirclePageIndicator
    android:id="@+id/indicator"
    android:padding="10dip"
    android:layout_height="wrap_content"
    android:layout_width="fill_parent"
    />
<android.support.v4.view.ViewPager
    android:id="@+id/pager"
    android:layout_width="fill_parent"
    android:layout_height="0dp"
    android:layout_weight="1"
    />

</LinearLayout>

it give me CirclePageIndicator cannot be cast to android.support.v4.view.ViewPager

edit:who give me -1, can you give some reason.i want to name-calling

I have tested it and put it as per ur xml..but it gave me same error...and then i reverted back and it ran..!I think we cannot put indicator above the viewpager using this library...@pengwang — TheFlash, Aug 23 '13 at 08:54

  <LinearLayout
           xmlns:android="http://schemas.android.com/apk/res/android"
           android:orientation="vertical"
           android:layout_width="fill_parent"
           android:layout_height="fill_parent">

           <com.viewpagerindicator.CirclePageIndicator
              android:id="@+id/indicator"
              android:padding="10dip"
               android:layout_height="wrap_content"
              android:layout_width="fill_parent"
            />
       <android.support.v4.view.ViewPager
          xmlns:android="http://schemas.android.com/apk/res/android"
          android:id="@+id/pager"
           android:layout_width="fill_parent"
          android:layout_height="0dp"
          android:layout_weight="1"
      />

  </LinearLayout>
