[General Questions and Answers] Edwinem:
Hi guys, i have the following code:

// I deleted the "http: //" (without whitespaces) from the links in the relativelayout namespace in order to post it (i'm newbie), if you want to try it remember it.

<RelativeLayout xmlns:android="schemas.android.com/apk/res/android"
xmlns:tools="schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context="com.oscarvicente.sieteymedia.MainActivity" >

<LinearLayout
android:id="@+id/cartas"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:layout_above="@id/botones"
android:layout_marginLeft="5dp"
android:layout_marginRight="5dp"
android:layout_marginTop="5dp"
android:orientation="vertical" >

<HorizontalScrollView
android:id="@+id/scrollJugador"
android:layout_width="match_parent"
android:layout_height="wrap_content" >

<LinearLayout
android:id="@+id/jugador"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal" />
</HorizontalScrollView>

<HorizontalScrollView
android:id="@+id/scrollBanca"
android:layout_width="match_parent"
android:layout_height="318dp" >

<LinearLayout
android:id="@+id/banca"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="5dp"
android:layout_marginTop="5dp"
android:orientation="horizontal" />
</HorizontalScrollView>
</LinearLayout>

<LinearLayout
android:id="@+id/botones"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_above="@id/botonNuevaPartida"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true"
android:layout_marginBottom="5dp"
android:layout_marginTop="5dp"
android:orientation="horizontal" >

<Button
android:id="@+id/botonCarta"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="@string/botonCarta" />

<Button
android:id="@+id/botonPlantarse"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="@string/botonPlantarse" />
</LinearLayout>

<Button
android:id="@+id/botonNuevaPartida"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignLeft="@id/botones"
android:layout_alignParentBottom="true"
android:layout_alignRight="@id/botones"
android:text="@string/botonNuevaPatida" />

</RelativeLayout>

It's seems correct, but eclipse says that in these lines are an error:

18- android:layout_above="@id/botones"

55- android:layout_above="@id/botonNuevaPartida"

The error is:

Error: No resource found that matches the given name (at 'layout_above' with value '@id/botonNuevaPartida').

but the resource exists.

I cleaned up the project, refreshed, but there's no way to solve the problem, anyone knows what's wrong in this code?

P.D: I thing this question goes here.

P.D2: Thank all for read and help! :D
