Android : Put two textviews above fragment that contains a Google Maps

I have the following code that displays two textviews and below I have a fragment where I display a map of Google Maps. But still I'm not able to display them in this way:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="${relativePackage}.${activityClass}" >


<TextView
    android:id="@+id/textView1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentLeft="true"
    android:layout_alignParentTop="true"
    android:layout_marginLeft="27dp"
    android:layout_marginTop="35dp"
    android:layout_alignParentBottom="true"
    android:text="@string/pos_actual" />

<TextView
    android:id="@+id/txtGeoposition"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignTop="@+id/textView1"
    android:layout_toRightOf="@+id/textView1"
    android:layout_alignParentBottom="true"
    android:layout_above="@+id/map"
    android:textAppearance="?android:attr/textAppearanceLarge" />

<fragment
    android:id="@+id/map"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:layout_above="@+id/textView1"
    class="com.google.android.gms.maps.MapFragment" />

Also I want to limit the height of the fragment for not to fill the rest of the parent layout, just a few pixels of height, because below the map I want to put other controls to display.

How can I achieve this controls to put them in this way?

Thank you in advance
