I have two admob advertisement top and bottom in android

Question

I have two advertisement on the same page but i want to create one advertisement.

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/background1"
    tools:context=".Search">

    <RelativeLayout 
        android:id="@+id/RelativeLayout1"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:orientation="vertical">

        <com.google.ads.AdView 
            android:id="@+id/adView"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentBottom="true"
            android:layout_alignParentLeft="true"
            ads:adSize="SMART_BANNER"
            ads:adUnitId="MY - ID"
            ads:loadAdOnCreate="true"/>

        <ListView
            android:id="@+id/listView1"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_alignParentLeft="true"
            android:layout_alignParentTop="true" 
            android:scrollingCache="false"
            android:layout_above="@+id/adView">
       </ListView>
    </RelativeLayout>
</RelativeLayout>

I added the advertisement this way but i guess i have to add java code for this advertisement.However,if i add java code i have two advertisement top and bottom. xml code provides bottom advertisement to show advertisement.xml code is enough to add advertisement ?

Java code is here :

RelativeLayout RelativeLayout1 = (RelativeLayout)findViewById(R.id.RelativeLayout1);
AdView adView=new AdView(this,AdSize.SMART_BANNER,"MY - ID");
RelativeLayout1.addView(adView);
AdRequest request = new AdRequest();
adView.loadAd(request);

Based on the comments you replied,

Yes, you only need one or the other.

You do not need both .

To explain the code below I have added comments:

//Obtains your main layout.
RelativeLayout RelativeLayout1 = (RelativeLayout)findViewById(R.id.RelativeLayout1);
//Creates a new AdView
AdView adView=new AdView(this,AdSize.SMART_BANNER,"MY - ID");
//Adds this new adView, to your page
RelativeLayout1.addView(adView);
//Gets a new ad request
AdRequest request = new AdRequest();
//Tells the new adView to show the ad.
adView.loadAd(request);

From this, we can see that it is creating a new AdView , adding it to the page, then loading an ad.

Where-as, using just the xml, an Adview already exists.. So there is no reason to create a new one. and having ads:loadAdOnCreate="true" in xml, loads the ad for you.

They are two ways, of achieving the same thing.

ps I prefer the xml way of doing it.
