Q:

Listview ocupar toda a tela

Tenho este listview
main.xml
 <ListView
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:id="@+id/praias"
    android:layout_above="@+id/adView"
    />

Eu tava Querendo que o item deste listview ocupasse a largura total , ele ja esta como fillparent então eu acho que ele deveria estar ocupando a tela toda ne. Como eu faço para não ficar esses espaços em branco nas bordas
itens.xml

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

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/hello_world" />

<LinearLayout
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentLeft="true"
    android:layout_gravity="center_horizontal"
    android:layout_marginTop="0dp" >

    <ListView
        android:id="@+id/listViewIntervalDetails"
        android:layout_width="fill_parent"
        android:layout_height="150dp"
        android:layout_gravity="center_horizontal"
        android:background="@drawable/checknormal"
        android:cacheColorHint="#00000000"
        android:divider="#b5b5b5"
        android:dividerHeight="1dp"
        android:longClickable="true"
        android:padding="2dp" >
    </ListView>
</LinearLayout>
