How to set space between listView Items in Android

Question

I tried to use marginBottom on the listView to make space between listView Item, but still the items are attached together.

Is it even possible? If yes, is there a specific way to do it?

My code is below

<LinearLayout
android:id="@+id/alarm_occurences"
android:layout_width="fill_parent" 
android:orientation="vertical"
android:layout_height="fill_parent"
android:background="#EEEEFF"
xmlns:android="http://schemas.android.com/apk/res/android">

<ListView
android:id="@+id/occurences"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
</LinearLayout>

My custom List item:

<com.android.alarm.listItems.AlarmListItem
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent" 
android:background="@drawable/alarm_item_background"
android:layout_marginBottom="10dp"    
>
<CheckedTextView     
    android:id="@android:id/text1"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:gravity="center_vertical"
    android:checkMark="?android:attr/listChoiceIndicatorMultiple"
    android:textSize="20sp"
    android:textStyle="bold"
    android:typeface="serif"
    android:padding="10dp"

/>

</com.android.alarm.listItems.AlarmListItem>

How can I make spacing between list items in this case?

Answer 1

@Asahi pretty much hit the nail on the head, but I just wanted to add a bit of XML for anyone maybe floating in here later via google:

<ListView android:id="@+id/MyListView"
  android:layout_height="match_parent"
  android:layout_width="match_parent"
  android:divider="@android:color/transparent"
  android:dividerHeight="10.0sp"/>

For some reason, values such as "10", "10.0", and "10sp" all are rejected by Android for the dividerHeight value. It wants a floating point number and a unit, such as "10.0sp". As @Goofyahead notes, you can also use display-independent pixels for this value (ie, "10dp").
