How to set space between listView Items in Android
@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").
Although the solution by Nik Reiman DOES work, I found it not to be an optimal solution for what I wanted to do. Using the divider to set the margins had the problem that the divider will no longer be visible so you can not use it to show a clear boundary between your items. Also, it does not add more "clickable area" to each item thus if you want to make your items clickable and your items are thin, it will be very hard for anyone to click on an item as the height added by the divider is not part of an item.
Fortunately I found a better solution that allows you to both show dividers and allows you to adjust the height of each item using not margins but padding. Here is an example:
ListView
<ListViewandroid:id="@+id/listView"android:layout_width="fill_parent"android:layout_height="fill_parent"/>ListItem
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:paddingBottom="10dp" android:paddingTop="10dp" > <TextView android:id="@+id/textView" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:text="Item" android:textAppearance="?android:attr/textAppearanceSmall" /></RelativeLayout>
