I’ve had to remove the divider in an Android ListView several times now, so here’s a quick reminder of myself.
This can be done in XML or in Java by setting the dividerHeight to 0 and the divider to null:
XML
<ListView android:id="@+id/listView" android:layout_width="fill_parent" android:layout_height="fill_parent" android:dividerHeight="0dp" android:divider="@null"/>
Java
ListView listView = (ListView)findViewById(R.id.listView); listView.setDividerHeight(0); listView.setDivider(null);Comments closed
