Android ExpandableListView group的item有间距child间隔不变

   <ExpandableListView

        android:id="@+id/lv"

        android:layout_width="fill_parent"

        android:layout_height="0dp"

        android:layout_weight=""

        android:background="@null"

        android:childDivider="#00000000"

        android:dividerHeight="10dp"

        android:groupIndicator="@null"

        android:listSelector="#00000000" />

android:dividerHeight="10dp"设置的话 group和child都有间距
