Can you help me identify why there is a space between the group and the child? In my case I want spaces between all groups and the child should be right below the group with no space (but of course space to the next group. My problem looks like this:
我已将组分隔符设置为此可绘制对象（expandable_list_group_divider）：
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<size android:height="10dp"/>
</shape>
以及子分隔符（@drawable/expandable_list_child_divider）：
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<size android:height="0dp"/>
</shape>
我在 xml 中定义了这样的布局（它是一个复合控件）：
<com.jws.MyExpandableListView
android:id="@+id/expList"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="5dp"
android:layout_marginLeft="15dp"
android:layout_marginRight="15dp"
android:scrollbars="none"
android:divider="@drawable/expandable_list_group_divider"
android:childDivider="@drawable/expandable_list_child_divider"/>
自定义视图类：
public class MyExpandableListView extends ExpandableListView {
protected ArrayList<Departure> departures;
public MyExpandableListView(Context context, AttributeSet attrs) {
super(context, attrs);
setGroupIndicator(null);
setChildIndicator(null);
setHorizontalFadingEdgeEnabled(true);
setVerticalFadingEdgeEnabled(true);
setFadingEdgeLength(60);
departures = new ArrayList<Departure>();
this.setAdapter(new MyExpandableListAdapter(context, this, departures));
}
}
最后是可扩展列表适配器
public class DeparturesExpandableListAdapter extends BaseExpandableListAdapter {
private final int DIVIDER_HEIGHT = 20;
private LayoutInflater inflater;
private ArrayList<Departure> departures;
private Context context;
private ExpandableListView expListView;
public DeparturesExpandableListAdapter(Context context, ExpandableListView expListView, ArrayList<Departure> departures)
{
this.context = context;
inflater = (LayoutInflater) context.getSystemService(context.LAYOUT_INFLATER_SERVICE);
this.departures = departures;
this.expListView = expListView;
}
// This Function used to inflate parent rows view
@Override
public View getGroupView(int groupPosition, boolean isExpanded, View convertView, ViewGroup parentView)
{
final Departure departure = departures.get(groupPosition);
if(!isExpanded)
expListView.setDividerHeight(DIVIDER_HEIGHT);
else
expListView.setDividerHeight(-4);
expListView.setFooterDividersEnabled(false);
// Inflate grouprow.xml file for parent rows
convertView = inflater.inflate(R.layout.view_departure_overview, parentView, false);
//Data handling in the view...
return convertView;
}
// This Function used to inflate child rows view
@Override
public View getChildView(int groupPosition, int childPosition, boolean isLastChild,
View convertView, ViewGroup parentView)
{
final Departure departure = departures.get(groupPosition);
if(isLastChild)
expListView.setDividerHeight(DIVIDER_HEIGHT);
// Inflate childrow.xml file for child rows
convertView = inflater.inflate(R.layout.view_departure_details, parentView, false);
//Data handling...
return convertView;
}
@Override
public Object getChild(int groupPosition, int childPosition)
{
return departures.get(groupPosition);
}
//Call when child row clicked
@Override
public long getChildId(int groupPosition, int childPosition)
{
return childPosition;
}
@Override
public int getChildrenCount(int groupPosition)
{
return 1;
}
@Override
public Object getGroup(int groupPosition)
{
return departures.get(groupPosition);
}
@Override
public int getGroupCount()
{
if(departures != null)
return departures.size();
return 0;
}
//Call when parent row clicked
@Override
public long getGroupId(int groupPosition)
{
return groupPosition;
}
@Override
public void notifyDataSetChanged()
{
// Refresh List rows
super.notifyDataSetChanged();
}
@Override
public boolean isEmpty()
{
return ((departures == null) || departures.isEmpty());
}
@Override
public boolean isChildSelectable(int groupPosition, int childPosition)
{
return false;
}
@Override
public boolean hasStableIds()
{
return false;
}
@Override
public boolean areAllItemsEnabled()
{
return true;
}
}

这是经过测试并被证明有效的，我什至想在几个月后回到这个问题，因为其他方法都没有给我带来我想要的结果。这些完全按照OP（和我自己）想要的方式显示
这是我的组或类别或其他什么。基本上，第一个线性布局只是视图的包装器，充当类别之间的间隔符，然后是另一个处理我所有格式的线性布局
在 ExpandableListView（未显示）中，我将分隔线高度设置为 0。间距由视图处理
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<View
android:layout_width="fill_parent"
android:layout_height="6dp"
android:background="@android:color/transparent"/>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:padding="8dp"
android:background="#50601CBA">
<TextView
android:id="@+id/lblListHeader"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:textSize="17dp"
android:textColor="#FFFFFF" />
</LinearLayout>
</LinearLayout>
然后在孩子身上我有这个。
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="55dip"
android:orientation="vertical" >
<TextView
android:id="@+id/lblListItem"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textSize="12sp"
android:paddingTop="5dp"
android:paddingBottom="5dp"
android:textColor="#FFFFFF"
android:background="#50601CBA"
/>
</LinearLayout>
