ExpandableListView自定義設計

Question

我想自定義ExpandableListView，但我無法自定義孩子。我怎樣才能做一個邊框和填充背景（下面的示例代碼SRC）

我有什麼：

ExpandableListView

<ExpandableListView 
    android:id="@+id/expListviewServices" 
    android:layout_width="match_parent" 
    android:divider="@color/white" 
    android:dividerHeight="10dp" 
    android:childDivider="@color/white" 
    android:layout_height="match_parent" /> 

list_fragment_services_groups.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:paddingLeft="50dp" 
    android:background="@drawable/expandblelistview_background" 
    android:paddingTop="10dp" 
    android:paddingBottom="10dp" 
    android:layout_height="wrap_content"> 

    <ImageView 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:id="@+id/imgServicesGroup" 
     android:src="@drawable/ic_internet" /> 

    <TextView 
     android:layout_width="wrap_content" 
     android:id="@+id/txtServicesGroup" 
     android:textAppearance="?android:attr/textAppearanceLarge" 
     android:textColor="@color/black" 
     android:layout_toRightOf="@id/imgServicesGroup" 
     android:paddingLeft="15dp" 
     android:textStyle="bold" 
     android:layout_height="wrap_content" /> 

</RelativeLayout> 

list_fragment_services_child.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:orientation="vertical" 
    android:layout_width="match_parent" 
    android:layout_marginLeft="40dp" 
    android:background="@color/white" 
    android:layout_height="wrap_content"> 

    <TextView 
     android:layout_width="wrap_content" 
     android:id="@+id/txtServicesChild" 
     android:paddingLeft="50dp" 
     android:paddingTop="5dp" 
     android:paddingBottom="5dp" 
     android:textColor="@color/black" 
     android:layout_height="wrap_content" /> 

</RelativeLayout> 

expandblelistview_background.xml

<shape xmlns:android="http://schemas.android.com/apk/res/android" 
    android:shape="rectangle"> 
    <solid android:color="@color/lightgray" /> 
    <corners android:radius="10dp"/> 
</shape> 

我想要什麼：

地址：

public class ServicesAdapter extends BaseExpandableListAdapter { 

    private static final String TAG = ServicesAdapter.class.getSimpleName(); 
    private ArrayList<HashMap<String, String>> group; 
    ArrayList<ArrayList<HashMap<String, String>>> child; 
    private Context context; 

    private static String GROUP_NAME = "group_name"; 
    private static String GROUP_IMAGE = "group_image"; 
    private static String CHILD_NAME = "child_name"; 

    public ServicesAdapter(Context context, ArrayList<HashMap<String, String>> group, ArrayList<ArrayList<HashMap<String, String>>> child) { 
     this.context = context; 
     this.group = group; 
     this.child = child; 
    } 

    @Override 
    public int getGroupCount() { 
     return group.size(); 
    } 

    @Override 
    public int getChildrenCount(int groupPosition) { 
     return child.get(groupPosition).size(); 
    } 

    @Override 
    public Object getGroup(int groupPosition) { 
     return group.get(groupPosition); 
    } 

    @Override 
    public Object getChild(int groupPosition, int childPosition) { 
     return child.get(groupPosition).get(childPosition); 
    } 

    @Override 
    public long getGroupId(int groupPosition) { 
     return groupPosition; 
    } 

    @Override 
    public long getChildId(int groupPosition, int childPosition) { 
     return childPosition; 
    } 

    @Override 
    public boolean hasStableIds() { 
     return true; 
    } 

    @Override 
    public View getGroupView(int groupPosition, boolean isExpanded, View convertView, ViewGroup parent) { 
     if (convertView == null) { 
      LayoutInflater infalInflater = (LayoutInflater) context 
        .getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
      convertView = infalInflater.inflate(R.layout.list_fragment_services_groups, null); 
     } 

     if (isExpanded) { 
      convertView.setBackgroundResource(R.drawable.expandblelistview_background_selected); 
     } else { 
      convertView.setBackgroundResource(R.drawable.expandblelistview_background); 
     } 

     ImageView imgServicesGroup = (ImageView) convertView.findViewById(R.id.imgServicesGroup); 
     TextView txtServicesGroup = (TextView) convertView.findViewById(R.id.txtServicesGroup); 

     txtServicesGroup.setText(group.get(groupPosition).get(GROUP_NAME)); 
     int imageId = context.getResources().getIdentifier("ic_" + group.get(groupPosition).get(GROUP_IMAGE), "drawable", context.getPackageName()); 
     imgServicesGroup.setImageResource(imageId); 

     return convertView; 
    } 

    @Override 
    public View getChildView(int groupPosition, int childPosition, boolean isLastChild, View convertView, ViewGroup parent) { 

     if (convertView == null) { 
      LayoutInflater infalInflater = (LayoutInflater) context 
        .getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
      convertView = infalInflater.inflate(
        R.layout.list_fragment_services_child, null); 
     } 

     TextView txtServicesChild = (TextView) convertView.findViewById(R.id.txtServicesChild); 
     txtServicesChild.setText(child.get(groupPosition).get(childPosition).get(CHILD_NAME)); 

     return convertView; 
    } 

    @Override 
    public boolean isChildSelectable(int groupPosition, int childPosition) { 
     return false; 
    } 
}
