expandablelistview不同風格的展開/摺疊

我試圖得到一個定製Expandablelistview，有不同的佈局狀態展開/摺疊...expandablelistview不同風格的展開/摺疊

適配器

@Override 

public View getGroupView(int groupPosition, boolean isExpanded, View convertView, ViewGroup parent) { 

String headerTitle = ((User) getGroup(groupPosition)).getName(); 
if (convertView == null) { 
    LayoutInflater infalInflater = (LayoutInflater) this.con.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 

    if(isExpanded) { 
     Log.e("DBG", "isExpanded"); 
     convertView = infalInflater.inflate(R.layout.expanablelistview_header_expanded, parent, false); 
    } else { 
     Log.e("DBG", "isNotExpanded"); 
     convertView = infalInflater.inflate(R.layout.expanablelistview_header_collapse, parent, false); 
    } 
} 

TextView lblListHeader = (TextView) convertView.findViewById(R.id.tv_user); 
lblListHeader.setTypeface(null, Typeface.BOLD); 
lblListHeader.setText(headerTitle); 

return convertView; 
}

expanablelistview_header_collapse.xml

<?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="match_parent" 
    android:background="@color/transparent" 
    android:orientation="vertical" > 

    <LinearLayout 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:background="@drawable/xml_border" 
     android:orientation="vertical" > 

     <TextView 
      android:id="@+id/tv_user" 
      android:textSize="20sp" 
      android:layout_width="match_parent" 
      android:layout_height="wrap_content" /> 

    </LinearLayout> 

    <View 
     android:background="@color/transparent" 
     android:layout_width="match_parent" 
     android:layout_height="10dp" /> 

</LinearLayout>

expanablelistview_header_expanded.xml

<?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="match_parent" 
    android:background="@drawable/xml_border_top" 
    android:orientation="vertical" > 

    <TextView 
     android:id="@+id/tv_user" 
     android:textSize="20sp" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" /> 

</LinearLayout>

這是我的嘗試，但這種梅索德只呼籲啓動不是在擴展狀態變更...

謝謝你，你的想法！

一舉兩得佈局包含哪些佈局？ – 2015-03-02 14:24:14

添加Layout xml的 – Flo 2015-03-02 14:37:28

而不是更改佈局，您可以隱藏並顯示您的「視圖」並更改線性佈局的背景。 – 2015-03-02 14:40:33

的問題是

if (convertView == null)

謝謝！

嘗試加載在MainActivity佈局在

<ExpandableListView Obj>.setOnGroupExpandListener();

和

<ExpandableListView Obj>.setOnGroupCollapseListener();
