實現效果圖：
expandableListView groupIndicator 圖片默認是在左邊，而且比較難看，而我要的是實現groupIndicator 在右邊自定義圖片，
換圖片
最簡單的就是直接copy 系統
<style name="Widget.ExpandableListView" parent="Widget.ListView">
<item name="android:groupIndicator">@android:drawable/expander_group</item>
<item name="android:indicatorLeft">?android:attr/expandableListPreferredItemIndicatorLeft</item>
<item name="android:indicatorRight">?android:attr/expandableListPreferredItemIndicatorRight</item>
<item name="android:childDivider">@android:drawable/divider_horizontal_dark_opaque</item>
</style>
看到這個沒有
<item name="android:groupIndicator">@android:drawable/expander_group</item>
我們只要把這個給換了，那 groupIndicator也就跟著變了。但是改這個有個問題顯示出來的
顯示的效果不是很好，圖片有被拉升過，系統自己是做了個.9圖片。我們已可以
2.做一張.9圖片
在你eclipse 的解壓目錄下，找到\sdk\tools\
我的是D:\android-IDE-eclipse-64\adt-bundle-windows-x86-20130522\sdk\tools
在這個目錄下有一個draw9patch.bat的批處理文件。我們要用它做.9圖，雙擊直接打開。直接將你要做成.9 的原圖直接拉進工具。
3.創建 Indicator selector expander_group.xml 文件
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:state_expanded="true"
android:drawable="@drawable/up" />
<item
android:drawable="@drawable/down" />
</selector>
4.放一張圖片到你的res目錄下這里我直接用系統的
<item name="android:childDivider">@android:drawable/divider_horizontal_dark_opaque</item>
這個是一張圖片
5.在自己的style。xml里寫一個
<style name="ExpandableListView" parent="android:Widget.ListView">
<item name="android:groupIndicator">@drawable/expander_group</item>
<item name="android:indicatorLeft">?android:attr/expandableListPreferredItemIndicatorLeft</item>
<item name="android:indicatorRight">?android:attr/expandableListPreferredItemIndicatorRight</item>
<item name="android:childDivider">@drawable/divider_horizontal_dark_opaque</item>
</style>
這樣我們就自己定義好了expandable的style
6.加載自己的style
<ExpandableListView
android:id="@+id/expandableListView1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true" >
</ExpandableListView>
7.在activity中設置 Indicator位置
expandablelistView 提供一個方法設置位置
Display dp = getWindowManager().getDefaultDisplay();
int width = dp.getWidth();
lv.setIndicatorBounds(width-50, width);
運行完結果：
不知道什么原因還是有點拉伸，效果不是很好，但又要實現title圖片不回被拉伸放大這樣的效果；所以我就只能把圖標給屏蔽了，然后在groupItem的布局加一個ImageView，用ImageView自己實現。
<ExpandableListView
android:id="@+id/exlv_select_binddev"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:groupIndicator="@null"
android:childIndicator="@null"
>
</ExpandableListView>
這樣就把他自帶的圖標給屏蔽了，然后直接在groupitem布局加上一個ImageView，再做一個Childitem的布局，布局我直接設4個button，自由發揮了。
然后在適配器上getgroupView 設置父布局，在getChildView設置子布局。和listView的差不多。
現在要做的就是設置監聽
監聽ImageView expandableListView 的點擊事件，這里我是點圖片展開和關閉Child，長點擊expandableListView 也展開和關閉Child，點擊進入另一個界面。
監聽ImageView的點擊事件，這里關鍵是保存position。直接寫一個內部類保存position
class ImageListener implements OnClickListener {
private int groupPosition;
public ImageListener(int groupPosition)
{
this.groupPosition = groupPosition;
}
@Override
public void onClick( View v )
{
Toast.makeText(ExpandableActivity.this, " p_w_picpath groupPosition : " + groupPosition, Toast.LENGTH_SHORT)
.show();
if (mlist.isGroupExpanded(groupPosition))//是否展開
{
mlist.collapseGroup(groupPosition);//設置關閉
}
else
{
mlist.expandGroup(groupPosition);//設置展開
}
}
}
監聽長點擊事件
mlist.setOnItemLongClickListener(new OnItemLongClickListener() {
public boolean onItemLongClick( AdapterView<?> parent, View childView, int flatPos, long id )
{
if (ExpandableListView.getPackedPositionType(id) == ExpandableListView.PACKED_POSITION_TYPE_GROUP)
{
long position = ((ExpandableListView) parent).getExpandableListPosition(flatPos);
int groupPosition = ExpandableListView.getPackedPositionGroup(position);
int childPosition = ExpandableListView.getPackedPositionChild(position);
System.out.println(groupPosition + childPosition + " :groupPosition childPosition" + flatPos + " "
+ id);
if (mlist.isGroupExpanded(groupPosition))
{
mlist.collapseGroup(groupPosition);
}
else
{
mlist.expandGroup(groupPosition);
}
return true;
}
else if (ExpandableListView.getPackedPositionType(id) == ExpandableListView.PACKED_POSITION_TYPE_CHILD)
{
long position = ((ExpandableListView) parent).getExpandableListPosition(flatPos);
int groupPosition = ExpandableListView.getPackedPositionGroup(position);
int childPosition = ExpandableListView.getPackedPositionChild(position);
System.out.println(childPosition + " :groupPosition");
return true;
}
return false;
}
});
獲取點擊事件
mlist.setOnGroupClickListener(new OnGroupClickListener() {
@Override
public boolean onGroupClick( ExpandableListView parent, View v, final int groupPosition, long id )
{
Toast.makeText(ExpandableActivity.this, " click groupPosition : " + groupPosition + " id : " + id,
Toast.LENGTH_SHORT).show();
return true;
}
});
這樣就可以了
Child 的點擊事件那就比較簡單了，直接和ImageView的點擊事件一樣處理，或者直接寫死了，Child是橫向的，也只有4個不多。
ch.tv_choose.setOnClickListener(new OnClickListener() {
@Override
public void onClick( View v )
{
// TODO 子控件進入
onChildChick(0, FatherItem);
}
});
public void onChildChick( int childItemid, int fatherItemid )
{
// TODO 接收child
Toast.makeText(this, " childItemid : " + childItemid + " fatherItemid : " + fatherItemid, Toast.LENGTH_SHORT)
.show();
}
這樣就搞定了

}groupView 布局：這里最好用relativeLayout,之前用linearlayout不能實現點擊p_w_picpathView沒反應回去不到事件，后面監聽觸摸事件，那做法更麻煩，后來改用relativelayout后就可以了。
然后設置 RelativeLayout 設置 android:descendantFocusability="blocksDescendants"
要獲取點擊事件的 ImageView設置 android:focusable="false"就行了；
