至於該效果如何? 就是個可以展開/收起的一個listview(視覺效果不錯)
------------------------------------------------------------------------------------------
首先建立一個主要的xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/linear"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<com.daniel.exandableListview.AnimatedExpandableListView
android:id="@+id/listView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:choiceMode="singleChoice"
android:listSelector="@drawable/selector_list_item"
/>
</RelativeLayout>
然後:
group_item.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:orientation="vertical"
android:paddingRight="10dp"
android:paddingLeft="40dp">
<TextView
android:id="@+id/textTitle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:paddingBottom="10dp"
android:paddingTop="10dp"
android:textAppearance="?android:attr/textAppearanceLarge"
/>
<!-- android:textColor="#FFFFFF" -->
</LinearLayout>
list_item.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:orientation="vertical"
android:paddingRight="10dp"
android:paddingLeft="50dp">
<TextView
android:id="@+id/textTitle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceLarge"
/>
<!-- android:textColor="#FFFFFF" -->
<TextView
android:id="@+id/textHint"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceSmall"
android:textColor="#1874CD" />
</LinearLayout>
最後要增加一個Java檔:

/**
* This class defines an ExpandableListView which supports animations for
* collapsing and expanding groups.
*/
public class AnimatedExpandableListView extends ExpandableListView {
/*
* A detailed explanation for how this class works:
*
* Animating the ExpandableListView was no easy task. The way that this
* class does it is by exploiting how an ExpandableListView works.
*
* Normally when {@link ExpandableListView#collapseGroup(int)} or
* {@link ExpandableListView#expandGroup(int)} is called, the view toggles
* the flag for a group and calls notifyDataSetChanged to cause the ListView
* to refresh all of it's view. This time however, depending on whether a
* group is expanded or collapsed, certain childViews will either be ignored
* or added to the list.
*
* Knowing this, we can come up with a way to animate our views. For
* instance for group expansion, we tell the adapter to animate the
* children of a certain group. We then expand the group which causes the
* ExpandableListView to refresh all views on screen. The way that
* ExpandableListView does this is by calling getView() in the adapter.
* However since the adapter knows that we are animating a certain group,
* instead of returning the real views for the children of the group being
* animated, it will return a fake dummy view. This dummy view will then
* draw the real child views within it's dispatchDraw function. The reason
* we do this is so that we can animate all of it's children by simply
* animating the dummy view. After we complete the animation, we tell the
* adapter to stop animating the group and call notifyDataSetChanged. Now
* the ExpandableListView is forced to refresh it's views again, except this
* time, it will get the real views for the expanded group.
*
* So, to list it all out, when {@link #expandGroupWithAnimation(int)} is
* called the following happens:
*
* 1. The ExpandableListView tells the adapter to animate a certain group.
* 2. The ExpandableListView calls expandGroup.
* 3. ExpandGroup calls notifyDataSetChanged.
* 4. As an result, getChildView is called for expanding group.
* 5. Since the adapter is in "animating mode", it will return a dummy view.
* 6. This dummy view draws the actual children of the expanding group.
* 7. This dummy view's height is animated from 0 to it's expanded height.
* 8. Once the animation completes, the adapter is notified to stop
* animating the group and notifyDataSetChanged is called again.
* 9. This forces the ExpandableListView to refresh all of it's views again.
* 10.This time when getChildView is called, it will return the actual
* child views.
*
* For animating the collapse of a group is a bit more difficult since we
* can't call collapseGroup from the start as it would just ignore the
* child items, giving up no chance to do any sort of animation. Instead
* what we have to do is play the animation first and call collapseGroup
* after the animation is done.
*
* So, to list it all out, when {@link #collapseGroupWithAnimation(int)} is
* called the following happens:
*
* 1. The ExpandableListView tells the adapter to animate a certain group.
* 2. The ExpandableListView calls notifyDataSetChanged.
* 3. As an result, getChildView is called for expanding group.
* 4. Since the adapter is in "animating mode", it will return a dummy view.
* 5. This dummy view draws the actual children of the expanding group.
* 6. This dummy view's height is animated from it's current height to 0.
* 7. Once the animation completes, the adapter is notified to stop
* animating the group and notifyDataSetChanged is called again.
* 8. collapseGroup is finally called.
* 9. This forces the ExpandableListView to refresh all of it's views again.
* 10.This time when the ListView will not get any of the child views for
* the collapsed group.

準備工作都完成以後,我們就可以來使用這個expandable listview,但是很顯然還不知道該如何使
用,所以現在就來教學囉!
這邊是用一個分頁(fragment)來做個listview,所以寫在oncreateview()裡面,
首先是標題:
標題使用String[] Title_big 來建立標題集合
中標與小標(或註解)則是使用ChildItem 來建立(這裡是用switch case來判別每一個中標/註解放
甚麼東西)
有了大標題/中標題+註解之後,接下來的問題就是如何點選以後觸發事件??
listView.setOnChildClickListener(new OnChildClickListener(){
public boolean onChildClick(ExpandableListView parent, View v,
int groupPosition, int childPosition, long id) {
int index = parent.getFlatListPosition(ExpandableListView.getPackedPositionForChild(groupPosition, childPosition));
parent.setItemChecked(index, true);
switch (groupPosition) {
這一段就是讓你的中標題能觸發事件,我們用switch...case來取得groupPosition
然後再去裡面細分childPosition,最後才在裡面寫觸發事件!
