ExpandableListView
은 LinearLayout
안에 있으며 CustomAdapter
을 사용하여 설정합니다.
해당 하위 항목에 대해 onGroupClick()
메서드를 사용하여 특정 서비스에 요청을 보내고 결과를 String으로 가져온 다음 클릭 한 그룹 항목의 자식 목록을 채 웁니다.ExpandableListView 동적 하위 높이보기
문제는입니다. 서비스 응답이 텍스트보기의 자식보기 텍스트보기로 설정된 후 업데이트 된 높이를 가져올 수 없으므로 linearlayout 컨테이너 높이로 인해 높이가 증가하지 않습니다. 또한 스크롤링 문제가 발생합니다.
비록 목록 하위 항목 XML은 다음과 같이 WRAP_CONTENT
입니다 :
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/root"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:minHeight="@dimen/rowHeight"
android:background="@color/colorLightYellow">
<TextView
android:id="@+id/tvTitle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_marginLeft="@dimen/marginGeneral"
android:layout_toLeftOf="@+id/tvCount"
android:gravity="center_vertical"
android:paddingBottom="@dimen/marginGeneral"
android:paddingTop="@dimen/marginGeneral"
android:text="tvTitle"
android:textColor="@color/colorGray"
android:textSize="@dimen/fontSizeNormal" />
...
</RelativeLayout>
그래서 코드 부분은 나와 함께 작은 장기 체류입니다 :
@Override
public boolean onGroupClick(ExpandableListView parent, View v, final int groupPosition, long id) {
Map<Item, List<ItemDetail>> childList = detailExpandableAdapter.getChildList();
final Item item = detailExpandableAdapter.getGroup(groupPosition);
if (childList.get(item).size() == 0) {
startProgressDialog();
GlobalApplication.getService().getItemDetails(Session.getCurrent().getSessionId(), getItem.item.itemNo, item.name, new ServiceCallback<GetItemDetails>() {
@Override
public void onSuccess(GetItemDetails response) {
stopProgressDialog();
List<ItemDetail> itemDetailList = null;
if (GetItemDetails.isSuccess(response)) {
itemDetailList = response.getItemDetailList();
} else {
itemDetail itemDetail = new ItemDetail();
itemDetail.resultDesc = response.getResult().getResultDesc();
if (StringUtils.isNullOrWhitespace(itemDetail.resultDesc)) {
itemDetail.resultDesc = Result.getGeneralFailResult().getResultDesc();
}
itemDetailList = new ArrayList<ItemDetail>();
itemDetailList.add(itemDetail);
}
if (itemDetailList != null) {
Map<Item, List<ItemDetail>> childList = detailExpandableAdapter.getChildList();
if (childList.containsKey(item)) {
childList.remove(item);
}
childList.put(item, itemDetailList);
detailExpandableAdapter.setChildList(childList);
detailExpandableAdapter.notifyDataSetChanged();
detailExpandableAdapter.notifyDataSetInvalidated();
listViewLastItems.expandGroup(groupPosition);
}
}
@Override
public void onFail() {
stopProgressDialog();
}
});
return false;
}
return false;
}
@Override
public void onGroupExpand(int groupPosition) {
setExpandableListViewHeightStable(listViewLastItems, llListViewItemDetailContainer);
if (lastExpanded != -1 && groupPosition != lastExpanded)
listViewItems.collapseGroup(lastExpanded);
lastExpanded = groupPosition;
}
public void setExpandableListViewHeight(ExpandableListView expandableListView, LinearLayout linearLayoutParent){
try {
ExpandableListAdapter expandableListAdapter = expandableListView.getExpandableListAdapter();
int totalHeight = 0;
int desiredWidth = View.MeasureSpec.makeMeasureSpec(expandableListView.getWidth(), View.MeasureSpec.UNSPECIFIED);
for (int i = 0; i < expandableListAdapter.getGroupCount(); i++) {
View groupItem = expandableListAdapter.getGroupView(i, false, null, expandableListView);
groupItem.measure(desiredWidth, View.MeasureSpec.UNSPECIFIED);
//Logger.debug("recalculateExpandableListViewHeight listItem:"+groupItem.getMeasuredHeight());
totalHeight += groupItem.getMeasuredHeight();
if (expandableListView.isGroupExpanded(i)){
for (int j = 0; j < expandableListAdapter.getChildrenCount(i); j++) {
View listItemChild = expandableListAdapter.getChildView(i, j, false, null, expandableListView);
listItemChild.setLayoutParams(new ViewGroup.LayoutParams(desiredWidth, View.MeasureSpec.UNSPECIFIED));
listItemChild.measure(View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED), View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED));
Logger.debug("recalculateExpandableListViewHeight listItemChild:" + listItemChild.getMeasuredHeight());
totalHeight += listItemChild.getMeasuredHeight();
}
}
}
linearLayoutParent.getLayoutParams().height = totalHeight + (expandableListAdapter.getGroupCount() * expandableListView.getDividerHeight());
linearLayoutParent.requestLayout();
} catch (Exception e) {
Logger.printStackTrace(e);
}
}
업데이트 : 이것이 내가 용기로 사용하는 선형 레이아웃입니다은
<LinearLayout
android:id="@+id/llListViewItemContainer"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="@+id/tvItemDueDate"
android:layout_marginTop="@dimen/marginGeneral"
android:orientation="vertical"/>
업데이트 2 : ExpandableListView를 동적으로 LinearLayout에 추가합니다.
listViewItems = new ExpandableListView(getContext());
listViewItems.setScrollContainer(false);
listViewItems.setDivider(new ColorDrawable(getResources().getColor(R.color.colorLightGray)));
listViewItems.setDividerHeight(UIHelper.convertDptoPixels(1));
listViewItems.setGroupIndicator(null);
listViewItems.setOnGroupClickListener(this);
listViewItems.setOnGroupExpandListener(this);
listViewItems.setOnGroupCollapseListener(this);
//generate empty child list
Map<Item, List<ItemDetail>> childMap = new HashMap<>();
for (Item item : getItems.getItemList()) {
childMap.put(item, new ArrayList<ItemDetail>());
}
detailExpandableAdapter = new detailExpandableAdapter(getActivity(), getItems.getItemList(), childMap);
listViewItems.setAdapter(detailExpandableAdapterF);
listViewItems.removeAllViews();
listViewItems.addView(listViewLastItems);
UIHelper.setExpandableListViewHeightStable(listViewItems, llListViewDetailContainer);
LinearLayout (컨테이너) 대신 RecyclerView를 사용할 수 있습니다. – Sabari
그러면 선형 레이아웃 부모가 scrollView 안에 래핑됩니까? – HourGlass
