CWAC合并适配器出现问题：https://github.com/commonsguy/cwac-merge

当我一个接一个地添加视图和适配器时,这种方法很好用,但是当我尝试一个接一个地添加两个标题时,它崩溃了.这是我的工作：

这是第一个标题的布局：

<?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="horizontal"    androID:weightSum="7"    androID:baselineAligned="false" >    <linearLayout        androID:ID="@+ID/unsynced_layoutt"        androID:layout_wIDth="0dp"        androID:layout_height="match_parent"        androID:layout_weight="6"        androID:orIEntation="vertical" >        <VIEw            androID:layout_wIDth="match_parent"            androID:layout_height="3dp"            androID:background="@color/greenish" />        <TextVIEw            androID:ID="@+ID/unsynced_txt"            androID:layout_wIDth="match_parent"            androID:layout_height="wrap_content"            androID:layout_marginBottom="10dp"            androID:gravity="center"            androID:text="@string/unsynced_txt" />        <TextVIEw            androID:layout_wIDth="match_parent"            androID:layout_height="wrap_content"            androID:gravity="center"            androID:text="@string/lorem_ipsum" />        <VIEw            androID:layout_wIDth="match_parent"            androID:layout_height="3dp"            androID:layout_gravity="bottom"            androID:background="@color/greenish" />    </linearLayout>    <linearLayout        androID:orIEntation="vertical"        androID:layout_weight="1"        androID:ID="@+ID/sync_close_notification"        androID:layout_wIDth="0dp"        androID:layout_height="match_parent"        androID:background="@color/grey_bcknd">        <Imagebutton            androID:ID="@+ID/menu_btn"            androID:layout_wIDth="wrap_content"            androID:layout_height="fill_parent"            androID:layout_gravity="center"            androID:layout_marginleft="10dp"            androID:layout_marginRight="15dp"            androID:background="@null"            androID:contentDescription="@string/something"            androID:src="@drawable/notification_close_x_green" />    </linearLayout></linearLayout>

第二个标题的布局：

<?xml version="1.0" enCoding="utf-8"?><relativeLayout xmlns:androID="http://schemas.androID.com/apk/res/androID"    androID:layout_wIDth="wrap_content"    androID:layout_height="wrap_content"    androID:background="@color/grey_bcknd"    androID:orIEntation="vertical" >    <VIEw        androID:ID="@+ID/top_line"        androID:layout_wIDth="match_parent"        androID:layout_height="1dp"        androID:Alpha="0.25"        androID:background="@color/grey_line" />    <TextVIEw        androID:ID="@+ID/receipt_header_txt"        androID:layout_wIDth="wrap_content"        androID:layout_height="wrap_content"        androID:layout_below="@+ID/top_line"        androID:layout_marginleft="10dp"        androID:text="@string/active_folders"        androID:textcolor="#B4AA9E" />    <VIEw        androID:layout_wIDth="match_parent"        androID:layout_height="1dp"        androID:layout_alignParentBottom="true"        androID:layout_below="@+ID/receipt_header_txt"        androID:Alpha="0.25"        androID:background="@color/grey_line" /></relativeLayout>

这是我尝试实际添加的地方：

all_adapter = new MergeAdapter();        final VIEw notification = inflater                .inflate(R.layout.unsynced_layout, null);        TextVIEw notification_txt = (TextVIEw) notification.findVIEwByID(R.ID.unsynced_txt);        notification_txt.setText("You have "+unsynced_nr+" unsynced items");        all_adapter.addVIEw(notification_txt);        for(int i=0;i<dates.size();i++){            System.out.println("HERE "+i);            VIEw header1 = inflater                    .inflate(R.layout.receipt_List_header, null);            TextVIEw date_header_txt = (TextVIEw) header1.findVIEwByID(R.ID.receipt_header_txt);            date_header_txt.setText(dates.get(i));            all_adapter.addVIEw(header1);            ReceiptDataSource recs1 = new ReceiptDataSource(globalVIEw.getContext());            recs1.open();            ArrayList<Receipt> currentReceipts = recs.findReceiptsByDate(dates.get(i), folder_ID);            recs1.close();            //ReceiptAdapter folder_receipts = new ReceiptAdapter(getActivity(), R.layout.receipt_item, R.layout.receipt_incomplete_item, currentReceipts);            ReceiptCustomAdapter folder_receipts = new ReceiptCustomAdapter(globalVIEw.getContext(), R.layout.receipt_pager,                    currentReceipts, getActivity().getSupportFragmentManager());            all_adapter.addAdapter(folder_receipts);        }

和堆栈跟踪：

08-06 11:54:15.558: E/AndroIDRuntime(20408): FATAL EXCEPTION: main08-06 11:54:15.558: E/AndroIDRuntime(20408): java.lang.classCastException: androID.Widget.linearLayout$LayoutParams cannot be cast to androID.Widget.AbsListVIEw$LayoutParams08-06 11:54:15.558: E/AndroIDRuntime(20408):    at androID.Widget.ListVIEw.measureScrapChild(ListVIEw.java:1170)08-06 11:54:15.558: E/AndroIDRuntime(20408):    at androID.Widget.ListVIEw.measureHeightOfChildren(ListVIEw.java:1252)

如果我评论这一行：

all_adapter.addVIEw(notification_txt);

代码不再崩溃了.

任何建议高度赞赏,谢谢.

解决方法:

因为MergeAdapter需要AbsListVIEw.LayoutParams,所以您遇到了此问题.尝试这个：

final VIEw notification = inflater.inflate(R.layout.unsynced_layout, null);TextVIEw notification_txt = (TextVIEw) notification.findVIEwByID(R.ID.unsynced_txt);notification_txt.setText("You have "+unsynced_nr+" unsynced items");AbsListVIEw.LayoutParams layoutParams = new AbsListVIEw.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);notification_txt.setLayoutParams(layoutParams);all_adapter.addVIEw(notification_txt);

但是,如果您试图将整个视图简单地添加到您的mergeadapter中,则代替all_adapter.addVIEw(notification_txt);你可以说：all_adapter.addVIEw(notification);
