合并适配器标头崩溃
作者:互联网
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: main
08-06 11:54:15.558: E/AndroidRuntime(20408): java.lang.ClassCastException: android.widget.LinearLayout$LayoutParams cannot be cast to android.widget.AbsListView$LayoutParams

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);
