问题描述
我创建的项目包含删除按钮的适配器。当用户点击按钮的项目应该被删除。
如果我用这个code:
I created an adapter with items that contains remove buttons. When the user click the button the item should be removed. If I use this code:
list.remove(item);
notifyDataSetChanged();
它成功。但是,当我添加了动画应用程序崩溃与此异常:
it succeeds. But when I added animation the application crashes with this exception:

适配器来源:
public class SearchHistoryAdapter extends BaseAdapter {
private List<SearchItem> list;
public SearchHistoryAdapter( List<SearchItem> list ){
this.list = list;
}
@Override
public int getCount(){
return list.size();
}
@Override
public Object getItem( final int i ){
return list.get( i );
}
@Override
public long getItemId( final int i ){
return 0;
}
@Override
public View getView( final int i, final View convertView, final ViewGroup parent ){
SearchItem item = list.get( i );
View row = convertView;
final ContentHolder holder;
if( convertView == null ){
holder = new ContentHolder();
row = LayoutInflater.from( parent.getContext() ).inflate( R.layout.item_search_history, null );
holder.remove = (ImageButton)row.findViewById( R.id.ib_search_history_remove );
…
holder.remove.setFocusable( false );
holder.remove.setOnClickListener( removeClick );
row.setTag( holder );
} else {
holder = (ContentHolder)row.getTag();
}
holder.remove.setTag( item );
…
return row;
}
private View.OnClickListener removeClick = new View.OnClickListener() {
@Override
public void onClick( final View view ){
final SearchItem item = (SearchItem)view.getTag();
final View itemView = (View)view.getParent().getParent();
Animation animation = AnimationUtils.loadAnimation( view.getContext(), R.anim.attributes_disappear );
animation.setAnimationListener( new Animation.AnimationListener() {
@Override
public void onAnimationStart( final Animation animation ){ }
@Override
public void onAnimationEnd( final Animation animation ){
list.remove( item );
notifyDataSetChanged();
}
@Override
public void onAnimationRepeat( final Animation animation ){ }
} );
itemView.startAnimation( animation );
}
};
static class ContentHolder {
TextView name;
TextView category;
TextView description;
TextView number;
ImageButton remove;
}
public static class SearchItem {
...
}
}
ListView控件同时具有页眉和页脚的看法。
The ListView has both header and footer views.
推荐答案
尝试更换这行:
holder.remove.setTag( item );
这一点:
holder.remove.setTag(i);
您也把这个行:
holder.remove.setOnClickListener( removeClick ); outside if else code
