项目listView在删除项目后重叠。为什么?例如,在删除第一项之前和之后:
我正在使用方法删除元素:
public void updateData(List<ParseObject> data) {
mGroupList.clear();
mGroupList.addAll(data);
notifyDataSetChanged();
}
的ListView:
<ListView
android:id="@android:id/list"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:divider="@null"/>
适配器中的getView:
@Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder viewHolder;
if (convertView == null) {
viewHolder = new ViewHolder();
convertView = mLayoutInflater.inflate(R.layout.card_item, parent, false);
viewHolder.mCardViewNative = (CardViewNative) convertView.findViewById(R.id.card_view);
convertView.setTag(viewHolder);
} else {
viewHolder = (ViewHolder) convertView.getTag();
}
//code
viewHolder.mCardViewNative.setCard(card);
return convertView;
}
card_item.xml:
<it.gmariotti.cardslib.library.view.CardViewNative
android:background="@drawable/header_dark"
android:id="@+id/card_view"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
更新
如果不是每次都使用ViewHolder并充气视图,则不会重叠。但每次膨胀视图都不好。
@Override
public View getView(int position, View convertView, ViewGroup parent) {
convertView = mLayoutInflater.inflate(R.layout.card_item, parent, false);
CardViewNative cardViewNative = (CardViewNative) convertView.findViewById(R.id.card_view);
//code
cardViewNative.setCard(card);
return convertView;
}
答案 0 :(得分:0)
尝试
convertView = mLayoutInflater.inflate(R.layout.card_item, null);
而不是
convertView = mLayoutInflater.inflate(R.layout.card_item, parent, false);
它适用于我,使用ViewHolder作为静态类
