Question

滑动时候产生残影

Adapter 代码

public class AlphaSideBarAdapter extends BaseAdapter implements SectionIndexer {

private    List<Brand.BrandEntity> brandEntities;

private LayoutInflater  inflate;

public AlphaSideBarAdapter(Context  context  , List<Brand.BrandEntity>  brandEntities) {
    inflate=LayoutInflater.from(context);
    this.brandEntities=brandEntities;
}
public     void     setData( List<Brand.BrandEntity>  brandEntities)
{
     this.brandEntities.clear();
     this.brandEntities.addAll(brandEntities);
     notifyDataSetChanged();
}
@Override
public int getCount() {
    return brandEntities.size();
}
@Override
public Object getItem(int position) {
    return brandEntities.get(position);
}

@Override
public long getItemId(int position) {
    return position;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    ViewItem item = new ViewItem();

    if (convertView == null) {
        convertView = inflate.inflate(R.layout.list_item_brand_sidebar, parent, false);
        item.alpha = (TextView) convertView.findViewById(R.id.list_item_brand_sidebar_alpha);
        item.name = (TextView) convertView.findViewById(R.id.list_item_brand_sidebar_name);
        convertView.setTag(item);
    } else {
        item = (ViewItem) convertView.getTag();
    }
    //根据position获取分类的首字母的char ascii值
    int section = getSectionForPosition(position);
    //如果当前位置等于该分类首字母的Char的位置 ，则认为是第一次出现
    if (position == getPositionForSection(section)) {
        item.alpha.setVisibility(View.VISIBLE);
        item.alpha.setText(brandEntities.get(position).getSortLetters().toUpperCase());
    } else {
        item.alpha.setVisibility(View.GONE);
    }
    final Brand.BrandEntity brandEntity = (Brand.BrandEntity) getItem(position);
    item.name.setText(brandEntity.getName());
    return convertView;
}
@Override
public Object[] getSections() {
    return null;
}
@Override
public int getPositionForSection(int section) {
    for (int i = 0; i < getCount(); i++) {
        char first = brandEntities.get(i).getSortLetters().charAt(0);
        if (first == section) {
            return i;
        }
    }
    return -1;
}
@Override
public int getSectionForPosition(int position) {
    return brandEntities.get(position).getSortLetters().charAt(0);
}
class ViewItem {
    TextView alpha;
    TextView name;
}

}

布局代码：
<?xml version="1.0" encoding="utf-8"?>
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="48dp"
    android:gravity="center"
    android:background="@color/topbar_bg">

        android:scrollbars="none"
        />

    <TextView

        android:layout_height="match_parent"
        android:layout_gravity="right|center_vertical"
        />
</FrameLayout>
