Question

我的ListView使用HorizontalListView滚动速度很慢

我试图将HorizontalListView作为其他ListView中的页脚实现

或作为标题和它的工作，但它太慢，它不能正常工作。

所以这是我的客户适配器

public class HorizntallMediaList extends
    ArrayAdapter<ItemsMediaSuggestion> {
String ImageURL;
Context context;
int table = 0;
List<ItemsMediaSuggestion> objects;

ItemsMediaSuggestion related;

public HorizntallMediaList(Context context, int textViewResourceId,
        List<ItemsMediaSuggestion> objects,
        int table) {
    super(context, textViewResourceId, objects);

    this.context = context;
    this.objects = objects;
    this.table = table;
}

viewHolder holder = new viewHolder();

private class viewHolder {

    private RelativeLayout relativeLayout;
    private ImageView userImage, addImage;
    private TextView userName;

}

@Override
public long getItemId(int position) {

    return super.getItemId(position);
}

@Override
public int getCount() {

    return super.getCount();
}

@Override
public ItemsMediaSuggestion getItem(int position) {

    return super.getItem(position);
}


@Override
public View getView(final int position, View convertView, ViewGroup parent) {

    try{
        related = getItem(position);
    } catch (IndexOutOfBoundsException e) {

    }

    LayoutInflater inflater = (LayoutInflater) context
            .getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
    if (convertView == null) {
        convertView = inflater.inflate(R.layout.items_wall_horizntal,
                parent, false);

        holder = new viewHolder();

        holder.relativeLayout = (RelativeLayout) convertView
                .findViewById(R.id.horRelative);
        holder.userImage = (ImageView) convertView
                .findViewById(R.id.HorUserImage);

        holder.userName = (TextView) convertView.findViewById(R.id.HorName);
        holder.addImage = (ImageView) convertView.findViewById(R.id.HorAdd);
        holder.addImage.setVisibility(View.GONE);
        convertView.setTag(holder);

    } else {

        holder = (viewHolder) convertView.getTag();
    }


    holder.relativeLayout
            .setBackgroundColor(GlobalConstants.ColorPicker_int);

    if (table == 5) {
         ImageURL    = GlobalConstants.server_file
                + table
                + "/m/"
                + related.getStorage()
                + "."
                + related.getStorageRand() + ".jpg";

        holder.userName.setText(PublicMethods.readable(related
                .getDescribtion()));


    } else if (table == 6) {

        if (related.getStorage().equals("0")) {
            holder.userName.setText(PublicMethods.readable(related
                    .getTitle()));

             ImageURL = "https://img.youtube.com/vi/"
                    + related.getStorageRand() + "/1" + ".jpg";


        } else {
             ImageURL = GlobalConstants.server_file
                    + table
                    + "/m/"
                    + related.getStorage()
                    + "."
                    + related.getStorageRand() + ".jpg";

            holder.userName.setText(PublicMethods.readable(related
                    .getTitle()));



        }
    } else {

         ImageURL = GlobalConstants.server_file
                + 5
                + "/m/"
                + related.getStorage()
                + "."
                + related.getStorageRand() + ".jpg";

        holder.userName.setText(PublicMethods.readable(related.getTitle()));


    }
    Picasso.with(context).load(ImageURL).fit().into(holder.userImage);

    return convertView;
}

}

Answer 1

试试这个：

    <ListView
    ...
    android:smoothScrollbar="true"/>

ListView滚动如此之慢
