Question

嘿我正在尝试查看网格视图中id小于100的特定项目。这是我的适配器类，但由于某种原因它无法工作并显示所有项目。登录身份证，他们都很好。

public View getView(int position, View convertView, ViewGroup parent) {
    PreviousViewHolder holder = null;
    ServerFeed previousDayRank = getItem(position);

    LayoutInflater layoutInflater = (LayoutInflater) context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
    if (convertView == null) {
        if (previousDayRank.getId() < 100) {
            convertView = layoutInflater.inflate(R.layout.popular_discover_list_item, null);
            holder = new PreviousViewHolder(convertView);
            convertView.setTag(holder);
        } else {
            convertView = layoutInflater.inflate(R.layout.null_item, null);
            holder = new PreviousViewHolder(convertView);
            convertView.setTag(holder);
        }

    } else {

        holder = (PreviousViewHolder) convertView.getTag();
        holder.setImageUrl(getContext(), previousDayRank.getName(), previousDayRank.getId());
    }
    return convertView;

}

像这样更改你的getView方法

    public View getView(int position, View convertView, ViewGroup parent)                {
        PreviousViewHolder holder = null;
        ServerFeed previousDayRank = getItem(position);

        LayoutInflater layoutInflater = (LayoutInflater) context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
        if (convertView == null) {           
 convertView = layoutInflater.inflate(R.layout.popular_discover_list_item, null);
                holder = new PreviousViewHolder(convertView);
                convertView.setTag(holder);
            } else {

                holder = (PreviousViewHolder)convertView.getTag();

            }

        if(previousDayRank.getId() < 100){
        holder.setImageUrl(getContext(), previousDayRank.getName(), previousDayRank.getId());}
       return convertView;
    }

只需在传递给addapter之前过滤您的数据。就像那样：

for(ServerFeed item : mServerFeeds){if(item.getId() > 100) mServerFeeds.remove(item);}

Answer 3

在您的代码中调用此方法 -

$opts = array(
// 'debug' => true,
'roots' => array(
    array(
        'driver'        => 'FTP', 
        'path'          => 'here i give path of folder', 
        'accessControl' => 'access'  ,
          'tmpPath' => '../files/ftp',// disable and hide dot starting files (OPTIONAL)
                'defaults' => array('read' => true, 'write' => true),
                'disabled' => array('rename', 'rm' , 'copy' ,'cut','paste')
    )
)
  );

仅查看网格视图中的特定项目
