Question

我有以下代码：

ArrayList<FileInfo> mDataSource;
DateFormat mDateFormat = DateFormat.getDateTimeInstance(DateFormat.SHORT,
        DateFormat.SHORT, Locale.getDefault()); // one instance, no needed to be recreated each time

...

public void addFiles(String path) {
    if (!mDataSource.isEmpty())
        mDataSource.clear();

    boolean showhidden = Settings.showHiddenFiles();

    final File file = new File(path);

    // based on source from SimpleUtils
    if (file.exists() && file.canRead()) {
        File[] list = file.listFile(); //get list of File object, rather than list of String

        // add files/folder to ArrayList depending on hidden status
        for (File aList : list) {
            String fileName = aList.getName();
            boolean isFile = aList.isFile();
            boolean isDir = aList.isDirectory();
            if ((isFile || isDir) && (showhidden || (fileName.charAt(0) != '.'))) {
                FileInfo fileInfo = new FileInfo();
                fileInfo.mName = fileName;
                fileInfo.mIsFile = isFile;
                if (isFile) {
                    fileInfo.mLength = aList.length();
                } else {
                    fileInfo.mLength = aList.list().length;
                }
                fileInfo.mLastModified = mDateFormat.format(aList.lastModified());
                IconPreview.getFileIcon(aList, fileInfo.mIcon);
                mDataSource.add(fileInfo);
            }
        }
    } else if (Settings.rootAccess()) {
        //TODO make the same for root access
    } else {
        Toast.makeText(mContext, mContext.getString(R.string.cantreadfolder), Toast.LENGTH_SHORT).show();
    }
    // sort files with a comparator if not empty
    if (!mDataSource.isEmpty()) {
        Collections.sort(mDataSource, new Comparator<FileInfo>() {
            @Override
            public int compare(FileInfo lhs, FileInfo rhs) {
                return lhs.mName.toLowerCase().compareTo(rhs.mName.toLowerCase());
            }
        });
    }

    notifyDataSetChanged();
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    final ViewHolder mViewHolder;
    int num_items = 0;
    final FileInfo file = mDataSource.get(position);
    DateFormat df = DateFormat.getDateTimeInstance(DateFormat.SHORT,
            DateFormat.SHORT, Locale.getDefault());

    if (convertView == null) {
        convertView = mInflater.inflate(R.layout.item_browserlist, parent,
                false);
        mViewHolder = new ViewHolder(convertView);
        convertView.setTag(mViewHolder);
    } else {
        mViewHolder = (ViewHolder) convertView.getTag();
    }

    if (Settings.getListAppearance() > 0) {
        mViewHolder.dateview.setVisibility(TextView.VISIBLE);
    } else {
        mViewHolder.dateview.setVisibility(TextView.GONE);
    }

    if (Settings.getListAppearance() > 0) {
        if (file.mIsFile)) {
            // Shows the size of File
            mViewHolder.bottomView.setText(SimpleUtils.formatCalculatedSize(file.mLength));
        } else {
            // show the number of files in Folder
            mViewHolder.bottomView.setText(file.mLength
                    + mResources.getString(R.string.files));
        }
    }

    mViewHolder.topView.setText(file.mName);
    mViewHolder.dateview.setText(file.mLastModified);

    return convertView;
}

Answer 1

首先创建一个文件并将其保存在控制器文件夹中，其名称如say.php（如果你使用CI 3.X，它应该是Image.php，否则它将不起作用。）。然后在routes.php文件中将其设置为默认控制器（您可以在config文件夹中找到它）。控制器文件的代码应该是这样的：

<?php
//if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Image extends CI_Controller 
{
    function __construct()
    {
        parent::__construct();
    }

    public function index()
    {
       $this->load->view('image'); // name of your html file whose code you have written above.
    }
}
?>

并更改此http://yousounds.com/admin/img/gallery/original/17148640751407882364.jpg 进入

<?php echo base_url(); ?>img/gallery/original/17148640751407882364.jpg

Answer 2

如果您想要CI中的图像路径，请使用

src="<?php echo base_url()?>admin/img/gallery/original/8962835311407882364.jpg"

所以你的最终代码将是

<img alt="bannerimage" class="slider-image" src="<?php echo base_url()?>admin/img/gallery/original/8962835311407882364.jpg">

然后文件结构将（根据您的src）

- admin
 - img
  - gallery
    - original
      - 8962835311407882364.jpg

注意：要使用base_url()，请在config/config.php

中执行此配置

$config['base_url'] = '';
$config['index_page'] = '';
