如何按日期制作排序图库缩略图 [英] How to make sort gallery thumbnails image by date

问题描述

我正在开发一个Android应用程序。此应用程序从库中获取所有缩略图图像。我想按日期排序这些缩略图，但我不能这样做。

I am developing an android applicaiton. This application get all thumbnail images from gallery. I want to sort these thumbnails by date, but I can't do it.

请帮帮我。

获取所有图片

// Set up an array of the Thumbnail Image ID column we want
String[] columns = {MediaStore.Images.Media._ID};

String orderBy = MediaStore.Images.Thumbnails._ID + " DESC LIMIT 10";

// Create the cursor pointing to the SDCard

cursor = getActivity().managedQuery(MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI,
        columns, // Which columns to return
        null,       // Return all rows
        null,
        orderBy);

// Get the column index of the Thumbnails Image ID
columnIndex = cursor.getColumnIndexOrThrow(MediaStore.Images.Thumbnails._ID);

myGalleryImages = (GridView) view.findViewById(R.id.my_gallery);
myGalleryImages.setAdapter(new ImageAdapter(getActivity()));

设置图片

    // Move cursor to current position
    cursor.moveToPosition(position);
    // Get the current value for the requested column
    int imageID = cursor.getInt(columnIndex);
    // Set the content of the image based on the provided URI
    holder.image.setImageURI(Uri.withAppendedPath(MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI, "" + imageID));

推荐答案

更新列和 orderBy 像这样：

  String[] columns = {MediaStore.Images.Media._ID, MediaStore.Images.ImageColumns.DATE_TAKEN};

  String orderBy = MediaStore.Images.ImageColumns.DATE_TAKEN + " DESC"; 

并查看是否有帮助。

您还可以获取真实图像而不是缩略图，并使用图像加载库来处理正确的重新调整大小。在这种情况下，将缩略图引用替换为 ImageColumns

You could also fetch real images instead of thumbnails and use image loading library that will take care of proper re-sizing. In this case replace your Thumbnails references with ImageColumns
