Android——通过MediaStore查询图片

查询图片：

    private void loadImageList() {
        String[] columns = new String[]{
                MediaStore.Images.Media._ID, // 编号
                MediaStore.Images.Media.TITLE, // 标题
                MediaStore.Images.Media.SIZE, // 文件大小
                MediaStore.Images.Media.DATA, // 文件路径
        };
        Cursor cursor = getContentResolver().query(
                MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
                columns,
                "_size < 307200",
                null,
                "_size Desc"
        );
        int count = 0;
        if (cursor != null) {
            while (cursor.moveToNext() && count < 6) {
                ImageInfo image = new ImageInfo();
                image.id = cursor.getLong(cursor.getColumnIndex(MediaStore.Images.Media._ID));
                image.name = cursor.getString(cursor.getColumnIndex(MediaStore.Images.Media.TITLE));
                image.size = cursor.getLong(cursor.getColumnIndex(MediaStore.Images.Media.SIZE));
                image.path = cursor.getString(cursor.getColumnIndex(MediaStore.Images.Media.DATA));
                count++;
                mImageList.add(image);
            }
        }
    }
