请任何人告诉我如何在列表视图和网格视图中按名称对图像进行排序。 我有Country_images和Country_names.Am按Country_name排序，但是，只能对country_names进行排序。请任何一个帮助如何按名称排序图像。

答案 0 :(得分：0)
您可以尝试使用此代码对country_Images：
TreeMap<String, Integer> names = new TreeMap<String, Integer>();
for (int i = 0; i< country_Images.length; i++) {
names.put(getResources().getResourceEntryName(country_Images[i]), country_Images[i]);
}
int i = 0;
int[] sortedCountryImages = new int[country_Images.length];
for (Entry<String, Integer> entry : names.entrySet()) {
sortedCountryImages[i] = entry.getValue();
i++;
}
country_Images = sortedCountryImages;
但请注意，排序后country_Images的顺序可能与country_Image_size
