是否可以更改毕加索用于图像的缓存大小? [英] Is it possible to change the size of the cache Picasso uses for images?

问题描述

我正在使用Picasso从URL(http://)加载图像. 有时，当我尝试使用Picasso的fetch()方法预加载"图像时，该图像不会被缓存.我猜是因为它太大了.

I'm loading images from URLs (http://) with Picasso. Sometimes when i try to "preload" an image using Picasso's fetch() method, the image doesn't get cached. I guess it's because it's size is too big.

阅读这个问题的答案，但setCache()似乎没有为我所认可，我什至没有在毕加索文档中找到它.

Read the answer for this question, but setCache() doesn't seem to be recognized for me, i don't even find it in the Picasso documentation.

有什么方法可以更改毕加索用于位图的缓存大小吗?

Is there any way to change the cache size Picasso uses for bitmaps?

推荐答案

您可以这样做:

int maxSize = MAX_CACHE_SIZE;
Picasso picasso = new Picasso.Builder(context)
                              .memoryCache(new LruCache(maxSize))
                              .build();

Picasso使用 Cache 接口类型来管理缓存.它们提供了默认实现 LruCache ，具有构造函数，该结构接受最大大小(以字节为单位)作为参数.

Picasso uses a Cache interface type to manage the cache. They provide the default implementation, LruCache, which has a constructor that accepts the max size in bytes as an argument.

似乎其他答案使用了错误的功能.应该是memoryCache，而不是setCache.

Seems like the other answer uses the wrong function. It should be memoryCache, not setCache.
