我有一个web视图的活动，并希望缓存内容。在默认情况下，它不显示为使用缓存

I have an activity with a WebView and want to cache content. By default, it does not appear to be using the cache.

Android的 WebSettings 有几个不同的缓存相关的常量。

Android's WebSettings has several different cache-related constants.

当我设置缓存模式，以LOAD_CACHE_ELSE_NETWORK，它似乎使用缓存。不过，我不希望使用过期的缓存内容。

When I set the cache mode to 'LOAD_CACHE_ELSE_NETWORK', it appears to use the cache. However, I don't want to use expired cache content.

这让我使用：

但文件并没有细说什么是正常和默认的意思。

But the documentation does not elaborate on what "normal" and "default" mean.

如何在这两种模式有什么不同？

How do these two modes differ?

推荐答案

我同意，人们会想到NORMAL_MODE是默认模式，但很明显这是两个不同的值。

I agree, one would expect that NORMAL_MODE is the default mode, but clearly this is two different values.

我想回答问题2（LOAD_NORMAL）中的的WebSettings.setCacheMode（INT模式）文档

I think answer to question 2. (LOAD_NORMAL) is answered in the documentation for WebSettings.setCacheMode(int mode)

对于一个正常的页面加载，缓存进行检查，并根据需要的内容重新验证。导航时回来，内容不重新验证，而不是内容只是从缓存中拉出。此功能允许客户端覆盖此行为。

For a normal page load, the cache is checked and content is re-validated as needed. When navigating back, content is not revalidated, instead the content is just pulled from the cache. This function allows the client to override this behavior.
