推荐答案
这是不可能直接砸的东西进入的WebView缓存。这不会需要preloading在关闭屏幕的WebView的唯一方法（这是完全可能，顺便说一句）将是你自己下载图像，并利用它们服务回的WebView <一个href=\"http://developer.android.com/reference/android/webkit/WebViewClient.html#shouldInterceptRequest%28android.webkit.WebView,%20java.lang.String%29\"相对=nofollow> shouldInterceptRequest 。
It's not possible to drop things into the WebView's cache directly. The only way that would not require preloading in an "off-screen" WebView (which is totally possible, btw.) would be to download the images yourself and serve them back to the WebView using shouldInterceptRequest.
我会建议谨慎使用基于shouldInterceptRequest的方法虽然。这很容易损害性能使用shouldInterceptRequest时（在这里看到 ）。另外，你需要从你的缓存删除一些无用的图像的照顾。
I would recommend caution with the shouldInterceptRequest-based approach though. It's easy to hurt performance when using shouldInterceptRequest (see here). Also, you need to take care of removing stale images from your 'cache'.
