BitmapFactory.decodeFile 可以处理 .ICO(Windows 图标)文件吗? [英] Can BitmapFactory.decodeFile handle .ICO (Windows icons) files?

问题描述

我正在开发 Android.尝试显示收藏夹图标"(又名快捷方式图标")或网页.

I am working on Android. Trying to display the "favicon" (aka "shortcut icon") or web pages.

所以我已经有了从任何网站获取此图标 URL 的代码，并将其下载到我的 Android 上.

So I already have the code to get the URL of this icon from any website, and download it onto my Android.

现在我试图用它制作位图，但结果总是为空.

Now I am trying to make a Bitmap out of it, but always get null as a result.

代码:

String src = String.format("file:///data/data/com.intuitiveui.android/files/%s",prefName);
// prefName is "facebook.ico", and I do see tht file in my DDMS file browser. It's
// a valid icon file.

Bitmap res = BitmapFactory.decodeFile(src);
// This returns null

TIA

推荐答案

这里是 支持的 Android 媒体格式.ICO 不在其中.不过，您或许可以找到基于 Java 的 ICO 解码器.

Here is a list of the supported Android media formats. ICO is not among them. You might be able to find a Java-based ICO decoder, though.
