加载一个Android资源到web视图 [英] Loading an Android resource into a webview

问题描述

我有一个Android应用程序，显示一本漫画书。为了使用内置变焦控制，我加载图片中，像这样一个web视图：

I have an Android app that displays a comic book. To make use of the built-in zoom controls, I am loading the pictures in a webview like so:

webView.loadUrl("file:///android_asset/page1.jpg");

这是工作得很好，但是，由于图像是在资产的文件夹，它们不是COM pressed这使我的apk巨大的。我想知道如何引用资源文件（从RES /绘制文件夹）与文件路径像我一样以上的资产。有谁知道这条道路是什么样子？我试着像文件：///res/drawable/pagetitle.jpg，但没有成功。感谢您的帮助。

This is working just fine, however, since the images are in the assets folder, they are not being compressed which makes my .apk enormous. I was wondering how to reference resource files (from the res/drawable folder) with a file path like I did above with the assets. Does anyone know what that path would look like? I've tried things like "file:///res/drawable/pagetitle.jpg" with no success. Thanks for the help.

更新：我发现这一点。文件：///android_res/drawable/page1.jpg是，我一直在寻找的路径

Update: I found that "file:///android_res/drawable/page1.jpg" was the path that I was looking for.

使用资源ID，格式是：

Using the resource id, the format is:

"android.resource://[package]/[res id]"

Uri path = Uri.parse("android.resource://com.androidbook.samplevideo/" + R.raw.myvideo);

，或使用资源子目录（型）和资源名称（文件名不带扩展名），格式为：

or, using the resource subdirectory (type) and resource name (filename without extension), the format is:

"android.resource://[package]/[res type]/[res name]"

Uri path = Uri.parse("android.resource://com.androidbook.samplevideo/raw/myvideo");
