批量获取Android上的许多位图资源 [英] Batch getting many bitmap resources on Android

问题描述

我有很长的系列显卡 - icon1_0.png，icon1_1.png，icon1_2.png ...，icon12_0.png，icon12_1.png，icon12_2.png - 我想他们包我Android应用程序。理想情况下，我想我应该能够加载它们的资源，但资源的ID被设置为java的标识符。当然，java的标识符不能在运行时被组装。我要问R.drawable.icon12_00所以我不能建立一个循环

I have a long series of graphics -- icon1_0.png, icon1_1.png, icon1_2.png..., icon12_0.png, icon12_1.png, icon12_2.png -- and I'd like to package them with my android application. Ideally I think I should be able to load them as resources but the resource id's are set up as java identifiers. Of course, java identifiers can't be assembled at runtime. I have to ask for R.drawable.icon12_00 so I cannot set up a loop

for(int icon=0;icon<12;icon++)
 for(int frame=0;frame<3;frame++)
  //syntax error obviously
  BitmapFactory.decodeResource(getResources(), R.drawable."icon" + icon + "_" + frame + ".png");

那么，有没有办法用自己的名字来获得资源呢？更重要的是，是否有资源系统外的正规途径打包的数据文件到一个Android应用程序包，这样我可以在他们获得？

So is there any way to get resources by their names? Better yet, is there a canonical way outside the resource system to pack data files into an android application package so that I can get at them?

我在想反映，但似乎并不像正确的解决方案给我。

I'm thinking about reflection but that doesn't seem like the right solution to me.

推荐答案

使用 getResources（）。则getIdentifier（）从上下文（例如，活动），但请缓存结果，如果你会用它不止一次。 则getIdentifier（）是在<一个实施href="http://developer.android.com/reference/android/content/res/Resources.html"><$c$c>Resources.

Use getResources().getIdentifier() from your Context (e.g., Activity), but please cache the result if you will use it more than once. getIdentifier() is implemented on Resources.
