如何获取具有已知资源名称的资源 ID? [英] How to get a resource id with a known resource name?

问题描述

我想通过名称而不是 int id 访问像 String 或 Drawable 这样的资源.

我会使用哪种方法?

解决方案

它将类似于:

R.drawable.resourcename

确保您没有导入 Android.R 命名空间，因为它可能会混淆 Eclipse(如果您正在使用该命名空间).

如果这不起作用，您始终可以使用上下文的 getResources 方法...

Drawable resImg = this.context.getResources().getDrawable(R.drawable.resource);

其中 this.context 被初始化为 Activity、Service 或任何其他 Context 子类.>

更新:

如果是你想要的名字，Resources 类(由 getResources() 返回)有一个 getResourceName(int) 方法，并且getResourceTypeName(int)?

更新 2:

Resources 类有这个方法:

public int getIdentifier (String name, String defType, String defPackage)

返回指定资源名称的整数，类型 &包.

I want to access a resource like a String or a Drawable by its name and not its int id.

Which method would I use for this?

解决方案

It will be something like:

R.drawable.resourcename

Make sure you don't have the Android.R namespace imported as it can confuse Eclipse (if that's what you're using).

If that doesn't work, you can always use a context's getResources method ...

Drawable resImg = this.context.getResources().getDrawable(R.drawable.resource);

Where this.context is intialised as an Activity, Service or any other Context subclass.

Update:

If it's the name you want, the Resources class (returned by getResources()) has a getResourceName(int) method, and a getResourceTypeName(int)?

Update 2:

The Resources class has this method:

public int getIdentifier (String name, String defType, String defPackage) 

Which returns the integer of the specified resource name, type & package.
