问题描述

Lets say I have an xml file called test1.xml in String xmlFile = "test1.xml" format. How can I get the R.id.test1 value of it?

推荐答案

我想你想中的则getIdentifier（字符串名称，字符串DEFTYPE，字符串defPackage）方法资源类。这里是<一个href=\"http://developer.android.com/reference/android/content/res/Resources.html#getIdentifier%28java.lang.String,%20java.lang.String,%20java.lang.String%29\"相对=nofollow>文档。

I think you want the getIdentifier (String name, String defType, String defPackage) method within the Resources class. Here is the documentation.

但是，这种做法是相当缓慢的，注意从文档如下：

However this approach is quite slow, note the following from the docs:

请注意：使用此功能被劝阻。它是更有效的由标识符不是名称检索资源。

Note: use of this function is discouraged. It is much more efficient to retrieve resources by identifier than by name.

下面是另外一个类似的问题：<一href=\"http://stackoverflow.com/questions/3476430/get-resource-id-by-passing-name-as-a-parameter-in-android\">get在Android的传递名作为参数的资源ID

Here is another similar question: get resource id by passing name as a parameter in android
