如何通过文件名查找/res/raw文件夹中文件的资源ID? [英] How to find resource id of a file located in /res/raw folder by its filename?

问题描述

我想通过文件名获取位于/res/raw文件夹中的文件的资源ID.我尝试了以下2种方法，但它们都将资源ID返回为0(零).

I want to get the resource id of the file located in /res/raw folder by filename. I have tried the following 2 methods but both of them return resource id as 0(zero).

方法1:

String filename = "abc.txt";
int id = getResources().getIdentifier(filename, "raw", getPackageName());

方法2:

String filename = "abc.txt";
String fullyQualifiedName = getPackageName() + ":raw/" + filename;
int id = getResources().getIdentifier(fullyQualifiedName, null, null);

如果这不是正确的方法，那么如何通过Android中raw文件夹中的文件名获取资源ID.

If this is not the correct way, then how do we get the resource id by filename located in raw folder in Android.

推荐答案

删除扩展名:

String filename = "abc";
int id = getResources().getIdentifier(filename, "raw", getPackageName());
