通过id获取到命名

写道

Resources类中的这个方法可以通过id获取到命名，不过获取到的命名格式是 package:type/entry；
一般获得context后，用getResources().getResourceName(int id)， 返回字符串

/**
* Return the full name for a given resource identifier. This name is
* a single string of the form "package:type/entry".
*
* @param resid The resource identifier whose name is to be retrieved.
*
* @return A string holding the name of the resource.
*
* @throws NotFoundException Throws NotFoundException if the given ID does not exist.
*
* @see #getResourcePackageName
* @see #getResourceTypeName
* @see #getResourceEntryName
*/
public String getResourceName(@AnyRes int resid) throws NotFoundException {
return mResourcesImpl.getResourceName(resid);
}
