尝试访问android项目资源时出现“无法查找符号”错误

Question

I'm learning how to program for Android atm. Following a tutorial for graphics , I've run into a problem; Attempting to access the image I've placed in the project resources renders the error "Cannot Find Symbol". Attempting to follow the advice NetBeans provided me with, I placed the image in the same package as the file I was writing, which rendered the same error telling me that there was nothing specifically where I'd place the file.

Since a picture speaks a thousand words, here's two pictures of what I'm talking about:

Had to stitch the images together because StackOverFlow wouldn't let me post images or more than 2 links.

Answer 1

你应该制作drawable文件夹而不是图像，并将图像放在drawable文件夹中并作为

R.drawable.your_icon_name

Answer 2

I was having the same problem at one point.

To fix it I did a clean and build on the project and it gave me a new error

res\\drawable\\sunBLU.png Invalid file name: must contain only [a-z0-9_.]

so I renamed my image with all lowercase letters, changed my code to match and did another clean and build. now my program works. Turns out it will only let you use lowercase letters in a image file name.

hope this helps other people
