R.layout.main的原始类型int没有字段输出

Question

I am new to Android, When I run the app it throws the following:

"The primitive type int of R.layout.main does not have a field out"

What am I doing wrong?

TIA Ricard

Answer 1

1) The 'R' file is generated from the assets in the res folder.

2) Check the file /res/layout/main.xml. The error message is stating there is not an 'out' field in this file. So your Java code must align with main.xml.

3) Check the 'R' file generated by the build process. Verify there is a 'main' in the 'layout' class.

Hints Eclipse does a good job of building the 'R' file. If it does not match the 'res' folder rebuild the project.

Do not edit the 'R' file by hand as it will be overwritten during the next build.
