R.java file which can not be automatically generated address the

 
public static final class id {
public static final int action_settings = 0x7f080008; 
public static final int button = 0x7f080007; 
public static final int cb = 0x7f080006; 
public static final int radio2 = 0x7f080005; 
public static final int radioGroup1 = 0x7f080002; 
public static final int rb_ = 0x7f080004; 
public static final int rb_private = 0x7f080003; 
public static final int tvPassword = 0x7f080001; 
public static final int tvUser = 0x7f080000; 

The above is R.java code inside.
I have a few RaidoButton (exclude xml file inside the code errors), obviously there id, but not here to generate.

There is a situation that could not be automatically generated R.java, then the program inside because they can not generate R.java stuff and error, but because there is an error and cause R.java not automatically generate , so a vicious cycle, I encountered such a situation, the last being given the first piece The code to note away, then R.java automatically generated.

Yes, because I can not find things inside R.java and error.
Then something inside R.java not automatically generated.
Could I get into this cycle of death yet.
But thank you for giving me tips, I try. Temporarily comment period "can not find things in R.java and error," the statement.
