                      "CheckBox1 is checked", Toast.LENGTH_SHORT).show();




With your number of posts you should know better then just drop code with no exact error

hi peter, log cat error actually is quite useless. i run it through the emulator the error message is quite general (not a specific error).

Just realised you are using switch statment and validating view ID. This is no longer safe. If you need to do that you should then doing it from if/else
