If you really insist on using a CheckBox where each element have 3 states then the following might work but I haven't tried it: - Make a class that extends the CheckBox class. - Add a variable : "checkstate" of type int or byte. The class should have a Boolean "isChecked" variable. - Override the onClick or onCheck method so that it change the checkstate variable between the 3 states instead of toggling the isChecked variable. - Upon display, check the "checkstate" and do some visual effect to show the 3rd state. - Finally, tell me if it works.
