Checkbox status issue

How we can know whether the check box is checked 开发者_JS百科or unchecked using java code

boolean checkBox.isChecked()

returns true if your 'checkBox' is checked, returns false otherwise.

If your checkbox is part of a preference menu, you can do:

boolean checked;
checked = preferences.getBoolean("checkBoxName", true);

Where "preferences" is your SharedPreferences object.

See this page for further reference on how to implement a preference menu.
