Question

We know that we can set a normal CheckBox by using the setChecked(boolean) method.
Is it possible to set the CheckBoxPreference through a method ?
Does there exist any method ?

Answer 1

How about… setChecked(boolean)? When you get a reference to your CheckBoxPreference (e.g. in your PreferenceActivity or PreferenceFragment) you should have no problem using this method.

I’m not sure what part you’re having trouble with, but the method call to CheckBoxPreference‘s setChecked(boolean) is no different from that of a regular CheckBox (as in: you just pass along a boolean value representing the ‘tick’):

CheckBoxPreference checkboxPref = new CheckBoxPreference(this);
// or:
CheckBoxPreference checkboxPref = (CheckBoxPreference) findPreference("checkbox_pref");
checkboxPref.setChecked(true);
