android:visibility attribute in preferences xml not working? (Android 2.3)
android:visibility is used to show and hide Views but it's not valid for a Preference. The documentation for Preference lists the available XML attributes, but none of them are what you want.
It is, however, possible to add and remove preferences from a PreferenceScreen programatically.
For AndroidX users, add this directly to your preference XML
app:isPreferenceVisible="false"
You have to use setVisible method to change the visibility.
First, initialize the checkbox preference.
CheckBoxPreference showSigPreference = (CheckBoxPreference) findPreference("show_sig");then
// Show the check box preferenceshowSigPreference.setVisible(true);// Hide the check box preferenceshowSigPreference.setVisible(false);
