Based on the following code, can you tell me how to refresh the PreferenceActivity window to show changes in the settings immediately? For example: the user taps the master chime toggle checkbox to true (ticked), I would like the user to immediately see the other settings such as the ChimeOn15Past checkbox also be be true (ticked)
SharedPreferences.Editor prefEditor = clockSettings.edit(); // Allow the settings to be changed.
if (booleanMasterChimeToggle == true) {
prefEditor.putBoolean("ChimeOnTheHour", true);
prefEditor.putBoolean("ChimeOn15Past", true);
prefEditor.putBoolean("ChimeOn30Past", true);
prefEditor.putBoolean("ChimeOn45Past", true);
strNotifyMessage = "Full chiming has now been set.";
} else {
prefEditor.putBoolean("ChimeOnTheHour", false);
prefEditor.putBoolean("ChimeOn15Past", false);
prefEditor.putBoolean("ChimeOn30Past", false);
prefEditor.putBoolean("ChimeOn45Past", false);
strNotifyMessage = "Full chiming has now been disabled.";
}
Instead of
finish();
startActivity(getIntent());
I prefer the following code :
setPreferenceScreen(null);
addPreferencesFromResource(R.xml.preferences);
This will reset the display as well but without the whole finish procedure and its consequences.
Plus this code works well with PreferenceActivity
and PreferenceFragment
.
This is interesting if you would like to change dynamically the locale value for example. In this case, working with the manager is not enough because you want a full reload of titles and values.
EDIT: setPreferenceScreen
is deprecated in PreferenceActivity
(still working) but is not in PreferenceFragment
