Menu
I have preferences page. It has field 'Show info screen' (as checkbox).
I have also info page which also should have checkbox 'Show me again'.
As I've understand, I can get value from preferences page via PreferencesManager.getDefaultPreferences(context) ...
But how I should set preferences value for the checkbox on info page?
I tried to use context.getSharedPreferences(PREF_NAME, 0).edit(), to set value but it doesn't correlate with PreferencesManager's corresponding value.
What should I do??? F1

Shared Preferences allow you to save and retrieve data in the form of key,value pair. In order to use shared preferences, you have to call a method getSharedPreferences() that returns a SharedPreference instance pointing to the file that contains the values of preferences.
getBoolean(String key, boolean defValue): This method is used to retrieve a boolean value from the preferences. getFloat(String key, float defValue): This method is used to retrieve a float value from the preferences. getInt(String key, int defValue): This method is used to retrieve an int value from the preferences.
Public methods. Commit your preferences changes back from this Editor to the SharedPreferences object it is editing. Mark in the editor to remove all values from the preferences. Commit your preferences changes back from this Editor to the SharedPreferences object it is editing.
If you have a relatively small collection of key-values that you'd like to save, you should use the SharedPreferences APIs. A SharedPreferences object points to a file containing key-value pairs and provides simple methods to read and write them.
It depends on whether you are after one set of preferences for your application, or one set per activity.
I've used code like this:
SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(getContext()); Editor editor = prefs.edit(); editor.putBoolean(PREF_NAME, false); editor.commit(); and
SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(getContext()); if (prefs.getBoolean(PREF_NAME, true)) { // etc } If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
