I want to save boolean values and then compare them in an if-else block.
My current logic is:
boolean locked = true;
if (locked == true) {
/* SETBoolean TO FALSE */
} else {
Intent newActivity4 = new Intent(parent.getContext(), Tag1.class);
startActivity(newActivity4);
}
How do I save the boolean variable which has been set to false?
SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences();
Boolean statusLocked = prefs.edit().putBoolean("locked", true).commit();
if you dont care about the return value (status) then you should use .apply() which is faster because its asynchronous.
prefs.edit().putBoolean("locked", true).apply();
to get them back use
Boolean yourLocked = prefs.getBoolean("locked", false);
while false is the default value when it fails or is not set
In your code it would look like this:
boolean locked = true;
SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences();
if (locked) {
//maybe you want to check it by getting the sharedpreferences. Use this instead if (locked)
// if (prefs.getBoolean("locked", locked) {
prefs.edit().putBoolean("locked", true).commit();
} else {
startActivity(new Intent(parent.getContext(), Tag1.class));
}
