A Preference

input.
It is a subclass of DialogPreference

This preference will store a string into the SharedPreferences.

Called when a Preference is being inflated and the default value attribute needs to be read. Since different Preference types have different value types, the subclass should get and return the default value which will be its value type.
For example, if the value type is String, the body of the method would
proxy to getString(int)
.

This function will never be called with a null state.
state | The saved state that had previously been returned by
onSaveInstanceState() . |

Hook allowing a Preference to generate a representation of its internal state that can later be used to create a new instance with that same state. This state should only contain information that is not persistent or can be reconstructed later.
Implement this to set the initial value of the Preference.
If restorePersistedValue is true, you should restore the
Preference value from the SharedPreferences
. If
restorePersistedValue is false, you should set the Preference
value to defaultValue that is given (and possibly store to SharedPreferences
if shouldPersist()
is true).
This may not always be called. One example is if it should not persist but there is no default value given.
restoreValue | True to restore the persisted value; false to use the given defaultValue. |
---|---|
defaultValue | The default value for this Preference. Only use this if restorePersistedValue is false. |
