                EditText editText)

Adds the EditText widget of this preference to the dialog's view.

Parameters
dialogView View: The dialog view.
editText EditText

onBindDialogView

Added in API level 1
void onBindDialogView (View view)

Binds views in the content View of the dialog to data.

Make sure to call through to the superclass implementation.

Parameters
view View: The content View of the dialog, if it is custom.

onDialogClosed

Added in API level 1
void onDialogClosed (boolean positiveResult)

Called when the dialog is dismissed and should be used to save data to the SharedPreferences.

Parameters
positiveResult boolean: Whether the positive button was clicked (true), or the negative button was clicked or the dialog was canceled (false).

onGetDefaultValue

Added in API level 1
Object onGetDefaultValue (TypedArray a, 
                int index)

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).

Parameters
a TypedArray: The set of attributes.
index int: The index of the default value attribute.
Returns
Object The default value of this preference type.

onRestoreInstanceState

Added in API level 1
void onRestoreInstanceState (Parcelable state)

Hook allowing a Preference to re-apply a representation of its internal state that had previously been generated by onSaveInstanceState(). This function will never be called with a null state.

Parameters
state Parcelable: The saved state that had previously been returned by onSaveInstanceState().

onSaveInstanceState

Added in API level 1
Parcelable 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.

Returns
Parcelable A Parcelable object containing the current dynamic state of this Preference, or null if there is nothing interesting to save. The default implementation returns null.

onSetInitialValue

Added in API level 1
void onSetInitialValue (boolean restoreValue, 
                Object defaultValue)

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.

Parameters
restoreValue boolean: True to restore the persisted value; false to use the given defaultValue.
defaultValue Object: The default value for this Preference. Only use this if restorePersistedValue is false.
