Public Methods

public EditText getEditText ()

Since: API Level 1

Returns the EditText widget that will be shown in the dialog.

Returns

The EditText widget that will be shown in the dialog.

public String getText ()

Since: API Level 1

Gets the text from the SharedPreferences.

Returns

The current preference value.

public void setText (String text)

Since: API Level 1

Saves the text to the SharedPreferences.

Parameters

text	The text to save

public boolean shouldDisableDependents ()

Since: API Level 1

Checks whether this preference's dependents should currently be disabled.

Returns

True if the dependents should be disabled, otherwise false.

Protected Methods

protected void onAddEditTextToDialogView (View dialogView, EditText editText)

Since: API Level 1

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

Parameters

dialogView	The dialog view.

protected void onBindDialogView (View view)

Since: API Level 1

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

Make sure to call through to the superclass implementation.

Parameters

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

protected void onDialogClosed (boolean positiveResult)

Since: API Level 1

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

Parameters

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

protected Object onGetDefaultValue (TypedArray a, int index)

Since: API Level 1

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	The set of attributes.
index	The index of the default value attribute.

Returns

The default value of this preference type.

protected void onRestoreInstanceState (Parcelable state)

Since: API Level 1

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	The saved state that had previously been returned by `onSaveInstanceState()`.

protected Parcelable onSaveInstanceState ()

Since: API Level 1

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

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.

protected void onSetInitialValue (boolean restoreValue, Object defaultValue)

Since: API Level 1

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	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.
