• Method Detail

  • setText

    public void setText(String text)

    Saves the text to the SharedPreferences.

    Parameters:

    text - The text to save

  • getText

    public String getText()

    Gets the text from the SharedPreferences.

    Returns:

    The current preference value.

  • onBindDialogView

    protected void onBindDialogView(View view)

    Description copied from class: DialogPreference
    Binds views in the content View of the dialog to data.

    Make sure to call through to the superclass implementation.

    Overrides:

    onBindDialogView in class DialogPreference

    Parameters:

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

  • onAddEditTextToDialogView

    protected void onAddEditTextToDialogView(View dialogView,
                                 EditText editText)

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

    Parameters:

    dialogView - The dialog view.

  • onDialogClosed

    protected void onDialogClosed(boolean positiveResult)

    Description copied from class: DialogPreference
    Called when the dialog is dismissed and should be used to save data to the SharedPreferences.

    Overrides:

    onDialogClosed in class DialogPreference

    Parameters:

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

  • onGetDefaultValue

    protected Object onGetDefaultValue(TypedArray a,
                           int index)

    Description copied from class: Preference
    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 TypedArray.getString(int).

    Overrides:

    onGetDefaultValue in class Preference

    Parameters:

    a - The set of attributes.

    index - The index of the default value attribute.

    Returns:

    The default value of this preference type.

  • onSetInitialValue

    protected void onSetInitialValue(boolean restoreValue,
                         Object defaultValue)

    Description copied from class: Preference
    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 Preference.shouldPersist() is true).

    This may not always be called. One example is if it should not persist but there is no default value given.

    Overrides:

    onSetInitialValue in class Preference

    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.

  • shouldDisableDependents

    public boolean shouldDisableDependents()

    Description copied from class: Preference
    Checks whether this preference's dependents should currently be disabled.

    Overrides:

    shouldDisableDependents in class Preference

    Returns:

    True if the dependents should be disabled, otherwise false.

  • getEditText

    public EditText getEditText()

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

    Returns:

    The EditText widget that will be shown in the dialog.

  • needInputMethod

    protected boolean needInputMethod()

    Description copied from class: DialogPreference
    Returns whether the preference needs to display a soft input method when the dialog is displayed. Default is false. Subclasses should override this method if they need the soft input method brought up automatically.

    Overrides:

    needInputMethod in class DialogPreference

  • onSaveInstanceState

    protected Parcelable onSaveInstanceState()

    Description copied from class: Preference
    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.

    Overrides:

    onSaveInstanceState in class DialogPreference

    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.

    See Also:

    Preference.onRestoreInstanceState(android.os.Parcelable), Preference.saveHierarchyState(android.os.Bundle)

  • onRestoreInstanceState

    protected void onRestoreInstanceState(Parcelable state)

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

    Overrides:

    onRestoreInstanceState in class DialogPreference

    Parameters:

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

    See Also:

    Preference.onSaveInstanceState(), Preference.restoreHierarchyState(android.os.Bundle)
