Public methods

getText

public @Nullable String getText()

Gets the text from the current data storage.

Returns
`@Nullable String`	The current preference value

setOnBindEditTextListener

Added in 1.1.0

public void setOnBindEditTextListener(
    @Nullable EditTextPreference.OnBindEditTextListener onBindEditTextListener
)

Set an OnBindEditTextListener that will be invoked when the corresponding dialog view for this preference is bound. Set null to remove the existing OnBindEditTextListener.

Parameters
`@Nullable EditTextPreference.OnBindEditTextListener onBindEditTextListener`	The `OnBindEditTextListener` that will be invoked when the corresponding dialog view for this preference is bound

See also
`EditTextPreference.OnBindEditTextListener`

setText

Added in 1.0.0

public void setText(@Nullable String text)

Saves the text to the current data storage.

Parameters
`@Nullable String text`	The text to save

shouldDisableDependents

public boolean shouldDisableDependents()

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

Returns
`boolean`	`true` if the dependents should be disabled, otherwise false

Protected methods

onGetDefaultValue

protected Object onGetDefaultValue(@NonNull 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.

Parameters
`@NonNull TypedArray a`	The set of attributes
`int index`	The index of the default value attribute

Returns
`Object`	The default value of this preference type

onRestoreInstanceState

protected void onRestoreInstanceState(@Nullable 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
`@Nullable Parcelable state`	The saved state that had previously been returned by `onSaveInstanceState`.

See also
`onSaveInstanceState`
`restoreHierarchyState`

onSaveInstanceState

protected @Nullable 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
`@Nullable 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`.

See also
`onRestoreInstanceState`
`saveHierarchyState`

onSetInitialValue

protected void onSetInitialValue(Object defaultValue)

Implement this to set the initial value of the preference.

If you are persisting values to SharedPreferences or a PreferenceDataStore you should restore the saved value for the preference.

If you are not persisting values, or there is no value saved for the preference, you should set the value of the preference to defaultValue.

Parameters
`Object defaultValue`	The default value for the preference if set, otherwise `null`.
