PreferenceFragment

Kotlin |Java

public abstract class PreferenceFragment
extends Fragment

java.lang.Object
↳	android.app.Fragment
	↳	android.preference.PreferenceFragment

This class was deprecated in API level 28.
Use the AndroidX Preference Library for consistent behavior across all devices. For more information on using the AndroidX Preference Library see Settings.

Shows a hierarchy of Preference objects as lists. These preferences will automatically save to SharedPreferences as the user interacts with them. To retrieve an instance of SharedPreferences that the preference hierarchy in this fragment will use, call PreferenceManager.getDefaultSharedPreferences(android.content.Context) with a context in the same package as this fragment.

Furthermore, the preferences shown will follow the visual style of system preferences. It is easy to create a hierarchy of preferences (that can be shown on multiple screens) via XML. For these reasons, it is recommended to use this fragment (as a superclass) to deal with preferences in applications.

A PreferenceScreen object should be at the top of the preference hierarchy. Furthermore, subsequent PreferenceScreen in the hierarchy denote a screen break--that is the preferences contained within subsequent PreferenceScreen should be shown on another screen. The preference framework handles showing these other screens from the preference hierarchy.

The preference hierarchy can be formed in multiple ways:

From an XML file specifying the hierarchy

From different Activities that each specify its own preferences in an XML file via Activity meta-data

From an object hierarchy rooted with PreferenceScreen

To inflate from XML, use the addPreferencesFromResource(int). The root element should be a PreferenceScreen. Subsequent elements can point to actual Preference subclasses. As mentioned above, subsequent PreferenceScreen in the hierarchy will result in the screen break.

To specify an Intent to query Activities that each have preferences, use addPreferencesFromIntent(Intent). Each Activity can specify meta-data in the manifest (via the key PreferenceManager.METADATA_KEY_PREFERENCES) that points to an XML resource. These XML resources will be inflated into a single preference hierarchy and shown by this fragment.

To specify an object hierarchy rooted with PreferenceScreen, use setPreferenceScreen(android.preference.PreferenceScreen).

As a convenience, this fragment implements a click listener for any preference in the current hierarchy, see onPreferenceTreeClick(android.preference.PreferenceScreen, android.preference.Preference).

public PreferenceFragment ()

Public methods

addPreferencesFromIntent

Added in API level 11

public void addPreferencesFromIntent (Intent intent)

Adds preferences from activities that match the given Intent.

Parameters
`intent`	`Intent`: The `Intent` to query activities.

addPreferencesFromResource

Added in API level 11

public void addPreferencesFromResource (int preferencesResId)

Inflates the given XML resource and adds the preference hierarchy to the current preference hierarchy.

Parameters
`preferencesResId`	`int`: The XML resource ID to inflate.

findPreference

Added in API level 11

public Preference findPreference (CharSequence key)

Finds a Preference based on its key.

Parameters
`key`	`CharSequence`: The key of the preference to retrieve.

Returns
`Preference`	The `Preference` with the key, or null.

See also:

PreferenceGroup.findPreference(CharSequence)

getPreferenceManager

Added in API level 11

public PreferenceManager getPreferenceManager ()

Returns the PreferenceManager used by this fragment.

Returns
`PreferenceManager`	The `PreferenceManager`.

getPreferenceScreen

Added in API level 11

public PreferenceScreen getPreferenceScreen ()

Gets the root of the preference hierarchy that this fragment is showing.

Returns
`PreferenceScreen`	The `PreferenceScreen` that is the root of the preference hierarchy.

onActivityCreated

Added in API level 11

public void onActivityCreated (Bundle savedInstanceState)

Called when the fragment's activity has been created and this fragment's view hierarchy instantiated. It can be used to do final initialization once these pieces are in place, such as retrieving views or restoring state. It is also useful for fragments that use setRetainInstance(boolean) to retain their instance, as this callback tells the fragment when it is fully associated with the new activity instance. This is called after onCreateView(LayoutInflater, ViewGroup, Bundle) and before onViewStateRestored(android.os.Bundle).
If you override this method you must call through to the superclass implementation.

Parameters
`savedInstanceState`	`Bundle`: This value may be `null`.

onActivityResult

Added in API level 11

public void onActivityResult (int requestCode, 
                int resultCode, 
                Intent data)

Receive the result from a previous call to startActivityForResult(android.content.Intent, int). This follows the related Activity API as described there in Activity.onActivityResult(int, int, Intent).

Parameters
`requestCode`	`int`: The integer request code originally supplied to startActivityForResult(), allowing you to identify who this result came from.
`resultCode`	`int`: The integer result code returned by the child activity through its setResult().
`data`	`Intent`: An Intent, which can return result data to the caller (various data can be attached to Intent "extras").

onCreate

Added in API level 11

public void onCreate (Bundle savedInstanceState)

Called to do initial creation of a fragment. This is called after onAttach(android.app.Activity) and before onCreateView(android.view.LayoutInflater, android.view.ViewGroup, android.os.Bundle), but is not called if the fragment instance is retained across Activity re-creation (see setRetainInstance(boolean)).

Note that this can be called while the fragment's activity is still in the process of being created. As such, you can not rely on things like the activity's content view hierarchy being initialized at this point. If you want to do work once the activity itself is created, see onActivityCreated(android.os.Bundle).

If your app's targetSdkVersion is Build.VERSION_CODES.M or lower, child fragments being restored from the savedInstanceState are restored after onCreate returns. When targeting Build.VERSION_CODES.N or above and running on an N or newer platform version they are restored by Fragment.onCreate.

If you override this method you must call through to the superclass implementation.

Parameters
`savedInstanceState`	`Bundle`: This value may be `null`.

onCreateView

Added in API level 11

public View onCreateView (LayoutInflater inflater, 
                ViewGroup container, 
                Bundle savedInstanceState)

Called to have the fragment instantiate its user interface view. This is optional, and non-graphical fragments can return null (which is the default implementation). This will be called between onCreate(android.os.Bundle) and onActivityCreated(android.os.Bundle).

If you return a View from here, you will later be called in onDestroyView() when the view is being released.

Parameters
`inflater`	`LayoutInflater`: The LayoutInflater object that can be used to inflate any views in the fragment,
`container`	`ViewGroup`: This value may be `null`.
`savedInstanceState`	`Bundle`: This value may be `null`.

Returns
`View`	Return the View for the fragment's UI, or null.

onDestroy

Added in API level 11

public void onDestroy ()

Called when the fragment is no longer in use. This is called after onStop() and before onDetach().
If you override this method you must call through to the superclass implementation.

onDestroyView

Added in API level 11

public void onDestroyView ()

Called when the view previously created by onCreateView(LayoutInflater, ViewGroup, Bundle) has been detached from the fragment. The next time the fragment needs to be displayed, a new view will be created. This is called after onStop() and before onDestroy(). It is called regardless of whether onCreateView(LayoutInflater, ViewGroup, Bundle) returned a non-null view. Internally it is called after the view's state has been saved but before it has been removed from its parent.
If you override this method you must call through to the superclass implementation.

onPreferenceTreeClick

Added in API level 11

public boolean onPreferenceTreeClick (PreferenceScreen preferenceScreen, 
                Preference preference)

Parameters
`preferenceScreen`	`PreferenceScreen`
`preference`	`Preference`

Returns
`boolean`

onSaveInstanceState

Added in API level 11

public void onSaveInstanceState (Bundle outState)

Called to ask the fragment to save its current dynamic state, so it can later be reconstructed in a new instance of its process is restarted. If a new instance of the fragment later needs to be created, the data you place in the Bundle here will be available in the Bundle given to onCreate(android.os.Bundle), onCreateView(android.view.LayoutInflater, android.view.ViewGroup, android.os.Bundle), and onActivityCreated(android.os.Bundle).

This corresponds to Activity.onSaveInstanceState(Bundle) and most of the discussion there applies here as well. Note however: this method may be called at any time before onDestroy(). There are many situations where a fragment may be mostly torn down (such as when placed on the back stack with no UI showing), but its state will not be saved until its owning activity actually needs to save its state.

Parameters
`outState`	`Bundle`: Bundle in which to place your saved state.

onStart

Added in API level 11

public void onStart ()

Called when the Fragment is visible to the user. This is generally tied to Activity.onStart of the containing Activity's lifecycle.
If you override this method you must call through to the superclass implementation.

onStop

Added in API level 11

public void onStop ()

Called when the Fragment is no longer started. This is generally tied to Activity.onStop of the containing Activity's lifecycle.
If you override this method you must call through to the superclass implementation.

onViewCreated

Added in API level 13
Deprecated in API level 28

public void onViewCreated (View view, 
                Bundle savedInstanceState)

Called immediately after onCreateView(android.view.LayoutInflater, android.view.ViewGroup, android.os.Bundle) has returned, but before any saved state has been restored in to the view. This gives subclasses a chance to initialize themselves once they know their view hierarchy has been completely created. The fragment's view hierarchy is not however attached to its parent at this point.

Parameters
`view`	`View`: The View returned by `onCreateView(android.view.LayoutInflater, android.view.ViewGroup, android.os.Bundle)`.
`savedInstanceState`	`Bundle`: This value may be `null`.

setPreferenceScreen

Added in API level 11

public void setPreferenceScreen (PreferenceScreen preferenceScreen)

Sets the root of the preference hierarchy that this fragment is showing.

Parameters
`preferenceScreen`	`PreferenceScreen`: The root `PreferenceScreen` of the preference hierarchy.
