PreferenceScreen

public final class PreferenceScreen
extends PreferenceGroup implements AdapterView.OnItemClickListener, DialogInterface.OnDismissListener

java.lang.Object
↳	android.preference.Preference
	↳	android.preference.PreferenceGroup
		↳	android.preference.PreferenceScreen

This class is deprecated.
Use the AndroidX Preference Library for consistent behavior across all devices. For more information on using the AndroidX Preference Library see Settings.

Represents a top-level Preference that is the root of a Preference hierarchy. A PreferenceActivity points to an instance of this class to show the preferences. To instantiate this class, use PreferenceManager#createPreferenceScreen(Context).

When a PreferenceActivity points to this, it is used as the root and is not shown (only the contained preferences are shown).
When it appears inside another preference hierarchy, it is shown and serves as the gateway to another screen of preferences (either by showing another screen of preferences as a Dialog or via a Context#startActivity(android.content.Intent) from the Preference#getIntent()). The children of this PreferenceScreen are NOT shown in the screen that this PreferenceScreen is shown in. Instead, a separate screen will be shown when this preference is clicked.

Here's an example XML layout of a PreferenceScreen:

 <PreferenceScreen
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:key="first_preferencescreen">
    <CheckBoxPreference
            android:key="wifi enabled"
            android:title="WiFi" />
    <PreferenceScreen
            android:key="second_preferencescreen"
            android:title="WiFi settings">
        <CheckBoxPreference
                android:key="prefer wifi"
                android:title="Prefer WiFi" />
        ... other preferences here ...
    </PreferenceScreen>
 </PreferenceScreen>

In this example, the "first_preferencescreen" will be used as the root of the hierarchy and given to a PreferenceActivity. The first screen will show preferences "WiFi" (which can be used to quickly enable/disable WiFi) and "WiFi settings". The "WiFi settings" is the "second_preferencescreen" and when clicked will show another screen of preferences such as "Prefer WiFi" (and the other preferences that are children of the "second_preferencescreen" tag).

From interface


        
          java.lang.Comparable


      compareTo(Preference o)

Compares this object with the specified object for order.

From interface


        
          android.widget.AdapterView.OnItemClickListener


      onItemClick(AdapterView<?> parent, View view, int position, long id)

Callback method to be invoked when an item in this AdapterView has been clicked.

From interface


        
          android.content.DialogInterface.OnDismissListener


      onDismiss(DialogInterface dialog)

This method will be invoked when the dialog is dismissed.

Public methods

public void bind (ListView listView)

Binds a ListView to the preferences contained in this PreferenceScreen via getRootAdapter(). It also handles passing list item clicks to the corresponding Preference contained by this PreferenceScreen.

Parameters
`listView`	`ListView`: The list view to attach to.

getDialog

public Dialog getDialog ()

Used to get a handle to the dialog. This is useful for cases where we want to manipulate the dialog as we would with any other activity or view.

Returns
`Dialog`

getRootAdapter

public ListAdapter getRootAdapter ()

Returns an adapter that can be attached to a PreferenceActivity or PreferenceFragment to show the preferences contained in this PreferenceScreen.

This PreferenceScreen will NOT appear in the returned adapter, instead it appears in the hierarchy above this PreferenceScreen.

This adapter's Adapter#getItem(int) should always return a subclass of Preference.

Returns
`ListAdapter`	An adapter that provides the `Preference` contained in this `PreferenceScreen`.

onDismiss

public void onDismiss (DialogInterface dialog)

This method will be invoked when the dialog is dismissed.

Parameters
`dialog`	`DialogInterface`: the dialog that was dismissed will be passed into the method

public void onItemClick (AdapterView parent, 
                View view, 
                int position, 
                long id)

Parameters
`parent`	`AdapterView`
`view`	`View`
`position`	`int`
`id`	`long`

Protected methods

isOnSameScreenAsChildren

protected boolean isOnSameScreenAsChildren ()

Whether this preference group should be shown on the same screen as its contained preferences.

Returns
`boolean`	True if the contained preferences should be shown on the same screen as this preference.

onClick

protected void onClick ()

Processes a click on the preference. This includes saving the value to the SharedPreferences. However, the overridden method should call callChangeListener(java.lang.Object) to make sure the client wants to update the preference's state with the new value.

onCreateRootAdapter

protected ListAdapter onCreateRootAdapter ()

Creates the root adapter.

Returns
`ListAdapter`	An adapter that contains the preferences contained in this `PreferenceScreen`.

See also:

getRootAdapter()

onRestoreInstanceState

protected 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

protected 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`.
