Known Direct Subclasses

EditTextPreferenceDialogFragmentCompat,ListPreferenceDialogFragmentCompat,MultiSelectListPreferenceDialogFragmentCompat

Abstract base class which presents a dialog associated with a DialogPreference. Since the preference object may not be available during fragment re-creation, the necessary information for displaying the dialog is read once during the initial call to onCreate(Bundle) and saved/restored in the saved instance state. Custom subclasses should also follow this pattern.

String ARG_KEY

Constant Value: "key"

Public constructors

PreferenceDialogFragmentCompat

added in version 24.1.0

PreferenceDialogFragmentCompat ()

Public methods

getPreference

added in version 24.1.0

DialogPreference getPreference ()

Get the preference that requested this dialog. Available after onCreate(Bundle) has been called on the PreferenceFragmentCompat which launched this dialog.

Returns
`DialogPreference`	The `DialogPreference` associated with this dialog.

onClick

added in version 24.1.0

void onClick (DialogInterface dialog, 
                int which)

Parameters
`dialog`	`DialogInterface`
`which`	`int`

onCreate

added in version 24.1.0

void onCreate (Bundle savedInstanceState)

Called to do initial creation of a fragment. This is called after onAttach(Activity) and before onCreateView(LayoutInflater, ViewGroup, Bundle).

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(Bundle).

Any restored child fragments will be created before the base Fragment.onCreate method returns.

Parameters
`savedInstanceState`	`Bundle`: If the fragment is being re-created from a previous saved state, this is the state.

onCreateDialog

added in version 24.1.0

Dialog onCreateDialog (Bundle savedInstanceState)

Override to build your own custom Dialog container. This is typically used to show an AlertDialog instead of a generic Dialog; when doing so, onCreateView(LayoutInflater, ViewGroup, Bundle) does not need to be implemented since the AlertDialog takes care of its own content.

This method will be called after onCreate(Bundle) and before onCreateView(LayoutInflater, ViewGroup, Bundle). The default implementation simply instantiates and returns a Dialog class.

Note: DialogFragment own the Dialog.setOnCancelListener and Dialog.setOnDismissListener callbacks. You must not set them yourself. To find out about these events, override onCancel(DialogInterface) and onDismiss(DialogInterface).

Parameters
`savedInstanceState`	`Bundle`: The last saved instance state of the Fragment, or null if this is a freshly created Fragment.

Returns
`Dialog`	Return a new Dialog instance to be displayed by the Fragment.

onDialogClosed

added in version 24.1.0

void onDialogClosed (boolean positiveResult)

Parameters
`positiveResult`	`boolean`

onDismiss

added in version 24.1.0

void onDismiss (DialogInterface dialog)

Parameters
`dialog`	`DialogInterface`

onSaveInstanceState

added in version 24.1.0

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(Bundle), onCreateView(LayoutInflater, ViewGroup, Bundle), and onActivityCreated(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.

Protected methods

onBindDialogView

added in version 24.1.0

void onBindDialogView (View view)

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

Make sure to call through to the superclass implementation.

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

onCreateDialogView

added in version 24.1.0

View onCreateDialogView (Context context)

Creates the content view for the dialog (if a custom content view is required). By default, it inflates the dialog layout resource if it is set.

Parameters
`context`	`Context`

Returns
`View`	The content View for the dialog.

See also:

setLayoutResource(int)

onPrepareDialogBuilder

added in version 24.1.0

void onPrepareDialogBuilder (AlertDialog.Builder builder)

Prepares the dialog builder to be shown when the preference is clicked. Use this to set custom properties on the dialog.

Do not create() or show().

Parameters
`builder`	`AlertDialog.Builder`
