DialogFragment

class DialogFragment : Fragment, DialogInterface.OnCancelListener, DialogInterface.OnDismissListener

kotlin.Any
   ↳ androidx.fragment.app.Fragment
     ↳ androidx.fragment.app.DialogFragment

Static library support version of the framework's android.app.DialogFragment. Used to write apps that run on platforms prior to Android 3.0. When running on Android 3.0 or above, this implementation is still used; it does not try to switch to the framework's implementation. See the framework SDK documentation for a class overview.

Summary

Constants
const Int

Style for setStyle: a basic, normal dialog.

Constants

STYLE_NORMAL

const val STYLE_NORMAL = 0: Int

Style for setStyle: a basic, normal dialog.

STYLE_NO_FRAME

const val STYLE_NO_FRAME = 2: Int

Style for setStyle: don't draw any frame at all; the view hierarchy returned by onCreateView is entirely responsible for drawing the dialog.

STYLE_NO_INPUT

const val STYLE_NO_INPUT = 3: Int

Style for setStyle: like STYLE_NO_FRAME, but also disables all input to the dialog. The user can not touch it, and its window will not receive input focus.

const val STYLE_NO_TITLE = 1: Int

Style for setStyle: don't include a title area.

Public constructors

DialogFragment

DialogFragment()

Constructor used by the default FragmentFactory. You must set a custom FragmentFactory if you want to use a non-default constructor to ensure that your constructor is called when the fragment is re-instantiated.

It is strongly recommended to supply arguments with setArguments and later retrieved by the Fragment with getArguments. These arguments are automatically saved and restored alongside the Fragment.

Applications should generally not implement a constructor. Prefer onAttach instead. It is the first place application code can run where the fragment is ready to be used - the point where the fragment is actually associated with its context.

DialogFragment

DialogFragment(contentLayoutId: @LayoutRes Int)

Alternate constructor that can be called from your default, no argument constructor to provide a default layout that will be inflated by onCreateView. 

class MyDialogFragment extends DialogFragment {
  public MyDialogFragment() {
    super(R.layout.dialog_fragment_main);
  }
}
You must set a custom FragmentFactory if you want to use a non-default constructor to ensure that your constructor is called when the fragment is re-instantiated.

DialogFragment
onCreateView

Public functions

dismiss

fun dismiss(): Unit

Dismiss the fragment and its dialog. If the fragment was added to the back stack, all back stack state up to and including this entry will be popped. Otherwise, a new transaction will be committed to remove the fragment.

dismissAllowingStateLoss

fun dismissAllowingStateLoss(): Unit

Version of dismiss that uses FragmentTransaction.commitAllowingStateLoss(). See linked documentation for further details.

dismissNow

@MainThread
fun dismissNow(): Unit

Version of dismiss that uses commitNow. See linked documentation for further details.

getDialog

fun getDialog(): Dialog?

Return the Dialog this fragment is currently controlling.

See also
requireDialog

getShowsDialog

fun getShowsDialog(): Boolean

Return the current value of setShowsDialog.

getTheme

fun getTheme(): @StyleRes Int

isCancelable

fun isCancelable(): Boolean

Return the current value of setCancelable.

onActivityCreated

@MainThread
fun onActivityCreated(savedInstanceState: Bundle?): Unit

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 and before #onViewStateRestored(Bundle).

onAttach

@MainThread
fun onAttach(context: Context): Unit

Called when a fragment is first attached to its context. onCreate will be called after this.

onCancel

fun onCancel(dialog: DialogInterface): Unit

onCreate

@MainThread
fun onCreate(savedInstanceState: Bundle?): Unit

Called to do initial creation of a fragment. This is called after onAttach and before onCreateView.

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, add a androidx.lifecycle.LifecycleObserver on the activity's Lifecycle, removing it when it receives the CREATED callback.

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

@MainThread
fun onCreateDialog(savedInstanceState: Bundle?): Dialog

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 does not need to be implemented since the AlertDialog takes care of its own content.

This method will be called after onCreate and immediately before onCreateView. 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 and onDismiss.

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.

onDestroyView

@MainThread
fun onDestroyView(): Unit

Remove dialog.

onDetach

@MainThread
fun onDetach(): Unit

Called when the fragment is no longer attached to its activity. This is called after onDestroy.

onDismiss

fun onDismiss(dialog: DialogInterface): Unit

onGetLayoutInflater

fun onGetLayoutInflater(savedInstanceState: Bundle?): LayoutInflater

Returns the LayoutInflater used to inflate Views of this Fragment. The default implementation will throw an exception if the Fragment is not attached.

If this is called from within onCreateDialog, the layout inflater from onGetLayoutInflater, without the dialog theme, will be returned.

onSaveInstanceState

@MainThread
fun onSaveInstanceState(outState: Bundle): Unit

Called to ask the fragment to save its current dynamic state, so it can later be reconstructed in a new instance if 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, onCreateView, and onViewCreated.

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

@MainThread
fun onStart(): Unit

Called when the Fragment is visible to the user. This is generally tied to Activity.onStart of the containing Activity's lifecycle.

onStop

@MainThread
fun onStop(): Unit

Called when the Fragment is no longer started. This is generally tied to Activity.onStop of the containing Activity's lifecycle.

onViewStateRestored

@MainThread
fun onViewStateRestored(savedInstanceState: Bundle?): Unit

Called when all saved state has been restored into the view hierarchy of the fragment. This can be used to do initialization based on saved state that you are letting the view hierarchy track itself, such as whether check box widgets are currently checked. This is called after onViewCreated and before onStart.

Parameters
savedInstanceState: Bundle?

If the fragment is being re-created from a previous saved state, this is the state.

requireDialog

fun requireDialog(): Dialog

Return the Dialog this fragment is currently controlling.

Throws
java.lang.IllegalStateException: java.lang.IllegalStateException

if the Dialog has not yet been created (before onCreateDialog) or has been destroyed (after onDestroyView.
See also
getDialog

setCancelable

fun setCancelable(cancelable: Boolean): Unit

Control whether the shown Dialog is cancelable. Use this instead of directly calling Dialog.setCancelable(boolean), because DialogFragment needs to change its behavior based on this.

Parameters
cancelable: Boolean

If true, the dialog is cancelable. The default is true.

setShowsDialog

fun setShowsDialog(showsDialog: Boolean): Unit

Controls whether this fragment should be shown in a dialog. If not set, no Dialog will be created and the fragment's view hierarchy will thus not be added to it. This allows you to instead use it as a normal fragment (embedded inside of its activity).

This is normally set for you based on whether the fragment is associated with a container view ID passed to FragmentTransaction.add(int, Fragment). If the fragment was added with a container, setShowsDialog will be initialized to false; otherwise, it will be true.

If calling this manually, it should be called in onCreate as calling it any later will have no effect.

Parameters
showsDialog: Boolean

If true, the fragment will be displayed in a Dialog. If false, no Dialog will be created and the fragment's view hierarchy left undisturbed.

setStyle

fun setStyle(style: Int, theme: @StyleRes Int): Unit

Call to customize the basic appearance and behavior of the fragment's dialog. This can be used for some common dialog behaviors, taking care of selecting flags, theme, and other options for you. The same effect can be achieve by manually setting Dialog and Window attributes yourself. Calling this after the fragment's Dialog is created will have no effect.

Parameters
style: Int

Selects a standard style: may be STYLE_NORMAL, STYLE_NO_TITLE, STYLE_NO_FRAME, or STYLE_NO_INPUT.
theme: @StyleRes Int

Optional custom theme. If 0, an appropriate theme (based on the style) will be selected for you.

show

fun show(manager: FragmentManager, tag: String?): Unit

Display the dialog, adding the fragment to the given FragmentManager. This is a convenience for explicitly creating a transaction, adding the fragment to it with the given tag, and committing it. This does not add the transaction to the fragment back stack. When the fragment is dismissed, a new transaction will be executed to remove it from the activity.

Parameters
manager: FragmentManager

The FragmentManager this fragment will be added to.
tag: String?

The tag for this fragment, as per FragmentTransaction.add.

show

fun show(transaction: FragmentTransaction, tag: String?): Int

Display the dialog, adding the fragment using an existing transaction and then committing the transaction.

Parameters
transaction: FragmentTransaction

An existing transaction in which to add the fragment.
tag: String?

The tag for this fragment, as per FragmentTransaction.add.
Returns
Int

Returns the identifier of the committed transaction, as per FragmentTransaction.commit().

showNow

fun showNow(manager: FragmentManager, tag: String?): Unit

Display the dialog, immediately adding the fragment to the given FragmentManager. This is a convenience for explicitly creating a transaction, adding the fragment to it with the given tag, and calling commitNow. This does not add the transaction to the fragment back stack. When the fragment is dismissed, a new transaction will be executed to remove it from the activity.

Parameters
manager: FragmentManager

The FragmentManager this fragment will be added to.
tag: String?

The tag for this fragment, as per FragmentTransaction.add.
