android.support.v4.app

Class DialogFragment

    • Constructor Detail

      • DialogFragment

        public DialogFragment()
    • Method Detail

      • setStyle

        public void setStyle(int style,
                    int theme)
        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 - Selects a standard style: may be STYLE_NORMAL, STYLE_NO_TITLE, STYLE_NO_FRAME, or STYLE_NO_INPUT.
        theme - Optional custom theme. If 0, an appropriate theme (based on the style) will be selected for you.
      • show

        public void show(FragmentManager manager,
                String tag)
        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 back stack. When the fragment is dismissed, a new transaction will be executed to remove it from the activity.
        Parameters:
        manager - The FragmentManager this fragment will be added to.
        tag - The tag for this fragment, as per FragmentTransaction.add.
      • show

        public int show(FragmentTransaction transaction,
               String tag)
        Display the dialog, adding the fragment using an existing transaction and then committing the transaction.
        Parameters:
        transaction - An existing transaction in which to add the fragment.
        tag - The tag for this fragment, as per FragmentTransaction.add.
        Returns:
        Returns the identifier of the committed transaction, as per FragmentTransaction.commit().
      • dismiss

        public void dismiss()
        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.
      • getDialog

        public Dialog getDialog()
      • getTheme

        public int getTheme()
      • setCancelable

        public void setCancelable(boolean cancelable)
        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 - If true, the dialog is cancelable. The default is true.
      • setShowsDialog

        public void setShowsDialog(boolean showsDialog)
        Controls whether this fragment should be shown in a dialog. If not set, no Dialog will be created in onActivityCreated(Bundle), 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.

        Parameters:
        showsDialog - If true, the fragment will be displayed in a Dialog. If false, no Dialog will be created and the fragment's view hierarchly left undisturbed.
      • onStart

        public void onStart()
        Description copied from class: Fragment
        Called when the Fragment is visible to the user. This is generally tied to Activity.onStart of the containing Activity's lifecycle.
        Overrides:
        onStart in class Fragment
      • onStop

        public void onStop()
        Description copied from class: Fragment
        Called when the Fragment is no longer started. This is generally tied to Activity.onStop of the containing Activity's lifecycle.
        Overrides:
        onStop in class Fragment
