Usage

From source file:android.app.Activity.java

/**
 * Show a dialog managed by this activity.  A call to {@link #onCreateDialog(int, Bundle)}
 * will be made with the same id the first time this is called for a given
 * id.  From thereafter, the dialog will be automatically saved and restored.
 *
 * <em>If you are targeting {@link android.os.Build.VERSION_CODES#HONEYCOMB}
 * or later, consider instead using a {@link DialogFragment} instead.</em>
 *
 * <p>Each time a dialog is shown, {@link #onPrepareDialog(int, Dialog, Bundle)} will
 * be made to provide an opportunity to do any timely preparation.
 *
 * @param id The id of the managed dialog.
 * @param args Arguments to pass through to the dialog.  These will be saved
 * and restored for you.  Note that if the dialog is already created,
 * {@link #onCreateDialog(int, Bundle)} will not be called with the new
 * arguments but {@link #onPrepareDialog(int, Dialog, Bundle)} will be.
 * If you need to rebuild the dialog, call {@link #removeDialog(int)} first.
 * @return Returns true if the Dialog was created; false is returned if
 * it is not created because {@link #onCreateDialog(int, Bundle)} returns false.
 * //w  ww .j a va 2s.c o  m
 * @see Dialog
 * @see #onCreateDialog(int, Bundle)
 * @see #onPrepareDialog(int, Dialog, Bundle)
 * @see #dismissDialog(int)
 * @see #removeDialog(int)
 *
 * @deprecated Use the new {@link DialogFragment} class with
 * {@link FragmentManager} instead; this is also
 * available on older platforms through the Android compatibility package.
