I've been looking for a while and I have not managed to figure out how to make a protected Dialog onCreateDialog (int id), which can be accessed from several activities by id sent by ShowDialog (id)

With public void Dialog onCreateDialog (int id) enough I guess, but the problem is, that according to the user to choose one option or another, you must go to an activity or another, and that's the part that I can not implement or understand how should.

For example, if striking B will accept me, and if I click cancel I go to C.

Right now I have repeated onCreateDialog protected Dialog (int id) in each activity and managing their own dialogue, something I think that nothing is efficient.

Any idea where to get the shots?

If I understood your question correctly, something like this.

public class DialogFactory
{

 public static int DIALOG_USED_BY_A_LOT_OF_ACTIVITIES_ID = 0;
 ....

 public Dialog getDialogUsedByALotOfActivities(Activity activity)
 {

  // Create and return dialog with activity context;
 }
}

public class OneActivityThatUsesDialog extends Activity
{

 private void showDialogUsedByALotOfActivities()
 {

  showDialog(DialogFactory.DIALOG_USED_BY_A_LOT_OF_ACTIVITIES_ID);
 }

 protected Dialog onCreateDialog(int id)
 {

  if (id == DialogFactory.DIALOG_USED_BY_A_LOT_OF_ACTIVITIES_ID)

   return DialogFactory.getDialogUsedByALotOfActivities(this);
 }
}

It's not the prettiest solution, but Dialogs have always been one of the worse parts of Android.

Also look at DialogFragment, they might have improved things with the newest android version.
