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.
