：

DialogFragment dialog = NewCategoryDialog.getInstance(); 
dialog.show(getFragmentManager(), DIALOG_NEW_CATEGORY_TAG); 

は私がgetAttributes().windowAnimationsとsetWindowAnimations()の両方を試してみました、ともonActivityCreated、onCreateDialog、onCreateViewでそれを入れて、それを試してみましたが、動作するようには思えません。

このように試してください。

@Override 
    public void onActivityCreated(Bundle savedInstanceState) { 
     super.onActivityCreated(savedInstanceState); 

     if (getDialog().getWindow() != null) { 
      dialog.getWindow().getAttributes().windowAnimations = R.style.DialogSlideFromBottomAnimation; 
     } 
    }
