Blurry rendering on Android

I need for some workaround transform a widget-built DialogBox into a ImageView.

To do that开发者_如何学编程, I created a Canvas that saves on a Bitmap (using Canvas someCanvas = new Canvas(someBitmap); )

Then I take my dialog box and do: dialogBoxFrameLayout.Draw(someCanvas);

But the result is blurry. VERY blurry. How I fix it?
