Try this post, I believe this should help. It involves enabling the drawing cache and forcing it use that cache. Usually works on all views. Should work on MapView aswell

Code from the link

 private Bitmap getMapImage() {  
        /* Position map for output */  
        MapController mc = mapView.getController();  
        mc.setCenter(SOME_POINT);  
        mc.setZoom(16);  

        /* Capture drawing cache as bitmap */  
        mapView.setDrawingCacheEnabled(true);  
        Bitmap bmp = Bitmap.createBitmap(mapView.getDrawingCache());  
        mapView.setDrawingCacheEnabled(false);  

        return bmp;  
    }  

    private void saveMapImage() {  
        String filename = "foo.png";  
        File f = new File(getExternalFilesDir(null), filename);  
        FileOutputStream out = new FileOutputStream(f);  

        Bitmap bmp = getMapImage();  

        bmp.compress(Bitmap.CompressFormat.PNG, 100, out);  

        out.close();  
    }
