I'm developing an app in Android where I customize an View and I draw some canvas with Bitmap. This bitmap are dirrent among them. So I'm able to move them with finger ( generating an ontouchevent ). If I decide to do the pinch to zoom IN OR OUT they can not move them or can not but remain in the portion of the screen that was before zooming out

I do not know if I have explained very well , but it is difficult to exert. I googled or everywhere but found nothing.

Thanks

leave `Canvas` as it is, better use `Canvas#drawBitmap(Bitmap, Matrix, Paint)` – pskink Nov 13 '15 at 10:39

you dont move the `Canvas`, move the `Matrix` instead, see [here](http://stackoverflow.com/a/21657145/2252830) – pskink Nov 13 '15 at 11:51
