How to zoom whole activity on multi touch?

Question

Problem:

It\'s easy to zoom images and web views. But I want to zoom a whole activity. How can I do this?

Here, I provide wire-frame:

Answer 1

You can use setScaleX and setScaleY to zoom the complete activity view.

Then you need to set the pivot point with setPivotX and setPivotY.

The good examples with details for the whole activity zoom with multitouch:

1) MultiTouch for whole activity.

2) Zooming view completely.
