View with horizontal and vertical pan/drag and pinch-zoom

Question

Is it possible to have a view who supports horizontal and vertical pan/drag. On top of that, I want to be able to pinch to zoom and double tap to zoom. Does this view exists

Answer 1

This custom view is a subclass of the Android standard imageView and adds to it (multi)touch pan and zoom (and double tap zoom, as well):

It is similar to the MikeOrtiz's TouchImageView that you already know but adds some more features.

You can use it inside a view "stack" (an Android FrameLayout or something like that) together with the other textView(s) you need. (I mean a "pile" of views, like a pile of dishes or a stack of cards. In other words, a pile of views stacked one over the next on the Z axis.)

Moving all your views together requires that you take control of the Android Gestures (multitouch) mechanism and write the required code. There isn't any ready-to-use solution for your (quite complex) requirement. Have a look at this article:
