How to enable Zoom and Pan functions in Android Gallery widget?

The ImageView in the Android Gallery widget does not provide Zoom and 开发者_高级运维Pan functions.

Does anyone know how to enable those functions ?

Thanks.

There is no "zoom and pan" for ImageView or for Gallery. You either need to find third-party code that provides this, or write it yourself.

Here are some links for implementing your own zoom logic on an ImageView:
