How to make my ImageView zoomable?
提问by capecrawler
Can anyone help on how to use the matrix scaletype to zoom an imageview and also how to use the translate method so that it can be focused at the center? I have tried using webview to be able to use the zooming and scrolling functionalities i needed but it is not nice to look at.
