How to use

[thsstudio]

Hi, I find out the class you made is very useful as in description. Could you pls explain how I can use this class replaced for ImageView? After I add it in XML and set bitmap for it, what should I do so that it can listen to touch event and can rotate/zoom/move?
Thank you a lot!

Hello, OK, I will make sample project and upload.

I just add sample project(Android Studio).

Most simple usage is just replacing ImageView to ZoomImageView and add image using #setImageBitmap, #setImageURI etc. You don't need to handle touch event by yourself.

Thank you a lot! It's very helpful for me. But could I have 1 more question? I find the zoom out work perfectly but the zoom in function is not working, do I need to change any constant in your class?

Hello,

Zooming range is from mMinScale to mMaxScale and mMinScale is calculated in #init method so that image fit the view. So if you want to much smaller value(to zoom out more), multiply smaller rate that you want. Don't set smaller or equal value than zero. If you set minus value, image will look horizontally and vertically mirror flipped.
