Zoom ImageView in android like Instagram

How can I zoom ImageView like Instagram. I mean changing the size of imageview, not zooming the image inside the Imageview.

For zooming the image inside the Imageview, there are a lot of samples but I want something like Instagram image zooming

Any code or hint? Thanks.

Solution

  • I would recommend these two libraries:

    1. PhotoView

    2. ImageViewZoom

    For PhotoView, you just have to create an attacher and "attach" it to your ImageView.

    Some code

    // After getting your imageImage view, attach it like the following
PhotoViewAttacher yourAttacher = new PhotoViewAttacher(yourImageView);

    With just this code, you'll be able to zoom in/out/whatever on yourImageView. Check the links above for more details.

    EDIT

    Instagram has changed a lot since this answer was posted, and the libraries I recommended above might not provide the experience you are looking for.
