Implementing a crop image in Android

I am trying to implement a crop image for my app.
What I want to do is that I've an imageview set to 300x300 .I am taking images from
CAMERA and GALLERY now the images can be bigger than 300x300. I want to implement
a cropping tool using which I can drag the image inside imageview so that I can select the useful portion of 300x300 of the image.
I want to implement the same feature which this app implemented for cropping.
Can anyone point me in the right direction ?

Try this:

But if you want to drag and fit useful portion of a image in a Imageview than you can use MultiTouch View.
https://code.google.com/p/android-multitouch-controller/
You can move the image on a custom view. Zoom and Pinch. Once you found the useful area. Take a screenshot of the imageview.
hope any of the solutions helps :)

how to show images from a folder in sd card into grid view something like image gallery

I need a tutorial where in I can get images from a folder to display in grid view and then on click of the image in grid I can see full view and swipe functionality
any tutorial or code here please
thanks in advance

I think this is not hard to perform.
Find out your SD card folder path, scan and store image files and get image path in the SD card folder, get the bitmap from stored image path and put in to gridview. set gridview item selected listener to display image when click on a item.
There will not have a example code contains all the function you need. you can divide the problem to small ones, then try to solve it piece by piece. For example: solve scan image file from a folder first.

If the code given in gitHub can not fetch your images then paste the
path here which is used to fetch the images.
To set images in grid view, you already got the code. But now you
want to slide the images one by one. Then I can give you a hint that
use gallery view of android. It provides slider of small images. You
need to change the resolution of images. You need to combine these 2
views.

Implementing ImageViewTouch on Gallery

I have a code with a ImageViewTouch image that have pinch zoom, but i cant implement it on the gallery, i tried everything like setting in the ImageAdapter, it works but the Gallery wont scroll.
I think that another solution will be using a ImageSwitcher.
I ask if somebody have a code of a Gallery Implementing a ImageView extension with scroll enabled, or a ImageSwitcher with the Gallery scroll (No Animations).

The only thing I've found that works is to set an OnTouchListener on the Gallery itself, and then manually map the coordinates of the touch event to the underlying view with getLocationOnScreen.
