问题
i am cropping a image by the help of a child relative layout and i am moving it by motion event over a parent relative layout(containing image-view to be cropped). ..but when i rotate parent layout (in which i have the image view ) by 90 deg. the behavior of motion event co-ordinate changes,and does not work(drag and zoom of child layout)properly.. please somebody tell me how to fix this..i have done some research and found about the AXIS_ORIENTATION in motionevent class but did not get any example regarding to it. thanks in advance :)
