android-imageview

问题 I want to create ImageView like this (right side of the image): I have it in CardView layout so I have rounded corners of the card but I need to create rounded left bottom corner of the image alone (or with top right). I tried several options but nothing work correctly. How can I do this? Do you have some tip? 回答1: You can use this library and put your ImageView inside the Layout https://github.com/JcMinarro/RoundKornerLayouts and can set the radius for specific corners like this

问题 So I have several ImageViews in a single Activity and all of them use the same image bitmap from a resource. ImageViewOne.setImageResource(R.drawable.frequently_used_image); ImageViewTwo.setImageResource(R.drawable.frequently_used_image); ImageViewThree.setImageResource(R.drawable.frequently_used_image); Does android allocate memory to load the bitmap once and reuse it for all other ImageViews using the same resource? Or does it load the bitmap each time it is set to an ImageView? Thanks! 回答1

问题 In my application, i am moving image around the screen by using onTouchListener . I have another two images in the same view. My problem is that, when the moving image, touches any of the other images, i need to perform a certain action (that means if images are intersected, then do something). How can this be achieved?.Please help me asap Thanks in Advance. 回答1: You should be able to use Rect.intersects(Rect, Rect) , like this example: Rect myViewRect = new Rect(); myView.getHitRect
