问题 I want to retain the state of the RecyclerView's selected item whenever the screen orientation changes, but whenever I change the orientation, the selected item does not retain its state. So I save the position of the selected item and on orientation change in onResume() .

问题 (please read UPDATE 3 at the end)I'm developing an app that continually works with the sensors of device, works with Accelerometer and Magnetic sensors to retrieve the orientation of device(the purpose is mentioned here). in other words, my app needs to know the orientation of device in Real-time(however this is never possible, so as fast as possible instead, but really as fast as possible !). as mentioned in professional Android 4 Application Development by Reto Meier : The accelerometers

问题 I have 2 images, one in portrait mode, and the other in landscape mode. What is the best way to switch these images when a mobile device view rotation takes place? Currently I just display the portrait image. And when the device rotates to landscape mode the portrait image is simply stretched. Should I be checking within the orientation rotation handler and simply reset the image to the proper orientational image (i.e. set it manually based on the orientation)?? Thanks! 回答1: I found three
