orientation

问题 I am writing an application which in portrait view has a gallery at the top and when you click a picture it will inflate and fill the entire screen. This works however in landscape mode the gallery covers up most of the picture and it in general looks crappy. I made a GridView for landscape mode. The problem I am having now is to change it from the gallery activity to the Gridview activity when the orientation changes. Any ideas? 回答1: Add this to your Activity: @Override public void

问题 Right now this code will only rotate my image 90 degrees. I can not figure out how to rotate it 270 degrees. transform = transform.rotated(by: CGFloat(Double.pi)) 回答1: Start with some basic math. 360° = 2π. 180° = π. 90° = π/2. 270° = 3π/2. This means your posted code is rotating 180 degrees. Use Double.pi/2 for 90° and 3*Double.pi/2 for 270°. 来源： https://stackoverflow.com/questions/43619944/how-to-get-image-orientation-to-rotate-270-degrees-swift3

问题 I'm preparing a series of reports in ssrs 2008. In order to comply with the requirements the first page of the report has to be in portrait orientation, while the rest of the document must use landscape orientation. I know there is no way to do this OOTB ( or perhaps you can prove me wrong :P ). I was wondering if there was a way to implement a custom renderer that could play with Page Orientation based on page breaks, or any other solution you knew of. I was reading through the questions and

问题 I am programming a VST DSP plugin in c++. I am creating a series of band pass filters in a 'filterbank'. I have implemented a filter class in my header (including function) and built constructor/destructor correctly in .cpp. I can pass values to the method and return them also. However, the issues lays in the area of storing data in buffers in the function. It seems that every time the function method is called that the values stored in the buffer are reset (or alternatively, are not stored

问题 I have an app designed for iPhone that makes use of the UIImagePickerController. The app run in landscape only up until the image picker comes into view in its default portrait. Problem 1: On the iPhone when I rotate the device to portrait to view the image library the image picker view seems to do a flip as if rotating from landscape to portrait? Problem 2: I get the dreaded warning Using two-stage rotation animation. To use the smoother single-stage animation, this application must remove

问题 I am creating an application with Landscape Right orientation. For that I set the Initial interface orientation property in info.plist file. Then in every view I handled - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return(interfaceOrientation==UIInterfaceOrientationLandscapeRight); } It works fine in simulator but in device its behave differently. My first view is in proper orientation. There is is popover which display another view that comes

问题 My web page is 980px. Safari on iPad does not fit it in a Portrait mode. According to Apple, you do not have to do anything to fit your website for all orientations on iPad. But in Portrait mode, my web page does not fit at all. It's about 20% off the viewport. I tried all available fixes unsuccessfully: <meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1"> or <meta name="viewport" content="width=980"> and <style type="text/css"> @media only screen and (min

问题 Instead of doing my own sensor fusion, I am using the Quaternions available from iOS and converting them to Euler angles. I walked around in a rectangle shape for few times and I observe that the shape is not as expected. I am plotting the shape by plotting the Yaw values. Please see below. It appears that the heading deviates significantly. I maintained the path while walking. How do I correct the Yaw values so I get correct rectangle shape. 来源： https://stackoverflow.com/questions/30941993

问题 I am looking to see if its possible to get the device orientation of a video to check and see if its needs to be rotated in PHP with ffmpeg. Is this even possible? I have done it easy enough with images, but I have not found anything so far to help with this. 回答1: Device orientation is a client side property, and PHP is strictly server-side. Quickly googling led me to this page, which has an example for the iPhone. The author offers this function, which is called on page load: function
