acceleration

问题 Short version: Disabling hardware acceleration with android:hardwareAccelerated="false" in xml changes the background color of my Theme.Sherlock.Light.DarkActionBar theme to a whiter "white". EDIT: this used to be the main question. I changed the title to emphasize the second problem. Disabling hardware acceleration for the mapView only, causes constant redraws. Long version: AFAIK hardware acceleration is enabled by default on API level 14 and up. (reference) Since I'm building and testing

问题 This question already has answers here : Pygame doesn't let me use float for rect.move, but I need it (2 answers) Closed 7 days ago . When i move right using the right key, i accelerate to a max speed. When i release it, i do decelerate to a stop so that is fine. However, when moving left using the left key, and after releasing it, i continue moving at a fixed speed and then come to an abrupt stop after a short while. Any idea what could be wrong with my code? The original code is from http:/

问题 Is there a setting for the canvas context that will prevent its renderer from using hardware acceleration? I want to render without it, but don't want to ask the user to disable it from their chrome browser since that is counter-intuitive and doesn't provide a seamless workflow experience. 回答1: Short Answer: No, but it is at least being considered by those developing Chromium. MDN: CanvasContext2D In the page you'll find an internal method called demote . Long Answer: There's nothing

问题 What I am trying to do? Using the sensor of Android, I have collected lot of acceleration values when some diabetic patients were running to do physical exercise. Each acceleration value consists of three components: Acceleration in x axis, acceleration in y axis, acceleration in z axis. Then, I need to calculate the total magnitude of each acceleration value and it's direction. Then, what does create the problem? In my data, the direction of acceleration components (x, y, z) are represented

问题 Is there a Win32 API call that detects the current Hardware Acceleration level of a user's system? I have no need to change the setting, but I'd like to scale back the level of detail for my OpenGL display if hardware acceleration is disabled. 回答1: From the FAQ: How do I know my program is using hardware acceleration on a Wintel card? If you are using the Win32 interface (as opposed to GLUT), call DescribePixelFormat() and check the returned dwFlags bitfield. If PFD_GENERIC_ACCELERATED is
