screen

问题 I'm trying to figure out how to fix the orientation problem on webview. Basically every time the user changes the orientation on the device the program goes white and reloads the entire page. This just takes to long. I'd like it to work like every other program that simply adjusts the page size to fit the orientation.I've tried reading other articles on the subject, but when I implement their solution it doesn't seem to fix the problem. Here is my current code. package testdev.HelloWebApp;

问题 I am trying to find the width and height of the screen but none of the ways I have tried will work in the class I created, my code is below. Does anyone know how to find it? I cannot use the way I am trying below because .getWidth() is deprecated? public class Crate { public int acrossCrate; public int upDownCrate; Context theContext; WindowManager wm = (WindowManager)theContext.getSystemService(Context.WINDOW_SERVICE); Display display = wm.getDefaultDisplay(); int width = display.getWidth();

问题 Now i do try again. I want to change the screen brightness. I've Tried: WindowManager.LayoutParams layoutParams = getWindow().getAttributes(); layoutParams.screenBrightness = 0.5F; // set 50% brightness getWindow().setAttributes(layoutParams); and seems to work in activity but when I am in service i get that getWindow() compile error. 回答1: A service cannot change the screen brightness that way. A service does not have a user interface, so it does not have Window . You can try to change the

问题 I have found two ways on keeping the screen on: First one is simpler: getWindow().setFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON, WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON); Second one is using a wakelock and requiring an extra permission: PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE); wl = pm.newWakeLock(PowerManager.FULL_WAKE_LOCK, "DoNotDimScreen"); Is there any real difference between this two methods apart from the second one being more

问题 I'm using GetObject with a workbook path to either create a new or grab an existing Excel instance. If it's grabbing an existing user-created instance, the application window is visible; if the workbook path in question is closed, it will open and hide, but not before it flickers on the screen. Application.ScreenUpdating does not help with this. I don't think I can use the Win32Api call LockWindowUpdate, because I don't know whether I'm getting or creating before the file is open. Is there

问题 I am using Tkinter to create a login screen here. At the moment, the "keep me logged in" button at the bottom is redundant and will remain so. What I want to do is use this code: from tkinter import * root = Tk() label_1 = Label(root, text="Username") label_2 = Label(root, text="Password") entry_1 = Entry(root) entry_2 = Entry(root) label_1.grid(row=0, sticky=E) label_2.grid(row=1, sticky=E) entry_1.grid(row=0, column=1) entry_2.grid(row=1, column=1) checkbox = Checkbutton(root, text="Keep me

问题 I have a Qt application which needs to be loaded on mobile devices of different screen sizes. How do I make it autofit to the mobile device's screen size? 回答1: If you want your application's main window to occupy the whole screen as soon as it starts, use QWidget::showMaximized, e.g. int main(int argc, char **argv) { QApplication app(argc, argv); MyMainWidget widget; widget.showMaximized(); return app.exec(); } Note that showMaximized is a convenience function which internally calls the

问题 I'm new on Swift Programming, and I'm trying to build an app that I can get the coordinates of the center of the view with MapKit and Swift 2. I already can get the current location, but I need if I move on the map, the location set to the new point which will be the center of the screen. Can you help me with this please?.

问题 I want to know: how to clean screen on an UNIX-based system? I searched on the Internet, but I've just found how to do it on Windows: system("CLS") I don't want exactly to clean cpmpletely the screen, but I want to open a "new page", such as in the NANO and VI editors. Thanks 回答1: Maybe you can make use of escape codes #include <stdio.h> #define clear() printf("\033[H\033[J") int main(void) { clear(); return 0; } But keep in mind that this method is not compatible with all terminals 回答2: You
