orientation

问题 I have this code in my application: LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(WRAP_CONTENT, WRAP_CONTENT); and I just want to set the orientation of the LinearLayout to vertical. The equivalent in XML is: android:orientation="vertical" How can I do it in the code, without XML? 回答1: You can't change LinearLayout 's orientation using its LayoutParams . It can be done only with a LinearLayout object. LinearLayout layout = /* ... */; layout.setOrientation(LinearLayout

问题 I am using a TableLayout with TableRows as my main activity. Inside the TableLayout is a Radio Group containing 2 Radio Buttons inside the activity (the Radio Group being inside a table row). I want to be able to align the rightmost radio button to the right edge screen, so the "gap" is between the left radio button and right button (instead of after the right radio button). i.e. So instead of having | (x) (x) gap | I will have |(x) gap (x)| where (x) are the Radio Buttons and | are the edges

问题 The Sensor Fusion video looks great, but there's no code: http://www.youtube.com/watch?v=C7JQ7Rpwn2k&feature=player_detailpage#t=1315s Here is my code which just uses accelerometer and compass. I also use a Kalman filter on the 3 orientation values, but that's too much code to show here. Ultimately, this works ok, but the result is either too jittery or too laggy depending on what I do with the results and how low I make the filtering factors. /** Just accelerometer and magnetic sensors */

问题 There're 3 ways to get current interface orientation that I know of: self.interfaceOrientation [[UIApplication sharedApplication] statusBarOrientation] [[UIDevice currentDevice] orientation] What are the differences among them? 回答1: self.interfaceOrientation returns UIInterfaceOrientation, current orientation of the interface. It is a property in UIViewController, you can access to this one only in UIViewController classes. [[UIApplication sharedApplication] statusBarOrientation] returns

问题 I have created a layout for an activity. The layout contains some image buttons and text views. The problem is that when I am setting the orientation of my device to portrait, its working fine, but when I am changing the orientation to landscape, the layout is giving unexpected results. Here is my layout file : <ScrollView xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:fillViewport="true" android

问题 My app has navigation bar, where 1st screen returns YES to orientation, the second one is set to some orientation basing on what user choose in 1st screen. After going back to 1st screen from 2nd one, if user had device in hand in portrait but interface was in landscape, 1st screen is set to landscape. This happens because of (BOOL)shouldAutorotateToInterfaceOrientation(UIInterfaceOrientation)interfaceOrientation Is called only after changing device orientation. I want to check what is device

问题 I've implemented the proper functions, but they don't get triggered? I've tried several solutions here on StackOverFlow, but none of them work. I've tried adding the view to a UINavigationController, also doesn't work. FakeIDDetailViewController.h: @interface FakeIDDetailViewController : UIViewController @end FakeIDDetailViewController.m: @interface FakeIDDetailViewController () -(BOOL)shouldAutorotate { return NO; } - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation

问题 I have a situation, I have created two different nibs, one in Portrait Mode and other in Landscape mode. I had lots of designs in the view so, i had to opt for two different nibs. Now, I want to toggle the nibs as the interface rotates in the common viewController so that I can retain the filled values and the state of the controls I have in the view. Right now I am using - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { // Override to allow

问题 I have created two .xib file one for portrait mode and other for landscape mode, on each rotation i want to load respective .xib file, Here is my code snippet, ViewAppDelegate.m class - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; if ([UIApplication sharedApplication].statusBarOrientation==UIInterfaceOrientationPortrait | [UIApplication

问题 With Which Sensor I Can Detect when device is moving to a direction In Absolute Coordinate(for example moving to +x or -x). I need accurate data,so i cannot use GPS . the Complete Task is to plot in paint(in computer) with android device sensors and this part of task in unknown for me. 回答1: I'm a little confused about what you're asking. Do you want to put a device in your pocket and walk around, and make a plot of everywhere you walked? Or do you want to wave the device around in your hand
