How do I lock screen orientation for phone, but not for tablet? (Android)

由 北战南征 提交于 2019-12-18 19:06:20
问题 I have been working on a Android project, that is intended to be compatible with both the Android phones and tablets. On the tablet the app is working great and looks good too. However, on the phone we have been running into issues both programmatically and layout wise (working with a 10.1 inch screen is a lot easier than a 4 inch screen). To solve some of these problems we have decided to deactivate screen orientation but only for the phone version, atleast temporarily. The question is

问题 I want to add an extra div if the ipad is in landscape mode. Is there some sort of if statement that could find this out? Thanks 回答1: jQTouch checks it like so: orientation = Math.abs(window.orientation) == 90 ? 'landscape' : 'portrait'; http://github.com/senchalabs/jQTouch/blob/master/jqtouch/jqtouch.js You can also listen to onorientationchange events See previous answer: Detect rotation of Android phone in the browser with JavaScript 回答2: You could do a simple check for the width of the

How to convert & rotate raw NV21 array image (android.media.Image) from front cam portrait mode in onImageAvailable (android Camera2)?

由 左心房为你撑大大i 提交于 2019-12-18 03:46:48
问题 Note: All info in my post only goes for Samsung Galaxy S7 device. I do not know how emulators and other devices behave. In onImageAvailable I convert continuously each image to a NV21 byte array and forward it to an API expecting raw NV21 format. This is how I initialize the image reader and receive the images: private void openCamera() { ... mImageReader = ImageReader.newInstance(WIDTH, HEIGHT, ImageFormat.YUV_420_888, 1); // only 1 for best performance mImageReader

Android - Camera preview is sideways

问题 I am using a Preview to display what the camera see's on the screen. I can get everything working fine, surface created, surface set and the surface is displayed. However it always displays the picture at an incorrect 90 degree angle in portrait mode. Such as in the picture: I am aware that using the following code will set the picture straight: setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE); However I have the Preview within an Activity that has other elements in it and

Best practice to support portrait and landscape views in a UINavigationController

由 余生颓废 提交于 2019-12-12 11:01:12
问题 I searched high and low and I'm not sure what I came out with is the best way of dealing with this (though it seems the only one). According to Want to use muliple nibs for different iphone interface orientations I implemented the relevant methods, and everything seems to work fine. Unfortunately I have to deal with a UINavigationController, and each page has to support both portrait and landscape modes, and reproduce the same functionalities in both modes. That means that If a user at some

How to enable only portrait and reverse portrait in phones, “sensorPortrait” not working on phones?

由 ∥☆過路亽．° 提交于 2019-12-12 09:37:49
问题 I cant figure out why setting "sensorPortrait" attribute in manifest for an activity doesn't work to allow the activity to go into reverse portrait. This is how I set in manifest <activity android:name=".MainActivty" android:label="Testing" android:screenOrientation="sensorPortrait" android:windowSoftInputMode="stateHidden" android:configChanges="orientation"> </activity> The above code is not working for me to get both reversePortrait and portrait on Moto E(4.4.4) or Galaxy S3(4.3), but I

Universal app and landscape orientation for iPad

由 爱⌒轻易说出口 提交于 2019-12-12 01:06:37
问题 I want to design a universal app that I'd want to support just portrait orientation. It's weird because Xcode allows you to select portrait orientation only in the target's Deployment Info settings (and in Info.plist), but reading the iOS Human Interface Guidelines, in the section regarding the launch images, I've found this: You must provide at least one launch image. Typically, an iPhone app includes at least one launch image in portrait orientation; an iPad app includes at least one launch
