Make sure all of your parent views have autoresizesSubviews = YES. You may need to do this in code if you haven’t set springs and struts in IB for all of your views. Quoting the Interface Builder User’s Guide: Important: In a Cocoa nib file, if you do not set any springs or struts for … Read more
Ok, after trying to use the Android API and not being able to do what I need, I implemented my own algorithm and actually it wasn’t that complicated: I used a OrientationEventListener, and calculated if the orientation is in the 4 orientation points (in my code I only detect LANDSCAPE_RIGHT and PORTRAIT_UP: orientationListener = new … Read more
I ended up using the following solution: private int getScreenOrientation() { int rotation = getWindowManager().getDefaultDisplay().getRotation(); DisplayMetrics dm = new DisplayMetrics(); getWindowManager().getDefaultDisplay().getMetrics(dm); int width = dm.widthPixels; int height = dm.heightPixels; int orientation; // if the device’s natural orientation is portrait: if ((rotation == Surface.ROTATION_0 || rotation == Surface.ROTATION_180) && height > width || (rotation == Surface.ROTATION_90 … Read more
Please turn off config changes as a last resort. Your app must work correctly when this happens. If you turn off the orientation config change because it breaks, your app will still break in other and some times more subtle way. Allowing the activity to be restarted due to an orientation config change is a … Read more
First import the services package: import ‘package:flutter/services.dart’; This will give you access to the SystemChrome class, which “Controls specific aspects of the operating system’s graphical interface and how it interacts with the application.” When you load the Widget, do something like this: @override void initState(){ super.initState(); SystemChrome.setPreferredOrientations([ DeviceOrientation.landscapeRight, DeviceOrientation.landscapeLeft, ]); } then when I leave … Read more
EDIT: This is happening because Apple has changed the way of managing the Orientation of UIViewController. In iOS6 orientation handles differently. In iOS6 shouldAutorotateToInterfaceOrientation method is deprecated. View controllers (such as UINavigationController) do not consult their children to determine whether they should autorotate. By default, an app and a view controller’s supported interface orientations are … Read more
As explained by Chris in his self-answer, calling setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_NOSENSOR); and then setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR); really works like charm… on real devices ! Don’t think that it’s broken when testing on the emulator, the ctrl+F11 shortcut ALWAYS change the screen orientation, without emulating sensors moves. EDIT: this was not the best possible answer. As explained in the comments, … Read more
Here’s a good way using resources and size qualifiers. Put this bool resource in res/values as bools.xml or whatever (file names don’t matter here): <?xml version=”1.0″ encoding=”utf-8″?> <resources> <bool name=”portrait_only”>true</bool> </resources> Put this one in res/values-sw600dp and res/values-xlarge: <?xml version=”1.0″ encoding=”utf-8″?> <resources> <bool name=”portrait_only”>false</bool> </resources> See this supplemental answer for help adding these directories and … Read more
Yes it is implementable! ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE); ActivityInfo.SCREEN_ORIENTATION_PORTRAIT setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); ActivityInfo http://developer.android.com/reference/android/content/pm/ActivityInfo.html Refer the link: Button buttonSetPortrait = (Button)findViewById(R.id.setPortrait); Button buttonSetLandscape = (Button)findViewById(R.id.setLandscape); buttonSetPortrait.setOnClickListener(new Button.OnClickListener(){ @Override public void onClick(View arg0) { setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); } }); buttonSetLandscape.setOnClickListener(new Button.OnClickListener(){ @Override public void onClick(View arg0) { setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE); } }); http://android-er.blogspot.in/2011/08/set-screen-orientation-programmatically.html
I think this is a much simpler version. Bundle is a built-in type which implements Parcelable public class CustomView extends View { private int stuff; // stuff @Override public Parcelable onSaveInstanceState() { Bundle bundle = new Bundle(); bundle.putParcelable(“superState”, super.onSaveInstanceState()); bundle.putInt(“stuff”, this.stuff); // … save stuff return bundle; } @Override public void onRestoreInstanceState(Parcelable state) { if … Read more
