I have an activity which I have defined to keep in portrait position.
However I would still like to change things (slightly) when the screen is rotated, what is the best way of doing this? I notice onConfigurationChanged is still called, but this still reports portrait mode.
I want to keep the notification bar etc in the same position if possible.

On my htc i was looking through display, i see g sensor calibration and i perform this calibration and after i do so the screen seems to have a delay when switch from the horizontal position to the vertical position. its weird because when i switch to the phone horizontally it switch normally and responds fast. but when i switch back to vertically it takes almost 7 seconds to actually switch back, sometimes it switch within 2 or 3 secs but never as quick as switching horizontally.

If you're already updated, shut down and repower (soft reboot) should do the trick. I actually updated my phone and after it started to do this. I restarted the phone plenty of times i even took the battery out for 30 seconds. It only does it when im texting on the browser, basically everything but the camera. He camera screen rotation is perfect. I even rooted the phone but i havent figured out how to use the root to fix the problem. Should i do a firmware update? Because i just did the htc software update.
I must be overlooking something real simple here, but i think i'm trying to do something fairly basic.. Simply retain the scrollbar position of a ScrollView on orientation change...
Here is the code for my onSaveInstanceState and onRestoreInstanceState.. sView is the container for the ScrollView layout. Within my scrollview is a linearlayout with a lot of textviews.
CODE:............
If I set a Toast with the values of sViewX and sViewY on the Restore, the values are kept and correct.
I just tried to do a sView.scrollTo(0,150); in my onCreate.. just to see if that would open the activity at 150px down, and it didn't. I think my issue has to do with the .scrollTo method.

Is there a standard pattern for handling a running AsyncTask with screen rotation? My AsyncTask runs for about 10 seconds. I could call AsyncTask.cancel in the Activity's onDestroy method and restart the task in onCreate but that would waste cycles, bandwidth, and user time. I'm guessing there is a better way.
View 1 Replies View RelatedIn my Android app I have 2 layouts, one for portrait and one for landscape.
In both layouts I have a TextView that the user can change by clicking on, by default it reads 'ON'
If the user presses it then it changes to 'OFF' All well and good.
However if it's set to OFF and the screen is rotated the text view resets to ON. How can I stop this from happening?

Step #2: Manually associate your activity with the task in its constructor
Step #3: Return the task object from onRetainNonConfigurationInstance() of your activity
Step #4: In onCreate() of your activity, check getLastNonConfigurationInstance(), and if it is not null, associate your new activity instance with the task via a setter
Step #5: Use the activity within onPostExecute()

View 3 Replies View RelatedHow to save my instance state or how to deal with my activity getting destroyed during screen rotation.
There seem to be a lot of possibilities but I haven't figured out which one works best for retrieving results of an AsyncTask.
I have some AsyncTasks that are simply started again and call the isFinishing() method of the activity and if the activity is finishing they wont update anything.
The problem is that I have one Task that does a request to a web service that can fail or succeed and restarting the task would result in a financial loss for the user.
How would you solve this? What are the advantages or disadvantages of the possible solutions?

View 1 Replies View RelatedI've got an app that I don't want to auto-rotate. Currently, I've got it setup so that it is always in portrait mode. However, I'd like to add a setting to my preferences where the user can choose either portrait or landscape mode. Is there a way to force screen rotation? Or, could I perhaps make two different layout XML files, one for portrait and one for landscape, and programmatically choose which to use?
View 9 Replies View RelatedI have come across some very unexpected (and incredibly frustrating) functionality while trying to restore the state of a list of CheckBoxes after a screen rotation. I figured I first would try to give a textual explanation without the code, in case someone is able to determine a solution without all the gory details. If anyone needs more details I can post the code.
I have a scrolling list of complex Views that contain CheckBoxes. I have been unsuccessful in restoring the state of these check boxes after a screen rotation. I have implemented onSaveInstanceState and have successfully transfered the list of selected check boxes to the onCreate method. This is handled by passing a long[] of database ids to the Bundle.
In onCreate() I check the Bundle for the array of ids. If the array is there I use it to determine which check boxes to check when the list is being built. I have created a number of test methods and have confirmed that the check boxes are being set correctly, based on the id array. As a last check I am checking the states of all check boxes at the very end of onCreate(). Everything looks good... unless I rotate the screen.
When I rotate the screen, one of two things happens: 1) If any number of the check boxes are selected, except for the last one, all check boxes are off after a rotation. 2) If the last check box is checked before rotation, then all check boxes are checked after rotation.
Like I said, I check the state of the boxes at the very end of my onCreate(). The thing is, the state of the boxes at the end of onCreate is correct based on what I selected before the rotation. However, the state of the boxes on the screen does not reflect this.
In addition, I have implemented each check box's setOnCheckChangedListener() and I have confirmed that my check boxes' state's are being altered after my onCreate method returns.
Why would the state of my check boxes change after my onCreate method returns?
I have been trying to degub this for a couple days now. After I found that my check boxes were apparently changing somewhere outside my own code I figured it was time to ask around.

View 2 Replies View RelatedMy 2.1 rom only went into landscape mode when I turned the phone counter-clockwise. I have found that since updating to 2.2, the screen will go into landscape if I go either direction!

View 11 Replies View RelatedI have an android application that I want to always be running in landscape mode.
I have the following code implemented to keep the app in landscape mode all the time:
inside my activity in the Application Manifest
android:screenOrientation="landscape"
This seems to launch and keep the application in landscape view for the whole duration of the application. Perfect!
However, if I have the app running on my HTC Aria (Android 2.1) and the phone locks, if I unlock the phone, I see the application for probably half a second and it's in portrait orientation and then quickly switches back to landscape mode. It is quite frustrating because all of my views are jumbled around and it looks unprofessional as you can imagine. This happens in both the emulator and on my real phone.
Does anyone know how to stop the application from temporarily rotating when the phone is unlocked?
I have tried overriding onConfigurationChanged() but with no success.
I have also tried putting setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE); into the onResume() but the app still shows as the incorrect orientation for a split second when the phone is unlocked.

View 1 Replies View RelatedI have been trying to keep the context menu when doing a long press / Click to stay on screen when the screen is rotated.Searching around the net, the main answers found are not the best such as add configChanges into the android manifest or use the onRetainNonConfigurationInstance which is depreciated .
Currently I am handling my dialog boxes when on screen and a rotation occurs via savedInstanceState by having my own method to show them again by using a variable to be saved into the bundle and then retrieved.
However the context menu is slightly harder to do as it is registered against the listview I have and this links it together so it knows which row has been selected
I do also have a onitemlongclick method which works along side the contextmenu so I should be able to get the row information from there but it is then how to call it all back afterwards
I was working on implementing a more advanced list view then the standard one they teach you in basic tutorials, and I did find a great tutorial explaining how to create your own Adapter and such not. http://www.softwarepassion.com/android-series-custom-listview-items-a...
I do have a working version of the tutorial and I am currently in the process of changing the list to suit my needs, but there are a few issues I am stumped on. If your run the tutorial code it creates a little progress dialog saying that it is retrieving data. In my application it is going to be fetching data from the internet and storing it in an ArrayList of custom objects. However if I where to rotate the screen the progress dialog pops up again, I have no clue on how to set it up so that when it rotates that it doesn't recreate everything and re-fetch the data and process it again.
View.getLeft() and View.getTop() give the position of the view relative to the parent.
Is there a way to get the absolute screen position of that view?
Either a way to translate those coordinates into screen coordinates to make a call to get the position in screen coordinates.
My Desire; which i have had problem free for 3 months; has just developed a problem with the screen rotation. Initially it wouldn't rotate so i checked that it was set to automatically rotate in the screen and display menu which it was .
I then tried to recalibrate the screen which kind of worked in that it now allows the screen to rotate to landscape if held sideways, but when i put it the right way up, the screen stays landscape.
I have Swype which i thought might be interfering so i removed the program and rebooted but still nothing.
I feel foolish as all get-out, but I have managed to put the screen on my Eris into an animated rotation mode. I.e. instead of snapping from horizontal to vertical, it rocks from side to side for a annoying period of time. I can't find the setting under 'display'
