How to stop changing the orientation when a progress bar is spinning in android

Question

I have a Registration screen where user enters all the registration details and when user clicks on the "Register" button i am showing the progress bar(Progress bar begins to spin) and then takes the user to the home screen.If the user rotates the phone when progress bar is spinning, the progress bar gets dismissed.I want the orientation not to change from potrait to landscape and vice versa,when a progress bar is visible(meaning it is spinning).How to stop the orientation change when progress bar is spinning?Any help would be appreciated.

Answer 1

This is happening because when screen orientation rotates the Activity gets re-started. In this case you can add configChanges attribute in your tag in the AndroidManifest file to stop the re-creation of the Activity.

<activity android:name=".Activity_name"
          android:configChanges="orientation|keyboardHidden">

By, this your orientation can change will the progress bar is working and also it won't stop though the orientation changes.

UPDATE

@Override
    public void onConfigurationChanged(Configuration newConfig) {
        super.onConfigurationChanged(newConfig);
        if(newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE){
            setContentView(R.layout.login_landscape);
        }
        else if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT) {
            setContentView(R.layout.login);         
        }
    }

Answer 2

As explained here, 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.

And I think you are not able to handle progressbar on screen rotation. Am I right?

So you need not to stop the rotation for this solution. You should handle the progress bar. Here are some tutorials, which are useful for this purpose ..
