Enable and disable auto rotate programmatically?

Question

There are a lot of cool widgets out there that will enable and disable auto rotate on your phone. Disabling it turns it off across all apps on the phone.

Any ideas

Answer 1

Always use user specified screen orientation, this will apply whatever orientation user has choose and will not rotate screen if its disabled.

activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_USER);

Answer 2

You have to fix it using following code inside onCreate() Function. Working...

setRequestedOrientation (ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

Answer 3

This should do the trick for you:

    import android.provider.Settings;
    public static void setAutoOrientationEnabled(Context context, boolean enabled)
    {
          Settings.System.putInt( context.getContentResolver(), Settings.System.ACCELEROMETER_ROTATION, enabled ? 1 : 0);
    }

Add permission to the AndroidManifest.xml

<uses-permission android:name="android.permission.WRITE_SETTINGS" />

You can find the documentation here

Answer 4

This is my impementation for this problem. I had to implement a button which had the same function that the lockbutton from the settings menu.

you can use the setRotationScreenFromSettings to solve your issue

public static boolean getRotationScreenFromSettingsIsEnabled(Context context)
{

    int result = 0;
    try
    {
        result = Settings.System.getInt(context.getContentResolver(), Settings.System.ACCELEROMETER_ROTATION);
    }
    catch (Settings.SettingNotFoundException e)
    {
        e.printStackTrace();
    }

    return result == 1;
}



public static void setRotationScreenFromSettings(Context context, boolean enabled)
{
    try
    {
        if (Settings.System.getInt(context.getContentResolver(), Settings.System.ACCELEROMETER_ROTATION) == 1)
        {
            Display defaultDisplay = ((WindowManager) context.getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay();
            Settings.System.putInt(context.getContentResolver(), Settings.System.USER_ROTATION, defaultDisplay.getRotation());
            Settings.System.putInt(context.getContentResolver(), Settings.System.ACCELEROMETER_ROTATION, 0);
        }
        else
        {
            Settings.System.putInt(context.getContentResolver(), Settings.System.ACCELEROMETER_ROTATION, 1);
        }

        Settings.System.putInt(context.getContentResolver(), Settings.System.ACCELEROMETER_ROTATION, enabled ? 1 : 0);

    }
    catch (Settings.SettingNotFoundException e)
    {
        e.printStackTrace();
    }
}

 private void regirsterLockScreenOrientationChangedListner()
{
    ContentObserver rotationObserver = new ContentObserver(new Handler())
    {
        @Override
        public void onChange(boolean selfChange)
        {
            refreshLockScreenOrientationBtn();
        }
    };

    context.getContentResolver().registerContentObserver(Settings.System.getUriFor(Settings.System.ACCELEROMETER_ROTATION),
            true, rotationObserver);
}`

Add permission to the AndroidManifest.xml

<uses-permission android:name="android.permission.WRITE_SETTINGS" />
