Spinner popup dialog not adjusting its width on screen rotation

Question

I am using a Spinner with android:spinnerMode="dropdown". I have also set android:configChanges="orientation|keyboardHidden|screenSize" to prevent my Activity to get recreated. when I am in Landscape mode and click on Spinner it pops below the Spinner and have the width same as Spinner button, now when I rotate the screen to portrait mode the Spinner button width get reduced according to the screen size but the pop up dialog does not reduce its width accordingly.

Portrait mode screen:

LAndscape Mode Screen

I thought of closing the pop up and reopen it on screen orientation but I didn't found any way to close the pop up dialog.

Answer 1

On the onConfigurationChanged() method call to spinner.invalidate();
