You can try with the sample below...

if (getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE) {
    // You can set the value initially by
    // ActivityInfo.SCREEN_ORIENTATION_UNSPECIFIED. Once set it
    // retains it's value. The View will be rendered in the specified
    // orientation using the code below.
    setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
}
