Android设置方向

检查方向

@Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);

// Checks the orientation of the screen
if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) {
    Toast.makeText(this, "landscape", Toast.LENGTH_SHORT).show();
} else if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT){
    Toast.makeText(this, "portrait", Toast.LENGTH_SHORT).show();
}
}

public class OrientationUtils {
private OrientationUtils() {}

/** Locks the device window in landscape mode. */
public static void lockOrientationLandscape(Activity activity) {
    activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
}

/** Locks the device window in portrait mode. */
public static void lockOrientationPortrait(Activity activity) {
    activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
}

/** Allows user to freely use portrait or landscape mode. */
public static void unlockOrientation(Activity activity) {
    activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_UNSPECIFIED);
}

}
