How do you create an app that only allows horizontal orientation?

问题

I'm currently creating a side-scroller style game for my final year project for my degree.

I'm just wondering how you make the menu designed for when the phone is in horizontal orientation display, even when the phone is held in it's vertical orientation?

i.e. I want the user to know that the game has to be played with the phone in it's horizontal orientation and want the menu's to only display in the horizontal orientation.

Many thanks in advance.

Add the following attribute to your activity in your AndroidManifest.xml:

android:screenOrientation="landscape"

Well, I didn't get your question right, but if you are defining your menu via xml

create a new folder in your res folder named

for layout changes:

layout_land

for horizontal specific menu:

 xml-land

for horizontal specific drawables:

drawable-land

and define your menu,layout and drawable changes there.

Further you can tell android framework that you want to handle rotation changes: by adding to your manifest(AndroidManifest.xml) activity child

android:configChanges="keyboardHidden|orientation"
android:screenOrientation="landscape"

Comment exactly what you want.

Cheers!
