How could I make the SurfaceView and Button have a different orientation in a Activity

I hava a simple program about video recording . I use the surfaceView to show the preview screen. and I also w开发者_StackOverflowant to put some buttons on the screen.

I put all the component mentioned above into a XML file which is "ipcam.xml"

I use MediaRecorder , SurfaceView , SurfaceHolder to complete this program because the preview screen does not orientate correctly when I rotate my phone. so I use "setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);" but , the button in the program is always in LANDSCAPE direction . it will not auto change direction when I rotate my phone , but the preview is ok!!

so is there anyway to solve this problem.

Thank you all very much in advance.

you can see this picture , I put my phone in vertical direction the preview screen seems OK but the button is in horizontal direction , i don't want it.

Try this:

<activity android:name=".MyActivity"
      android:label="@string/app_title"
      android:screenOrientation="landscape"
      android:configChanges="keyboardHidden|orientation">
</activity>

Did you specify android:configChanges="keyboardHidden|orientation" on your activity's configuration in the manifest.xml?
