有部分手机的影像是倒立的，如何解决这个问题呢？ 请看下面              public static void setCameraDisplayOrientation(Activity activity,               int cameraId, android.hardware.Camera camera) {           android.hardware.Camera.CameraInfo info =                   new android.hardware.Camera.CameraInfo();           android.hardware.Camera.getCameraInfo(cameraId, info);           int rotation = activity.getWindowManager().getDefaultDisplay()                   .getRotation();           int degrees = 0;           switch (rotation) {               case Surface.ROTATION_0: degrees = 0; break;               case Surface.ROTATION_90: degrees = 90; break;               case Surface.ROTATION_180: degrees = 180; break;               case Surface.ROTATION_270: degrees = 270; break;           }                   int result;           if (info.facing == Camera.CameraInfo.CAMERA_FACING_FRONT) {               result = (info.orientation + degrees) % 360;               result = (360 - result) % 360;  // compensate the mirror           } else {  // back-facing               result = (info.orientation - degrees + 360) % 360;           }           camera.setDisplayOrientation(result);       }       @Override          public void surfaceChanged(SurfaceHolder arg0, int arg1, int arg2, int arg3) {              // TODO Auto-generated method stub                           setCameraDisplayOrientation(this,0,camera)            }
