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); }

@Overridepublic void surfaceChanged(SurfaceHolder arg0, int arg1, int arg2, int arg3) {// TODO Auto-generated method stub<pre name="code" class="html">                setCameraDisplayOrientation(this,0,camera)

}
