安卓相机的问题

我正在 android 中构建一个使用相机的应用程序。我已经构建了自己的相机，但问题是，一旦我以这种方式打开相机：

 public void surfaceCreated(SurfaceHolder holder) {
        Log.e(TAG, "surfaceCreated");
        mCamera = Camera.open();

    }

当手机处于 状态时，我的预览和拍摄的照片都会旋转 90 度>纵向模式，当手机转到横向模式时，一切看起来都很棒。有谁知道如何解决这个问题。

谢谢你！

I'm building an application in android which uses the camera.I have built my own camera but the problem is that once I open my camera this way:

 public void surfaceCreated(SurfaceHolder holder) {
        Log.e(TAG, "surfaceCreated");
        mCamera = Camera.open();

    }

Both my preview and the picture taken are rotated 90 degrees when the phone is in portrait mode, when the phone is turned in the landscape mode everything looks great.Does anyone know how could this be solved.

Thank you!

Camara.Parameters 的 setRotation(introtation) 是你的朋友。

编辑：

您是否在文档中看到了参考代码：

public void public void onOrientationChanged(int orientation) {
     if (orientation == ORIENTATION_UNKNOWN) return;
     android.hardware.Camera.CameraInfo info =
            new android.hardware.Camera.CameraInfo();
     android.hardware.Camera.getCameraInfo(cameraId, info);
     orientation = (orientation + 45) / 90 * 90;
     int rotation = 0;
     if (info.facing == CameraInfo.CAMERA_FACING_FRONT) {
         rotation = (info.orientation - orientation + 360) % 360;
     } else {  // back-facing camera
         rotation = (info.orientation + orientation) % 360;
     }
     mParameters.setRotation(rotation);
 }

setRotation(int rotation) of Camara.Parameters is your friend here.

Edit:

Did you see the reference code in the docs :

public void public void onOrientationChanged(int orientation) {
     if (orientation == ORIENTATION_UNKNOWN) return;
     android.hardware.Camera.CameraInfo info =
            new android.hardware.Camera.CameraInfo();
     android.hardware.Camera.getCameraInfo(cameraId, info);
     orientation = (orientation + 45) / 90 * 90;
     int rotation = 0;
     if (info.facing == CameraInfo.CAMERA_FACING_FRONT) {
         rotation = (info.orientation - orientation + 360) % 360;
     } else {  // back-facing camera
         rotation = (info.orientation + orientation) % 360;
     }
     mParameters.setRotation(rotation);
 }
