捕獲某些Android設備上旋轉的相機圖片

Question

在某些設備（Nexus 9，Nexus S等）上，相機會將旋轉的圖片加載到ImageView 。 我試圖用ExifInterface修復它，但沒有成功。 有人對此代碼示例有想法嗎？

編譯的SDK版本是25
最低SDK版本為15

public void capturePhoto(String targetFilename) {
    Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
        startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
    }
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == REQUEST_IMAGE_CAPTURE) {
        Bundle extras = data.getExtras();
        Bitmap imageBitmap = (Bitmap) extras.get("data");
        mImageView.setImageBitmap(imageBitmap);
    }
}
}

Answer 1

使用以下代碼：

@Override
    public void onPictureTaken(byte[] data, Camera camera) {
int rotation = getPhotoRotation();
        rotatePicture(rotation, data);
        savePicture();
        setSafeToTakePhoto(true);
    }

從此處獲取設備的旋轉：

private int getPhotoRotation() {
        int rotation;
        int orientation = mOrientationListener.getRememberedNormalOrientation();
        CameraInfo info = new CameraInfo();
        Camera.getCameraInfo(mCameraID, info);

        if (info.facing == CameraInfo.CAMERA_FACING_FRONT) {
            rotation = (info.orientation - orientation + 360) % 360;
        } else {
            rotation = (info.orientation + orientation) % 360;
        }

        return rotation;
    }
     private int getRememberedNormalOrientation() {
            rememberOrientation();
            return mRememberedNormalOrientation;
        }
     private void rememberOrientation() {
            mRememberedNormalOrientation = mCurrentNormalizedOrientation;
        }

如果您不想識別移動設備旋轉，請使用上述代碼檢測移動設備方向並按設備旋轉保存圖像。
