捕获的照片显示方向正在改变机器人 [英] Captured Photo orientation is changing in android

问题描述

我'上点击一个按钮，打开相机应用。和显示拍摄的照片中下一个活动。但所捕获的照片旋转90度。当我在我拍摄后的视图显示图像，它的方向是永远的风景。为什么照片没有显示在画像作为当照片拍摄在纵向模式是？

按钮的onClick：

 意向书我=新的意图（android.provider.MediaStore.ACTION_IM​​AGE_CAPTURE）;
i.putExtra（android.provider.MediaStore.EXTRA_OUTPUT，Uri.fromFile（新文件（APP_DIR +/ latest.png）））;
startActivityForResult（ⅰ，CAPTURE_PHOTO_CONSTANT）;
 

里面onActvityresult：

  BMP = BitmapFactory.de codeFILE（APP_DIR +/ latest.png）;
startActivity（新意图（这一点，DisplayActivity.class））;
 

显示拍摄的照片：

  photoViewRelativeLayout.setBackgroundDrawable（新BitmapDrawable（getResources（），CaptureActivity.bmp））;
 

解决方案

我有同样的问题大多与三星handsets.Apparently三星手机设置的EXIF方向标签，而不是使用BitmapFactory不旋转个人pixels.Reading位图支持此tag.What我找到了解决这个问题是在activity.Which检查具有URI从相机相关联的捕捉到的图像的取向onActivityResult方法使用ExifInterface

  INT旋转= 0;
                        尝试 {
                            getContentResolver（）有NotifyChange（imageUri，空）。
                            文件镜像文件=新的文件（的ImagePath）;
                            ExifInterface EXIF​​ =新ExifInterface（
                                    imageFile.getAbsolutePath（））;
                            INT方向= exif.getAttributeInt（
                                    ExifInterface.TAG_ORIENTATION，
                                    ExifInterface.ORIENTATION_NORMAL）;

                            开关（方向）{
                            案例ExifInterface.ORIENTATION_ROTATE_270：
                                旋转= 270;
                                打破;
                            案例ExifInterface.ORIENTATION_ROTATE_180：
                                旋转= 180;
                                打破;
                            案例ExifInterface.ORIENTATION_ROTATE_90：
                                旋转= 90;
                                打破;
                            }
                            Log.v（Common.TAG，的Exif方向：+方向）;
                        }赶上（例外五）{
                            e.printStackTrace（）;
                        }

                        / ******图像旋转**** /
                        字模=新的Matrix（）;
                        matrix.postRotate（方向）;
                        位图裁剪= Bitmap.createBitmap（缩放，X，Y，宽度，高度，矩阵，真）;
 

I'am opening camera app on click of a button. And displaying the captured photo in next activity. But the captured photo is rotating by 90 degrees. When I display the image in a view after I capture it, it's orientation is always landscape. Why is the photo not being shown in portrait as is when the photo is taken in portrait mode?

onClick of a button :

Intent i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
i.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, Uri.fromFile(new File(APP_DIR+"/latest.png")));       
startActivityForResult(i, CAPTURE_PHOTO_CONSTANT);

Inside onActvityresult:

bmp = BitmapFactory.decodeFile(APP_DIR+"/latest.png");
startActivity(new Intent(this, DisplayActivity.class));

Displaying captured photo:

photoViewRelativeLayout.setBackgroundDrawable(new BitmapDrawable(getResources(), CaptureActivity.bmp));

解决方案

I had the same problem mostly with the Samsung handsets.Apparently Samsung phones set the EXIF orientation tag, rather than rotating individual pixels.Reading the Bitmap using BitmapFactory does not support this tag.What i found the solution to this problem was using ExifInterface in onActivityResult method of the activity.Which checks for orientation associated with URI of the captured image from the camera.

                        int rotate = 0;
                        try {
                            getContentResolver().notifyChange(imageUri, null);
                            File imageFile = new File(imagePath);
                            ExifInterface exif = new ExifInterface(
                                    imageFile.getAbsolutePath());
                            int orientation = exif.getAttributeInt(
                                    ExifInterface.TAG_ORIENTATION,
                                    ExifInterface.ORIENTATION_NORMAL);

                            switch (orientation) {
                            case ExifInterface.ORIENTATION_ROTATE_270:
                                rotate = 270;
                                break;
                            case ExifInterface.ORIENTATION_ROTATE_180:
                                rotate = 180;
                                break;
                            case ExifInterface.ORIENTATION_ROTATE_90:
                                rotate = 90;
                                break;
                            }
                            Log.v(Common.TAG, "Exif orientation: " + orientation);
                        } catch (Exception e) {
                            e.printStackTrace();
                        }

                        /****** Image rotation ****/
                        Matrix matrix = new Matrix();
                        matrix.postRotate(orientation);
                        Bitmap cropped = Bitmap.createBitmap(scaled, x, y, width, height, matrix, true);
