處理豎屏拍攝圖片上傳後顯示為橫屏的問題
picPath為圖片路徑
/** * 照片拍攝成功 */ public void takePhotoSuccess() { Bitmap bitmap = BitmapUtil.createBitmapWithFile(picPath, 640); BitmapFactory.Options bitmapOptions = new BitmapFactory.Options(); bitmapOptions.inSampleSize = 8; int degree = readPictureDegree(new File(picPath).getAbsolutePath()); Bitmap cameraBitmap = BitmapFactory.decodeFile(picPath, bitmapOptions); bitmap = cameraBitmap; bitmap = rotaingImageView(degree, bitmap); BitmapUtil.createPictureWithBitmap(picPath, bitmap, 100); if (!bitmap.isRecycled()) { bitmap.recycle(); } sendFile(1, new File(picPath)); } /** * 旋轉圖片 * * @param angle * @param bitmap * @return Bitmap */ public static Bitmap rotaingImageView(int angle, Bitmap bitmap) { //旋轉圖片 動作 Matrix matrix = new Matrix(); ; matrix.postRotate(angle); System.out.println("angle2=" + angle); // 建立新的圖片 Bitmap resizedBitmap = Bitmap.createBitmap(bitmap, 0, 0, bitmap.getWidth(), bitmap.getHeight(), matrix, true); return resizedBitmap; } /** * 讀取圖片屬性:旋轉的角度 * * @param path 圖片絕對路徑 * @return degree旋轉的角度 */ public static int readPictureDegree(String path) { int degree = 0; try { ExifInterface exifInterface = new ExifInterface(path); int orientation = exifInterface.getAttributeInt(ExifInterface.TAG_ORIENTATION, ExifInterface.ORIENTATION_NORMAL); switch (orientation) { case ExifInterface.ORIENTATION_ROTATE_90: degree = 90; break; case ExifInterface.ORIENTATION_ROTATE_180: degree = 180; break; case ExifInterface.ORIENTATION_ROTATE_270: degree = 270; break; } } catch (IOException e) { e.printStackTrace(); } return degree; }
