이미지를 저장하고 경로를 저장하는 방법 sd 카드에서 Android를 잘라 냈습니까?

Question

http://www.londatiga.net/featured-articles/how-to-select-and-crop-image-on-android/에서 자르기 이미지 튜토리얼을 학습했지만 결과 또는 자르기 후에 이미지가 SD 카드에 저장되지 않는 경우 어떻게 수정합니까?

당신이 당신의 onActivityResult를 자른 이미지 비트 맵을 얻는다. Sd 카드에 저장하려면 CROP_FROM_CAMERA 경우에 저장하십시오. 그렇지 않으면 직접 비트 맵을 사용할 수 있습니다.

case CROP_FROM_CAMERA:   
      Bundle extras = data.getExtras(); 

      if (extras != null) {    
       Bitmap photo = extras.getParcelable("data"); 

       mImageView.setImageBitmap(photo); 
       String root = Environment.getExternalStorageDirectory().toString(); 
       File myDir = new File(root + "/saved_images");  
       myDir.mkdirs(); 
       Random generator = new Random(); 
       int n = 10000; 
       n = generator.nextInt(n); 
       String fname = "Image-"+ n +".jpg"; 
       File file = new File (myDir, fname); 
       if (file.exists()) file.delete(); 
       try { 
        FileOutputStream out = new FileOutputStream(file); 
        photo.compress(Bitmap.CompressFormat.JPEG, 90, out); 
        out.flush(); 
        out.close(); 
       } catch (Exception e) { 
        e.printStackTrace(); 
       } 
      } 

      File f = new File(mImageCaptureUri.getPath());    

      if (f.exists()) f.delete(); 

      break; 

위의 코드 사진 변수에는 사용자의 비트 맵이 있습니다. 당신은 그것을 사용할 수 있습니다. SD 카드의 saved_images 폴더에 이미지가 저장됩니다.
