조각을 사용하여 갤러리에서 이미지를 가져올 수 없습니다.

Question

갤러리에서 이미지를 가져 와서 imageView의 초기 이미지를 바꾸고 싶습니다. 갤러리에서 이미지를 선택하더라도 변경되지 않습니다.

중단 점을 사용하여 어딘가까지 정상적으로 작동하는지 조사했습니다. onActivityResult의 try-catch의 다음 코드 부분이 원인 인 것 같습니다.

InputStream in = getActivity().getContentResolver().openInputStream(data.getData()); 

이미지의 원인은 무엇입니까?

public class Fragment1 extends Fragment { 

    private static final int REQUEST_GALLERY = 0; 
    private int viewWidth, viewHeight; 
    private ImageView imageView; 

    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceBundle){ 

     final View view = inflater.inflate(R.layout.fragment_person_create, container, false); 
     Bitmap bmp = BitmapFactory.decodeResource(getResources(), R.drawable.image); 
     imageView = (ImageView) view.findViewById(R.id.image_id); 
     imageView.setImageBitmap(bmp); 
     imageView.setOnClickListener(new OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       // To Gallery 
       Intent intent = new Intent(); 
       intent.setType("image/*"); 
       intent.setAction(Intent.ACTION_GET_CONTENT); 
       startActivityForResult(intent, REQUEST_GALLERY); 
      } 
     }); 
     Button btn = (Button)view.findViewById(R.id.bt_saveperson); 
     btn.setOnClickListener(new OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       EditText name = (EditText)view.findViewById(R.id.et_name); 
       /* save data */ 
      } 
     } 
     return view; 
    } 

    @Override 
    public void onActivityResult(int requestCode, int resultCode, Intent data) { 
     if(requestCode == REQUEST_GALLERY && resultCode == Activity.RESULT_OK) { 
      try { 
       InputStream in = getActivity().getContentResolver().openInputStream(data.getData()); 
       Bitmap bitmap = BitmapFactory.decodeStream(in); 
       in.close(); 
       imageView.setImageBitmap(bitmap); 
      } catch (Exception e) { 
      } 
     } 
    } 
}

를 사용하여 사용자 정의 함수를 가져 오기 이미지 bitamp의 절대 경로 얻을 :)
