갤러리의 내 그림이 표시되지 않는 이유는 무엇입니까?

Question

내 갤러리에서 그림을 선택하고 ImageView에 표시하려고합니다. 사진이 표시되지 않습니다. 왜? 이것은 수명주기의 문제입니까? 또는 setImageBitmap()을 사용하는 방법이 잘못 되었습니까? 어떻게 수정합니까? 도와주세요.

KITKAT의 문제는 해결할 필요가 있습니다.

public static final String KITKAT_VALUE = 1002; 

    Intent intent; 

    if (Build.VERSION.SDK_INT < 19){ 
     intent = new Intent(); 
     intent.setAction(Intent.ACTION_GET_CONTENT); 
     intent.setType("*/*"); 
     startActivityForResult(intent, KITKAT_VALUE); 
    } 
    else 
    { 
     intent = new Intent(Intent.ACTION_OPEN_DOCUMENT); 
     intent.addCategory(Intent.CATEGORY_OPENABLE); 
     intent.setType("*/*"); 
     startActivityForResult(intent, KITKAT_VALUE); 
    } 

@Override 
public void onActivityResult(int requestCode, int resultCode, Intent data) { 

    if (resultCode == Activity.RESULT_OK && data!=null) { 
      Uri selectedImage = data.getData(); 
      String[] filePathColumn = { MediaStore.Images.Media.DATA }; 

      Cursor cursor = getContentResolver().query(selectedImage, 
       filePathColumn, null, null, null); 
      cursor.moveToFirst(); 

      int columnIndex = cursor.getColumnIndex(filePathColumn[0]); 
      String picturePath = cursor.getString(columnIndex); 
      cursor.close(); 
      imageButton.setImageBitmap(BitmapFactory.decodeFile(picturePath)); 

    } 
}
