Android startActivityForResult fecth'yi görüntülemeye çalışıyor Resim Galerisi'nden hata

Question

Galeriden resim almaya çalışıyorum ve bu benim kodum. ne zaman i

mProfilePic.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       Intent i = new Intent(
         Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI); 

       startActivityForResult(i, RESULT_LOAD_IMAGE);//Result_Load_Image =1 
      } 
     }); 



@Override 
    protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
     super.onActivityResult(requestCode, resultCode, data); 

     if (resultCode == RESULT_OK && null != data) { 
      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(); 

      Bitmap bm =BitmapFactory.decodeFile(picturePath); 
      Bitmap resized = Bitmap.createScaledBitmap(bm, 100, 100, true); 
      mProfilePic.setImageBitmap(ProfilePicture.addPicture(resized)); 

     } 


    } 

ve bu benim ImageConvertor kodu

public class ProfilePicture { 
    public static Bitmap getRoundedRectBitmap() { 
     Bitmap result = null; 
     try { 
      result = Bitmap.createBitmap(200, 200, Bitmap.Config.ARGB_8888); 
      Canvas canvas = new Canvas(result); 

      int color = 0xff424242; 
      Paint paint = new Paint(); 
      Rect rect = new Rect(0, 0, 200, 200); 

      paint.setAntiAlias(true); 
      canvas.drawARGB(0, 0, 0, 0); 
      paint.setColor(color); 
      canvas.drawCircle(50, 50, 50, paint); 
      paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.SRC_IN)); 




     } catch (NullPointerException e) { 
     } catch (OutOfMemoryError o) { 
     } 
     return result; 
    } 



     public static Bitmap addPicture(Bitmap bitmap){ 
      Bitmap result = null; 
      try { 
       result = Bitmap.createBitmap(200, 200, Bitmap.Config.ARGB_8888); 
       Canvas canvas = new Canvas(result); 

       int color = 0xff424242; 
       Paint paint = new Paint(); 
       Rect rect = new Rect(0, 0, 200, 200); 

       paint.setAntiAlias(true); 
       canvas.drawARGB(0, 0, 0, 0); 
       paint.setColor(color); 
       canvas.drawCircle(50, 50, 50, paint); 
       paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.SRC_IN)); 

      } catch (NullPointerException e) { 
      } catch (OutOfMemoryError o) { 
      } 
      return result; 
     } 

}

, Ama herhangi bir görüntü seçin, uygulama hemen durur. Birisi bana lütfen kodumun nesi yanlış olduğunu söyler. Teşekkür ederim.

Answer 1

Sorununuz, kodunuzda bir bitmap'in genişliğini aldığınız zamandır.

NullPointerException:

Neden Olduğu: java.lang.NullPointerException: girişimi boş bir nesne referans

Answer 2

ilgili 'int android.graphics.Bitmap.getWidth()' sanal bir yöntem çağırmak deneyin bu kod
