Android取消作物不會返回活動結果

Question

我可以從圖庫中選取圖像，裁剪並將其作爲bundle獲取。我以這種方式檢索它：

if (resultCode == Activity.RESULT_OK) { 
     if (requestCode == SELECT_IMAGE || requestCode == SELECT_LANDSCAPE_IMAGE) { 
      Bundle extras = data.getExtras(); 
      Bitmap photo = extras.getParcelable("data"); 
       ......................... 
     } 
} 

一切工作正常。但是當我取消裁剪時，不會收到任何包。我想在取消裁剪時收到實際的位圖。我怎樣才能做到這一點？

Answer 1

我已經找到了解決辦法：

if (requestCode == CROP_FROM_CAMERA && resultcode == RESULT_CANCELED { 
    // crop was cancelled 
}

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

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

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

      // some devices (OS versions return an URI of com.android 
      // instead of com.google.android 
      if (selectedImage.toString().startsWith(
        "content://com.android.gallery3d.provider")) { 
       // use the com.google provider, not the com.android 
       // provider. 
       selectedImage = Uri.parse(selectedImage.toString().replace(
         "com.android.gallery3d",

      GraphicsUtil graphicUtil = new GraphicsUtil(); 
      // picView.setImageBitmap(graphicUtil.getRoundedShape(thePic,(float)1.5,92)); 
      mProfilePic.setImageBitmap(graphicUtil.getCircleBitmap(
        thePic, 16)); 
     Toast.makeText(RegistrationActivity.this, mPicturePath + "", Toast.LENGTH_LONG).show(); 

    } 
    else if (requestCode == AppConstant.CROP_IMAGE && resultCode == RESULT_CANCELED) { 
     Toast.makeText(RegistrationActivity.this, mPicturePath + "", Toast.LENGTH_LONG).show(); 

    }
