我想使用以下代码设置图像视图的背景：

String color = (cursor.getString(cursor.getColumnIndex(NotesDbAdapter.KEY_COLOR)));
            ImageView background=(ImageView)view.findViewById(R.id.album_image);
            DecodeTask task = (DecodeTask)background.getTag(R.id.album_image);
            background.setScaleType(ImageView.ScaleType.CENTER_CROP);

            String imageCheck = (cursor.getString(cursor.getColumnIndex(NotesDbAdapter.KEY_IMAGE)));
            if (imageCheck != 0){
                 background.setImageBitmap(BitmapFactory.decodeFile(imageCheck));
            }
            else if (color != null && !color.isEmpty()){
                if (color.equals("1")){
                    task = new DecodeTask(background);
                    background.setImageResource(R.drawable.bluebg);
                }
                else if (color.equals("2")){
                    task = new DecodeTask(background);
                    background.setImageResource(R.drawable.greenbg);
                }
                else if (color.equals("3")){
                    task = new DecodeTask(background);
                    background.setImageResource(R.drawable.yellowbg);
                }
                else if (color.equals("4")){
                    task = new DecodeTask(background);
                    background.setImageResource(R.drawable.redbg);
                }
                else if (color.equals("5")){
                    task = new DecodeTask(background);
                    background.setImageResource(R.drawable.purplebg);
                }
            }

但是，当 imageCheck 等于 0 时，它不会读取进一步的代码并为图像设置默认背景。我应该怎么办？

尝试改变

if(imageCheck != 0)

至

if(!imageCheck.equals("0"))

因为你正在比较一个字符串
