问题来自于您的convertView：它是整个列表中使用的同一实例，因此，当异步加载完成时，当listview尝试使用相同的convertView绘制其他项目时，图像会更改（或在这种情况下） ，其子imageView）。
painting position 1, uses placeholder, starts loading image 1 asynchronouslypainting position 2, uses placeholder, starts loading image 2 asynchronouslyimage 1 loading is complete, calling setImageBitmap on imageViewpainting position 3, uses image 1, starts loading image 3 asynchronouslyetc.
但是，您可以做的是在listadapter中保留位图缓存。像这样：
private Bitmap[] bitmapList;private Bitmap bitmapPlaceholder; private void initBitmapListWithPlaceholders(){ // call this whenever the list size changes// you can also use a list or a map or whatever so you // don't need to drop all the previously loaded bitmap whenever // the list contents are modified int count = getListCount(); bitmapList = new Bitmap[count]; for(int i=0;i<count;i++){ bitmapList[i]=bitmapPlaceholder }}private void onBitmapLoaded(int position, Bitmap bmp){// this is your callback when the load async is done bitmapList[position] = bmp;}public View getView(int position, View convertView, ViewGroup parent) { View v = convertView; ImageView imageView; TextView textView; if (v == null) { LayoutInflater vi = (LayoutInflater) getContext().getSystemService( Context.LAYOUT_INFLATER_SERVICE); v = vi.inflate(R.layout.drink_list_row, null); } Drink drink = allItems.get(position); if (drink != null && v != null) { imageView = (ImageView) v.findViewById(R.id.picture); textView = (TextView) v.findViewById(R.id.drinkName); imageView.setVisibility(View.GONE); imageView.setImageBitmap(bitmapList[position]); loadImageBitmap(drink, position); // this should call onBitmapLoaded(int position, Bitmap bmp) when finished to update the bitmapList and replace the placeholder textView.setText(drink.getName()); if (subItems != null && subItems.contains(drink)) { textView.setVisibility(View.VISIBLE); imageView.setVisibility(View.VISIBLE); } else { textView.setVisibility(View.GONE); imageView.setVisibility(View.GONE); } } return v;}
