我定义了gridview和gridviewadapter来选择图像。选择2个或更多图像时,一切运行良好。但是,当我选择1时,位置= 1被positon = 0中的图像覆盖,这仅在第一次选择1图像时发生。流程是适配器中的getView():
"launch" : [
{ _id: '56cea954d82cd11004ee67b5',
.... other fields
},
{ _id: '56ceaa00d82cd11004ee67bc',
.... other fields
},
]
错误显示: enter image description here
正确显示: enter image description here
xml文件:
@Override
public View getView(final int position, View convertView, final ViewGroup parent) {
L.d("mytest position ="+position+ "converView ="+convertView);
Holder holder;
if (convertView == null) {
holder = new Holder();
convertView = mInflater.inflate(R.layout.grid_view_item, null);
holder.mSelectImage = (NGImageView) convertView.findViewById(R.id.iv_icon);
convertView.setTag(holder);
} else {
holder = (Holder) convertView.getTag();
}
if (getData().size() > 0 && position != getData().size()) {
holder.mSelectImage.setVisibility(View.VISIBLE);
ImageItem imageItem = getData().get(position);
if (imageItem != null) {
if (imageItem.getImageUri().toString().startsWith("http")) {
loadNGImageView.LoadOptionsView(imageItem.getImageUri().toString(),holder.mSelectImage);
} else {
String imgUrl = BitmapUtil.IMAGE_URI_SUFFIX_SDCARD + imageItem.getImageUri().getPath();
L.d("mytest LoadOptionsView");
loadNGImageView.LoadOptionsView(imgUrl,holder.mSelectImage);
}
}
} else {
if (position == TopicPostFragment.DEFAULT_PHOTO_COUNT) {
holder.mSelectImage.setVisibility(View.GONE);
} else {
holder.mSelectImage.setVisibility(View.VISIBLE);
L.d("mytest setImageResource");
holder.mSelectImage.setImageResource(R.drawable.guild_icon_img);
}
}
return convertView;
}

答案 0 :(得分:0)
setImageResource不能与setImageURL同时使用,有时setImageURL可能会覆盖setImageResource并使显示错误。 如果你同时使用它们,你应该先设置ImageURL(null),然后使用setImageResource。
