适配器

public class ListAdapter extends BaseAdapter {
private LayoutInflater inflater;
Context context;
private ArrayList<String> responseList;
private LinearLayout parent_choice_list_container;
private TextView item_name;
private ImageView iv_choice_list_item_selected;
public ListAdapter (Context context, ArrayList<String> responseList) {
this.context = context;
this.responseList = responseList;
inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
public void setSelectedIndex(int ind) {
selectedIndex = ind;
notifyDataSetChanged();
}
@Override
public int getCount() {
return responseList.size();
}
@Override

}
@Override

片段部分(项目单击侦听器(

@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
response.get(position).setSelected(true);
ListAdapter.notifyDataSetChanged(); 
}

Answer 1

听起来您正在使用CheckBox。

您是否尝试过根据项目是否isChecked(而不是isSelected(有条件地更新View的可见性？

Answer 2

您应该为每个图像设置标签以跟踪其状态(0 = 未选择/不可见，1 = 选定/可见(，例如：

if (responseList.get(position).isSelected()) {
iv_choice_list_item_selected.setTag(1);
}

你可以添加这个：

if (iv_choice_list_item_selected.getTag() == 1) {
iv_choice_list_item_selected.setVisibility(View.VISIBLE);
} else {
iv_choice_list_item_selected.setVisibility(View.GONE);
}
