推荐答案

我张贴code删除从列表视图这是正常工作在我的code项目。

I am posting code for deleting item from listview which is working correctly in my code.

您忘了叫notifysetchanged完蛋了。

You forgot to call notifysetchanged thats it.

@Override public View getView(int position, View convertView, ViewGroup parent) { View row = null; LayoutInflater inflater = getLayoutInflater(); row = inflater.inflate(R.layout.one_result_details_row, parent, false); // inflate other items here : Button deleteButton = (Button) row.findViewById(R.id.Details_Button01); deleteButton.setTag(position); deleteButton.setOnClickListener( new Button.OnClickListener() { @Override public void onClick(View v) { Integer index = (Integer) view.getTag(); items.remove(index.intValue()); notifyDataSetChanged(); } } );
