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();
}
}
);
