listview的长按事件

如果适配器发生变化，需要当前的listview也通知到

1、list.remove(position);

adapter=new ArrayAdapter<String>(MainActivity.this, R.layout.arrayadapter, list);
lv.setAdapter(adapter);

return true;

2、 lv.setOnItemLongClickListener(new OnItemLongClickListener() {


@Override
public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {
// TODO Auto-generated method stub
list.remove(position);
adapter.notifyDataSetChanged();
return true;
}
});
