android 之Spinner下拉菜单实现级联
效果图如下:
默认第一次加载
选择原始队列:
级联效果图:
关键代码给下拉列表选中事件监听绑定id :
int pos = firsthand_dlbh_pinner.getselecteditemposition();
firsthand_pdbh_adapter = new arrayadapter<string>(context,
android.r.layout.simple_spinner_item, queu_info[pos]);
firsthand_pdbh_spinner.setadapter(firsthand_pdbh_adapter);
