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 ：
代码如下:
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);
