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 :

复制代码 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);

完整代码:
