android 之Spinner下拉菜单实现级联

作者：佚名 Android开发编辑：admin 更新时间：2022-07-23

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：

布局文件代码：

复制代码代码如下:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

</LinearLayout>
