在我的应用程序中，我有动态旋转器。
方法中共有2个旋转器，两者都是相关的（SPinner1，Spinner2）。
我可以多次调用该方法。
从本地数据库加载微调器数据。
问题：
我两次调用该方法所以活动显示完全4个旋转器。
1a.spinner1
1b.SPinner2
2a.Spinner1
2b.Spinner2
根据我选择的第三个Spinner，第四个Spinner数据加载完美。
但基于第一个微调器所选项目数据未显示在第二个微调器中，因为最后一个迭代数据（第三个和第四个微调器）仅存储在字符串数组中。
请帮我解决这个问题。显示所有微调器中的数据。
我创建动态SPinners的方法

我没有测试过这个。希望对你有所帮助。

mContainerView.addView(rowView123);添加视图之前首先删除以前的子视图。
//snippet.
//remove all views
mContainerView.removeAllViews();
//add new views
mContainerView.addView(rowView123);
