-
在我的应用程序中，我有动态微调器。
-
一个方法中总共有 2 个微调器，两者都是依赖的（SPinner1 ，微调器2）。
-
我可以多次调用该方法。
-
微调器数据从本地数据库加载。
问题：
我称该方法为两次 所以活动总共显示了 4 个微调器。
1a.spinner1
1b.SPinner2
2a.Spinner1
2b.Spinner2
根据我选择的第三个微调器，第四个微调器数据正在完美加载。
但基于第一个微调器选定项数据 未显示在第二个微调器中，因为上次迭代数据（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。 在所有微调器中显示数据。

我还没有测试过这个。希望对您有所帮助。
在向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);
