问题：
Android Spinner选择的项目在下一个活动开始时获得更改
纪畅
在我的应用程序中，我在一个活动中使用了不止一个纺纱器，一切都很好，但当我开始另一个活动时，根据我当前活动中的纺纱器的选定项目，所有选定的纺纱器项目都自行获得对其“0”索引值的更改。当我从下一个活动返回到带有旋转器的活动时（即，当活动恢复时），它所选的值被设置为“0”索引。我怎样才能阻止旋转者在开始另一个活动时改变其选定项目的行为。

如何使用SaveInstanceState
@Override
public void onSaveInstanceState(Bundle outState) {//store your instance here
outState.putString("message", "This is my message to be reloaded");
super.onSaveInstanceState(outState);
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (savedInstanceState != null) {//load your instance here
int position= savedInstanceState.getInt("InterestSpinner",0);
spinner.setSelection(interestSpiner);
}
}
或
@Override
protected void onRestoreInstanceState(Bundle savedInstanceState) {
super.onRestoreInstanceState(savedInstanceState);
int position= savedInstanceState.getInt("InterestSpinner",0);
spinner.setSelection(interestSpiner);
}

问题内容： 我正在使用实质性的UI Select组件，并且试图在内部构建过滤器以仅显示与用户输入的内容匹配的项目。 我为正在开发的内容构建了一个最小的示例。 现在我的问题是，默认情况下，选择组件允许用户按下任何字母，并且如果存在第一个字母与用户输入匹配的选项，它将选择该选项。 所以，如果我有3个选项（，和）和用户类型选择部件将选择选项，我的文本字段不会改变的价值。但是，如果用户键入，则文本字段将更
