我尝试使用这些示例并阅读我认为与我的项目相关的链接，但所有这些链接都与我的结构不同。希望有人能提供帮助。
我的NewProfile.java类中有3个微调器。在这个课程中，用户可以输入他们的个人资料，还可以选择符合用户兴趣的锻炼类型。保存配置文件输入没有问题。但是我有一个问题是保存用户选择的微调器值。以下是我的代码。
NewProfile.java
public class NewProfile extends Activity {
EditText profileName, profileDOB, profileSex, profileWeight, profileHeight;
Spinner workoutspinner, levelspinner, weightplan1, weightplan2,
weightplan3;
TextView display;
DBController controller = new DBController(this);
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.newdata);
profileName = (EditText) findViewById(R.id.etName);
profileDOB = (EditText) findViewById(R.id.etDOB);
profileSex = (EditText) findViewById(R.id.etSex);
profileWeight = (EditText) findViewById(R.id.etWeight);
profileHeight = (EditText) findViewById(R.id.etHeight);
chooseWorkout();
chooseLevel();
chooseWeight1();
chooseWeight2();
chooseWeight3();
}
public void addNewProfile(View view) {
HashMap<String, String> queryValuesMap = new HashMap<String, String>();
queryValuesMap.put("profileName", profileName.getText().toString());
queryValuesMap.put("profileDOB", profileDOB.getText().toString());
queryValuesMap.put("profileSex", profileSex.getText().toString());
queryValuesMap.put("profileWeight", profileWeight.getText().toString());
queryValuesMap.put("profileHeight", profileHeight.getText().toString());
controller.insertProfile(queryValuesMap);
this.startingpointActivity(view);

我是否需要更改DBController中的任何内容才能保存这些微调器？请帮忙。感谢。
p / s只是告知addNewProfile是一个保存所有信息的按钮。
答案 0 :(得分：0)
好的，我会尽力按要求回答：
首先，这些是设置和获取微调器值的关键部分： 如果您需要在微调器中设置值，可以使用它。
mySpinner.setSelection(arrayAdapter.getPosition("Category 2")); //This assumes that "Category 2" exists in your spinner list.
从你的微调器中获取值。
String Text = mySpinner.getSelectedItem().toString();
以下是关于如何处理这些价值观的精彩讨论。 SharedPreferences example。
这很好地解释了如何保存您的偏好。它也应该给你几乎所有的东西来回答你的初始问题。
之后的关键部分是如何处理这些prefs。此行显示如何根据在已保存的prefs中找到的内容设置字符串，如果找不到任何内容，则会加载“default”。 当用户第一次运行应用程序并且从未设置过prefs时，这很有用。
test_string=shared_preferences.getString("test_key", "Default");
一旦设置了这些首选项，并且您希望它们显示在不同的视图中，只需将所有这些相同的技术添加到另一个视图中。
希望有所帮助。对于它的价值，最后一点是从这里，通过各种搜索。有时，如果一个简单的解决方案不在一个地方，你需要查看一堆不同的东西才能找到答案。
