简单的android studio调查问卷

以下是一个简单的Android Studio调查问卷的实现方法：

1.首先，在布局文件中设计调查问卷的UI界面，可以使用LinearLayout、RelativeLayout等布局方式，添加TextView、EditText、CheckBox、RadioButton等控件，设置好它们的属性。

2.在代码文件中，定义一个按钮的点击事件，当用户点击提交按钮时，获取用户输入的调查问卷信息，并将其保存到数据库中。

3.在代码文件中，使用SQLiteOpenHelper类创建一个数据库，定义一个表来存储调查问卷信息。

4.在代码文件中，定义一个数据模型类，用于封装调查问卷信息。

5.在代码文件中，定义一个数据访问类，用于对数据库进行增删改查操作。

6.在代码文件中，定义一个适配器类，用于将数据模型类中的数据绑定到UI界面上。

以下是一个简单的实现代码：

// 布局文件中的控件
EditText etName, etAge, etGender;
CheckBox cb1, cb2, cb3;
RadioButton rb1, rb2, rb3;
Button btnSubmit;

// 数据库操作类
DatabaseHelper dbHelper;

// 数据模型类
public class Survey {
    public String name;
    public int age;
    public String gender;
    public boolean cb1;
    public boolean cb2;
    public boolean cb3;
    public String rb;
}

// 数据访问类
public class SurveyDAO {
    SQLiteDatabase db;

    public SurveyDAO(Context context) {
        dbHelper = new DatabaseHelper(context);
        db = dbHelper.getWritableDatabase();
    }

    public void addSurvey(Survey survey) {
        ContentValues values = new ContentValues();
        values.put("name", survey.name);
        values.put("age", survey.age);
        values.put("gender", survey.gender);
        values.put("cb1", survey.cb1);
        values.put("cb2", survey.cb2);
        values.put("cb3", survey.cb3);
        values.put("rb", survey.rb);
        db.insert("survey", null, values);
    }

    public List<Survey> getAllSurvey() {
        List<Survey> surveyList = new ArrayList<>();
        Cursor cursor = db.query("survey", null, null, null, null, null, null);
        if (cursor.moveToFirst()) {
            do {
                Survey survey = new Survey();
                survey.name = cursor.getString(cursor.getColumnIndex("name"));
                survey.age = cursor.getInt(cursor.getColumnIndex("age"));
                survey.gender = cursor.getString(cursor.getColumnIndex("gender"));
                survey.cb1 = cursor.getInt(cursor.getColumnIndex("cb1")) == 1;
                survey.cb2 = cursor.getInt(cursor.getColumnIndex("cb2")) == 1;
                survey.cb3 = cursor.getInt(cursor.getColumnIndex("cb3")) == 1;
                survey.rb = cursor.getString(cursor.getColumnIndex("rb"));
                surveyList.add(survey);
            } while (cursor.moveToNext());
        }
        cursor.close();
        return surveyList;
    }
}

// 适配器类
public class SurveyAdapter extends BaseAdapter {
