Android 如何将微调器保存为共享首选项？

我已经能够将整数和字符串保存为共享首选项，但已经搜索，似乎无法将微调器选定值保存为共享首选项

        spinner = (Spinner)findViewById(R.id.spnCalorieRange); 
        adapter = ArrayAdapter.createFromResource(this, R.array.Calorie_Range, android.R.layout.simple_spinner_dropdown_item);
        adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        spinner.setAdapter(adapter);

        spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {

            @Override
            public void onItemSelected(AdapterView<?> parent, View view,
                    int position, long id) {
                long item = parent.getItemIdAtPosition(position);
                String pos =spinner.getSelectedItem().toString();
                //sharedPreferences.edit().putInt("PREF_SPINNER", position).commit();
                if (item == 0){
                    deficitPercentage = .05;
                }
                else if (item ==1)
                {
                    deficitPercentage = .1;
                }
                else if (item ==2)
                {
                    deficitPercentage = .15;    
                }
                else if (item ==3)
                {
                    deficitPercentage = .2;
                }
                else if (item ==4)
                {
                    deficitPercentage = .25;
                }
                else
                {
                    deficitPercentage = .3;
                }
                editor.putString("pos", pos);
                editor.commit();
            }

            @Override
            public void onNothingSelected(AdapterView<?> parent) {
                // TODO Auto-generated method stub

            }

        });

下面是保存共享首选项的按钮： 顺便说一句，字符串保存得很好

  Button btnBack = (Button)findViewById(R.id.btnBack);
    btnBack.setOnClickListener(new View.OnClickListener() {
            @Override
        public void onClick(View v) {

                     String strAvgCalIntake =       Double.toString(dailyCalorieIntake);
                    String strGoal = loadSavedPreference("strGoal");
                spnCalorieRange = (Spinner) findViewById(R.id.spnCalorieRange);

                    strAvgCalIntake = etAverageCalorieIntake.getText().toString();
                    savePreference("strAvgCalIntake",strAvgCalIntake);

                strGoal = etLoseWeight.getText().toString();
                savePreference("strGoal",strGoal);

                    SharedPreferences spref = getSharedPreferences("pref", Activity.MODE_PRIVATE);
                    SharedPreferences.Editor editor = spref.edit();
                editor.putString("deficitPercentage_key", Double.toString(deficitPercentage)); //
                    editor.commit();

如果您已经验证了

deficitPercentage

值，（我希望您已经验证了）

验证deficitPercentage是什么意思？如果deficitPercentage未被任何其他模块修改，则可以，但您应将.05、0.2替换为a常量，这样更好，并将提高应用程序的质量…好的，谢谢。因此，我在onClick按钮中添加了该块，我正在保存其他变量，但不幸的是，它似乎不起作用。以及您如何从SharedReferences读取该值。发布该部分代码。该代码现在已发布，感谢您的帮助，非常感谢：）

  Button btnBack = (Button)findViewById(R.id.btnBack);
    btnBack.setOnClickListener(new View.OnClickListener() {
            @Override
        public void onClick(View v) {

                     String strAvgCalIntake =       Double.toString(dailyCalorieIntake);
                    String strGoal = loadSavedPreference("strGoal");
                spnCalorieRange = (Spinner) findViewById(R.id.spnCalorieRange);

                    strAvgCalIntake = etAverageCalorieIntake.getText().toString();
                    savePreference("strAvgCalIntake",strAvgCalIntake);

                strGoal = etLoseWeight.getText().toString();
                savePreference("strGoal",strGoal);

                    SharedPreferences spref = getSharedPreferences("pref", Activity.MODE_PRIVATE);
                    SharedPreferences.Editor editor = spref.edit();
                editor.putString("deficitPercentage_key", Double.toString(deficitPercentage)); //
                    editor.commit();

SharedPreferences spref = getSharedPreferences("your_prefs_name", Activity.MODE_PRIVATE);
SharedPreferences.Editor editor = spref.edit();
editor.putString("deficitPercentage_key", Double.toString(deficitPercentage)); //
editor.commit();
