在下面的代码中，用户输入一组属性，然后需要存储它们，然后使用 CaluculateCalories() 计算它返回我也想存储在 sharedpreferences 中的卡路里数 (Calnum)。怎么可能做到这一点？这是一段代码，我只需要在 Savepreferences 中添加一些行，我只是不知道如何。
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.createprofile);
SharedPreferences customSharedPreference = getSharedPreferences(
"myCustomSharedPrefs", Activity.MODE_PRIVATE);
name = (EditText) findViewById(R.id.namefield);
name.setText(customSharedPreference.getString("namepref", ""));
age = (EditText) findViewById(R.id.agefield);
// int Age = Integer.parseInt(age.getText().toString());
age.setText(customSharedPreference.getString("agepref", ""));
genderradiogroup = (RadioGroup) findViewById(R.id.radioGroup2);
rb_male = (RadioButton) findViewById(R.id.maleradiobutton);
rb_female = (RadioButton) findViewById(R.id.femaleradiobutton);
genderradiogroup.check(customSharedPreference.getInt("genderprefs",
rb_male.getId()));
weight = (EditText) findViewById(R.id.weightfield);
// int Weight = Integer.parseInt(weight.getText().toString());
weight.setText(customSharedPreference.getString("weightpref", ""));
