android sharedpreferences

一個很方便的儲存資料方式

如果你的資料只是單純的key value型式

或非常簡單的只是想存一個狀態，

那就用這個吧！！ 非常方便

  public void read(){
        setting = getSharedPreferences(data,0);
        name.setText(settings.getString(nameField, ""));
        phone.setText(settings.getString(phoneField, ""));
        sex.setText(settings.getString(sexField, ""));
    }
    public void save(){
        setting = getSharedPreferences(data,0);
        setting.edit()
            .putString(nameField, name.getText().toString())
            .putString(phoneField, phone.getText().toString())
            .putString(sexField, sex.getText().toString())
            .commit();
    }
