首选项默认值未激活

Question

I have a weird problem in my program. I need to click the preference menu before the defaults value are activated. This is not good... How can you make the preference default value activated when the program starts and not when you click on the settings menu? Is there to load the values automatically without clicking the preference menu?

Answer 1

您可以在oncreate（）方法中使用它...

VAT_STRING = preferences.getString("TAXVAT", "5");
