推荐答案

GoogleIO 应用有一个 ActivityHelper 类.它有一个名为 initialize() 的静态方法，它处理每个 Activity 发生的很多事情.然后您只需要记住 onCreate() 方法中的 1 行代码，它可以处理设置该值以及每个活动所需的其他几个值.

The GoogleIO app has a ActivityHelper class. It has a static method called initialize() which handles a lot things that happen for every Activity. Then it is just 1 line of code in the onCreate() method that you need to remember, that could handle setting that value and several others that are necessary for each activity.

没有导入或类似的东西.创建一个名为 ActivityHelper 的类

No importing or anything like that. Create a class called ActivityHelper

public class ActivityHelper {
    public static void initialize(Activity activity) {
        //Do all sorts of common task for your activities here including:

        activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
    }
}

然后在你所有的活动中调用 onCreate() 方法 ActivityHelper.initialize()如果您还计划开发表格，您可能需要考虑使用:

Then in all of your activies onCreate() method call ActivityHelper.initialize() If you are planning on developing for tables as well you may want to consider using:

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_NOSENSOR);

抱歉...您需要传递活动.看上面的代码

Sorry... you need to pass the the Activity. see the code above
