问题描述

如何将活动保存在listView首选项中，以便当用户在首选项中选择一项活动时，以便当用户下次启动应用程序时，它们将显示为第一个屏幕?

How can activities be saved in listView preferences so that when a User selects an activity in preferences so that when user starts the app next time they will appear as a first screen?

推荐答案

当用户选择要保存其首选项的Activity时，您可以将该Activity的名称保存到sharedPreferences中. 然后在您的MainActivity类中，当应用再次运行时，检查保存的活动并启动.

When user choose an Activity to save on it's preferences,You can save name of that Activity to sharedPreferences. Then in your MainActivity class when app runs again, check for saved activity and start that.

请参见此SO问题

要保存为首选项:

PreferenceManager.getDefaultSharedPreferences(context).edit().putString("MYACTIVITY", "myStringToSave").commit();

要获取存储的首选项:

PreferenceManager.getDefaultSharedPreferences(context).getString("MYACTIVITY", "defaultStringIfNothingFound"); 

其中myStringToSave可以是所选活动的名称

where myStringToSave could be name of chosen activity
