I have a PreferenceScreen that is defined in XML that serves all the preferences for my application. This PreferenceScreen also has a child PreferenceScreen nested within it. My implementing class is called PreferencesActivity. I know I can open the main Preferences window via startActivity(new Intent(this, PreferencesActivity.class)); but how do I go about opening the child PreferenceScreen via an Intent?

推荐答案

我对这个题目研究了一段时间我的项目盗窃感知（的 http://www.theftaware.com ）（一点点广告... :-)我找到了解决办法：

i researched a while on this topic for my project Theft Aware (http://www.theftaware.com) (a little bit advertisement... :-) and i found the solution:

PreferenceScreen screen = getPreferenceScreen(); // gets the main preference screen     
screen.onItemClick(null, null, INDEX , 0); // click on the item

其中index为要在屏幕上打开该项目的位置

where INDEX is the position of the item you want to open on the screen
