我正在尝试使用AndroID兼容性软件包v4,使用基于片段的设计替换我的应用程序中的tabactivity.

我遇到的问题是我的tabactivity中的一个选项卡是PreferencesActivity,由于显而易见的原因,我无法从FragmentActivity启动.

所以,既然,PreferenceFragment没有包含在AndroID兼容包中,我也无法从我的片段活动中启动PreferenceActivity,我该怎么办？

对任何建议开放.

编辑：尝试从我的片段活动打开PreferenceActivity时得到的异常在这里：

FATAL EXCEPTION: mainjava.lang.IllegalStateException: DID you forget to call 'public voID setup(LocalActivityManager activityGroup)'?    at androID.Widget.TabHost$IntentContentStrategy.getContentVIEw(TabHost.java:652)    at androID.Widget.TabHost.setCurrentTab(TabHost.java:326)    at androID.Widget.TabHost.onTabSelectionChanged(TabHost.java:132)    at androID.Widget.TabWidget$TabClickListener.onClick(TabWidget.java:456)    at androID.vIEw.VIEw.performClick(VIEw.java:2485)    at androID.vIEw.VIEw$PerformClick.run(VIEw.java:9080)    at androID.os.Handler.handleCallback(Handler.java:587)    at androID.os.Handler.dispatchMessage(Handler.java:92)    at androID.os.Looper.loop(Looper.java:130)    at androID.app.ActivityThread.main(ActivityThread.java:3683)    at java.lang.reflect.Method.invokeNative(Native Method)    at java.lang.reflect.Method.invoke(Method.java:507)    at com.androID.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:839)    at com.androID.internal.os.ZygoteInit.main(ZygoteInit.java:597)    at dalvik.system.NativeStart.main(Native Method)

我的FragmentActivity代码如下(大部分内容来自’tabs’的兼容包v4示例)：

EDIT2：为了清楚起见,还添加了示例代码：

解决方法 请参阅v7支持库的 latest revision,该库引入了 PreferenceFragmentCompat. 总结
