在传递一个接口的时候会报空指针错误 about rxbus HOT 4 CLOSED

在 2018年6月1日，下午4:44，qianshengta ***@***.***> 写道： public interface OnFragmentInteractionListener extends Serializable { void onFragmentInteraction(Bundle var1); } 这是我的一个接口，我的MainFragment实现这个接口，然后传递出去 // 发送带 tag 的 OnFragmentInteractionListener 类型事件 RxBus.getDefault().postSticky(this, "MainFragment"); 我的另外一个接口去接收这个数据 // 注册带 tag 的 OnFragmentInteractionListener 类型事件 RxBus.getDefault().subscribeSticky(this, "MainFragment", new RxBus .Callback<OnFragmentInteractionListener>() { @OverRide public void onEvent(OnFragmentInteractionListener listener) { } }); 然后在接收的那个页面就报空指针了，以下是错误的log java.lang.NullPointerException: Attempt to invoke virtual method 'int java.lang.Object.hashCode()' on a null object reference at java.util.concurrent.ConcurrentHashMap.get(ConcurrentHashMap.java:772) at com.blankj.rxbus.CacheUtils.findStickyEvent(Unknown Source) at com.blankj.rxbus.RxBus.subscribe(Unknown Source) at com.blankj.rxbus.RxBus.subscribeSticky(Unknown Source) at com.fubang.renewableresourcesclient.ui.home.BookingResultFragment.initParam(BookingResultFragment.java:61) at com.qian.qianlibrary.base.fragment.BaseFragment.onResume(BaseFragment.java:104) at android.support.v4.app.Fragment.performResume(Fragment.java:2390) at android.support.v4.app.FragmentManagerImpl.moveToState(FragmentManager.java:1474) at android.support.v4.app.FragmentManagerImpl.moveFragmentToExpectedState(FragmentManager.java:1759) at android.support.v4.app.FragmentManagerImpl.moveToState(FragmentManager.java:1827) at android.support.v4.app.BackStackRecord.executeOps(BackStackRecord.java:797) at android.support.v4.app.FragmentManagerImpl.executeOps(FragmentManager.java:2596) at android.support.v4.app.FragmentManagerImpl.executeOpsTogether(FragmentManager.java:2383) at android.support.v4.app.FragmentManagerImpl.removeRedundantOperationsAndExecute(FragmentManager.java:2338) at android.support.v4.app.FragmentManagerImpl.execPendingActions(FragmentManager.java:2245) at android.support.v4.app.FragmentManagerImpl$1.run(FragmentManager.java:703) at android.os.Handler.handleCallback(Handler.java:743) at android.os.Handler.dispatchMessage(Handler.java:95) at android.os.Looper.loop(Looper.java:150) at android.app.ActivityThread.main(ActivityThread.java:5621) at java.lang.reflect.Method.invoke(Native Method) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:794) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:684) — You are receiving this because you are subscribed to this thread.
