在执行过程中,偶现下面的"this activity mast be extends RootActivity",请问是什么原因引起,又需要如何解决。
public RootActivity getRoot() {
FragmentActivity activity = getActivity();
if (activity instanceof RootActivity) {
return (RootActivity) activity;
} else {
throw new ClassCastException("this activity mast be extends RootActivity");
}
}
