同问，怎么解决

.anchor(getActivity().findViewById(R.id.container))//如果是Activity上增加引导层，不需要设置anchor
注释掉就行了

public HighLight(Context context) {
mContext = context;
mViewRects = new ArrayList<>();
mAnchor = ((Activity) mContext).findViewById(android.R.id.content);
mListenersHandler = new ListenersHandler(this);
registerGlobalLayoutListener();
}

public HighLight anchor(View anchor) {
    mAnchor = anchor;
    registerGlobalLayoutListener();
    return this;
}

在activity使用的时候，构造方法，和anchor都会去注册布局监听，导致会重复注册，所以在acitivty使用引导层，就不设置anchor。同意楼上@lusongcai
