项目在Fragment切换中出现一个关于View onRestoreInstance()的错误,目前原因没有查到...

出现Crash的地方:

这个IllegalArguementExp导致在部分机型上产生Crash...

// ~ View.java

  @CallSuper
    protected void onRestoreInstanceState(Parcelable state) {
        mPrivateFlags |= PFLAG_SAVE_STATE_CALLED;
        if (state != null && !(state instanceof AbsSavedState)) {
        /// 提示什么 sameid, 但是目前没有发现有重复的Id
        // 可能原因是Fragment恢复状态时,导致View(RecyclerView)出现了这个问题
            throw new IllegalArgumentException("Wrong state class, expecting View State but "
                    + "received " + state.getClass().toString() + " instead. This usually happens "
                    + "when two views of different type have the same id in the same hierarchy. "
                    + "This view's id is " + ViewDebug.resolveId(mContext, getId()) + ". Make sure "
                    + "other views do not use the same id.");
        }
        if (state != null && state instanceof BaseSavedState) {
            mStartActivityRequestWho = ((BaseSavedState) state).mStartActivityRequestWhoSaved;
        }
    }

我想得解决方法就是重写这个RecyclerView的onSaveInstance(), 代码如下

// ~ 自定义RecyclerView中
@Override
protected Parcelable onSaveInstanceState() {
    
    super.onSaveInstanceState();
    // 返回一个空State,相当于没有保存RecyclerView的状态
    return BaseSavedState.EMPTY_STATE;
}

切换Fragment时偶现的Crash解决了,但是不知道会不会引起其他问题?... 因为我没有保存RecyclerView的状态了...哪位熟悉这方面的朋友能不能帮帮我
