以上代码存在反复添加同一个view1的情况，而

这违反了AdapterView中The specified child already has a parent（已有父控件的子控件再次添加父控件）。

因此，可以按如下更改：

for (int i=;i<tabTitleList.length;i++){
            mTabLayout.addTab(mTabLayout.newTab().setText(tabTitleList[i]));
            View view1=inflater.inflate(R.layout.item_gridview,null);
            mViewList.add(view1);
        }
           

更改后即可正常工作。
