android - 外部获取RecyclerView中viewholder持有的控件

Question

使用

CrimeHolder holder1 = (CrimeHolder) mCrimeRecyclerView.findViewHolderForAdapterPosition(1);

然后使用holder1.getxxxx();

但是我在外部调用时提示
·······getTitleTextView()' on a null object reference，调试发现holder1为null，求解决方案

调用时机：Fragment的onResume()方法中。

Not sure, it’s best to add more code
If it involves related logic after the view layer is created, it’s best to execute it in view.post.

view.post(new Runnable(){
//这里在view加载完毕之后将得到执行

})
