android - 键盘关闭时 Recyclerview 崩溃

Question

我像这样构建一个 recyclerview:

recyclerView = (RecyclerView) view.findViewById(R.id.recyclerview);
recyclerView.setLayoutManager(new LinearLayoutManager(getActivity()));

currentResults = new ArrayList<Stuff>();
stuffAdapter = new StuffAdapter(currentResults, getActivity());
recyclerView.setAdapter(stuffAdapter);

然后当用户搜索事物并返回结果时，它们将以正常方式添加到适配器

currentResults.clear();
currentResults.addAll(searchResponse.results);
restaurantAdapter.notifyDataSetChanged();

这都是非常标准的。结果是通过 appcompat 工具栏中的 searchview 小部件和改造回调获得的。

问题是有一个特定的点，用户可以关闭键盘，UI 调整以适应，然后整个事情崩溃了

java.lang.UnsupportedOperationException: RecyclerView does not support scrolling to an absolute position. at  
android.support.v7.widget.RecyclerView.scrollTo(RecyclerView.java:941) at 
android.view.View.setScrollX(View.java) at  
android.animation.PropertyValuesHolder.nCallIntMethod(Native Method) at 
android.animation.PropertyValuesHolder.access$200(PropertyValuesHolder.java)
at android.animation.PropertyValuesHolder$IntPropertyValuesHolder.setAnimatedValue(PropertyValuesH

没有人调用 scrollto。我不明白为什么要扔这个。任何见解将不胜感激。

阅读另一个 SO 问题:

java.lang.UnsupportedOperationException: RecyclerView does not support scrolling to an absolute position

问题仅出在某些特定设备上，因为那里实现了 ICS。作为建议的解决方法，您可以制作一个 CustomRecyclerView 来扩展 RecyclerView 并覆盖 scrollTo 以捕获错误并阻止应用程序崩溃。

@Override
public void scrollTo(int x, int y) {
    Log.e(TAG, "CustomRecyclerView does not support scrolling to an absolute position.");
    // Either don't call super here or call just for some phones, or try catch it. From default implementation we have removed the Runtime Exception trown 
}
