Question

我正在尝试在回收站视图上编写无限滚动的代码。这是给我编译错误的片段：

@Override
            public void onScrolled(RecyclerView recyclerView, int dx, int dy) {

                visibleItemCount = mLayoutManager.getChildCount();
                totalItemCount = mLayoutManager.getItemCount();
                pastVisiblesItems = mLayoutManager.findFirstVisibleItemPosition();

                if ( (visibleItemCount+pastVisiblesItems) >= totalItemCount) {
                    Log.v("...", "Last Item Wow !");
                }

我之前写的声明是：

mLayoutManager = new LinearLayoutManager(this);

mLayoutManager是RecyclerView.LayoutManager类的对象

Answer 1

mLayoutManager is an object of class RecyclerView.LayoutManager错误，您应该android.support.v7.widget.LinearLayoutManager使用mLayoutManager，所以：

mLayoutManager = new LinearLayoutManager(this); 
//above 'LinearLayoutManager' is from
//'android.support.v7.widget.LinearLayoutManager'

mRecyclerView.setLayoutManager(mLayoutManager);

然后mLayoutManager.findFirstVisibleItemPosition();调用onScrolled(...);。

希望这有帮助！

Android：无法解析方法'findFirstVisibleItemPosition（）'？
