滚动Android Recyclerview更新日历

Question

我有一个上面的日历recyclerview。如果我通过当天的事件滚动回收站视图，如何更新日历中的当前日期。

Answer 1

是，RecyclerVew提供addOnScrollListener方法

私人OnScrollLoadMore mOnScrollLoadMore; // initalize在活动类 recycler_view.addOnScrollListener（mOnScrollLoadMore）; //添加onScrollListener到recyclerview

公共类OnScrollLoadMore扩展RecyclerView。 OnScrollListener {

private IOnScrollListener mOnScrollListener; 
private LinearLayoutManager mLayoutManager; 
private Activity mContext; 
private boolean mLoading = true; 

public interface IOnScrollListener { 
    void onScrollComplete(); 
} 

public OnScrollLoadMore(Activity activity, LinearLayoutManager layoutManager) { 
    this.mContext = activity; 
    this.mLayoutManager = layoutManager; 
} 

public void setOnScrollListener(IOnScrollListener onScrollListener) { 
    this.mOnScrollListener = onScrollListener; 
} 

public void setLoading(boolean loading) { 
    this.mLoading = loading; 
} 

@Override 
public void onScrollStateChanged(RecyclerView recyclerView, int newState) { 
    super.onScrollStateChanged(recyclerView, newState); 
    Utils.hide_keyboard(mContext); 
} 

@Override 
public void onScrolled(RecyclerView recyclerView, int dx, int dy) { 
    super.onScrolled(recyclerView, dx, dy); 
       setLoading(false); 
       mOnScrollListener.onScrollComplete(); 
} 

}

//在活动你想要的）的事件触发 覆盖 公共无效onScrollComplete（{// 做你的工作 }

执行你的更新当前日期
