RecyclerView监听显示的item位置
LinearLayoutManager layoutManager = (LinearLayoutManager) mRecyclerView.getLayoutManager();
int position = layoutManager.findFirstVisibleItemPosition();
LogUtils.d("位置信息"+position);
RecyclerView监听位置监听
LinearLayoutManager layoutManager = (LinearLayoutManager) mRecyclerView.getLayoutManager();
int position = layoutManager.findFirstVisibleItemPosition();
View firstVisiableChildView = layoutManager.findViewByPosition(position);
int itemHeight = firstVisiableChildView.getHeight();
return (position) * itemHeight - firstVisiableChildView.getTop();
注意：
以上方法都放在onScrolled中执行
mRecyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() {
@Override
public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
super.onScrolled(recyclerView, dx, dy);
//调用方法
}
});
