android – 如何在StaggeredGridView中使用setScrollListener

我试图在StaggeredGridView中添加Scroll监听器
在那里,我无法找到一种方法来补充说,我没有看到的任何实现

谢谢

解决方法:

创建一个继承SwipeRefreshLayout并覆盖canChildScrollUp()方法的类来检查StaggeredGridView是否到达顶部,如果到达顶部则返回true,否则返回false.

public class SwipeDownToRefrsh extends SwipeRefreshLayout{

PullToRefreshStaggeredGridView pullToRefreshStaggeredGridView;

public SwipeDownToRefrsh(Context context, AttributeSet attrs) {
    super(context, attrs);
    // TODO Auto-generated constructor stub
}



public void canChildScrollUp (PullToRefreshStaggeredGridView pullToRefreshStaggeredGridView) {
    this.pullToRefreshStaggeredGridView = pullToRefreshStaggeredGridView;
}


@Override
public boolean canChildScrollUp() {
    // TODO Auto-generated method stub
    if (pullToRefreshStaggeredGridView == null) {
        return true;
    } else {
        return !pullToRefreshStaggeredGridView.getRefreshableView().mGetToTop;
    }
}

}

在您的Activity或Fragment中,只需发送StaggeredGridView的瞬间,如下所示：

((SwipeDownToRefrsh)holder.swipeRefreshLayout).canChildScrollUp(holder.staggeredGridView);
