SwipeRefreshLayout下拉刷新跟listview下拉滑动冲突解决

当SwipeRefreshLayout内嵌listview的时候，滑动listview的时会启动swipeRefreshLayout的下拉刷新。我使用的解决办 法是设置listview的滑动监听，重写滑动监听器，通过判断listview的第一可视item的index来判断是否需要刷新，如果不 需要就把swipeRefreshLayout设置成不可滑动，否则设置成可滑动。 我的listview放在了fragment里面，所以我用了最笨的方法，在fragment的构造方法里把activity的swipeRefreshLayout 对象传递给了fragment： MyManageFragment manageFragment = new MyManageFragment(swipeRefreshLayout); transation.add(R.id.activity_mydevice_container, manageFragment); transation.commit(); 然后在fragment的onCreateView里面设置其listview的滑动监听： listview.setOnScrollListener(new SwpipeListViewOnScrollListener(swipeRefreshLayout)); 然后重写滑动监听器，通过判断listview的第一个可视的item的位置来决定是下拉刷新还是下滑，判断到是下滑的时候， 通过设置传入的swipeRefreshLayout对象使其不可用： swipeRefreshLayout.setEnabled(false); 重写监听器： /** * 由于Listview与下拉刷新的Scroll事件冲突, 使用这个ScrollListener可以避免Listview滑动异常 */ public class SwpipeListViewOnScrollListener implements AbsListView.OnScrollListener { private SwipeRefreshLayout mSwipeView; private AbsListView.OnScrollListener mOnScrollListener; public SwpipeListViewOnScrollListener(SwipeRefreshLayout swipeView) { mSwipeView = swipeView; } public SwpipeListViewOnScrollListener(SwipeRefreshLayout swipeView, AbsListView.OnScrollListener onScrollListener) { mSwipeView = swipeView; mOnScrollListener = onScrollListener; } @Override public void onScrollStateChanged(AbsListView absListView, int i) { } @Override public void onScroll(AbsListView absListView, int firstVisibleItem, int visibleItemCount, int totalItemCount) { View firstView = absListView.getChildAt(firstVisibleItem); // 当firstVisibleItem是第0位。如果firstView==null说明列表为空，需要刷新;或者top==0说明已经到达列表顶部, 也需要刷新 if (firstVisibleItem == 0 && (firstView == null || firstView.getTop() == 0)) { mSwipeView.setEnabled(true);//可刷新 } else { mSwipeView.setEnabled(false);//不能刷新，此时为滑动 } if (null != mOnScrollListener) { mOnScrollListener.onScroll(absListView, firstVisibleItem, visibleItemCount, totalItemCount); } } } PS: 一开始想在activity里获取到frgment里面的listview对象，在activity里设置listview的滑动监听器,但是没有成功,对 于fragment和activity的交互，理解还不是很够。 MyManageFragment manageFragment = new MyManageFragment(); transation.add(R.id.activity_mydevice_container, manageFragment，"mymanage_fragment"); transation.commit(); getSupportFragmentManager().executePendingTransactions(); //1-------------- MymanageFragment myManageFragment = (MymanageFragment) getSupportFragmentManager().findFragmentByTag("mymanage_fragment"); if (myManageFragment != null) { ListView listView = (ListView) myManageFragment.getView().findViewById(R.id.listview_mymanage); listView.setOnScrollListener(new SwpipeListViewOnScrollListener(swipeRefreshLayout)); } else { toast("myManageFragment is null"); }其中 myManageFragment.getView()返回的是null，有待进一步解决
