以编程方式触发SwipeRefreshLayout

Question

有没有办法以SwipeRefreshLayout编程方式触发？应该启动动画,并且应该调用界面中的onRefresh方法OnRefreshListener.

Answer 1

如果您使用的是5.0中的新swipeRefreshLayout

如上图所示,您只需添加以下行以编程方式触发滑动刷新布局

 mSwipeRefreshLayout.post(new Runnable() {
        @Override
        public void run() {
            mSwipeRefreshLayout.setRefreshing(true);
        }
    });

如果你只是打电话

 mSwipeRefreshLayout.setRefreshing(true);

它不会触发圆形动画,所以通过添加上面的线你只是在UI线程中延迟,以便它显示ui线程内的圆形动画.

通过调用mSwipeRefreshLayout.setRefreshing(true)的OnRefreshListener将不会得到执行

为了停止循环加载动画调用 mSwipeRefreshLayout.setRefreshing(false)

Answer 2

为了触发SwipeRefreshLayout,我尝试了这个解决方案:

SwipeRefreshLayout.OnRefreshListener swipeRefreshListner = new SwipeRefreshLayout.OnRefreshListener() {
        @Override
        public void onRefresh() {
            Log.i(TAG, "onRefresh called from SwipeRefreshLayout");
            // This method performs the actual data-refresh operation.
            // The method calls setRefreshing(false) when it's finished.
            loadData();
        }
    };

现在关键部分:

swipeLayout.post(new Runnable() {
@Override public void run() {
     swipeLayout.setRefreshing(true);
     // directly call onRefresh() method 
     swipeRefreshListner.onRefresh();
   }
});
