推荐答案

，使全通RequestFilter。

Instead of using a tag for cancelAll, make an all-pass RequestFilter.

mRequestQueue.cancelAll(new RequestQueue.RequestFilter() {
    @Override
        public boolean apply(Request<?> request) {
            return true;
        }
    });

编辑：这将取消所有活动/片段的所有请求，并且不与Activity生命周期毫不逊色工作。管理最好的方法是将字符串标记独特添加到您的片段。

This cancels all Requests from all activities/fragments, and doesn't work favorably with the Activity Lifecycle. The best way to manage this is to add a String tag unique to your fragment.
