        为避免内存泄漏，正确写法应该是写个内部静态类+弱引用：

private static class MyHandler extends Handler {        private WeakReference
   
     activityWeakReference;        public MyHandler(LoginActivity activity) {            activityWeakReference = new WeakReference<>(activity);        }        @Override        public void handleMessage(Message msg) {            super.handleMessage(msg);            LoginActivity activity = activityWeakReference.get();            if (activity != null) {                           }        }    }
