解决 Attempting to destroy the window while drawing!

当对Dialog进行关闭时，如果有大量的操作，比如动画、绘图什么的，就可能出现这样的错误

 Attempting to destroy the window while drawing! 

比如，我在自定义的Dialog中的dismiss中进行了这样的操作，然后就报错了。其实可以忽略的，但毕竟不爽。

    @Override    public void dismiss() {        Animation anim = AnimationUtils.loadAnimation(context, R.anim.dialog_main_hide_amination);                anim.setAnimationListener(new AnimationListener() {                        @Override            public void onAnimationStart(Animation animation) {            }                        @Override            public void onAnimationRepeat(Animation animation) {            }                        @Override            public void onAnimationEnd(Animation animation) {                                    Dialog.super.dismiss();                            }        });        Animation backAnim = AnimationUtils.loadAnimation(context, R.anim.dialog_root_hide_amin);                view.startAnimation(anim);        backView.startAnimation(backAnim);    }

 

通过Google查到了解决办法。——通过handler来解决

参考网址：http://stackoverflow.com/questions/17923577/dialogfragment-animation-of-layout-and-attempting-to-destroy-the-window-while-d

@Overridepublic void onAnimationEnd(Animation animation) {    Handler handler = new Handler();    handler.postDelayed(new Runnable() {        @Override        public void run() {            dismiss();        }    }, 10);

 

You don‘t need the 10 ms delay. You can simply use the post() method. 

后来，我在下发评论中发现了post可以直接解决，不用10mms的时间。于是就用了post。下面是最终解决问题后的代码：

    @Override    public void dismiss() {        Animation anim = AnimationUtils.loadAnimation(context, R.anim.dialog_main_hide_amination);                anim.setAnimationListener(new AnimationListener() {                        @Override            public void onAnimationStart(Animation animation) {            }                        @Override            public void onAnimationRepeat(Animation animation) {            }                        @Override            public void onAnimationEnd(Animation animation) {                view.post(new Runnable() {                    @Override                    public void run() {                        Dialog.super.dismiss();                    }                });                            }        });        Animation backAnim = AnimationUtils.loadAnimation(context, R.anim.dialog_root_hide_amin);                view.startAnimation(anim);        backView.startAnimation(backAnim);    }
