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

@Override
public 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);
    }
