解決 Attempting to destroy the window while drawing!

當對Dialog進行關閉時，若是有大量的操做，好比動畫、繪圖什麼的，就可能出現這樣的錯誤

 Attempting to destroy the window while drawing! 

好比，我在自定義的Dialog中的dismiss中進行了這樣的操做，而後就報錯了。其實能夠忽略的，但畢竟不爽。

    @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);
    }

 

經過Google查到了解決辦法。——經過handler來解決

參考網址：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. 

後來，我在下發評論中發現了post能夠直接解決，不用10mms的時間。因而就用了post。下面是最終解決問題後的代碼：

    @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);
    }
