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
@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); }
