Android对话框抛出未连接到窗口管理器

Question

我有以下代码引发异常。其他然后尝试/捕获，无论如何是否可以解决此问题？

@Override
    public void onDestroy() {

            if(dialog != null && dialog.isShowing())
                dialog.dismiss();

        super.onDestroy();
    }

例外

当调用ondestroy（）时，可能会脱离视图，您将获得此例外。您应该将代码移至onpause（）

@Override
public void onPause() {
    super.onPause();
    
    if(dialog != null && dialog.isShowing())
    {
       dialog.dismiss();
    }
}
