百度解释：

webViwe的放大缩小按钮在设置显示状态下，显示和隐藏需要一定的时间过程

在界面消失之前，当清楚webView所有view

处理方式：

@Override
        protected void onDestroy() {
            int sysVersion = Build.VERSION.SDK_INT;
            if (sysVersion >= 11) {
                setZoomControlGoneX(binding.infoAWebContent.getSettings(), new Object[]{false});
            } else {
                setZoomControlGone(binding.infoAWebContent);
            }
            super.onDestroy();
            binding.infoAWebContent.destroy();
        }
    
        /**
         * 2020-01-03  vic 添加
         *
         * @param view
         * @param args
         */
        public void setZoomControlGoneX(WebSettings view, Object[] args) {
            Class classType = view.getClass();
            try {
                Class[] argsClass = new Class[args.length];
                for (int i = 0, j = args.length; i < j; i++) {
                    argsClass[i] = args[i].getClass();
                }
                Method[] ms = classType.getMethods();
                for (int i = 0; i < ms.length; i++) {
                    if (ms[i].getName().equals("setDisplayZoomControls")) {
                        try {
                            ms[i].invoke(view, false);
                        } catch (Exception e) {
                            e.printStackTrace();
                        }
                        break;
                    }
                }
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    
        public void setZoomControlGone(View view) {
            Class classType;
            Field field;
            try {
                classType = WebView.class;
                field = classType.getDeclaredField("mZoomButtonsController");
                field.setAccessible(true);
                ZoomButtonsController mZoomButtonsController = new ZoomButtonsController(view);
                mZoomButtonsController.getZoomControls().setVisibility(View.GONE);
                try {
                    field.set(view, mZoomButtonsController);
                } catch (IllegalArgumentException e) {
                    e.printStackTrace();
                } catch (IllegalAccessException e) {
                    e.printStackTrace();
                }
            } catch (SecurityException e) {
                e.printStackTrace();
            } catch (NoSuchFieldException e) {
                e.printStackTrace();
            }
        }

当然，最好方法在不需要放大缩小时，不显示该view.

东西这么少，再写点吧。

webView的相关属性设置：

binding.infoAWebContent.getSettings().setSupportZoom(true);
                    binding.infoAWebContent.getSettings().setBuiltInZoomControls(true);
                    binding.infoAWebContent.getSettings().setDisplayZoomControls(false);
                    binding.infoAWebContent.getSettings().setDomStorageEnabled(true);
                    binding.infoAWebContent.loadUrl(mS_url);
                    binding.infoAWebContent.getSettings().setJavaScriptEnabled(true);
                    
           
        binding.infoAWebContent.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
                    binding.infoAWebContent.getSettings().setBuiltInZoomControls(true);
                    binding.infoAWebContent.getSettings().setLoadWithOverviewMode(true);
                    binding.infoAWebContent.getSettings().setDefaultTextEncodingName("UTF-8");

可以很明显看到跟zoom报错相关的属性有：

这三条大概意思：

显示放大缩小的按钮，设置放大缩小的功能

如果保存放大缩小的功能，又不让项目崩溃：
