Question

我使用Webview生成html内容。这是我的问题。当我执行此代码5-6次时，onPageFinished被调用。但是，如果我继续执行此代码，则在某些时候不会调用onPageFinished，也不会调用onReceivedError。有什么想法吗？

                    WebView view = new WebView(getActivity());
                    final PrintManager print = (PrintManager)getActivity().getSystemService(PRINT_SERVICE);

                    view.setWebViewClient(new WebViewClient() {
                        @Override
                        public void onPageFinished(WebView view, String url) {

                            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP)
                                print.print("signups", view.createPrintDocumentAdapter("signups "+new Date()), new PrintAttributes.Builder().build());
                            else
                                print.print("signups", view.createPrintDocumentAdapter(), new PrintAttributes.Builder().build());

                            SnackBarMessages.makeDesign(new Pair<>(MainActivity.ON_SUCCESS_EXPORT, (Object)"Export Completed"), getActivity());
                            ((BasicApp) getActivity().getApplication()).getRepository().setLockExport(false);
                            ((BasicApp) getActivity().getApplication()).getRepository().setLock(false);
                            ProgressDialogExport.this.dismiss();

                        }

                        @Override
                        public void onReceivedError(WebView view, WebResourceRequest request, WebResourceError error) {
                            super.onReceivedError(view, request, error);

                        }
                    });
                    view.loadData("<html></html>","text/html","UTF-8");

多次成功执行后未调用Webview-onPageFinish
