  • WebView的resource response

 

//                    Uri requestUri = request.getRequestUrl();
//                    String urltrytoload = requestUri.toString();
//                    if (CheckNetworkStatus.isNetworkConnectedInternet(getContext()) == false) {
////                        HiLog.info(mLogLabel, webView.getComponentDescription().toString()+"webViewInFocus ResourceResponse processResourceRequest NOT   %{public}s,编号为%{public}d", requestUri.toString(), 123456);
//                        String response = "";
////                            "<html>\n" +
////                            "<center><div style=\"width:270px;height:60px;border:0px solid grey;\">"+
////                            "<p><font size=\"3\" face=\"arial\" color=\"red\"><center>网址不可达，请检查网络状态！</center></font></p>"+
////                            "</div></center>"+
////                            "<html>";
//                        ResourceResponse webResourceResponse = new ResourceResponse("text/html", new ByteArrayInputStream(response.getBytes()), "utf-8");
//                        HiLog.error(HLQQ, webView.getComponentDescription().toString()+"webViewInFocus webResourceResponse   %{public}s,编号为%{public}d", webResourceResponse.getCharset() + webResourceResponse.getReason(), 123480);
//
////                        threadtoupdateUi(1);
//
//                        return webResourceResponse;
//
//
//                    } else {
//                        HiLog.error(HLQQ, webView.getComponentDescription().toString()+"webViewInFocus ResourceResponse processResourceRequest YES %{public}s,编号为%{public}d", requestUri.toString(), 123457);
//                        return super.processResourceRequest(webView, request);
//                    }



  • 拦截并处理本地资源

                //此段代码有用，用于处理本地文件。不要删除！

//            @Override
//            public ResourceResponse processResourceRequest(WebView webview, ResourceRequest request) {
//
//
//                final String authority = "lingxihelp.com";
//                final String rawFile = "/rawfile/";
//                final String local = "/local/";
//                Uri requestUri = request.getRequestUrl();
//                if (authority.equals(requestUri.getDecodedAuthority())) {
//                    String path = requestUri.getDecodedPath();
//                    if (TextTool.isNullOrEmpty(path)) {
//                        return super.processResourceRequest(webview, request);
//                    }
//                    if (path.startsWith(rawFile)) {
//                        // 根据自定义规则访问资源文件
//                        String rawFilePath = "entry/resources/rawfile/" + path.replace(rawFile, "");
//                        String mimeType = URLConnection.guessContentTypeFromName(rawFilePath);
//                        try {
//                            Resource resource = getResourceManager().getRawFileEntry(rawFilePath).openRawFile();
//                            ResourceResponse response = new ResourceResponse(mimeType, resource, null);
//                            return response;
//                        } catch (IOException e) {
//                            HiLog.info(mLogLabel, "open raw file failed");
//                        }
//                    }
//                    if (path.startsWith(local)) {
//                        // 根据自定义规则访问本地文件
//                        String localFile = getContext().getFilesDir() + path.replace(local, "/");
//                        HiLog.info(mLogLabel, "open local file " + localFile);
//                        File file = new File(localFile);
//                        if (!file.exists()) {
//                            HiLog.info(mLogLabel, "file not exists");
//                            return super.processResourceRequest(webview, request);
//                        }
//                        String mimeType = URLConnection.guessContentTypeFromName(localFile);
//                        try {
//                            InputStream inputStream = new FileInputStream(file);
//                            ResourceResponse response = new ResourceResponse(mimeType, inputStream, null);
//                            return response;
//                        } catch (IOException e) {
//                            HiLog.info(mLogLabel, "open local file failed");
//                        }
//                    }
//                }
//                return super.processResourceRequest(webview, request);
//            }

 

  • 以schedule方式run

//                        HiLog.warn(HLQQ, "++++++++++updateprogress");
//                        progress2 = newValue;
//                        timerTask2 = new TimerTask() {
//                            @Override
//                            public void run() {
//                                myEventHandlerBoundwithmainrunner.sendEvent(12);
//                            }
//                        };
//                        timer2 = new Timer();
//                        timer2.schedule(timerTask2, 1000, 1000);

 

  • ClipBoard

        SystemPasteboard pasteboard = SystemPasteboard.getSystemPasteboard(this);
        PasteData pasteData = new PasteData();
        pasteData.addTextRecord("转自外媒-:" + wv.getTitle() + wv.getFirstRequestUrl());
//        PacMap pacMap = new PacMap();
//        pacMap.putString("ADDITION_KEY", "ADDITION_VALUE_OF_TEXT");
//        pasteData.getProperty().setAdditions(pacMap);
//        pasteData.getProperty().setTag("USER_TAG");
//        pasteData.getProperty().setLocalOnly(true);
        pasteboard.setPasteData(pasteData);
//        pasteData = null;


  • 启动各种各样的Intent


        //        Intent intent = new Intent();
//        Operation operation = new Intent.OperationBuilder().withAction("android.intent.action.GET_CONTENT").build();
//        intent.addFlags(Intent.FLAG_NOT_OHOS_COMPONENT);
//        intent.setType("text/plain");
//        intent.setOperation(operation);
//        startAbility(intent);

//        Intent intent = new Intent();
//        Set<String> entities = new HashSet<>();
//        entities.add("android.intent.category.LAUNCHER");
//        Operation operation = new Intent.OperationBuilder()
//                .withDeviceId("")
//                .withBundleName("com.tencent.mm")

//                .withFlags(Intent.FLAG_NOT_OHOS_COMPONENT)
//                .withEntities(entities)
//                .build();
//        intent.setOperation(operation);
//        startAbility(intent);


//        IBundleManager manager = this.getBundleManager();
//        try {
//            System.out.println("QQQQQQQQQQQQQQQQQQQQQQQQQQQ"+manager.getAllFormsInfo().toArray().toString());
//        } catch (RemoteException e) {

//        Operation operation = new Intent.OperationBuilder()
//                .withDeviceId("")
////                IT's ok'
////                .withBundleName("com.autonavi.minimap")
////                .withAbilityName("com.autonavi.map.activity.SplashActivity")
////                .withBundleName("com.sina.weibo")
//                //这是启动页
////                .withAbilityName("com.sina.weibo.SplashActivity")
//                //这是功能页
////                .withAbilityName("com.sina.weibo.MainTabActivity")
//                //这是写微博的地方。
////                .withAbilityName("com.sina.weibo.composerinde.OriginalComposerActivity")
//                .withAction("android.intent.action.MAIN")

//                .build();
//        intent.setOperation(operation);
//        startAbility(intent);

//        outsideIntent = new Intent();
////        intent.setType("text/plain");
//        Set<String> entities = new HashSet<>();

//                .build();
//        outsideIntent.setOperation(operation);

  • PopDiglog版toast

private void manyToast(String textshown) {

    DirectionalLayout webToastLayoutforsoftkeyforward = (DirectionalLayout) LayoutScatter.getInstance(getContext())
            .parse(ResourceTable.Layout_web_toast_xward, null, false);
    ((Text) webToastLayoutforsoftkeyforward.getComponentAt(0)).setText(textshown);
    ((Text) webToastLayoutforsoftkeyforward.getComponentAt(0)).setFont(Font.DEFAULT_BOLD);
    webToastLayoutforsoftkeyforward.setBackground(elementToast);
    PopupDialog toastMadeMyself = new PopupDialog(getContext(), networkNotAvailablePage);
    toastMadeMyself.setCustomComponent(webToastLayoutforsoftkeyforward);
    toastMadeMyself.setDuration(1000);
    toastMadeMyself.setCornerRadius(160);
    toastMadeMyself.showOnCertainPosition(LayoutAlignment.TOP, 0, 320);
    toastMadeMyself.show();
}

  • 各种更新UI的方法

调用主UI线程异步和延时异步、定时间隔、通过进程间通讯事件
