Webview工具類

在項目開發過程當中，免不了要進行混合開發，也就是常見的web混合開發，記錄一下項目中經常使用的部分代碼。

1. webSetting常見屬性設置

mWebView.setScrollBarStyle(View.SCROLLBARS_OUTSIDE_OVERLAY);
        //WebView屬性設置！！！
        WebSettings settings = mWebView.getSettings();
        //設置加載js
        settings.setJavaScriptEnabled(true);
        settings.setAllowFileAccess(true);
        settings.setCacheMode(WebSettings.LOAD_DEFAULT);
        settings.setDomStorageEnabled(true);
        settings.setUseWideViewPort(true);
        settings.setLayoutAlgorithm(WebSettings.LayoutAlgorithm.SINGLE_COLUMN);
        settings.setLoadWithOverviewMode(true);
        settings.setJavaScriptCanOpenWindowsAutomatically(true);
        settings.setDatabaseEnabled(true);

        //webview在安卓5.0以前默認容許其加載混合網絡協議內容
        // 在安卓5.0以後，默認不容許加載http與https混合內容，須要設置webview容許其加載混合網絡協議內容
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            mWebView.getSettings().setMixedContentMode(WebSettings.MIXED_CONTENT_ALWAYS_ALLOW);
        }

2. webclient

mWebView.setWebChromeClient(new MyWebChromeClient());

        mWebView.setWebViewClient(new WebViewClient() {
            @Override
            public boolean shouldOverrideUrlLoading(WebView view, String url) {
               
                Log.i("網頁攔截中加載的url:", url);
                view.loadUrl(url);
                return super.shouldOverrideUrlLoading(view, url);
            }

            @Override
            public void onPageStarted(WebView view, String url, Bitmap favicon) {
                super.onPageStarted(view, url, favicon);
            }

            @Override
            public void onPageFinished(WebView view, String url) {
                super.onPageFinished(view, url);


            }
        });
        
        
class MyWebChromeClient extends WebChromeClient {

        @Override
        public void onProgressChanged(WebView view, int newProgress) {
            if (newProgress == 100) {
                mProgressBar.setVisibility(View.GONE);
            } else {
                mProgressBar.setVisibility(View.VISIBLE);
                mProgressBar.setProgress(newProgress);
            }

        }

        @Override
        public void onReceivedTitle(WebView view, String webtitle) {
            super.onReceivedTitle(view, webtitle);
            LogUtils.logi("網頁標題:" + webtitle);
            if (!TextUtils.isEmpty(webtitle)) {
                mTitle.setTitle(false, null, webtitle);
            } else {
                mTitle.setTitle(false, null, "提現");
            }


        }

        //Android 5.0 及以上 必須重寫此方法
        @RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)
        @Override
        public boolean onShowFileChooser(WebView webView, ValueCallback<Uri[]> filePathCallback, FileChooserParams fileChooserParams) {
            boolean fromCamera = fileChooserParams.isCaptureEnabled();
            String[] acceptTypes = fileChooserParams.getAcceptTypes();
            if (acceptTypes != null && acceptTypes.length > 0) {

                boolean isImage = false;
                for (String acceptType : acceptTypes) {
                    if (acceptType.contains("image")) {
                        isImage = true;
                        break;
                    }
                }
                if (isImage) {//處理圖片

                        if (captureImageFromCamera(WebViewActivity.this, imageUri)) {
                            WebViewActivity.this.filePathCallback = filePathCallback;//暫存，用於拍完照片後回調H5
                            return true;//返回true表示APP處理文件選擇
                        }
                    }
                }


                boolean isVideo = false;
                for (String acceptType : acceptTypes) {
                    if (acceptType.contains("video")) {
                        isVideo = true;
                        break;
                    }
                }
                if (isVideo) {//處理視頻
                    if (fromCamera) {//只處理拍攝視頻
                        if (captureVideoFromCamera(WebViewActivity.this, imageUri)) {
                            WebViewActivity.this.filePathCallback = filePathCallback;//暫存，用於拍攝完視頻後回調H5
                            return true;//返回true表示APP處理文件選擇
                        }
                    }
                }
            }
            return super.onShowFileChooser(webView, filePathCallback, fileChooserParams);
        }

        //Android 5.0 如下 必須重寫此方法

                    if (captureVideoFromCamera(WebViewActivity.this, imageUri)) {
                        WebViewActivity.this.uploadFile = uploadFile;//暫存，用於拍攝完視頻後回調H5

                }
            }
        }

3. js注入
   爲了偷個懶，方便方便webview的js操做，特地用了以下的第三方，目前在使用過程當中還未發現大問題，by the way,ios也是通用的。

//webview jsbridge
    implementation 'com.github.wendux:WebViewJavascriptBridge:master-SNAPSHOT'
    compile('com.github.gzu-liyujiang.AndroidPicker:WheelPicker:1.5.6') {
        exclude group: 'com.android.support'
    }
複製代碼

mWebView.registerHandler("testObjcCallback", (WVJBWebView.WVJBHandler) (data, callback) -> {
            callback.onResult(data);
            Log.d("wvjsblog", "Java Echo called with: " + data.toString());
            //此到處理data回調的結果
        });
        
複製代碼

4. 文件下載

/** * 下載文件監聽 跳轉瀏覽器下載 * * @param mWebView */
    public static void addDownLoadListener(Activity activity, WVJBWebView mWebView) {
        mWebView.setDownloadListener((url, userAgent, contentDisposition, mimetype, contentLength) -> {
            if (!TextUtils.isEmpty(url)) {
                downloadByBrowser(activity, url);
            }
        });
    }
    
//跳轉到外部瀏覽器進行下載
    public static void downloadByBrowser(Activity activity, String url) {
        Intent intent = new Intent(Intent.ACTION_VIEW);
        intent.addCategory(Intent.CATEGORY_BROWSABLE);
        intent.setData(Uri.parse(url));
        activity.startActivity(intent);
    }

5. 加載的url歷史堆棧信息（跨域的url）
   這段代碼主要是處理跨域後後到以前網頁的歷史瀏覽信息

/** * 加載的url歷史堆棧信息 * * @param loadHistoryUrls：url數組信息 * @param mWebView * @param activity * @param isMain:是否爲首頁的tab頁面 */
    public static void receiverGoBack(ArrayList<String> loadHistoryUrls, WVJBWebView mWebView, Activity activity, boolean isMain, ImageView imageView) {
        //過濾是否爲重定向後的連接
        LogUtils.loge("網頁攔截中加載的url歷史堆棧信息:" + loadHistoryUrls.toString());
        if (loadHistoryUrls.size() > 1 && !ConfigUtil.H5Pre.contains(loadHistoryUrls.get(loadHistoryUrls.size() - 1))) {
            if (loadHistoryUrls.size() > 2) {
                //移除加載棧中的最後兩個連接
                loadHistoryUrls.remove(loadHistoryUrls.get(loadHistoryUrls.size() - 1));
                loadHistoryUrls.remove(loadHistoryUrls.get(loadHistoryUrls.size() - 1));
            }
            if (loadHistoryUrls.size() > 1) {
                //移除加載棧中的最後一個連接
                loadHistoryUrls.remove(loadHistoryUrls.get(loadHistoryUrls.size() - 1));
            }
            LogUtils.loge("攔截中後退的url歷史記錄" + loadHistoryUrls.toString());
            //加載重定向以前的頁
            if (isMain) {
                if (loadHistoryUrls.size() == 1) {
                    imageView.setVisibility(View.INVISIBLE);
                }
            }
            mWebView.loadUrl(loadHistoryUrls.get(loadHistoryUrls.size() - 1));
        } else {
            activity.finish();

        }
    }
    
  public static void onPressGoBack(ArrayList<String> loadHistoryUrls, WVJBWebView mWebView, ImageView imageView, Activity activity) {

        //過濾是否爲重定向後的連接
        LogUtils.loge("網頁攔截中加載的url歷史堆棧信息:" + loadHistoryUrls.toString());
        if (loadHistoryUrls.size() > 1 && !ConfigUtil.H5Pre.contains(loadHistoryUrls.get(loadHistoryUrls.size() - 1))) {
            if (loadHistoryUrls.size() > 2) {
                //移除加載棧中的最後兩個連接
                loadHistoryUrls.remove(loadHistoryUrls.get(loadHistoryUrls.size() - 1));
                loadHistoryUrls.remove(loadHistoryUrls.get(loadHistoryUrls.size() - 1));
            }
            if (loadHistoryUrls.size() > 1) {
                //移除加載棧中的最後一個連接
                loadHistoryUrls.remove(loadHistoryUrls.get(loadHistoryUrls.size() - 1));
            }
            LogUtils.loge("攔截中後退的url歷史記錄" + loadHistoryUrls.toString());
            //加載重定向以前的頁
            if (loadHistoryUrls.size() == 1) {
                imageView.setVisibility(View.INVISIBLE);
            }
            mWebView.loadUrl(loadHistoryUrls.get(loadHistoryUrls.size() - 1));
        } else {
            if ((System.currentTimeMillis() - exitTime) > 2000) {
                ToastUtil.showToast("再按一次退出程序");
                exitTime = System.currentTimeMillis();
            } else {
                activity.finish();
