微信支付宝H5支付二合一

1：支付宝根据官方文档导入最新jar包、mainXml文件中加入支付宝的Activity、混淆文件等等按照官方配置配置即可。

2：注意点（坑）
（1）：如果 WebView需要支持JS之间交互，请把JS代码放在以下代码中，不然会存在调不起来支付三方的H5页面

@Overridepublic void onPageStarted(WebView view, String url, Bitmap favicon) {super.onPageStarted(view, url, favicon);if (Build.VERSION.SDK_INT >= 19) {webView.evaluateJavascript(getJSStr(), new ValueCallback() {@Override public void onReceiveValue(String value) {//js与native交互的回调函数}});}}/*** 加载JS字符串* @return*/private String getJSStr(){String jsStr = "";try {InputStream in = mContext.getAssets().open(BridgeWebView.toLoadJs);byte buff[] = new byte[1024];ByteArrayOutputStream fromFile = new ByteArrayOutputStream();do {int numRead = in.read(buff);if (numRead <= 0) {break;}fromFile.write(buff, 0, numRead);} while (true);jsStr = fromFile.toString();in.close();fromFile.close();} catch (IOException e) {e.printStackTrace();}return jsStr;}

• 拦截支付宝、微信等Url并跳转

@Overridepublic boolean shouldOverrideUrlLoading(final WebView view, String url) {if (url.startsWith("weixin://wap/pay?")) {try {//如果return false  就会先提示找不到页面，然后跳转微信Intent intent = new Intent();intent.setAction(Intent.ACTION_VIEW);intent.setData(Uri.parse(url));startActivity(intent);return true;}catch (Exception e){}}else if (url.contains("alipay")){if (!(url.startsWith("http") || url.startsWith("https"))) {return true;}/*** 推荐采用的新的二合一接口(payInterceptorWithUrl),只需调用一次*/final PayTask task = new PayTask(RechargeH5Activity.this);boolean isIntercepted = task.payInterceptorWithUrl(url, true, new H5PayCallback() {@Overridepublic void onPayResult(final H5PayResultModel result) {// 支付结果返回final String url = result.getReturnUrl();if (!TextUtils.isEmpty(url)) {RechargeH5Activity.this.runOnUiThread(new Runnable() {@Overridepublic void run() {view.loadUrl(url);}});}}});/*** 判断是否成功拦截* 若成功拦截，则无需继续加载该URL；否则继续加载*/if (!isIntercepted) {view.loadUrl(url);}return true;} else{//H5微信支付要用，不然说"商家参数格式有误"final Map headerMap = new HashMap<>();//初始化urlString urlPath = initWebUrl();headerMap.put("Referer",urlPath);view.loadUrl(url,headerMap);}return super.shouldOverrideUrlLoading(view,url);}@Overridepublic void onReceivedSslError(WebView view, SslErrorHandler handler, SslError error) {//此方法是为了处理在5.0以上Htts的问题，必须加上handler.proceed();}});

• 注意重写Client，对Url进行编码

}

• 继承使用

        mWebView.setWebViewClient(new BridgePayWebViewClient(mWebView,RechargeH5Activity.this) {
