解决h5微信支付跳转

webView.setWebViewClient(new WebViewClient(){
    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) {

        if (url != null && url.startsWith("weixin://wap/pay?")) {

            finish();
            view.getContext().startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(url)));

        }

        return false;
    }

});

要添加请求头

Map extraMap=new HashMap<>();
extraMap.put("referer",getIntent().getStringExtra("referer"));//就是域名，比如：http://www.baidu.com

L.e("tag","获取加载url:"+url);
webviewSetting();
webView.loadUrl(url,extraMap);
