Question

我在webview中加载检查字符串

String Check = "<html><body><form action=\"https://sandbox.google.com/checkout/api/checkout/v2/checkoutForm/Merchant/**ID**\" id=\"BB_BuyButtonForm\" method=\"" +
            "post\" name=\"" +"BB_BuyButtonForm\" target=\"_top\">"
            +"<input name=\"item_name_1\" type=\"hidden\" value=\"Carbon Emission\"/>"
            +"<input name=\"item_description_1\" type=\"hidden\" value=\"Pay for carbon emission. \"/>"
            +"<input name=\"item_quantity_1\" type=\"hidden\" value=\"1\"/>"
            +"<input name=\"item_price_1\" type=\"hidden\" value=\"ffff\"/>"
            +"<input name=\"item_currency_1\" type=\"hidden\" value=\"USD\"/>"
            +"<input name=\"_charset_\" type=\"hidden\" value=\"utf-8\"/>"
            +"<input alt=\"\" src=\"https://sandbox.google.com/checkout/buttons/buy.gif?merchant_id=**ID**&amp&w=117&amp&h=48&amp&style=trans&amp&variant=text&amp&loc=en_US\" type=\"Button\"/>"
            +"</form></body></html>";

然后我将检查字符串加载到webview

        webview.loadData(Check, "text/html", "UTF_8");

显示白屏

非常感谢Nappy和Sandy。

最后我解决了我的问题。这是因为安全网址https。这不会直接在webview中运行所以我们必须避免ssl错误

webview.setWebViewClient(new WebViewClient(){

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

        @Override
        public void onReceivedSSLError(WebView view, int errorCode,
                String description, String failingUrl) {
            super.onReceivedError(view, errorCode, description, failingUrl);                 
      view.proceed();
        }

    });

Answer 2

创建类如下

import android.webkit.WebView;

import android.webkit.WebViewClient;

public class HelloWebViewClient extends WebViewClient {

@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}

}
然后在webView.setWebViewClient(new HelloWebViewClient());

之后添加此语句webview.loadUrl(authUrl);

您可能想要更改

setInitialScale（1）;

到

setInitialScale（100）;

因为参数需要百分之一的价值。

Web视图未加载HTML内容
