WebView阻止弹出窗口？

Question

我正在使用WebView浏览pesopay.com，并且可以正常运行，除非按下提交按钮时。 使用谷歌浏览器之类的互联网浏览器会显示一个弹出窗口，确认您填写的信息。 但是在我的Android WebView当我按下“提交”按钮时没有任何反应。 我认为是因为未启用WebView来显示弹出窗口。

谁能指出我有什么不对？

这是我的活动：

public class PaymentActivity extends Activity {

String amount1;     
    @SuppressLint("SetJavaScriptEnabled")
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.payment);

         Bundle extras = getIntent().getExtras(); 
            if(extras !=null)
            {
                amount1 = extras.getString("amount1");

            }

        WebView web = (WebView) findViewById(R.id.web1);
        web.getSettings().setJavaScriptEnabled(true);
        web.loadUrl("javascript:window.onload = function(){setValue(\""+ amount1 +"\");};");
        web.loadUrl("file:///android_asset/www/index.html");   
    }    
}

Answer 1

如果我说对了，则需要使用JavaScriptInterface从Android调用JavaScript函数。

检查此链接可能会帮助您：

http://www.codeproject.com/Articles/392603/Android-addJavaScriptInterface

或检查一些网络设置： http : //developer.android.com/reference/android/webkit/WebSettings.html#setSupportMultipleWindows%28boolean

尝试将这段代码放在onCreate（）中

        webView.getSettings().setPluginsEnabled(true);
        webView.getSettings().setAllowFileAccess(true);
        webView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);

Answer 2

在Webview中负责对话框的功能是WebChromeClient的onJsAlert。

这是示例代码

  public class MyWebChromeClient extends WebChromeClient {
    @Override
    public boolean onJsAlert(WebView view, String url, String message, JsResult jsResult) {
        // you can create your own dialog here or just return true for no pop up. 
        return true;
    }
}

并将其添加到您的网络视图：

MyWebChromeClient myWebChromeClient = new MyWebChromeClient();
webView.setWebChromeClient(myWebChromeClient);
