的WebView阻止弹出窗口?(WebView blocking pop up windows?)

2019-06-26 18:30发布

我使用WebView浏览pesopay.com和它工作正常,除了当我按下提交按钮。 使用互联网浏览器如谷歌Chrome浏览器将显示一个弹出窗口,它确认您填写的信息。 但是,在我的Android WebView什么都没有发生,当我按下提交按钮。 我想是因为WebView未启用显示一个弹出窗口。

任何人都可以点我有什么不好?

这里是我的活动:

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");   
    }    
}

我的网页:

Answer 1:

如果我得到正确的,你需要使用JavaScriptInterface针对Android调用JavaScript函数。

检查此链接可以帮助你:

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

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

尝试把这个代码的onCreate()

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


Answer 2:

它负责在网页视图对话框的功能是onJsAlert WebChromeClient的。

下面是示例代码

  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;
    }
}

并添加到您的网页流量:

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