I'm displaying a webpage in a WebView and on the webpage, there is a button. When you click the button, a confirmation dialog is supposed to popup, but it doesn't show in my WebView. It does popup if I go to the same webpage in the android browser. Anyone know how to handle popup dialogs coming from a webpage inside your WebView?

推荐答案

好了，找到了答案，就是这样！

Ok, found the answer and here it is!

为了处理弹出确认从网页进来你的web视图，你需要重写onJsConfirm方法WebChromeClient显示弹出作为一个Android警报对话框。这里是code这样做。

In order to handle a popup confirmation coming from a webpage in your WebView, you need to override the onJsConfirm method in WebChromeClient to display the popup as an Android Alert dialog. Here is the code to do so.

final Context myApp = this; 
final class MyWebChromeClient extends WebChromeClient {
    @Override
    public boolean onJsConfirm(WebView view, String url, String message, final JsResult result) {
        new AlertDialog.Builder(myApp)
        .setTitle("App Titler")
        .setMessage(message)
        .setPositiveButton(android.R.string.ok,
                new DialogInterface.OnClickListener()
        {
            public void onClick(DialogInterface dialog, int which)
            {
                result.confirm();
            }
        })
        .setNegativeButton(android.R.string.cancel,
                new DialogInterface.OnClickListener()
        {
            public void onClick(DialogInterface dialog, int which)
            {
                result.cancel();
            }
        })
        .create()
        .show();

        return true;
    }
}

不要忘记设置你的WebChromeClient在你的web视图...

Don't forget to set your WebChromeClient in your WebView...

    mWebView.setWebChromeClient(new MyWebChromeClient());

请注意...这不是我的code，但我发现它和它的作品完美地处理JavaScript的确认对话框中的WebView！

Note.. this isn't my code, but I found it and it works perfectly for handling javascript confirmation dialogs in a WebView!

干杯！
