推荐答案

默认 WebChromeClient 的嵌入式浏览器实现将丢弃JavaScript警告，你应该重写 WebChromeClient 的实施与你自己的版本，这也可以让你在的地方一个默认的创建自己的自定义提醒，像这样的能力：

The default WebChromeClient implemented by the embedded browser will discard javascript alerts, you should override the WebChromeClient implementation with your own version, this also allows you the ability to create your own custom alerts in place of the default one like so:

browser.setWebChromeClient(new MyWebChromeClient());

...

final class MyWebChromeClient extends WebChromeClient {
    @Override
    public boolean onJsAlert(WebView view, String url, String message, JsResult result) {
        Log.d(LOG_TAG, message);
        new AlertDialog.Builder(view.getContext()).setMessage(message).setCancelable(true).show();
        result.confirm();
        return true;
    }
}
