onJsAlert 没有响应点击后的 Android webview [英] Android webview after onJsAlert not responding taps

问题描述

我已经覆盖了我的 WebChromeClient 的 onJsAlert 行为，例如:

I have override my WebChromeClient's onJsAlert behavior like:

WebChromeClient wvcc = new WebChromeClient() {
            @Override
            public boolean onJsAlert(WebView view, String url, String message, final JsResult result) {
    //...
    return true;
    }
}

我的应用程序成功处理了 Js 警报并抑制了原始警报.但是，在警报事件发生后，我无法再单击 web 视图中网页上的按钮(在列表视图的列表项中).我目前正在使用 jquery mobile 来构建我的网站.

my application successfully handle the Js alerts and suppressed the original alert. However, after the alert event, I can no longer click my buttons(in list-items of listview) on the web page in my webview. I am currently using jquery mobile to build my web.

还有什么我应该注意的吗?

Is there anything else I should aware of?

推荐答案

我刚刚遇到了完全相同的问题.我想生成一个自定义的 android 对话框而不是警报，这是最终的解决方案:

I just faced the exactly same problem. I wanted to generate a custom android dialog instead of the alert, to this is the final solution:

myWebView.setWebChromeClient(new WebChromeClient() {
    @Override
    public boolean onJsAlert(WebView view, final String url, String message,
            JsResult result) {

        AlertDialog.Builder builder = new AlertDialog.Builder(
                MainActivity.this);
        builder.setMessage(message)
                .setNeutralButton("OK", new OnClickListener() {
                    @Override
                    public void onClick(DialogInterface arg0, int arg1) {
                        arg0.dismiss();
                    }
                }).show();
        result.cancel();
        return true;
    }
});

关键是result.cancel();和return true;，我测试了几种组合，唯一没有触发默认JS警报的并且没有导致触摸问题是这种组合

The key is the result.cancel(); and return true;, I tested in several combinations, and the only one that did not fired the default JS alert AND didn't caused the touch problem was this combination
