webView.setWebChromeClient(new WebChromeClient() {
//获取网页的标题
@Override
public void onReceivedTitle(WebView view, String title) {
    super.onReceivedTitle(view, title);
    setTitle(title);
}
//重写alert弹框
@Override
public boolean onJsAlert(WebView view, String url, final String message, JsResult result) {
    WjLog.d("main", "onJsAlert:" + message);
    runOnUiThread(new Runnable() {
            @Override
            public void run() {
                new AlertDialog.Builder(WebViewActivity.this)
                        .setTitle("提示")
                        .setMessage(message)
                        .setPositiveButton("确定", new DialogInterface.OnClickListener() {
                            @Override
                            public void onClick(DialogInterface dialog, int which) {
                                //webView.reload();//重写刷新页面
                    }
                }).show();
            }
        });
        result.confirm();//这里必须调用，否则页面会阻塞造成假死
        return true;
