怎么当的WebView加载页面设置不同的标题提示对话框？ [英] how to set different title for alert dialog when WebView page is loaded?

问题描述

我要当的WebView 页面加载，但设置不同的标题警告对话框它不工作。

这里是code片断：

 最后AlertDialog.Builder警报=新AlertDialog.Builder（
        mContext）;
// alert.setTitle（载入中...）;
最后的WebView WV =新的WebView（mContext）;

wv.loadUrl（http://10.0.51.133/androidview/）;
wv.getSettings（）setJavaScriptEnabled（真）。
wv.setVerticalScrollBarEnabled（假）;

WebViewClientLoader装载机=新WebViewClientLoader（警告）;
wv.setWebViewClient（装载机）;
wv.setWebViewClient（新WebViewClient（）{

    @覆盖
    公共无效onPageFinished（web视图查看，字符串URL）{
        // TODO自动生成方法存根
        alert.setTitle（载入中...）;
        super.onPageFinished（查看，网址）;
    }

    @覆盖
    公共无效onPageStarted（web视图查看，字符串URL，
            位图图标）{
        // TODO自动生成方法存根
        alert.setTitle（完成）;
        super.onPageStarted（查看，网址，网站图标）;
    }
}）;

私有类webviewclient扩展WebViewClient {

}

wv.loadUrl（文件：///android_asset/Like.html）;
alert.setView（WV）;

alert.show（）;
 

解决方案

它的检查后，完全work..i上午发布-------

 公共类MyActivity延伸活动{
@覆盖
保护无效的onCreate（包savedInstanceState）{
    super.onCreate（savedInstanceState）;
    的WebView网站=新的WebView（本）;
    web.setWebViewClient（新WebViewClient（）{

        @覆盖
        公共无效onLoadResource（web视图查看，字符串URL）{
            super.onLoadResource（查看，网址）;
        }

        @覆盖
        公共无效onPageFinished（web视图查看，字符串URL）{
            super.onPageFinished（查看，网址）;
            alert.setTitle（的页面已完成）;
        }

        @覆盖
        公共无效onPageStarted（web视图查看，字符串URL，位图图标）{
            super.onPageStarted（查看，网址，网站图标）;
            alert.setTitle（页面入门）;
        }

    }）;
    web.setWebChromeClient（新WebChromeClient（）{

    }）;
    web.loadUrl（http://www.google.com）;
    建设者=新AlertDialog.Builder（本）;
    builder.setView（网络）;
    builder.setTitle（载入中...）;
    警报= builder.create（）;
    alert.show（）;
}
AlertDialog警报;
生成器生成器;
@覆盖
保护无效的onDestroy（）{
    super.onDestroy（）;

}

@覆盖
保护无效的onPause（）{

}
 

}

，然后将其转变为

I want to set different title for alert dialog when WebView page is loaded but its not working.

        @Override
        public void onLoadResource(WebView view, String url) {
            super.onLoadResource(view, url);

        @Override
        public void onPageFinished(WebView view, String url) {
            super.onPageFinished(view, url);

        @Override

            super.onPageStarted(view, url, favicon);
            alert.setTitle("Pages Started");
        }

    });
    web.setWebChromeClient(new WebChromeClient(){

    builder.setView(web);
    builder.setTitle("Loading...");
    alert=builder.create();
