封装浏览器，隐藏工具栏后无法下载附件

Question

做了一个客户端，把浏览器封装
package com.easymorse;import android.app.Activity;
import android.os.Bundle;
import android.webkit.WebView;
import android.webkit.WebViewClient;public class helloWebView extends Activity {
WebView wv;@Override
public void onCreate(Bundle icicle) {
  super.onCreate(icicle);
  setContentView(R.layout.main);  wv = (WebView) findViewById(R.id.wv1);
  wv.loadUrl("http://wangjun.easymorse.com/");
  wv.setWebViewClient(new WebViewClientDemo());}private class WebViewClientDemo extends WebViewClient {
  @Override
  // 在WebView中而不是默认浏览器中显示页面
  public boolean shouldOverrideUrlLoading(WebView view, String url) {
   view.loadUrl(url);
   return true;
  }
}
}
本段代码去掉可以下载附件  wv.setWebViewClient(new WebViewClientDemo());
否则不可以，请高手支招

Answer 1

试试 
webView.setDownloadListener(new DownloadListener() {
                        public void onDownloadStart(String url, String userAgent,
                                        String contentDisposition, String mimetype,
                                        long contentLength) {
                                //实现下载的代码
                                                      Uri uri = Uri.parse("http://10.10.10.173:8080/1/1.apk");
                       Intent intent = new Intent(Intent.ACTION_VIEW,uri);
                                startActivity(intent);
                        }
                });
