上显示进度的WebView对话框 [英] show progress dialog on webview

问题描述

在我的Andr​​oid应用程序，我打开webview.I想隐藏，这是获得加载的url，因此默认窗口进度条亘古不变的工作对我来说。

In my android application i am opening a webview.I want to hide url that is getting loaded,so the default window progress bar doesnot work for me.

有没有什么办法比，我可以添加进度对话的WebView。

Is there any way than that i can add progress dialogue on webview.

我使用的是下面的code。

I am using the below code.

 mWebView = (WebView) findViewById(R.id.webview);
     mWebView.getSettings().setJavaScriptEnabled(true); 

     final Activity activity = this; 

     mWebView.setWebChromeClient(new WebChromeClient(){ 

     public void onProgressChanged(WebView view, int progress) { 
     activity.setTitle("Loading..."); 
     activity.setProgress(progress * 100); 
     if(progress == 100) 
     activity.setTitle("My title"); 
     } 
     }); 

     mWebView.loadUrl(Url);
     mWebView.setWebViewClient(new HelloWebViewClient());
    }
    catch(Exception e)
    {
        e.printStackTrace();
    }

}

private class HelloWebViewClient extends WebViewClient {   
    ProgressDialog MyDialog=new ProgressDialog(context);

    public boolean shouldOverrideUrlLoading(WebView view, String url) {    
        MyDialog.show();  
        view.loadUrl(url);  
        return true;  
         }

请分享您宝贵的建议。

推荐答案

如果您通过隐藏应用程序标题安卓主题=@安卓风格/ Theme.NoTitleBar从清单，那么你将不会看到进度条，其中受此code显示在标题：

if you hide application title by "android:theme="@android:style/Theme.NoTitleBar"" from manifest then you won't see progress bar which is being displayed in title by this code:

    this.getWindow().requestFeature(Window.FEATURE_PROGRESS);               
    setContentView(R.layout.main);

// Makes Progress bar Visible
getWindow().setFeatureInt( Window.FEATURE_PROGRESS, Window.PROGRESS_VISIBILITY_ON);

所以，你可以显示进度条一个对话框，像这样的onCreate（）里面的：

So you can show progress bar with a Dialog box like this inside the onCreate():

final Activity activity = this;

final ProgressDialog progressDialog = new ProgressDialog(activity);
progressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
progressDialog.setCancelable(false);

browser.setWebChromeClient(new WebChromeClient() {
    public void onProgressChanged(WebView view, int progress) {
        progressDialog.show();
        progressDialog.setProgress(0);
        activity.setProgress(progress * 1000);

        progressDialog.incrementProgressBy(progress);

        if(progress == 100 && progressDialog.isShowing())
            progressDialog.dismiss();
    }
});
