进度对话框不能停止 [英] progress dialog could not stop

问题描述

我是新来android.I正在使用进度对话框，在我的应用程序，但它不能stop.In我的应用程序，我使用webview.In第一次活动我有连接button.In第二个活动连接到Facebook，code是available.In次活动code：

 公共无效的onCreate（捆绑savedInstanceState）{
    super.onCreate（savedInstanceState）;
    的setContentView（R.layout.facebook）;
    wvFacebook.setWebViewClient（新MyWebViewClient（））;
    wvFacebook.loadUrl（strFacebook）;
}私有类MyWebViewClient扩展WebViewClient
{
    公共布尔shouldOverrideUrlLoading（的WebView视图，字符串URL）
    {
        view.getSettings（）setJavaScriptEnabled（真）。
        view.loadUrl（URL）;
        返回true;
    }    @覆盖
    公共无效onPageStarted（的WebView视图，字符串URL，位图图标）{        super.onPageStarted（查看，网址，图标）;
        prDialog = ProgressDialog.show（的getParent（），进行中，加载中，请稍候......）;
    }    @覆盖
    公共无效onPageFinished（的WebView视图，字符串URL）{
        Log.e（身份，叫......）;
        super.onPageFinished（查看，网址）;
        prDialog.dismiss（）;
        Log.e（身份，调用next ......）;
    }
}
 

当连接按钮点击第二项活动将被执行并获得Facebook的page.But进度对话框停不下来。

解决方案

  @覆盖
        公共无效onPageFinished（的WebView视图，字符串URL）{            尝试{
                    如果（prDialog.isShowing（）|| prDialog！= NULL）{
                        prDialog.dismiss（）;
                        prDialog = NULL; / *** ***添加/
                    }                    }赶上（例外的例外）{
                        exception.printStackTrace（）;
                    }            }
        }

    wvFacebook.loadUrl(strFacebook);
} 

private class MyWebViewClient extends WebViewClient 
{            
    public boolean shouldOverrideUrlLoading(WebView view, String url) 
    {
        view.getSettings().setJavaScriptEnabled(true);
        view.loadUrl(url);
        return true;
    }

    @Override
    public void onPageStarted(WebView view, String url, Bitmap favicon) {

        super.onPageStarted(view, url, favicon);
        prDialog = ProgressDialog.show(getParent(), "In progress", "Loading, please wait...");
    }

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

        super.onPageFinished(view, url);

                        prDialog.dismiss();
                        prDialog= null; /*** Add ***/
