我使用进度对话框显示进度的同时加载网页，但有时不能正常工作。进度对话框永远不会被解雇，虽然加载页面。

我添加进度条是这样

 公共布尔shouldOverrideUrlLoading（web视图查看，字符串URL）{
    //添加进度对话框
}

公共无效onPageFinished（web视图查看，字符串URL）{
    如果（progressdialog.isShowing（））
       progressdialog.dismiss（）; //驳回进步，但有时从来没有驳回
}
 

解决方案

android_dev，使用一个处理器

 公共无效onPageFinished（web视图查看，字符串URL）
    {
    handler.sendEmptyMessage（0）;
    }

    处理程序处理程序=新的处理程序（）{
      @覆盖
      公共无效的handleMessage（信息MSG）{
     如果（progressdialog.isShowing（）|| progressdialog！= NULL）
     progressdialog.dismiss（）;
     progressdialog = NULL;
      }
    }
 

＆放大器;你做！

I am using Progress Dialog to show progress while loading web page, but sometimes it does not work properly. Progress Dialog never get dismissed though page is loaded.

I have added Progress Bar like this

public boolean shouldOverrideUrlLoading(WebView view, String url) {
    //Added progress dialog
}

public void onPageFinished(WebView view, String url) {
    if(progressdialog.isShowing())
       progressdialog.dismiss(); //Dismissed the progress, but sometimes never dismiss it
}

android_dev , Use a handler

    public void onPageFinished(WebView view, String url) 
    { 
    handler.sendEmptyMessage(0);
    }

    Handler handler = new Handler() {
      @Override
      public void handleMessage(Message msg) {
     if(progressdialog.isShowing() || progressdialog!=null)
     progressdialog.dismiss();
     progressdialog=null;
      }
    }

& you are done!
