WebView of android Control

I found this control is quite useful and can control the progress bar by myself, and the control is very powerful. I will explain it later.

First, a simple

Package com. weizhu. lan. view;

Import com. weizhu. lan. util. MyprogressDialog;

Import android. app. Activity;
Import android. app. AlertDialog;
Import android. content. Context;
Import android. content. Intent;
Import android.net. ConnectivityManager;
Import android. OS. AsyncTask;
Import android. OS. Bundle;
Import android. OS. Handler;
Import android. view. KeyEvent;
Import android. view. Window;
Import android. webkit. WebChromeClient;
Import android. webkit. WebView;
Import android. widget. ProgressBar;

Public class HelpCenter extends Activity {

// 50766649
Private String urlHelp = "http://www.baidu.com ",
Userid = "userid = ";
Private String yqhId;
Private WebView web;
Private Handler hand;
Private ProgressBar pb;
Private MyAsyncTask myAsy;
@ Override
Protected void onCreate (Bundle savedInstanceState ){

Super. onCreate (savedInstanceState );
RequestWindowFeature (Window. FEATURE_NO_TITLE );
SetContentView (R. layout. help_webview );

YqhId = getIntent (). getStringExtra ("yqhId ");

Web = (WebView) findViewById (R. id. help_WebView1 );
Web. getSettings (). setBuiltInZoomControls (true); // you can zoom in or out.
MyAsy = new MyAsyncTask ();
Final String str = urlHelp;
MyAsy.exe cute (str );

}
Class MyAsyncTask extends AsyncTask <String, String, Void> {

@ Override
Protected Void doInBackground (String... params ){
Web. loadUrl (params [0]);
Web. setWebChromeClient (new WebChromeClient (){
@ Override
Public void onProgressChanged (WebView view, int newProgress ){
Super. onProgressChanged (view, newProgress );
Pb. setProgress (newProgress); // it handles the progress bar by itself
}
});
Return null;
}
@ Override
Protected void onPostExecute (Void result ){

}
@ Override
Protected void onPreExecute (){
Pb = (ProgressBar) findViewById (R. id. help_progressBar2 );
Pb. setProgress (0 );
}
}
}
