how to display progress while loading a url to webview in android?

Question

I am loading url into webview:

WebView webview=(WebView)findViewById(R.id.webview);  webview.loadUrl(url); 

It's taking some time to load url, during which it shows a blank screen. I want to display a progress dialog while the url is loading:

ProgressDialog dialog = ProgressDialog.show(this, "HI","Loading......", true); 

However, the above is code is not working. If any have any ideas, please help. Thanks in advance.

set a WebViewClient to your WebView, start your progress dialog on you onCreate() method an dismiss it when the page has finished loading in onPageFinished(WebView view, String url)

import android.app.Activity; import android.app.AlertDialog; import android.app.ProgressDialog; import android.content.DialogInterface; import android.content.Intent; import android.net.Uri; import android.os.Bundle; import android.util.Log; import android.view.Window; import android.webkit.WebSettings; import android.webkit.WebView; import android.webkit.WebViewClient; import android.widget.Toast;  public class Main extends Activity {     private WebView webview;     private static final String TAG = "Main";     private ProgressDialog progressBar;        /** Called when the activity is first created. */     @Override     public void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);          requestWindowFeature(Window.FEATURE_NO_TITLE);          setContentView(R.layout.main);          this.webview = (WebView)findViewById(R.id.webview);          WebSettings settings = webview.getSettings();         settings.setJavaScriptEnabled(true);         webview.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY);          final AlertDialog alertDialog = new AlertDialog.Builder(this).create();          progressBar = ProgressDialog.show(Main.this, "WebView Example", "Loading...");          webview.setWebViewClient(new WebViewClient() {             public boolean shouldOverrideUrlLoading(WebView view, String url) {                 Log.i(TAG, "Processing webview url click...");                 view.loadUrl(url);                 return true;             }              public void onPageFinished(WebView view, String url) {                 Log.i(TAG, "Finished loading URL: " +url);                 if (progressBar.isShowing()) {                     progressBar.dismiss();                 }             }              public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {                 Log.e(TAG, "Error: " + description);                 Toast.makeText(activity, "Oh no! " + description, Toast.LENGTH_SHORT).show();                 alertDialog.setTitle("Error");                 alertDialog.setMessage(description);                 alertDialog.setButton("OK", new DialogInterface.OnClickListener() {                     public void onClick(DialogInterface dialog, int which) {                         return;                     }                 });                 alertDialog.show();             }         });         webview.loadUrl("http://www.google.com");     } } 

your main.xml layout

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"     android:orientation="vertical"     android:layout_width="fill_parent"     android:layout_height="fill_parent"     >     <WebView android:id="@string/webview"         android:layout_width="fill_parent"         android:layout_height="fill_parent"         android:layout_weight="1" /> </LinearLayout>
