Add a Progress Bar in WebView

I have added few lines in your code and now its working fine with progress bar.

        getWindow().requestFeature(Window.FEATURE_PROGRESS);
        setContentView(R.layout.main );
        // Makes Progress bar Visible
        getWindow().setFeatureInt( Window.FEATURE_PROGRESS, Window.PROGRESS_VISIBILITY_ON);

        webview = (WebView) findViewById(R.id.webview);
        webview.setWebChromeClient(new WebChromeClient() {
            public void onProgressChanged(WebView view, int progress)   
            {
                //Make the bar disappear after URL is loaded, and changes string to Loading...
                setTitle("Loading...");
                setProgress(progress * 100); //Make the bar disappear after URL is loaded
     
                // Return the app name after finish loading
                if(progress == 100)
                   setTitle(R.string.app_name);
                }
            });
        webview.setWebViewClient(new HelloWebViewClient());
        webview.getSettings().setJavaScriptEnabled(true);
        webview.loadUrl("http://www.google.com");

Progress bar for internal links of a WebView in Android Studio

Instead of a Spinner progress bar, you can use horizontal bar by changing the style.

<ProgressBar
        style="?android:attr/progressBarStyleHorizontal"
        --- other attributes here ---
         />

Place this horizontal progress bar on the top of the webview similar to the image below.

Progress bar mock up

Additionally, by setting chromeWebClient to the webview and overriding onProgressChanged method we can get the progress of the page loading which can be set to the horizontal progress bar.

webView.setWebChromeClient(new WebChromeClient() {
    public void onProgressChanged(WebView view, int newProgress) {
       progressBar.setProgressCompat(newProgress, true)
    }
});

How to display a progress bar when WebView loads a URL, in Android ？

try this code... you need webChoromeClient to track the webview load progress...

webView.setWebChromeClient(new WebChromeClient() {
public void onProgressChanged(WebView view, int progress) {
    progressBar.setProgress(progress);
    if (progress == 100) {
        progressBar.setVisibility(View.GONE);

    } else {
        progressBar.setVisibility(View.VISIBLE);

    }
 }
});

Replace your webview client with this code....

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

how to show progress bar on webview?

Try this:

getWindow().requestFeature(Window.FEATURE_PROGRESS);

WebView mWebView = (WebView) findViewById(R.id.mywebview);

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);

Show a progressbar on top while loading webview app

You create MyWebChromeClient

public class MyWebChromeClient extends WebChromeClient {
private ProgressListener mListener;

public MyWebChromeClient(ProgressListener listener) {
    mListener = listener;
}

@Override
public void onProgressChanged(WebView view, int newProgress) {
    mListener.onUpdateProgress(newProgress);
    super.onProgressChanged(view, newProgress);
}

public interface ProgressListener {
    public void onUpdateProgress(int progressValue);
}
}

in Your MainActivity

public class MainActivity extends AppCompatActivity implements MyWebChromeClient.ProgressListener{
private WebView mWebView;
private ProgressBar mProgressBar;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    mWebView = (WebView) findViewById(R.id.webView);
    WebSettings webSettings = mWebView.getSettings();
    webSettings.setJavaScriptEnabled(true);

    // add progress bar
    mProgressBar = (ProgressBar) findViewById(R.id.progressBar);
    mWebView.setWebChromeClient(new MyWebChromeClient(this));
    mWebView.setWebViewClient(new WebViewClient() {

        public boolean shouldOverrideUrlLoading(WebView view, String url) {

            view.loadUrl(url);

            return true;
        }

        @Override
        public void onPageStarted(WebView view, String url, Bitmap favicon) {
            super.onPageStarted(view, url, favicon);
            mProgressBar.setVisibility(View.VISIBLE);
        }

        @Override
        public void onPageFinished(WebView view, String url) {
            super.onPageFinished(view, url);
            mProgressBar.setVisibility(View.GONE);

        }

    });

}

@Override
public void onUpdateProgress(int progressValue) {
    mProgressBar.setProgress(progressValue);
    if (progressValue == 100) {
        mProgressBar.setVisibility(View.INVISIBLE);
    }
}
}

in activity_main.xml

<RelativeLayout
    android:id="@+id/relative_web_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <ProgressBar
        android:id="@+id/progressBar"
        style="?android:attr/progressBarStyleHorizontal"
        android:layout_width="fill_parent"
        android:layout_height="@dimen/progress_bar_height"
        android:progressDrawable="@drawable/bg_progress_bar_webview" />

    <WebView
        android:id="@+id/webView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_below="@+id/progressBar" />
</RelativeLayout>

in drawable create bg_progress_bar_webview.xml 

 <?xml version="1.0" encoding="utf-8"?>
 <layer-list xmlns:android="http://schemas.android.com/apk/res/android" >

<item
    android:id="@android:id/background"
