	private FrameLayout frameLayout;
	
	@SuppressLint("SetJavaScriptEnabled")
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		
		frameLayout = (FrameLayout) findViewById(R.id.frameLayout);
		
		progressBar = (ProgressBar) findViewById(R.id.progressBar);
		progressBar.setMax(100);
		
		webView = (WebView) findViewById(R.id.webView);
		webView.setWebViewClient(new HelpClient());
		webView.setWebChromeClient(new WebChromeClient() {
			@Override
			public void onProgressChanged(WebView view, int progress) {
				frameLayout.setVisibility(View.VISIBLE);
				progressBar.setProgress(progress);
				
				if (progress == 100) {
					frameLayout.setVisibility(View.GONE);
				}
				
				super.onProgressChanged(view, progress);
			}
		});
		webView.getSettings().setJavaScriptEnabled(true);
		webView.setVerticalScrollBarEnabled(false);
		webView.loadUrl("https://wijaksana.com");
		
		progressBar.setProgress(0);						
	}			
		
	private class HelpClient extends WebViewClient {
		@Override
		public boolean shouldOverrideUrlLoading(WebView view, String url) {
			view.loadUrl(url);
			frameLayout.setVisibility(View.VISIBLE);
			
			return true;
		}
	}
	
	@Override
	public boolean onKeyDown(int keyCode, KeyEvent event) {
		if (keyCode == KeyEvent.KEYCODE_BACK) {
			if (webView.canGoBack()) {
				webView.goBack();
				return true;
			}
		}
		
		return super.onKeyDown(keyCode, event);
	}
}

public class MainActivity extends AppCompatActivity {

private WebView webView;

private ProgressBar progressBar;

private FrameLayout frameLayout;

@SuppressLint("SetJavaScriptEnabled")

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

frameLayout = (FrameLayout) findViewById(R.id.frameLayout);

progressBar = (ProgressBar) findViewById(R.id.progressBar);

progressBar.setMax(100);

webView = (WebView) findViewById(R.id.webView);

webView.setWebViewClient(new HelpClient());

webView.setWebChromeClient(new WebChromeClient() {

@Override

public void onProgressChanged(WebView view, int progress) {

frameLayout.setVisibility(View.VISIBLE);

progressBar.setProgress(progress);

if (progress == 100) {

frameLayout.setVisibility(View.GONE);

}

super.onProgressChanged(view, progress);

}

});

webView.getSettings().setJavaScriptEnabled(true);

webView.setVerticalScrollBarEnabled(false);

webView.loadUrl("https://wijaksana.com");

progressBar.setProgress(0);

}

private class HelpClient extends WebViewClient {

@Override

public boolean shouldOverrideUrlLoading(WebView view, String url) {

view.loadUrl(url);

frameLayout.setVisibility(View.VISIBLE);

return true;

}

@Override

public boolean onKeyDown(int keyCode, KeyEvent event) {

if (keyCode == KeyEvent.KEYCODE_BACK) {

if (webView.canGoBack()) {

webView.goBack();

return true;

}

return super.onKeyDown(keyCode, event);

}

Buka android manifest, tambahkan permisi untuk akses internet.

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.wijaksana.android.webview.progressbar"
    android:versionCode="1"
