"built-in" progressBar technique for Webview on Android

How do I add a loading bar for Webview on Android?
I have the following working Webview code:
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class MainActivity extends AppCompatActivity {
private WebView mWebView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mWebView = (WebView) findViewById(R.id.activity_main_webview);
// Force links and redirects to open in the WebView instead of in a browser (commented out, we'll allow fice URLs only)
//mWebView.setWebViewClient(new WebViewClient());
// Stop local links and redirects from opening in browser instead of WebView
mWebView.setWebViewClient(new MyAppWebViewClient());
// Enable Javascript
WebSettings webSettings = mWebView.getSettings();
webSettings.setJavaScriptEnabled(true);
mWebView.loadUrl("http://google.com");
}
#Override
public void onBackPressed() {
if(mWebView.canGoBack()) {
mWebView.goBack();
} else {
super.onBackPressed();
}
}
}
I'm aiming to add a simple prograss bar/loading bar but can't seem to find how to do this.

Try this.
public class MainActivity extends AppCompatActivity {
private WebView mWebView;
ProgressBar progressBar;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mWebView = (WebView) findViewById(R.id.activity_main_webview);
progressBar = (ProgressBar) findViewById(R.id.progressBar1);
// Force links and redirects to open in the WebView instead of in a browser (commented out, we'll allow fice URLs only)
//mWebView.setWebViewClient(new WebViewClient());
// Stop local links and redirects from opening in browser instead of WebView
mWebView.setWebViewClient(new myWebClient());
// Enable Javascript
WebSettings webSettings = mWebView.getSettings();
webSettings.setJavaScriptEnabled(true);
mWebView.loadUrl("http://google.com");
}
public class myWebClient extends WebViewClient
{
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
// TODO Auto-generated method stub
super.onPageStarted(view, url, favicon);
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
// TODO Auto-generated method stub
progressBar.setVisibility(View.VISIBLE);
view.loadUrl(url);
return true;
}
#Override
public void onPageFinished(WebView view, String url) {
// TODO Auto-generated method stub
super.onPageFinished(view, url);
progressBar.setVisibility(View.GONE);
}
}
// To handle "Back" key press event for WebView to go back to previous screen.
#Override
public boolean onKeyDown(int keyCode, KeyEvent event)
{
if ((keyCode == KeyEvent.KEYCODE_BACK) && mWebView.canGoBack()) {
mWebView.goBack();
return true;
}
return super.onKeyDown(keyCode, event);
}
#Override
public void onBackPressed() {
if(mWebView.canGoBack()) {
mWebView.goBack();
} else {
super.onBackPressed();
}
}
}
Don't forget to Add this in your XML before Web View.
<ProgressBar
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_gravity="center"
android:id="#+id/progressBar1"/>

This is your code. try it!!!
Create class MyWebChromeClient.class
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 WebviewActivity.class
public class WebviewActivity extends BaseActivity implements MyWebChromeClient.ProgressListener {
private ProgressBar mProgressBar;
private WebView mWebView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.webview_layout);
mWebView = (WebView) findViewById(R.id.web_view);
mProgressBar = (ProgressBar) findViewById(R.id.progressBar);
mWebView.setWebChromeClient(new MyWebChromeClient(this));
mWebView.setWebViewClient(new WebViewClient() {
#Override
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.GONE);
}
}
}
this is webview_layout.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
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_history" />
<WebView
android:id="#+id/web_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/progressBar" />
</RelativeLayout>
create bg_progress_bar_history.xml in drawable
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="#android:id/background"
android:drawable="#android:color/transparent" />
<item android:id="#android:id/secondaryProgress">
<scale
android:drawable="#drawable/progress_bar_second"
android:scaleWidth="100%" />
</item>
<item android:id="#android:id/progress">
<scale
android:drawable="#color/color_bg_splash"
android:scaleWidth="100%" />
</item>
</layer-list>

you should implement custom WebViewClient
mWebView.getSettings().setBuiltInZoomControls(true);
mWebView.getSettings().setSupportZoom(true);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.setWebViewClient(new CustomWebViewClient());
mProgressBar.setVisibility(View.VISIBLE); // here show your progress view
mWebView.loadUrl("http://google.com");
and custom WebViewClient:
private class CustomWebViewClient extends WebViewClient
{
#Override
public void onPageFinished(WebView view, String url) {
super.onPageFinished(view, url);
runOnUiThread(new Runnable() {
#Override
public void run() {
mProgressBar.setVisibility(View.GONE);
}
}); // here hide progress view
}
}

Android webview setWebViewClient() show nothing

guys! I have problem to load html page with android-webview. I need to load the url with my webview but not with the mobile system broswer or other broswer, so I have to apply the method setWebViewClient() to my webview but not WebChromeClient(). However, there's load nothing but blank page when applied the setWebViewClient(), and works fine with the later method. I don't know where's problem, here is the code:
.xml :
<WebView android:id="#+id/webview"
android:layout_marginTop="50dp"
android:layout_width="fill_parent"
android:layout_height="fill_parent"/>
.java :
WebView webView = (WebView)findViewById(R.id.webView);
WebSettings webSettings = webView.getSettings();
webSettings.setJavaScriptEnabled(true);
if (Build.VERSION.SDK_INT >= 19) {
webSettings.setCacheMode(WebSettings.LOAD_CACHE_ELSE_NETWORK);
}
private String loadUrl = "http://www.baidu.com";
webView.loadUrl(loadUrl);
webView.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
#Override
public void onLoadResource(WebView view, String url) {
view.loadUrl(url);
super.onLoadResource(view, url);
}
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
view.loadUrl(url);
super.onPageStarted(view, url, favicon);
}
});
/*
webView.setWebChromeClient(new WebChromeClient() {
#Override
public void onProgressChanged(WebView view, int newProgress) {
Log.v(Log_Tag, String.valueOf(newProgress));
}
});
*/

Just put this code in your activity
private String loadUrl = "https://www.google.com";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
WebView mWebView = (WebView) findViewById(R.id.webView);
WebSettings mWebSettings = mWebView.getSettings();
mWebSettings.setJavaScriptEnabled(true);
WebViewClient mWebViewClient = new WebViewClient();
mWebView.setWebViewClient(mWebViewClient);
mWebView.loadUrl(loadUrl);
}
You shouldn't override methods in WebViewClient class if you don't want to change their behavior or add some functionality. And don't forget to add permission Internet to your manifest file. WebView will not work without it.

Thanks #Mike M. again. The method shouldOverrideUrlLoading() should return false if you want to loading the url with your webView but not with the mobile system default browser or other Third-Party browsers. And, if you want to deal some javascript actions of the webpage with your webView, you're suggested to apply the WebChromClient to your webView.
Here is the good example:
WebView webView = (WebView)findViewById(R.id.webView);
WebSettings webSettings = webView.getSettings();
webSettings.setJavaScriptEnabled(true);
//load the page with cache
if (Build.VERSION.SDK_INT >= 19) {
webSettings.setCacheMode(WebSettings.LOAD_CACHE_ELSE_NETWORK);
}
webView.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
//return true load with system-default-browser or other browsers, false with your webView
return false;
}
#Override
public void onLoadResource(WebView view, String url) {
super.onLoadResource(view, url);
}
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
super.onPageStarted(view, url, favicon);
}
});
webView.setWebChromeClient(new WebChromeClient() {
#Override
public void onProgressChanged(WebView view, int newProgress) {
Log.v(Log_Tag, String.valueOf(newProgress));
//put your code here if your want to show the progress with progressbar
}
});
private String loadUrl = "http://www.baidu.com";
webView.loadUrl(loadUrl);

public class MainActivity extends AppCompatActivity {
WebView webView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
webView = findViewById(R.id.webView);
webView.setWebViewClient(new WebViewClient());
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl("https://www.w3schools.com/");

WebView onPageFinished not called when MapView is visible

I have a MapView inside a fragment which creates a WebView and a loads URL.
The WebView loads fine if the MapView is hidden (android:visibility="gone"). But when it is made visible, the WebView's onPageStarted() is called but onPageFinished() is never called.
MapView:
<com.google.android.gms.maps.MapView
android:layout_width="match_parent"
android:layout_height="200dp"
android:visibility="gone"
android:id="#+id/mapView" />
WebView:
webView = new WebView(getActivity());
webView.addJavascriptInterface(this, "scraper");
WebSettings webSettings = webView.getSettings();
webSettings.setUserAgentString("Mozilla/5.0 (Windows NT 5.1; rv:31.0) Gecko/20100101 Firefox/31.0");
webSettings.setJavaScriptEnabled(true);
webSettings.setDomStorageEnabled(true);
webView.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
return true;
}
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
super.onPageStarted(view, url, favicon);
System.out.println("page start called");
}
#Override
public void onPageFinished(WebView view, String url) {
super.onPageFinished(view, url);
System.out.println("page finished called");
}
});
webView.loadUrl("http://denver.craigslist.org/apa/5436947521.html");
Few Observations:
If I leave the MapView hidden, WebView loads fine.
Only Log message after onPageStarted() - D/cr_Ime: [ImeAdapter.java:587] detach
Nothing in onReceivedError() or any other error callbacks.

I have done this way, it works fine for me.
I have used MapFragment instead of MapView.
fragment_location.xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<fragment
android:id="#+id/map"
android:name="com.google.android.gms.maps.MapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</RelativeLayout>
LocationFragment.java:
public class LocationFragment extends Fragment implements OnMapReadyCallback {
private static View view;
private GoogleMap googleMap;
private double latitude = 23.0300, longitude = 72.5800;
private WebView webView;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState)
{
if (view != null) {
ViewGroup parent = (ViewGroup) view.getParent();
if (parent != null)
parent.removeView(view);
}
try
{
view = inflater.inflate(R.layout.fragment_location,null);
MapFragment mapFragment = (MapFragment) getActivity().getFragmentManager()
.findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
}catch (InflateException e) {
/* map is already there, just return view as it is */
}
return view;
}
#Override
public void onMapReady(GoogleMap googleMap) {
LatLng mLatLong = new LatLng(latitude, longitude);
googleMap.setMyLocationEnabled(true);
googleMap.moveCamera(CameraUpdateFactory.newLatLngZoom(mLatLong, 13));
googleMap.addMarker(new MarkerOptions()
.title("MyTitle")
.snippet("MySnippet")
.position(mLatLong));
if(webView!=null){
webView.requestFocus();
}
}
#Override
public void onResume() {
super.onResume();
webView = new WebView(getActivity());
webView.addJavascriptInterface(this, "scraper");
WebSettings webSettings = webView.getSettings();
webSettings.setUserAgentString("Mozilla/5.0 (Windows NT 5.1; rv:31.0) Gecko/20100101 Firefox/31.0");
webSettings.setJavaScriptEnabled(true);
webSettings.setDomStorageEnabled(true);
webView.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
return true;
}
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
super.onPageStarted(view, url, favicon);
Log.i("WebView", "page start called");
}
#Override
public void onPageFinished(WebView view, String url) {
super.onPageFinished(view, url);
Log.i("WebView", "page finished called");
}
});
webView.loadUrl("http://stackoverflow.com/");
}
}
In my case onPageStarted & onPageFinished both are getting triggered.
Screenshot:
Edit 1: Actually MapView always take focus while initialization so once MapView initialization process done request focus to WebView.
Hope this will help you.

Android Webview don't support map that's why it's not show.

WebView cannot load webpage inside

I wanna load webpage inside fragment, but there is some problem.
1.without overriding shouldOverrideUrlLoading method, the website is open with default browser Chrome.
2.when overriding shouldOverrideUrlLoading, nothing happens. just new blank activity is created.
This is my onCreateView method inside Fragment class
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View resultView = inflater.inflate(R.layout.container, container, false);
if (getArguments() != null) {
String url = getArguments().getString(KEY_URL);
WebView productDetailView = (WebView)resultView.findViewById(R.id.webView);
productDetailView.setWebViewClient(new WebViewClient() {
public boolean shouldOverrideUrlLoading(WebView view, String url) {
return super.shouldOverrideUrlLoading(view, url);
}
});
productDetailView.loadUrl(url);
}
return resultView;
}
targetSdkVersion is 19 and added INTERNET permission and XML file of Fragment is like below.
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.example.ProductDetailFragment">
<WebView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/webView"
android:layout_gravity="center" />
</FrameLayout>
what's the problem?

Try this code
webView.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
});
webView.loadUrl(url);
and start your activity with FLAG_ACTIVITY_NEW_TASK

webView = (WebView) findViewById(R.id.webView1);
webView.getSettings().setJavaScriptEnabled(true);
Intent intent = getIntent();
webView.setSaveEnabled(false);
String receivedName = (String) intent.getSerializableExtra("USERNAME");
Log.d("receivedName ----- ", receivedName);
webView.loadUrl("https://docs.google.com/gview?embedded=true&url=" +
receivedName);
webView.setDownloadListener(new DownloadListener() {
public void onDownloadStart(String url, String userAgent,
String contentDisposition, String mimetype,
long contentLength) {
Webview.this.finish();
}
});
Try this code...

Try this.
final ProgressDialog pd = ProgressDialog.show(ActivityA.this, "", "Loading...", true);
wv = (WebView) findViewById(R.id.webview);
wv.getSettings().setJavaScriptEnabled(true);
wv.loadUrl("<url");
wv.setWebViewClient(new WebViewClient() {
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon)
{
pd.show();
}
#Override
public void onPageFinished(WebView view, String url) {
pd.dismiss();
}
});

Have you tried adding this <uses-permission android:name="android.permission.INTERNET" />
into Manifest file ?

Add a Progress Bar in WebView

I am trying to add a progress/loading bar to my application that uses WebView. I am confused on how to implement a progress bar that appears every time a link is clicked.
Current code:
public class CULearnBrowser extends Activity {
WebView webview;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
webview = (WebView) findViewById(R.id.webview);
webview.setWebViewClient(new HelloWebViewClient());
webview.getSettings().setJavaScriptEnabled(true);
webview.loadUrl("https://culearn.colorado.edu/webct/entryPageIns.dowebct");
}
private class HelloWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
}
public boolean onKeyDown(int keyCode, KeyEvent event) {
if ((keyCode == KeyEvent.KEYCODE_BACK) && webview.canGoBack()) {
webview.goBack();
return true;
}
return super.onKeyDown(keyCode, event);
}
}
Activity 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 xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/webview"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/hello" />
</LinearLayout>

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");

pass your url in this method
private void startWebView(String url) {
WebSettings settings = webView.getSettings();
settings.setJavaScriptEnabled(true);
webView.setScrollBarStyle(View.SCROLLBARS_OUTSIDE_OVERLAY);
webView.getSettings().setBuiltInZoomControls(true);
webView.getSettings().setUseWideViewPort(true);
webView.getSettings().setLoadWithOverviewMode(true);
progressDialog = new ProgressDialog(ContestActivity.this);
progressDialog.setMessage("Loading...");
progressDialog.show();
webView.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
#Override
public void onPageFinished(WebView view, String url) {
if (progressDialog.isShowing()) {
progressDialog.dismiss();
}
}
#Override
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
Toast.makeText(ContestActivity.this, "Error:" + description, Toast.LENGTH_SHORT).show();
}
});
webView.loadUrl(url);
}

in oncreate method where you have set your Webview.
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.web_view);
web_view = (WebView) findViewById(R.id.web_view);
pd = new ProgressDialog(SiteOpenInWebView.this);
pd.setMessage("Please wait Loading...");
pd.show();
web_view.setWebViewClient(new MyWebViewClient());
web_view.loadUrl("ur site name");
}
WebViewClient
private class MyWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
if (!pd.isShowing()) {
pd.show();
}
return true;
}
#Override
public void onPageFinished(WebView view, String url) {
System.out.println("on finish");
if (pd.isShowing()) {
pd.dismiss();
}
}
}

Here is the code that I am using:
Inside WebViewClient:
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
super.onPageStarted(view, url, favicon);
findViewById(R.id.progress1).setVisibility(View.VISIBLE);
}
#Override
public void onPageFinished(WebView view, String url) {
findViewById(R.id.progress1).setVisibility(View.GONE);
}
Here is the XML :
<ProgressBar
android:id="#+id/progress1"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
Hope this helps..

The best approch which worked for me is
webView.setWebViewClient(new WebViewClient() {
#Override public void onPageStarted(WebView view, String url, Bitmap favicon) {
super.onPageStarted(view, url, favicon);
mProgressBar.setVisibility(ProgressBar.VISIBLE);
webView.setVisibility(View.INVISIBLE);
}
#Override public void onPageCommitVisible(WebView view, String url) {
super.onPageCommitVisible(view, url);
mProgressBar.setVisibility(ProgressBar.GONE);
webView.setVisibility(View.VISIBLE);
isWebViewLoadingFirstPage=false;
}
}

Put a progress bar and the webview inside a relativelayout and set the properties for the progress bar as follows,
Make its visibility as GONE.
CENTRE it in the Relativelayout.
and then in onPageStarted() of the webclient make the progress bar visible so that it shows the progressbar when you have clicked on a link. In onPageFinished() make the progress bar visiblility as GONE so that it disappears when the page has finished loading... This will work fine for your scenario. Hope this helps...

I try dismis progress on method onPageFinished(), but not good too much, it has time delay to render webview.
try with onPageCommitVisible() better:
val progressBar = ProgressDialog(context)
progressBar.setCancelable(false)
progressBar.show()
val url = "your url here"
web_container.settings.javaScriptEnabled = true
web_container.loadUrl(url)
web_container.webViewClient = object : WebViewClient() {
override fun shouldOverrideUrlLoading(view: WebView, url: String): Boolean {
view.loadUrl(url)
progressBar.show()
return true
}
override fun onPageFinished(view: WebView?, url: String?) {
super.onPageFinished(view, url)
}
override fun onPageCommitVisible(view: WebView?, url: String?) {
super.onPageCommitVisible(view, url)
progressBar.dismiss()
}
}
web_container.setOnKeyListener(View.OnKeyListener { _, keyCode, event ->
if (keyCode == KEYCODE_BACK && event.action == MotionEvent.ACTION_UP
&& web_container.canGoBack()) {
web_container.goBack()
return#OnKeyListener true
}
return#OnKeyListener false
})

You can try this code into your activity
private void startWebView(WebView webView,String url) {
webView.setWebViewClient(new WebViewClient() {
ProgressDialog progressDialog;
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return false;
}
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
super.onPageStarted(view, url, favicon);
}
public void onLoadResource (WebView view, String url) {
if (progressDialog == null) {
progressDialog = new ProgressDialog(SponceredDetailsActivity.this);
progressDialog.setMessage("Loading...");
progressDialog.show();
}
}
public void onPageFinished(WebView view, String url) {
try{
if (progressDialog.isShowing()) {
progressDialog.dismiss();
progressDialog = null;
}
}catch(Exception exception){
exception.printStackTrace();
}
}
});
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl(url);
}
Call this method using this way:
startWebView(web_view,"Your Url");
Sometimes if URL is dead it will redirected and it will come to onLoadResource() before onPageFinished method. For this reason progress bar will not dismis. To solve this issue see my this Answer.
Thanks :)
