I'm trying to show a progressbar on top top the app like google chrome for android shows loading bar while loading a website.
I want to show this progress bar when user clicks on any internal links of the webview app...just like google chrome shows.
Here is what I've tried, this code not working, app stops working even it doesn't start.
public class MainActivity extends AppCompatActivity {
private WebView mWebView;
private ProgressBar progressBar;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getWindow().setBackgroundDrawable(null);
progressBar = (ProgressBar) findViewById(R.id.progressBar);
progressBar.setMax(100);
setContentView(R.layout.activity_main);
mWebView = (WebView) findViewById(R.id.main_webview);
mWebView.setWebViewClient(new WebViewClient() {
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
super.onPageStarted(view, url, favicon);
progressBar.setVisibility(View.VISIBLE);
progressBar.setProgress(0);
}
#Override
public void onPageFinished(WebView view, String url) {
super.onPageFinished(view, url);
progressBar.setVisibility(View.GONE);
progressBar.setProgress(100);
if (mWebView.getProgress() == 100) {
// show webview
mWebView.setVisibility(View.VISIBLE);
// hide splash
findViewById(R.id.splash_screen).setVisibility(View.GONE);
}
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (Uri.parse(url).getHost().contains("www.example.com")) {
return false;
}
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
view.getContext().startActivity(intent);
return true;
}
public void onReceivedError(WebView view, int errorCode,
String description, String failingUrl) {
view.loadUrl("file:///android_asset/offline.html");
}
});
mWebView.loadUrl("http://www.example.com/?m=1");
}
}
main activity:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"

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);
}
}
}

I have used the following in my projects:

public class DetectConnection {
public static boolean checkInternetConnection(Context context) {
ConnectivityManager con_manager = (ConnectivityManager)
context.getSystemService(Context.CONNECTIVITY_SERVICE);
return (con_manager.getActiveNetworkInfo() != null
&& con_manager.getActiveNetworkInfo().isAvailable()
&& con_manager.getActiveNetworkInfo().isConnected());
}
}
import android.content.Context;
import android.net.ConnectivityManager;
public class DetectConnection {
public static boolean checkInternetConnection(Context context) {
ConnectivityManager con_manager = (ConnectivityManager)
context.getSystemService(Context.CONNECTIVITY_SERVICE);
return (con_manager.getActiveNetworkInfo() != null
&& con_manager.getActiveNetworkInfo().isAvailable()
&& con_manager.getActiveNetworkInfo().isConnected());
}
}
if (!DetectConnection.checkInternetConnection(this)) {
Toast.makeText(getApplicationContext(), "No Internet!", Toast.LENGTH_SHORT).show();
} else {
wv = (WebView) findViewById(R.id.donate_webView1);
c = new CustomWebViewClient();
wv.setWebViewClient(c);
wv.clearCache(true);
wv.clearHistory();
wv.getSettings().setJavaScriptEnabled(true);
wv.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
wv.getSettings().setBuiltInZoomControls(true);
wv.loadUrl("http://www.google.com");
}
// Function to load all URLs in same webview
private class CustomWebViewClient extends WebViewClient {
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (!DetectConnection.checkInternetConnection(this)) {
Toast.makeText(getApplicationContext(), "No Internet!", Toast.LENGTH_SHORT).show();
} else {
view.loadUrl(url);
}
return true;
}
}
Update the Manifest:
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
I used this code to make custom No internet dialog but when i successfully build then the problem is half screen show my custom image but half show the no connection errorenter image description here

Plz help me i didnt understand the problem
try this---->
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.hdyt);
mWebView = (WebView) findViewById(R.id.activity_main_webview);
WebSettings webSettings = mWebView.getSettings();
//Button No Internet//
btnNoInternetConnection = (Button) findViewById(R.id.btnNoConnection);
relativeLayout = (RelativeLayout) findViewById(R.id.relativeLayout); //No Internet//
webSettings.setJavaScriptEnabled(true);
progressBarWeb = (ProgressBar) findViewById(R.id.ProgressBar);
checkConnection();
// mWebView.loadUrl("https://www.foodmartshop.com");
//Swipe//
swipeRefreshLayout = (SwipeRefreshLayout) findViewById(R.id.swipeRefreshLayout);
swipeRefreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
#Override
public void onRefresh() {
checkConnection();
mWebView.reload();
}
}); //Swipe//
// mWebView.loadUrl("https://www.foodmartshop.com");
mWebView.setWebViewClient(new MyAppWebViewClient() {
//Hide The Loading Page
#Override
public void onPageFinished(WebView view, String url) {
findViewById(R.id.splashloading01).setVisibility(View.GONE);
findViewById(R.id.activity_main_webview).setVisibility(View.VISIBLE);
swipeRefreshLayout.setRefreshing(false);
}
});

progressBarWeb.setProgress(newProgress);
if (newProgress == 100) {
progressBarWeb.setVisibility(View.GONE);
}
else
{
checkConnection();
}
super.onProgressChanged(view, newProgress);
}
});
}
#Override
public void onBackPressed() {
if (mWebView.canGoBack()) {
mWebView.goBack();
} else {
super.onBackPressed();
}
}
private class MyAppWebViewClient extends WebViewClient {
}
public void checkConnection() {
ConnectivityManager connectivityManager = (ConnectivityManager)
this.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo wifi = connectivityManager.getNetworkInfo(ConnectivityManager.TYPE_WIFI);

if (!wifi.isConnected()) {
progressBarWeb.setVisibility(View.GONE);

mWebView.setVisibility(View.VISIBLE);
relativeLayout.setVisibility(View.GONE);
}
}
}
later you must be noticing progressbar loads continuously even if internet is not there then you must use this-->
just an example -->
webView.setWebViewClient(new WebViewClient() {
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
super.onPageStarted(view, url, favicon);
progressBar.setVisibility(View.VISIBLE);
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
#Override
public void onPageFinished(WebView view, String url) {
progressDialog.hide();
progressBar.setVisibility(View.GONE);
}
});
This is my 1st time using Java and Android, I’m trying to launch a simple application with WebView script.
Everything was okay but I am facing issue when I’m trying to add loading bar for my web view page. The problem:
error: reached end of file while parsing
I’m using this code for Mainactivity
package com.example.last;
import android.graphics.Bitmap;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.webkit.WebChromeClient;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.ProgressBar;
public class MainActivity extends AppCompatActivity {
private WebView webView;
private ProgressBar mProgressbar;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
webView =(WebView) findViewById(R.id.WebView);
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
mProgressbar=findViewById(R.id.progressBar);
mProgressbar.setMax(100);
webView.setWebViewClient(new WebViewClient());
webView.loadUrl("https://beko963.000webhostapp.com");
webView.setWebViewClient(new WebChromeClient() {
#Override
public void onProgressChanged(WebView view, int newProgress) {
super.onProgressChanged(view, newProgress);
mProgressbar.setProgress(newProgress);
}
#Override
public void onReceivedTitle(WebView view, String title) {
super.onReceivedTitle(view, title);
}
#Override
public void onReceivedIcon(WebView view, Bitmap icon) {
super.onReceivedIcon(view, icon);
}
}}
#Override
public void onBackPressed () {
if (webView.canGoBack()) {
webView.goBack();
} else
super.onBackPressed();
}}
And using this for main XML:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="16dp"
tools:context=".MainActivity">
<ProgressBar
android:id="#+id/progressBar"
style="#style/Base.Widget.AppCompat.ProgressBar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentStart="true"
android:layout_centerVertical="true" />
<WebView
android:id="#+id/WebView"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</RelativeLayout>
I just want to make a simple application with loading icon, could you please help my and fix my code?
As John and Others Says
webView.setWebViewClient(new WebChromeClient() {}} where is the closing )
//replace last } with );
webView.setWebViewClient(new WebChromeClient() {
#Override
public void onProgressChanged(WebView view, int newProgress) {
super.onProgressChanged(view, newProgress);
mProgressbar.setProgress(newProgress);
}
#Override
public void onReceivedTitle(WebView view, String title) {
super.onReceivedTitle(view, title);
}
#Override
public void onReceivedIcon(WebView view, Bitmap icon) {
super.onReceivedIcon(view, icon);
}
});
Correct your code
webView.setWebChromeClient(new WebChromeClient() {
#Override
public void onProgressChanged(WebView view, int newProgress) {
super.onProgressChanged(view, newProgress);
mProgressbar.setProgress(newProgress);
}
#Override
public void onReceivedTitle(WebView view, String title) {
super.onReceivedTitle(view, title);
}
#Override
public void onReceivedIcon(WebView view, Bitmap icon) {
super.onReceivedIcon(view, icon);
}
})
I'm using below code to populate my Main activity with Webview, but as it takes a certain time to load the page and it appears white blank. So I will like to show splash screen for my Webview before page load finishes. I'm not using any webview from Layout activity.
package com.faraksoch.sagar.facebook;
import android.app.Activity;
import android.os.Bundle;
import android.view.Window;
import android.view.WindowManager;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.Toast;
public class MainActivity extends Activity {
private WebView mWebview = null;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
mWebview = new WebView(this);
mWebview.getSettings().setJavaScriptEnabled(true); // enable javascript
final Activity activity = this;
mWebview.setWebViewClient(new WebViewClient() {
public void onPageFinished(WebView view, int errorCode, String description, String failingUrl) {
Toast.makeText(activity, description, Toast.LENGTH_SHORT).show();
}
});
mWebview.loadUrl("http://www.google.com//");
setContentView(mWebview);
}
}
I know that this code should work but I when I combine them..it won't work
WebView wv = (WebView) findViewById(R.id.webView1);
wv.getSettings().setJavaScriptEnabled(true);
wv.setWebViewClient(new WebViewClient() {
...
#Override
public void onPageFinished(WebView view, String url) {
//hide loading image
findViewById(R.id.imageLoading1).setVisibility(View.GONE);
//show webview
findViewById(R.id.webView1).setVisibility(View.VISIBLE);
}
});
wv.loadUrl("http://yoururlhere.com");
Any help will be appreciated. Thanks in advance.
Make sure webview is visibility is not GONE before it is loading.
Please refer below code.
public class WebViewActivity extends AppCompatActivity {
private WebView mWebView;
private ImageView mSplashView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_web_view);
mWebView = (WebView) findViewById(R.id.webview);
mSplashView = (ImageView) findViewById(R.id.splash_view);
mWebView.getSettings().setJavaScriptEnabled(true); // enable javascript
mWebView.setWebViewClient(new WebViewClient() {
#Override
public void onPageFinished(WebView view, String url) {
super.onPageFinished(view, url);
mSplashView.setVisibility(View.GONE);
mWebView.setVisibility(View.VISIBLE);
Toast.makeText(getBaseContext(), "Page Loaded.", Toast.LENGTH_SHORT).show();
}
});
mWebView.loadUrl("http://yoururlhere.com");
mWebView.setVisibility(View.GONE);
mSplashView.setVisibility(View.VISIBLE);
}
}

What I wanted.
I'm currently having a problem setting the background for my app. What I wanted is a page with selections of wallpaper/background for the app user to choose. Once they chose the background the wanted by clicking the Image view, the whole app should use the image as their background.That's all.
What I've done.
I've created an activity that has 2 ImageView as the choices of wallpaper available and assigns the image view to set the background image when the user click on them. The problem now is I don't know how to save the setting and apply it to all other activity in my project.

MainActivity:
public class MainActivity extends AppCompatActivity {
private static final String PREF_NAME = "nextage_quiz";
private static final int PRIVATE_MODE = 0;
SharedPreferences getPrefs;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
getPrefs = this.getSharedPreferences(PREF_NAME, PRIVATE_MODE);
ImageView background= (ImageView) findViewById(R.id.background);
if(getPrefs.getInt("id",0) != 0)
background.setBackgroundResource(getPrefs.getInt("id",0));
}
Upadate: Use these variables
private static final String PREF_NAME = "nextage_quiz";
private static final int PRIVATE_MODE = 0;
SharedPreferences getPrefs;
You should do that using Preferences.
