Here's my code:
public class MainActivity extends Activity {
#SuppressLint("SetJavaScriptEnabled") #Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
WebView mywebview = (WebView) findViewById(R.id.webview);
mywebview.loadUrl("http://www.shufflemylife.com/shuffle");
WebSettings webSettings = mywebview.getSettings();
webSettings.setJavaScriptEnabled(true);
mywebview.setWebViewClient(new WebViewClient());
}
class MyWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if(url.contains("/shuffle")){
Intent i = new Intent(Intent.ACTION_VIEW);
i.setData(Uri.parse(url));
startActivity(i);
}
return true;
}
}
}
Basically, I want any url containing '/shuffle' to load inside WebView, and anything else to be opened in the external browser. Is it doable? How close am I do accomplishing this?
Thanks for any help!
To clarify, this is how you should write your shouldOverrideUrlLoading method:
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (url.contains("/shuffle")) {
mWebView.loadUrl(url);
return false;
} else {
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse(url));
startActivity(intent);
return true;
}
}
Is it doable?
Yes.
How close am I do accomplishing this?
Close, but backwards. The default behavior of a WebView is to display links in the external browser. Hence, if url.contains("/shuffle"), you want to call loadUrl() on your WebView to keep the link internal, and return true in that case. If this is a URL you want handled normally, return false.

I want to do an app that is mainly base on webview. MainActivity is to load www.example.com/products.php.
www.example.com/products.php - display all products*
www.example.com/products.php?id=123 - display individual product base on product ID
www.example.com/cart.php - when clickcing on "Add to cart" on product.php?id=123, it will not open a new Activity but remain in the same activity.
MainActivity.java
private WebView wv;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
wv = (WebView) findViewById(R.id.webView);
WebSettings wss = wv.getSettings();
wss.setJavaScriptEnabled(true);
wv.loadUrl("http://www.example.com/product.php");
wv.setWebViewClient(new WebViewClient());
}
private class MyWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (Uri.parse(url).getHost().equals("www.example.com/cart.php")) {
// This is my web site, so do not override; let my WebView load the page
return false;
}else{
// Otherwise, the link is not for a page on my site, so launch another Activity that handles URLs
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
startActivity(intent);
return true;
}
}
}
#Override
public void onBackPressed() {
if(wv.canGoBack()){
wv.goBack();
}else{
super.onBackPressed();
}
}
And also for "shouldOverrideUrlLoading " , it shows depreciated... so what's the new name for this?
I have a webview app and facing a problem that
when I click on Hyperlink then it opens in default browser.
But I want to open that link in same webview.
How to open it in same webview.
Here is my code.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
WebView myWebView = (WebView) findViewById(R.id.myWebView);
myWebView.loadUrl("file:///android_asset/abc/index.html");
myWebView.setWebViewClient(new MyWebViewClient());
WebSettings webSettings = myWebView.getSettings();
webSettings.setJavaScriptEnabled(true);
}
private class MyWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (Uri.parse(url).getHost().equals("file:///android_asset/abc/index.html")) {
return false;
}
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
startActivity(intent);
return true;
}
}
Do it like,
myWebView.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return false;
}
});
Return false in all cases.
ok.. you have added a WebViewClient also..
then try it in this way...
myWebView.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return false;
}
});
this should work for you..
I have a webview and I am calling data in that wv from a webservice, and in that whole description in a webview, there is a link in the last. so, my problem is that i want to open a new activity onclick of that link only neither onclick of webview nor ontouch of webview
You need to provide an implementation for shouldOverrideUrlLoading. You'll have to setup a WebViewClient for your webview and inside of this method, you'll need to have some logic that recognized that link and then open the new Activity. Something like:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
WebView wv = (WebView) findViewById(R.id.myWebView);
wv.setWebViewClient(new WebViewClient(){
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if(isURLMatching(url)) {
openNextActivity();
return true;
}
return super.shouldOverrideUrlLoading(view, url);
}
});
}
protected boolean isURLMatching(String url) {
// some logic to match the URL would be safe to have here
return true;
}
protected void openNextActivity() {
Intent intent = new Intent(this, MyNextActivity.class);
startActivity(intent);
}
I use WebChromeClient for opening a link to news.html on my server, it opens safari and shows the content, ok.
But...
When I implent WebViewClient shouldOverrideUrlLoading to intercept the call when it's link to a .pdf file (use another class for it) the WebChromeClient link to news.html stays in webview and does not open safari anymore...
I am doing something wrong, but what?
Code snippet: (links are long so I shortened it)
myWebView = (WebView)findViewById(R.id.webView);
myWebView.getSettings().setJavaScriptEnabled(true);
//only to catch url override
myWebView.setWebViewClient(new WebViewClient(){
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if(url.startsWith("http://www.domain.nl/pdf")){
Intent i = new Intent();
i.putExtra("url", url);
i.setClassName("nl.domain.domain", "nl.domain.domain.PdfActivity");
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(i);
return true ;
}
else {
return false ;
}
}
});
myWebView.setWebChromeClient(new WebChromeClient());
//loading
myWebView.loadUrl("http://www.domain.nl/news.html");
return false; means that the url wasn't handled and it should be opened in the WebView. If you want to open the url in an external browser you need to explicitly do it.
myWebView.setWebViewClient(new WebViewClient(){
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if(url.startsWith("http://www.domain.nl/pdf")){
Intent i = new Intent();
i.putExtra("url", url);
i.setClassName("nl.domain.domain", "nl.domain.domain.PdfActivity");
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(i);
return true ;
}
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(url));
return true;
}
});
To open the PDF file url :
add the "http://docs.google.com/viewerembedded=true&url=" string at starting of PDF file url string...
try this it work
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
WebView webView;
webView = new WebView(this);
WebSettings settings = webView.getSettings();
settings.setJavaScriptEnabled(true);
settings.setPluginsEnabled(true);
webView.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY);
if (webUrl.equals(XmlFileUrl.MemberDownloadAppForm)) {
webUrl = "http://docs.google.com/viewerembedded=true&url=" + webUrl;
}
webView.setWebViewClient(new WebViewClient() {
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
});
webView.loadUrl(url);
setContentView(webView);
}
An example that helped me to do something similar Here
For geolocation add:
myWebView.getSettings().setGeolocationEnabled(true);
and :
private class MyWebChromeClient extends WebChromeClient {
.........
#Override
public void onGeolocationPermissionsShowPrompt(String origin, GeolocationPermissions.Callback callback)
{
// callback.invoke(String origin, boolean allow, boolean remember);
callback.invoke(origin, true, false);
}
}
I created an Activity that has a title and a web view in a LinearLayout. In the onResume() method it calls webView.loadUrl(url). The problem is that the activity first shows the title with the rest of the screen blank, then the device browser is launched with the page for the URL. What I want to see is the page being shown in the WebView below the title. What could be the problem?
Edit:
Ok, did some further search and found this one:
Clicking URLs opens default browser
It points to the WebView tutorial here.
Just implement the web client and set it.
Answering my question based on the suggestions from Maudicus and Hit.
Check the WebView tutorial here.
Just implement the web client and set it before loadUrl. The simplest way is:
myWebView.setWebViewClient(new WebViewClient());
For more advanced processing for the web content, consider the ChromeClient.
Use this:
lWebView.setWebViewClient(new WebViewClient());
use like this:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_dedline);
WebView myWebView = (WebView) findViewById(R.id.webView1);
myWebView.setWebViewClient(new WebViewClient());
myWebView.loadUrl("https://google.com");
}
Make your Activity like this.
public class MainActivity extends Activity {
WebView browser;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// find the WebView by name in the main.xml of step 2
browser=(WebView)findViewById(R.id.wvwMain);
// Enable javascript
browser.getSettings().setJavaScriptEnabled(true);
// Set WebView client
browser.setWebChromeClient(new WebChromeClient());
browser.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
});
// Load the webpage
browser.loadUrl("http://google.com/");
}
}
I was facing the same problem and I found the solution
Android's official Documentation about WebView
Here is my onCreateView() method and here i used two methods to open the urls
Method 1 is opening url in Browser and
Method 2 is opening url in your desired WebView.
And I am using Method 2 for my Application and this is my code:
public class MainActivity extends Activity {
private WebView myWebView;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_webpage_detail, container, false);
// Show the dummy content as text in a TextView.
if (mItem != null) {
/* Method : 1
This following line is working fine BUT when we click the menu item then it opens the URL in BROWSER not in WebView */
//((WebView) rootView.findViewById(R.id.detail_area)).loadUrl(mItem.url);
// Method : 2
myWebView = (WebView) rootView.findViewById(R.id.detail_area); // get your WebView form your xml file
myWebView.setWebViewClient(new WebViewClient()); // set the WebViewClient
myWebView.loadUrl(mItem.url); // Load your desired url
}
return rootView;
} }
Try this code...
private void startWebView(String url) {
//Create new webview Client to show progress dialog
//When opening a url or click on link
webView.setWebViewClient(new WebViewClient() {
ProgressDialog progressDialog;
//If you will not use this method url links are opeen in new brower not in webview
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
//Show loader on url load
public void onLoadResource (final WebView view, String url) {
if (progressDialog == null) {
// in standard case YourActivity.this
progressDialog = new ProgressDialog(view.getContext());
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();
}
}
});
// Javascript inabled on webview
webView.getSettings().setJavaScriptEnabled(true);
// Other webview options
/*
webView.getSettings().setLoadWithOverviewMode(true);
webView.getSettings().setUseWideViewPort(true);
webView.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY);
webView.setScrollbarFadingEnabled(false);
webView.getSettings().setBuiltInZoomControls(true);
*/
/*
String summary = "<html><body>You scored <b>192</b> points.</body></html>";
webview.loadData(summary, "text/html", null);
*/
//Load url in webview
webView.loadUrl(url);
}
If you see an empty page, enable JavaScript.
webView.setWebViewClient(new WebViewClient());
WebSettings webSettings = webView.getSettings();
webSettings.setJavaScriptEnabled(true);
webSettings.setDomStorageEnabled(true);
webView.loadUrl(url);
Simply Answer you can use like this
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
WebView webView = new WebView(this);
setContentView(webView);
webView.setWebViewClient(new WebViewClient());
webView.loadUrl("http://www.google.com");
}
}
If you're using webChromeClient I'll suggest you to use webChromeClient and webViewClient together. because webChromeClient does not provides shouldOverrideUrlLoading. It is okay to use both.
webview.webViewClient = WebViewClient()
webview.webChromeClient = Callback()
private inner class Callback : WebChromeClient() {
override fun onProgressChanged(view: WebView?, newProgress: Int) {
super.onProgressChanged(view, newProgress)
if (newProgress == 0) {
progressBar.visibility = View.VISIBLE
} else if (newProgress == 100) {
progressBar.visibility = View.GONE
}
}
}
I just found out that it depends on the formatting of the URL:
https://example.com/example gets opened in the browser
https://example.com/example/ (with / at the end) gets opened in the webView
My code just uses
webview.loadUrl(url)
no need to set
webView.setWebViewClient(new WebViewClient())
at least in my case.
Maybe that's useful for some of you.
My problem ended up being that I needed to do a clearHistory before I could switch between sites without opening an external browser.
#Override
public void onPageFinished(WebView view, String url) {
webView_.clearHistory();
super.onPageFinished(webView_, url);
}
