when I create webview application to view any website on same webview not browser it works fine but when I click on any link in that website it opens in browser ? how to load all internal links/pages/sections when user click on them at same webview ?
Java version:
You only need to set a WebViewClient for your WebView and then all links will be opened it the same WebView:
webView.setWebViewClient(new WebViewClient());
private class myCustomWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
//here load the url in your webview
webview.loadUrl(url);
return true;
}
And this for set in your webview
webView.setWebViewClient(new myCustomWebViewClient());
Kotlin version.
webView.webViewClient = WebViewClient()
You should add a webViewClient of your own.
WebView myWebView = (WebView) findViewById(R.id.webview);
myWebView.setWebViewClient(new MyWebViewClient());
in the webViewClient you can override the shouldOverrideUrlLoading() method to be like:
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (Uri.parse(url).getHost().equals("www.example.com")) {
// This is my web site, so do not override; let my WebView load the page
return false;
}
// 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;
}
I hope you find it helpful.

When I create android webview then after URL shown in the AVD. When click on any button then then it open in browser but I don't want that type of problem.
I want simple type of app ex- "ashley madison". Please help me.
...
WebView webview = (WebView) findViewById(R.id.webView);
webview.setWebChromeClient(new WebChromeClient());
webview.loadUrl(URL);
...
}
public class MyWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
return super.shouldOverrideUrlLoading(view, url);
}
}
I'm using WebView in android; I want to show ZoomControls not for all pages but only for my specific webpage. What should I do? Please Help!
Assuming that it's an activity and you are receiving the url from the intent
String url = getIntent().getStringExtra("url");
WebView webview = (WebView) findViewById(R.id.webview_id_here)
webView.getSettings().setBuiltInZoomControls(url.equals("your_url_here"));
If you want this to happen every time a url changes, use a custom webview client.
webView.setWebViewClient(new CustomWebViewClient());
wherever the webView is initialized. CustomWebViewClient :
private class CustomWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
view.getSettings().setBuiltInZoomControls(url.equals("your_url_here"));
return false;
}
}
I have a webview in my android app, but when someone navigates around the site, it opens in a new window, i want it to stay inside the webview.. is there a way to do this easily? Here is the code in my activity:
super.onCreate(savedInstanceState);
setContentView(R.layout.shop);
WebView webview;
webview = (WebView) findViewById(R.id.webview);
webview.getSettings().setJavaScriptEnabled(true);
webview.loadUrl("http://www.google.co.uk");
You'll have to create a WebViewClient:
public class myWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
}
And then set it to your WebView like this:
webview.setWebViewClient(new myWebViewClient());
Or you can just do that, without creating a new class:
myWebView.setWebViewClient(new WebViewClient());
It works for me.
webview.setWebViewClient(new WebViewClient());
If you want to customize then you should override shouldOverrideUrlLoading (WebView view, String url). but it's deprecated in API 24. You can use public boolean shouldOverrideUrlLoading (WebView view,WebResourceRequest request). actually both of them needs to return false.
Android WebView Example
I have a android code like this:
WebView myWebView = (WebView) findViewById(R.id.webView1);
WebSettings webSettings = myWebView.getSettings();
webSettings.setJavaScriptEnabled(true);
myWebView.loadUrl("http://test.com");
the problem is, when I start the app, it is opend in a new browser intend and not in my webView of the app.
how to avoid this?
Add a WebViewClient. This will prevent the default browser to open the URL (or get a selection dialog when there is no default)
myWebView.setWebViewClient(new WebViewClient());
More information can be found on Android website: http://developer.android.com/guide/webapps/webview.html
With the WebViewClient you can do more things, like preventing to load an URL, or change the URL.
private class MyWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (Uri.parse(url).getHost().equals("www.example.com")) {
// This is my web site, so do not override; let my WebView load the page
return false;
}
// 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;
}
}
I have searched and read a lot of posts but can not figure out how to do it in my code.
I want to use geolocation in my app and need to view in webChromeClient in stead of webViewClient which I use for the html files now and the links does stay in the same view.
When I change this to webChromeClient, the html links, like <a href="http://url/file.php?q=123", are suddenly opening in the browser!
How can I prevent this?
myWebView = new WebView(this);
myWebView.getSettings().setJavaScriptEnabled(true);
myWebView.getSettings().setLoadWithOverviewMode(true);
myWebView.getSettings().setUseWideViewPort(true);
myWebView.getSettings().setGeolocationEnabled(true);
myWebView.setWebChromeClient(new WebChromeClient() {
public void onGeolocationPermissionsShowPrompt(String origin, android.webkit.GeolocationPermissions.Callback callback) {
callback.invoke(origin, true, false); }
});
myWebView.loadUrl("file:///android_asset/HTML/index.html");
setContentView(myWebView);
WebChromeClient doesn't contain the shouldOverrideUrlLoading method, the WebViewClient does. Remember the "WebView" can and does use both WebViewClient and WebChromeClient at the same time if specified. The WebViewClient adds methods not available to you with no client assigned (keeping navigation in the webview). The same with the WebChromeClient has specific methods it can use (get page title on load for example).
So you can build your code like this:
WebView web = (WebView)findViewById(R.id.web);
WebSettings webSettings = web.getSettings();
webSettings.setJavaScriptEnabled(true);
webSettings.setGeolocationEnabled(true);
webSettings.setSupportMultipleWindows(true); // This forces ChromeClient enabled.
web.setWebChromeClient(new WebChromeClient(){
#Override
public void onReceivedTitle(WebView view, String title) {
getWindow().setTitle(title); //Set Activity tile to page title.
}
});
web.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return false;
}
});
I was able to get around this by setting a dummy WebViewClient in addition to the WebChromeClient. Not sure why, but when I take out this line the web page starts opening in the browser again.
mBrowser.setWebViewClient(new WebViewClient());
To open links in the browser you can use an intent in the shouldOverrideUrlLoading method to launch the URL in a browser versus using your webview to handle the link:
webView.setWebViewClient(new WebViewClient(){
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (url != null && url.startsWith("http://")) {
view.getContext().startActivity(
new Intent(Intent.ACTION_VIEW, Uri.parse(url)));
return true;
} else {
return false;
}
}
}
If you want to load in the webview use:
WebViewClient yourWebClient = new WebViewClient()
{
// Override page so it's load on my view only
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url)
{
// This line we let me load only pages with an anchor tag
if ( url.contains("url") == true )
//Load new URL Don't override URL Link
return false;
// Return true to override url loading (In this case do nothing).
return true;
}
};
