How to get loaded web page title in Android WebView?
I'm using a WebView in my application, I have a requirement to change the app title based on the page user is on. How can I do this in Android WebView?
I did this in iphone by following line
self.title = [webPage stringByEvaluatingJavaScriptFromString:@"document.title"]
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Adds Progrss bar Support
this.getWindow().requestFeature(Window.FEATURE_PROGRESS);
setContentView(R.layout.webview );
// Makes Progress bar Visible
getWindow().setFeatureInt( Window.FEATURE_PROGRESS, Window.PROGRESS_VISIBILITY_ON);
mWebView = (WebView) findViewById( R.id.webview ); //This is the id you gave
//to the WebView in the main.xml
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.getSettings().setSupportZoom(true); //Zoom Control on web (You don't need this
//if ROM supports Multi-Touch
mWebView.getSettings().setBuiltInZoomControls(true); //Enable Multitouch if supported by ROM
// Load URL
Bundle b = getIntent().getExtras();
String url = b.getString("url");
Log.d(TAG, "url " + url);
mWebView.loadUrl(url);
// Sets the Chrome Client, and defines the onProgressChanged
// This makes the Progress bar be updated.
mWebView.setWebChromeClient(new WebChromeClient() {
public void onProgressChanged(WebView view, int progress){
//Make the bar disappear after URL is loaded, and changes string to Loading...
myActivity.setTitle("Loading...");
myActivity.setProgress(progress * 100); //Make the bar disappear after URL is loaded
// Return the app name after finish loading
if(progress == 100)
myActivity.setTitle(R.string.app_name);
}
});
mWebView.setWebViewClient(new WebViewClient(){
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
// return super.shouldOverrideUrlLoading(view, url);
}
@Override
public void onLoadResource(WebView view, String url) {
// TODO Auto-generated method stub
super.onLoadResource(view, url);
}
@Override
public void onPageFinished(WebView view, String url) {
super.onPageFinished(view, url);
ImageView logoImageView = (ImageView)findViewById(R.id.logoimage);
logoImageView.setVisibility(View.GONE);
Log.d(TAG, "view.getTitle() " + view.getTitle());
myActivity.setTitle(view.getTitle());
}
});
}
Solution 1:
You'll have to use a custom WebViewClient to get this done. You will override the onPageFinished() method so when a new page finishes loading you can set the webview to the appropriate title.
Below is a sample implementation of the above:
WebView mWebView = (WebView) findViewById(R.id.mwebview);
mWebView.setWebViewClient(new WebViewClient() {
@Override
public void onPageFinished(WebView view, String url) {
ExperimentingActivity.this.setTitle(view.getTitle());
}
});
You're a going to do that where you're initializing your webview. Replace the "ExperimentingActivity" to whatever you activity's name is.
If you're already overriding the WebViewClient, just add this function or the code inside to your already existing function.
You can get more info on the classes and functions I'm using here at:
Android Developers: Activity - setTitle()

Solution 2:
My observation is that, you get the webpage title using WebChromeClient
in lesser time than using WebViewClient
webview.setWebChromeClient(new WebChromeClient() {
@Override
public void onReceivedTitle(WebView view, String title) {
super.onReceivedTitle(view, title);
if (!TextUtils.isEmpty(title)) {
YourActivity.this.setTitle(title);
}
}
});
Solution 3:
Simplest way to read title of page in Kotlin :
webView.webViewClient = object : WebViewClient() {
//....
override fun onPageFinished(view: WebView, url: String) {
val title = view.title
}
//...
}
Solution 4:
private WebViewClient mWvClient = new WebViewClient() {
@Override
public void doUpdateVisitedHistory(WebView view, String url, boolean isReload) {
String title = view.getTitle();//getTitle
super.doUpdateVisitedHistory(view, url, isReload);
}
}
