Open webview in app when clicking on Textview
I used android:autolink="web"
in textview
to display text as links when it's a link. It is currently working fine and when you click on this link, it opens on the default browser for phones. I currently have a Webview in my activity. I need to open a url in my webview when I clicked on it. is there a way to achieve this?

You need to create a class that extends WebViewClient and overrides the toOverrideUrlLoading method, for example:
private class MyBrowser extends WebViewClient {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
}
then you have to set the WebView client to the object of the created class:
webView.setWebViewClient(new MyBrowser());
To view the full text of the page, you need to add the following properties:
webView.getSettings().setLoadsImagesAutomatically(true);
webView.getSettings().setJavaScriptEnabled(true);
webView.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);
To open your URL in a WebView, you need to add properties to the TextView, for example:
android:onClick="onUrlClick"
android:linksClickable="false"
android:clickable="true"
and then override the onClick method in the TextView like:
public void onUrlClick(final View view) {
TextView textView = (TextView)view;
String sUrl = String.valueOf(textView.getText());
webView.loadUrl(sUrl);
}
You may need to add an internet prefect
<uses-permission android:name="android.permission.INTERNET" />

private WebView webView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_my);
webView = (WebView) findViewById(R.id.webView);
webView.setWebViewClient(new MyBrowser());
webView.getSettings().setLoadsImagesAutomatically(true);
webView.getSettings().setJavaScriptEnabled(true);
webView.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);
}
public void onUrlClick(final View view) {
TextView textView = (TextView)view;
String sUrl = String.valueOf(textView.getText());
webView.loadUrl(sUrl);
}
private class MyBrowser extends WebViewClient {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
