webview inside Fragnent I want to open my site inside the webview, and the links inside the site should open outside

Question

REINFORCEMENT I AM OPENING WEBVIEW IN A FRAGMENT AND NOT IN MAIN ACTIVITY - I want to open my site inside the webview, and the links from other sites should open outside, in the normal mobile browser, but this does not occur. My webview is inside a Fragment. You can help me?

MY CODE :

@Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {

    View v = inflater.inflate(R.layout.fragment_principal, container, false);
    WebView webView = (WebView) v.findViewById(R.id.webview);
    webView.getSettings().setJavaScriptEnabled(true);

    WebViewClientImpl webViewClient = new WebViewClientImpl(this);

    //se eu desabilito essa linha resolve, porem tudo abre fora do app, e 
    //queria somente que os links listados no site abrissem fora.

    webView.setWebViewClient(new WebViewClient());
    webView.loadUrl("https://meusite.com/");

    return v;

}

    public class WebViewClientImpl extends WebViewClient {


        private PrincipalFragment activity = null;
        public WebViewClientImpl(PrincipalFragment activity) {
            this.activity = activity;
        }
        @Override
        public boolean shouldOverrideUrlLoading(WebView webView, String url) {
            if(url.contains("https://meusite.com")) return false;
            Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
            activity.startActivity(intent);

            return true;

        }

    }

Fragmente_principal.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"

    android:layout_height="match_parent"
    android:background="@android:color/holo_purple">

    <WebView
        android:id="@+id/webview"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

    </WebView>
</LinearLayout>

Following the way you implemented webview instead of:

webView.setWebViewClient(new WebViewClient());

the right is to instantiate the class you created that extends Webviewclient, then it would be:

webView.setWebViewClient(webViewClient);

The rest of your Fragment keeps.

In the Webviewclientimpl class let the override method look like this:

@Override
public boolean shouldOverrideUrlLoading(WebView webView, String url) {
    if(url.contains("https://meusite.com")) {
        return true;
    } else {
        Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
        activity.startActivity(intent);
        //Use o método a seguir caso, o seu webview continua carregando
        //as páginas que o browser deveria abrir (diferente do seu host) 
        webView.stopLoading();

        return false;
    }

}

Or you can override this method the way Guilherme Nascimento suggested:

@Override
public boolean shouldOverrideUrlLoading(WebView webView, String url) {

     Uri uri = Uri.parse(url);

    if(uri.getHost().equals("meusite.com")) {
        return true;
    } else {
        Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
        activity.startActivity(intent);
        //Use o método a seguir caso, o seu webview continua carregando
        //as páginas que o browser deveria abrir (diferente do seu host) 
        webView.stopLoading();

        return false;
    }

}

I hope I helped. And remember to change the urls.
