How to open any web link(without any URL scheme) in app's webview activity in-spite of default browser

Question

I have seen some good answers regarding to my question but none of the solutions is 100% correct. most of the solution says setting hyperlink with custom scheme and setting the same scheme in IntentFilter.

But I am developing a message app, User may send any random text like google.com, yahoo.com, etc. Now I set the property autoLink=true in xml so all google.com's becoming hyperlink and when user clicks on it is opening in web-browser. I want this behavior to be changed, so that when user clicks on any link it should open new webview which in an activity belongs same app.

Answer 1

Use the following code

public class MainActivity extends Activity {
    private ProgressBar progressBar;
    private WebView webView;

    @SuppressLint("SetJavaScriptEnabled")
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        progressBar = (ProgressBar) findViewById(R.id.progressBar);
        progressBar.setMax(100);

        webView = (WebView) findViewById(R.id.webView);
        webView.getSettings().setJavaScriptEnabled(true);
        webView.getSettings().setAllowContentAccess(true);
        webView.getSettings().setDomStorageEnabled(true);
        webView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);

        WebSettings settings = webView.getSettings();
        settings.setPluginState(WebSettings.PluginState.ON);
        settings.setUseWideViewPort(true);
        settings.setLoadWithOverviewMode(true);
        settings.setBuiltInZoomControls(true);
        settings.setSupportZoom(true);
        settings.setDisplayZoomControls(false);

        webView.setWebViewClient(new WebViewClientDemo());
        webView.setWebChromeClient(new WebChromeClientDemo());
        webView.loadUrl("http://business-new.zakoopi.com/#/login/signin");

    }

    private class WebViewClientDemo extends WebViewClient {
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            view.loadUrl(url);
            return true;
        }

        @Override
        public void onPageFinished(WebView view, String url) {
            super.onPageFinished(view, url);
            progressBar.setVisibility(View.GONE);
            progressBar.setProgress(100);
        }

        @Override
        public void onPageStarted(WebView view, String url, Bitmap favicon) {
            super.onPageStarted(view, url, favicon);
            progressBar.setVisibility(View.VISIBLE);
            progressBar.setProgress(0);
        }
    }

    private class WebChromeClientDemo extends WebChromeClient {
        public void onProgressChanged(WebView view, int progress) {
            progressBar.setProgress(progress);
        }


        @Override
        public boolean onJsAlert(WebView view, String url, String message,JsResult result) {
            //Required functionality here
            return super.onJsAlert(view, url, message, result);
        }

    }


}

You may need to use Linkify here.

String text = "These are some sample links:some random links";
Spannable spannable = new SpannableString( Html.fromHtml(text) );
Linkify.addLinks(spannable, Linkify.WEB_URLS);

Now you have to listen to the clicks. You can do that like this.

URLSpan[] spans = spannable.getSpans(0, spannable.length(), URLSpan.class);
for (URLSpan urlSpan : spans) {
    LinkSpan linkSpan = new LinkSpan(urlSpan.getURL());
    int spanStart = spannable.getSpanStart(urlSpan);
    int spanEnd = spannable.getSpanEnd(urlSpan);
    spannable.setSpan(linkSpan, spanStart, spanEnd, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
    spannable.removeSpan(urlSpan);
}

Also Create the LinkSpan class

 private class LinkSpan extends URLSpan {
        private LinkSpan(String url) {
            super(url);
        }

        @Override
        public void onClick(View view) {
            String url = getURL();
            if (url != null) {

            startActivity(new Intent(LinkTestActivity.this,YourWebactivity.class).putExtra("url",url));

        }
    }
}

This solution actually worked for me. But Onclick event is triggering twice, But I am handling it.

private boolean isClickingLink = false;

TextView textView = (TextView) findViewById(R.id.main_text); textView.setMovementMethod(LinkMovementMethod.getInstance());

CharSequence charSequence = textView.getText();
SpannableStringBuilder sp = new SpannableStringBuilder(charSequence);

URLSpan[] spans = sp.getSpans(0, charSequence.length(), URLSpan.class);

for (URLSpan urlSpan : spans) {
    CustomSpan customSpan= new CustomSpan (urlSpan.getURL());
    sp.setSpan(customSpan, sp.getSpanStart(urlSpan),
            sp.getSpanEnd(urlSpan), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
}

textView.setText(sp);

textView.setOnClickListener(new OnClickListener() {

    @Override
    public void onClick(View v) {
        // 2.if clicking a link
        if (!isClickingLink) {
            Log.w("log", "not clicking link");
        }
        isClickingLink = false;
    }
});

private class CustomSpan extends ClickableSpan {

private String url;

public CustomSpan (String url) {

    super();
    thid.url= url;
}

@Override
public void onClick(View widget) {

    isClickingLink = true;
}

}
