Link should be open in same web view in Android

You need to add WebViewClient to your WebView in order to open it in the WebView. Something like

myWebView.setWebViewClient(new WebViewClient() {
    @Override
    public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
        view.loadUrl(request.getUrl().toString());
        return false;
    }
});
