Hyperlink in RecyclerView textview

Question

I am fetching data from JSON and displaying in RecyclerView layout. My textview is displaying whole link. For example, my TextView is install and the link is http://mydomin.com?id=2054656. In RecyclerView it should show only install text and when it is clicked then is should go to URL. I tried below code.

Viewholder.ImageUrlNameView.setText(getDataAdapter1.getImageUrlName());

ImageUrlNameView = (TextView) itemView.findViewById(tvAppLink) ;

ImageUrlNameView.setMovementMethod(LinkMovementMethod.getInstance());

It's working fine but showing whole link instead of text. I hope you understand.

please see my full code after changing textview to button

please check the image what i am trying to get but getting error

what is sample output of `getDataAdapter1.getImageUrlName()`? Is it `text `or `URL`. whatever it is will be, it will set to your `ImageUrlNameView` as per your code. — Nitesh Verma, Oct 26 '16 at 18:57
its url fetch from database. its displaying whole link, i just want to show a text. on click the text it will go to url page — Asesha George, Oct 26 '16 at 19:02
you should do it like http://stackoverflow.com/a/14517468/3758972. with `HTML` — Nitesh Verma, Oct 26 '16 at 19:07
If you don't want to show a hyperlink your better off making a button with an onclick that opens the browser. Just pass it the url — Xjasz, Oct 26 '16 at 19:08
i tried button, but startActivity showing error. please see my full code. — Asesha George, Oct 27 '16 at 12:07
ImageUrlNameView gets url. do i need to convert or anything. i have no idea. ImageUrlNameView = (Button) itemView.findViewById(R.id.bAppUrl) ; displaying whole url. — Asesha George, Oct 27 '16 at 16:28

Change the logic of click into onBindViewHolder this way, you have the URL of the current object:

 @Override
        public void onBindViewHolder(ViewHolder Viewholder, int position) {

            GetDataAdapter getDataAdapter1 =  getDataAdapter.get(position);

            imageLoader1 = ServerImageParseAdapter.getInstance(context).getImageLoader();

            imageLoader1.get(getDataAdapter1.getImageServerUrl(),
                    ImageLoader.getImageListener(
                            Viewholder.networkImageView,//Server Image
                            R.mipmap.ic_launcher,//Before loading server image the default showing image.
                            android.R.drawable.ic_dialog_alert //Error image if requested image dose not found on server.
                    )
            );

            Viewholder.networkImageView.setImageUrl(getDataAdapter1.getImageServerUrl(), imageLoader1);

            Viewholder.ImageTitleNameView.setText(getDataAdapter1.getImageTitleName());

            Viewholder.ImageUrlNameView.setText("Install");



Viewholder.ImageUrlNameView.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View view) {
                        String url = getDataAdapter1.getImageUrlName();

                        Intent intent = new Intent(Intent.ACTION_VIEW);
                        intent.setData(Uri.parse(url));
                        context.startActivity(intent);
                    }
                });

        }

        @Override
        public int getItemCount() {

            return getDataAdapter.size();
        }

        class ViewHolder extends RecyclerView.ViewHolder{

            public NetworkImageView networkImageView ;
            public TextView ImageTitleNameView;
            public Button ImageUrlNameView ;

            public ViewHolder(View itemView) {

                super(itemView);

                networkImageView = (NetworkImageView) itemView.findViewById(R.id.VollyNetworkImageView1) ;
                ImageTitleNameView = (TextView) itemView.findViewById(R.id.textView_item);
                ImageUrlNameView = (Button) itemView.findViewById(R.id.bAppUrl) ;
                //ImageUrlNameView.setMovementMethod(LinkMovementMethod.getInstance());
                //Linkify.addLinks(ImageUrlNameView, Linkify.WEB_URLS);




            }


        }

small correction its context.startActivity(intent); not my idea. its suggested. working grate. thank you to all — Asesha George, Oct 27 '16 at 16:59

karthik prasad · Answer 2 · 2016-10-27T14:59:25.007

METHOD 1: Try this which worked for me- 1) String installString = "install"; String hyperlinkString = "Whatever string " + installString + " text"; SpannableString hyperlinkText = makeHyperlinkText(hyperlinkString, installString); textView.setText(hyperlinkText); textView.setMovementMethod(LinkMovementMethod.getInstance());

2) the function is here :

private SpannableString makeHyperlinkText(String hyperlinkString, String textToMakeHyperlink) {
        SpannableString content = new SpannableString(hyperlinkString);
        ClickableSpan clickableSpan = new ClickableSpan() {
            @Override
            public void onClick(View widget) {
                Intent webviewIntent = new Intent(YourCurrentActivity.this, WebviewActivity.class);
                webviewIntent.putExtra("URL", your_url_here); //EDIT
                startActivity(webviewIntent);
                }
            };
            int startIndex = hyperlinkString.indexOf(textToMakeHyperlink);
            int endIndex = startIndex + textToMakeHyperlink.length();
            content.setSpan(clickableSpan, startIndex, endIndex, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
            return content;
    }

//EDIT: added these files below

3) WebviewActivity class is here -

public class WebviewActivity extends AppCompactActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.your_webview_layout);

        String url = getIntent().getStringExtra("URL");

        getSupportActionBar().setDisplayHomeAsUpEnabled(true);

        WebView myWebView = (WebView) findViewById(R.id.webview);
        WebSettings webSettings = myWebView.getSettings();
        webSettings.setJavaScriptEnabled(true);

        myWebView.loadUrl(url);
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        switch (item.getItemId()) {
            case android.R.id.home:
                onBackPressed();
                return true;
        }
        return super.onOptionsItemSelected(item);
    }
}

4) Webview Layour class (customize as needed):

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.massmutual.css.ui.loan.LoanDisclosureWebView">

    <WebView  xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/webview"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        />

</RelativeLayout>

METHOD 2: You can change the way you pass the url string. It needs to be HTML format. Eg:

<a href="www.google.com">Click here for google.</a>

So i think your text would be something like :

    String url = "http://mydomin.com?id=2054656";
    String text = "install";
    String hyperlinkText = "<a href=\"" + url + "\""> + text + "</a>";

Let me know if these work for you.

not working. please see my code i have change textview to button. — Asesha George, Oct 27 '16 at 12:01
ok see i am getting url from json and set into ImageUrlNameView string. now when i use ImageUrlNameView = (Button) itemView.findViewById(R.id.bAppUrl) ; its replacing the text with url. its fine but i dont want to show the url. when i click on install string it should go to the url. you did a grate job. but i cannot change the script , i am not good in android — Asesha George, Oct 27 '16 at 15:05
