如何使 TextView 中的链接可点击

Question

I have the following TextView defined:

<TextView 
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" android:text="@string/txtCredits"
    android:autoLink="web" android:id="@+id/infoTxtCredits"
    android:layout_centerInParent="true"
    android:linksClickable="true"/>

where @string/txtCredits is a string resource that contains <a href="some site">Link text</a> .

Android is highlighting the links in the TextView, but they do not respond to clicks. What am I doing wrong? Do I have to set an onClickListener for the TextView in my activity for something as simple as this?

It looks like it has to do with the way I define my string resource.

This does not work:

<string name="txtCredits"><a href="http://www.google.com">Google</a></string>

But this does:

<string name="txtCredits">www.google.com</string>

Which is a bummer because I would much rather show a text link than show the full URL.

Answer 1

Buried in the API demos, I found the solution to my problem:

File Link.java :

    // text2 has links specified by putting <a> tags in the string
    // resource.  By default these links will appear but not
    // respond to user input.  To make them active, you need to
    // call setMovementMethod() on the TextView object.

    TextView t2 = (TextView) findViewById(R.id.text2);
    t2.setMovementMethod(LinkMovementMethod.getInstance());

I removed most of the attributes on my TextView to match what was in the demo.

<TextView
    android:id="@+id/text2"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/txtCredits"/>

That solved it. It is pretty difficult to uncover and fix.

Important : Don't forget to remove autoLink="web" if you are calling setMovementMethod() .

Answer 2

I'm using only android:autoLink="web" and it works fine. A click on the link opens the browser and shows the correct page.

One thing I could guess is that some other view is above the link. Something that is transparent fills the whole parent but don't displays anything above the link. In this case the click goes to this view instead of the link.

Answer 3

After spending some time with this, I have found that:

• android:autoLink="web" works if you have full links in your HTML. The following will be highlighted in blue and clickable:

• Some text <a href="http://www.google.com">http://www.google.com</a>
• Some text http://www.google.com

• view.setMovementMethod(LinkMovementMethod.getInstance()); will work with the following (will be highlighted and clickable):

• Some text <a href="http://www.google.com">http://www.google.com</a>
• Some text http://www.google.com
• Some text <a href="http://www.google.com">Go to Google</a>

Note that the third option has a hyperlink, but the description of the link (the part between the tags) itself is not a link. android:autoLink="web" does NOT work with such links.

• android:autoLink="web" if set in XML will override view.setMovementMethod(LinkMovementMethod.getInstance()); (ie; links of the third kind will be highlighted, but not clickable).

The moral of the story is use view.setMovementMethod(LinkMovementMethod.getInstance()); in your code and make sure you don't have android:autoLink="web" in your XML layout if you want all links to be clickable.

Answer 4

The above solutions didn't work for me, but the following did (and it seems a bit cleaner).
First, in the string resource, define your tag opening chevrons using the HTML entity encoding, ie:

<a href="http://www.google.com">Google</a>

And not :

<a href="http://www.google.com">Google</a>

In general, encode all the chevrons in the string like that. BTW, the link must start with http://

Then (as suggested here ) set this option on your TextView:

 android:linksClickable="true"

Finally, in code, do:

((TextView) findViewById(R.id.your_text_view)).setMovementMethod(LinkMovementMethod.getInstance());
((TextView) findViewById(R.id.your_text_view)).setText(Html.fromHtml(getResources().getString(R.string.string_with_links)));

That's it. No regular expressiones or other manual hacks are required.

Answer 5

I simply used this:

Linkify.addLinks(TextView, Linkify.ALL);

It makes the links clickable, given here .

Answer 6

If you want to add an HTML-like link, all you need to do is:

• add a resource HTML-like string:

   <string name="link"><a href="https://www.google.pl/">Google</a></string>

• add your view to the layout with no link-specific configuration at all:

   <TextView android:id="@+id/link" android:text="@string/link" />`

• add the appropriate MovementMethod programmatically to your TextView:

   mLink = (TextView) findViewById(R.id.link); if (mLink != null) { mLink.setMovementMethod(LinkMovementMethod.getInstance()); }

That's it! And yes, having options like "autoLink" and "linksClickable" working on explicit links only (not wrapped into HTML tags) is very misleading to me too...

Answer 7

The following should work for anyone who is looking for a combination of text and hyperlink within an Android app.

In string.xml :

<string name="applink">Looking for Digital Visiting card? 
<a href="https://play.google.com/store/apps/details?id=com.themarkwebs.govcard">Get it here</a>
</string>

Now you can utilise this string in any given View like this:

<TextView
    android:id="@+id/getapp"
    android:layout_width="match_parent"
    android:layout_height="50dp"
    android:gravity="center"
    android:textColor="@color/main_color_grey_600"
    android:textSize="15sp"
    android:text="@string/applink"/>

Now, in your Activity or Fragment, do the following:

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

By now, you don't require to set android:autoLink="web" or android:linksClickable="true" using this approach.

Answer 8

I added this line to the TextView : android:autoLink="web"
Below is an example of usage in a layout file.

layout.xml sample

    <TextView
        android:id="@+id/txtLostpassword"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:autoLink="email"
        android:gravity="center"
        android:padding="20px"
        android:text="@string/lostpassword"
        android:textAppearance="?android:attr/textAppearanceSmall" />

    <TextView
        android:id="@+id/txtDefaultpassword"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:autoLink="web"
        android:gravity="center"
        android:padding="20px"
        android:text="@string/defaultpassword"
        android:textAppearance="?android:attr/textAppearanceSmall" />

string.xml

<string name="lostpassword">If you lost your password please contact <a href="mailto:support@cleverfinger.com.au?Subject=Lost%20Password" target="_top">support@cleverfinger.com.au</a></string>

<string name="defaultpassword">User Guide <a href="http://www.cleverfinger.com.au/user-guide/">http://www.cleverfinger.com.au/user-guide/</a></string>

Answer 9

I hope this will help you;

String value = "<html>Visit my blog <a href=\"http://www.maxartists.com\">mysite</a> View <a href=\"sherif-activity://myactivity?author=sherif&nick=king\">myactivity</a> callback</html>";
TextView text = (TextView) findViewById(R.id.text);

text.setText(Html.fromHtml(value));
text.setMovementMethod(LinkMovementMethod.getInstance());

Answer 10

The easiest thing that worked for me was to use Linkify

TextView txt_Message = (TextView) view.findViewById(R.id.txt_message);
txt_Message.setText("This is link https://www.google.co.in/");
Linkify.addLinks(txt_Message, Linkify.WEB_URLS);

And it will automatically detect the web URLs from the text in the textview.

Answer 11

You only need to add this in the text view in XML:

<TextView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:autoLink="web"/>

Answer 12

Richard, next time, you should add this code under TextView at the layout XML instead.

android:autoLink="all"

This should be like this.

<TextView 
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" 
    android:text="@string/txtCredits"
    android:id="@+id/infoTxtCredits"
    android:autoLink="all"
    android:linksClickable="true">
</TextView>

You don't need to use this code ( t2.setMovementMethod(LinkMovementMethod.getInstance()); ) in order to make the link clickable.

Also, here's the truth: as long as you set the autoLink and the linksClickable , don't forget to add this at String.xml file so that the clickable link will work.

<string name="txtCredits"><a href="http://www.google.com">Google</a></string>

Answer 13

By using linkify :

Linkify takes a piece of text and a regular expression and turns all of the regex matches in the text into clickable links:

TextView textView = (TextView) findViewById(R.id.textView);
textView.setText("http://example.com");
Linkify.addLinks(textView, Linkify.WEB_URLS);

Don't forget to

import android.widget.TextView;

Answer 14

Manage Linkify text color also

tv_customer_care_no.setLinkTextColor(getResources().getColor(R.color.blue));
tv_customer_care_no.setText("For us to reach out to you, please fill the details below or contact our customer care at 18004190899 or visit our website http://www.dupont.co.in/corporate-links/contact-dupont.html");
Linkify.addLinks(tv_customer_care_no, Linkify.WEB_URLS | Linkify.PHONE_NUMBERS);
Linkify.addLinks(tv_customer_care_no, Linkify.ALL);

Answer 15

Here is a very one-line Android code to make phone and URL selectable from textView no matter what the string is and what the data is. You don't need to use any HTML tags for this.

TextView textView = (TextView)findViewById(R.id.textView1);
textView.setText("some URL is www.google.com phone 7504567890 another URL lkgndflg.com ");

// Makes the textView's Phone and URL (hyperlink) select and go.
Linkify.addLinks(textView, Linkify.WEB_URLS | Linkify.PHONE_NUMBERS);

Answer 16

I noticed that using android:autoLink="web" thus

<TextView
    android:layout_width="match_parent"
    android:layout_height="wrap_content" 
    android:autoLink="web"/>

worked OK for URLs but since I had an e-mail address and phone number that I wanted to link as well, I ended up using this line android:autoLink="all" like this

<TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content" 
        android:autoLink="all"/>

and it worked like a charm.

Answer 17

The accepted answer is correct, but it will mean that phone numbers, maps, email addresses, and regular links, eg, http://google.com without href tags will no longer be clickable since you can't have an autolink in the XML content.

The only complete solution to have everything clickable that I have found is the following:

Spanned text = Html.fromHtml(myString);
URLSpan[] currentSpans = text.getSpans(0, text.length(), URLSpan.class);
SpannableString buffer = new SpannableString(text);
Linkify.addLinks(buffer, Linkify.ALL);
for (URLSpan span : currentSpans) {
    int end = text.getSpanEnd(span);
    int start = text.getSpanStart(span);
    buffer.setSpan(span, start, end, 0);
}
textView.setText(buffer);
textView.setMovementMethod(LinkMovementMethod.getInstance());

And the TextView should not have android:autolink . There's no need for android:linksClickable="true" either; it's true by default.

Answer 18

You need only this:

android:autoLink="web"

Insert this line into a TextView that can be clickable with a reference to the web. The URL is set as a text of this TextView.

Example:

 <TextView
    android:id="@+id/textViewWikiURL"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textSize="20sp"
    android:textStyle="bold"
    android:text="http://www.wikipedia.org/"
    android:autoLink="web" />

Answer 19

务必不要使用setAutoLinkMask(Linkify.ALL)使用时setMovementMethod(LinkMovementMethod.getInstance())和Html.fromHTML()上正确格式HTML链接（例如， <a href="http://www.google.com/">Google</a> )。

Answer 20

Use this...

TextView.setOnClickListener(new OnClickListener() {

                    @Override
                    public void onClick(View v) {
                        // TODO Auto-generated method stub
                        Intent in=new Intent(Intent.ACTION_VIEW,Uri.parse("http://www.twitter.com/"));
                        startActivity(in);
                    }
                    
                });

And add a permission in the manifest file:

<uses-permission android:name="android.permission.INTERNET"/>

Answer 21

This is how I solved clickable and visible links in a TextView (by code)

private void setAsLink(TextView view, String url){
    Pattern pattern = Pattern.compile(url);
    Linkify.addLinks(view, pattern, "http://");
    view.setText(Html.fromHtml("<a href='http://" + url + "'>http://" + url + "</a>"));
}

Answer 22

Use the below code:

String html = "<a href=\"http://yourdomain.com\">Your Domain Name</a>"
TextView textview = (TextView) findViewById(R.id.your_textview_id);
textview.setMovementMethod(LinkMovementMethod.getInstance());
textview.setText(Html.fromHtml(html));

Answer 23

[Tested in Pre-lollipop as well as in Lollipop and above]

You can get your HTML string from the backend or from your resources files. If you put your text as an resource string, make sure to add the CDATA tag:

<string name="your_text">![CDATA[...<a href="your_link">Link Title</a>  ...]]</string>

Then in code you need to get the string and assign it as HTML and set a link movement method:

String yourText = getString(R.string.your_text);

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
   textView.setText(Html.fromHtml(yourText, Html.FROM_HTML_MODE_COMPACT));
} else {
   textView.setText(Html.fromHtml(yourText));
}

try {
   subtext.setMovementMethod(LinkMovementMethod.getInstance());
} catch (Exception e) {
   //This code seems to crash in some Samsung devices.
   //You can handle this edge case base on your needs.
}

Answer 24

I had to hunt this down in a couple places, but I finally got this version of the code to work.

File strings.xml :

<string name="name1">&lt;a href="http://www.google.com">link text1&lt;/a></string>
<string name="name2">&lt;a href="http://www.google.com">link text2&lt;/a></string>

File myactivity.xml :

<TextView
    android:id="@+id/textview1"
    android:layout_height="wrap_content"
    android:layout_width="wrap_content"
    android:layout_marginTop="5dp" />

<TextView
    android:id="@+id/textview2"
    android:layout_height="wrap_content"
    android:layout_width="wrap_content"
    android:layout_marginTop="5dp" />

File myactivty.java (in onCreate()):

TextView tv1 = (TextView)findViewById(R.id.textview1);
TextView tv2 = (TextView)findViewById(R.id.textview2);

tv1.setText(Html.fromHtml(getResources().getString(R.string.name1)));
tv2.setText(Html.fromHtml(getResources().getString(R.string.name2)));
tv1.setMovementMethod(LinkMovementMethod.getInstance());
tv2.setMovementMethod(LinkMovementMethod.getInstance());

This will create two clickable hyperlinks with the text link text1 and link text2 which redirect the user to Google.

Answer 25

The reason you're having the problem is that it only tries to match "naked" addresses. Things like "www.google.com" or "http://www.google.com".

Running your text through Html.fromHtml() should do the trick. You have to do it programmatically, but it works.

Answer 26

Add CDATA to your string resource

Strings.xml

<string name="txtCredits"><![CDATA[<a href=\"http://www.google.com\">Google</a>]]></string>

Answer 27

I just wasted so much time to figure out you have to use getText(R.string.whatever) instead of getString(R.string.whatever)...

Anyway, here is how I got mine working. With multiple hyperlinks in the same text view too.

TextView termsTextView = (TextView) getActivity().findViewById(R.id.termsTextView);
termsTextView.append("By registering your account, you agree to our ");
termsTextView.append(getText(R.string.terms_of_service));
termsTextView.append(", ");
termsTextView.append(getText(R.string.fees));
termsTextView.append(", and the ");
termsTextView.append(getText(R.string.stripe_connected_account_agreement));

termsTextView.setMovementMethod(LinkMovementMethod.getInstance());

<TextView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:id="@+id/termsTextView"/>

String example:

    <string name="stripe_connected_account_agreement"><a href="https://stripe.com/connect/account-terms">Stripe Connected Account Agreement</a></string>

Answer 28

Autolink phone did not work for me. The following worked like a charm,

TextView tv = (TextView) findViewById(R.id.emergencynos);
String html2="<br><br>Fire - <b><a href=tel:997>997</a> </b></br></br>";
tv.append(Html.fromHtml(html2));
tv.setMovementMethod(LinkMovementMethod.getInstance());

Answer 29

If using an XML-based TextView, for your requirement you need to do just two things:

1. Identify your link in the string, such as "this is my WebPage." You can add it in the XML content or in the code.

2. In the XML content that has the TextView, add these:

    android:linksClickable="true" android:autoLink="web"

Answer 30

Create an extension method on SpannableString:

private fun SpannableString.setLinkSpan(text: String, url: String) {
    val textIndex = this.indexOf(text)
    setSpan(
        object : ClickableSpan() {
            override fun onClick(widget: View) {
                Intent(Intent.ACTION_VIEW).apply { data = Uri.parse(url) }.also { startActivity(it) }
            }
        },
        textIndex,
        textIndex + text.length,
        Spanned.SPAN_EXCLUSIVE_EXCLUSIVE
    )
}

Use it to make string in your TextView clickable:

    myTextView.apply {
        movementMethod = LinkMovementMethod.getInstance()

        val googleUrl = "http://www.google.com"
        val microsoftUrl = "http://www.microsoft.com"

        val google = "Google"
        val microsoft = "Microsoft"

        val message = SpannableString("$google & $microsoft").apply {
            setLinkSpan(google, googleUrl)
            setLinkSpan(microsoft, microsoftUrl)
        }

        text = message
    }

Enjoy!

Answer 34

For those who are having issues with strings reading from XML content and assigning dynamically.

Answer 35

As the databinding is out, I'd like to share my solution for databinding TextViews supporting HTML tags with clickable links.

To avoid retrieving every textview and giving them html support using From.html we extend the TextView and put the logic in setText()

public class HtmlTextView extends TextView {

    public HtmlTextView(Context context) {
        super(context);
    }

    public HtmlTextView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public HtmlTextView(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }

    @Override
    public void setText(CharSequence text, BufferType type) {
        super.setText(Html.fromHtml(text.toString()), type);
        this.setMovementMethod(LinkMovementMethod.getInstance());
    }
}

I've made a gist which also shows example entity and view for using this.

Answer 36

Simply add this in your edittext

        android:autoLink="web"
        android:linksClickable="true"

if it doesn't work downvote my answer other wise 😉

Answer 37

You can simply add links to your TextView with Android's Linkify library .

Add to your strings.xml

<string name="text_legal_notice">By continuing, you confirm that you have read, understood and agreed to our %1$s and %2$s.</string>
<string name="text_terms_conditions">Terms &amp; Conditions</string>
<string name="text_privacy_policy">Privacy Policy</string>

Add to your activity

final String termsConditionsText = getString(R.string.text_terms_conditions);
final String privacyPolicyText = getString(R.string.text_privacy_policy);
final String legalText = getString(
        R.string.text_legal_notice,
        termsConditionsText,
        privacyPolicyText
);
viewBinding.textViewLegalNotice.setText(legalText);

Linkify.addLinks(
        viewBinding.textViewLegalNotice,
        Pattern.compile(termsConditionsText),
        null,
        null,
        (match, url) -> "https://policies.google.com/terms"
);
Linkify.addLinks(
        viewBinding.textViewLegalNotice,
        Pattern.compile(privacyPolicyText),
        null,
        null,
        (match, url) -> "https://policies.google.com/privacy"
);
