I'm using Android Studio to create an English language learning app and I want to make a few letters on a button bold but I cannot do it. For example I want the button to read "I like basketball" as the first syllable in basketball is emphasized when we pronounce the word.
However I cannot get this to work. Here is my strings.xml.
<string name="test">I like <b>bas</b>ketball</string>
And here is my activity.xml.
<Button
android:id="#+id/test"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/test"
android:textAllCaps="false" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#+string/test"
android:textAllCaps="false" />
</LinearLayout>
Neither the Button nor the TextView are recognizing the formatting.
I will have over 400 buttons that will require a different set of characters to be bold so I don't want to use spannable strings to code this.
Is there an easy solution?
1st Approach-
you string need to be updated to <string name="test">I like <b> bas</b>ketball.</string> if you are using string from String.xml
but you need to add below code in Activity class to work -
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
textView.setText(Html.fromHtml(getString(R.string.test), Html.FROM_HTML_MODE_LEGACY));
}else{
textView.setText(Html.fromHtml(getString(R.string.test));
}
2nd Approach-
Add below code in your String.xml file at top
<?xml version="1.0" encoding="utf-8"?>
Then add your string in resources -
<resources>
<string name="test"><![CDATA[I like <b> bas</b>ketball]]></string>
</resources>
and then in activity class set the HTML text like below -
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
textView.setText(Html.fromHtml(getString(R.string.test), Html.FROM_HTML_MODE_LEGACY));
}else{
textView.setText(Html.fromHtml(getString(R.string.test));
}
Hope this will help.
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 Link text.
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">Google</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.
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().
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.
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 http://www.google.com
Some text http://www.google.com
view.setMovementMethod(LinkMovementMethod.getInstance()); will work with the following (will be highlighted and clickable):
Some text http://www.google.com
Some text http://www.google.com
Some text Go to Google
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()); (i.e.; 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.
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, i.e.:
<a href="http://www.google.com">Google</a>
And not:
Google
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.
I simply used this:
Linkify.addLinks(TextView, Linkify.ALL);
It makes the links clickable, given here.
If you want to add an HTML-like link, all you need to do is:
add a resource HTML-like string:
<string name="link">Google</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...
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?
Get it here
</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.
I added this line to the TextView: android:autoLink="web"
Below is an example of usage in a layout file.
layout.xml
<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 support#cleverfinger.com.au</string>
<string name="defaultpassword">User Guide http://www.cleverfinger.com.au/user-guide/</string>
I hope this will help you;
String value = "<html>Visit my blog mysite View myactivity callback</html>";
TextView text = (TextView) findViewById(R.id.text);
text.setText(Html.fromHtml(value));
text.setMovementMethod(LinkMovementMethod.getInstance());
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.
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"/>
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);
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;
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">Google</string>
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);
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.
The accepted answer is correct, but it will mean that phone numbers, maps, email addresses, and regular links, e.g., 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.
Be sure to not use setAutoLinkMask(Linkify.ALL) when using setMovementMethod(LinkMovementMethod.getInstance()) and Html.fromHTML() on properly formatted HTML links (for example, Google).
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" />
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"/>
Add this to your EditText:
android:autoLink="web"
android:linksClickable="true"
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>"));
}
Use the below code:
String html = "Your Domain Name"
TextView textview = (TextView) findViewById(R.id.your_textview_id);
textview.setMovementMethod(LinkMovementMethod.getInstance());
textview.setText(Html.fromHtml(html));
[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[...Link Title ...]]</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.
}
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!
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"><a href="http://www.google.com">link text1</a></string>
<string name="name2"><a href="http://www.google.com">link text2</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.
Add CDATA to your string resource
Strings.xml
<string name="txtCredits"><![CDATA[Google]]></string>
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.
If using an XML-based TextView, for your requirement you need to do just two things:
Identify your link in the string, such as "this is my WebPage."
You can add it in the XML content or in the code.
In the XML content that has the TextView, add these:
android:linksClickable="true"
android:autoLink="web"
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">Stripe Connected Account Agreement</string>
I am a PHP programmer who is having to do some work in the android development environment. I have 2 books on this and have tried 30 search engine topics and still have not found just a simple example of everything that you need to do to place a working hyperlink in a Java android application.
I just need a very simple but complete ingredient for doing so. I have the 2.2 android development environment with Eclipse and an emulator. I have tried the WebView control which just simply loads a web site into the window when I run the application. I need a basic hyperlink to a web site example.
I don't want anything else thrown in with it (just an application with a working hyperlink and nothing else), because I am trying to learn the different controls bit by bit along with the Java and XML code that controls them.
This is so different from PHP, ASP, etc. that it has me totally fishing for answers. Thanks;

Android is a GUI, not a Web browser. Hence, "place a working hyperlink in a Java android application" is akin to "place a snowplow blade on a dishwasher" or "implement a Web app in COBOL". It is technically possible but probably is the incorrect solution to whatever problem it is that you really trying to solve.
So, as MatrixFrog indicates, one possibility is to use a TextView and some HTML:
TextView tv=(TextView)findViewById(R.id.whatever_you_called_it_in_your_layout);
tv.setText(Html.fromHtml("Who knows?"));
But, doing that would be unusual in a GUI environment. Most developers would use a button, or a menu choice, or something along those lines, to trigger viewing some URL.
CommonsWare, That is not what I call a detailed explanation or example of how to place a hyperlink inside an android application. It is just a small snippet of code with no further explanation. I found what works on my own and here is the Java code for it:
package com.practice.weblink;
import android.app.Activity;
import android.os.Bundle;
import android.text.util.Linkify;
import android.widget.TextView;
public class WebLink extends Activity
{
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
TextView textview = (TextView) findViewById(R.id.hyperlink);
Linkify.addLinks(textview, Linkify.WEB_URLS);
}
}
The TextView has the following qualities in the main.xml file:
<TextView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:text="#string/hyperlink"
android:id="#+id/hyperlink"
android:autoLink="web"
>
</TextView>
The strings.xml file looks like this:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="app_name">WebLink</string>
<string name="hyperlink">http://google.com</string>
</resources>
That is how you give a working example of something. Next time don't assume that people can just piece together what you are mentioning in your answer.
How about using onClick in the XML layout file?
layout.xml
<TextView
android:id="#+id/textView1"
android:layout_width="fill_parent"
android:layout_height="0dp"
android:clickable="true"
android:text="#string/market_url"
android:textColor="#00f"
android:onClick="openURL"
/>
MyActivity.java
public void openURL(View v) {
String url = ((TextView) v).getText().toString();
final Intent intent = new Intent(Intent.ACTION_VIEW).setData(Uri.parse(url));
startActivity(intent);
}
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 Link text.
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">Google</string>

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

// 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.

android:gravity="center"
android:textColor="#color/main_color_grey_600"

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

TextView text = (TextView) findViewById(R.id.text);
text.setText(Html.fromHtml(value));
text.setMovementMethod(LinkMovementMethod.getInstance());
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.
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"/>
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);
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;
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">Google</string>
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);
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.
The accepted answer is correct, but it will mean that phone numbers, maps, email addresses, and regular links, e.g., 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.
Be sure to not use setAutoLinkMask(Linkify.ALL) when using setMovementMethod(LinkMovementMethod.getInstance()) and Html.fromHTML() on properly formatted HTML links (for example, Google).
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" />
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"/>
Add this to your EditText:
android:autoLink="web"
android:linksClickable="true"
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>"));
}
Use the below code:
String html = "Your Domain Name"
TextView textview = (TextView) findViewById(R.id.your_textview_id);
textview.setMovementMethod(LinkMovementMethod.getInstance());
textview.setText(Html.fromHtml(html));
[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[...Link Title ...]]</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.
}
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!
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"><a href="http://www.google.com">link text1</a></string>
<string name="name2"><a href="http://www.google.com">link text2</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.
Add CDATA to your string resource
Strings.xml
<string name="txtCredits"><![CDATA[Google]]></string>
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.
If using an XML-based TextView, for your requirement you need to do just two things:
Identify your link in the string, such as "this is my WebPage."
You can add it in the XML content or in the code.
In the XML content that has the TextView, add these:
android:linksClickable="true"
android:autoLink="web"
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">Stripe Connected Account Agreement</string>
I'm looking for something like the individual parts of the date picker dialog. A view that allows you to input integers (and only integers) that you can limit (between 1 and 10 for example), where you can use the keyboard or the arrows in the view itself. Does it exists?
It is for a dialog. A ready-made dialog to request an integer would also help.
The NumberPicker widget is probably what you want. Unfortunately it's located in com.android.internal.Widget.NumberPicker which we cannot get to through normal means.
There are two ways to use it:
Copy the code from android source
Use reflection to access the widget
Here's the xml for using it in a layout:
<com.android.internal.widget.NumberPicker
android:id="#+id/picker"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
Here's the reflection to set the NumberPicker settings (I have not tested this):
Object o = findViewById(R.id.picker);
Class c = o.getClass();
try
{
Method m = c.getMethod("setRange", int.class, int.class);
m.invoke(o, 0, 9);
}
catch (Exception e)
{
Log.e("", e.getMessage());
}
Since it's an internal widget and not in the SDK, future compatibility could be broken if you use reflection. It would be safest to roll your own from the source.
The original source for this information is shared in this Google Group.
The NumberPicker internal widget has been pulled from the Android source code and packaged for your use and you can find it here. Works great!
EDIT: Original link is down, you can find a copy of the widget here
As has been mentioned elsewhere, NumberPicker is now available in the Android SDK as of API 11 (Android 3.0):
http://developer.android.com/reference/android/widget/NumberPicker.html
For Android < 3.0, you can use the code here:
https://github.com/novak/numpicker-demo
https://github.com/mrn/numberpicker
You can with EditText use android:inputType="number"
<EditText android:layout_height="wrap_content" android:id="#+id/editText1" android:inputType="number" android:layout_width="wrap_content"></EditText>
You can simply use an EditText and define inputType as number. E.g:
<EditText
android:id="#+id/etNumberInput"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="8dp"
android:inputType="number" />
To limit the maximum value to, say 10, you can do it programmatically as:
final EditText et = findViewById(R.id.etNumberInput);
et.addTextChangedListener(new TextWatcher() {
public void afterTextChanged(Editable s) {}
public void beforeTextChanged(CharSequence s, int start,
int count, int after) {}
public void onTextChanged(CharSequence s, int start,
int before, int count) {
if (Integer.parseInt(et.getText().toString()) > 10) {
et.setError("***Your error here***");
// your logic here; to limit the user from inputting
// a value greater than specified limit
}
}
});
This should meet your goal.
