Capture http link click event in android textview

I have a link in android textview. I am not able to capture the link click event.
String text = "http:://www.google.com is a google link";
textview.setText(text);
"http:://www.google.com" this span of string is clickable in textview. I want to capture that particular click event.
I tried the following.
public static void setTextView(TextView text, CharSequence sequence) {
UoloLogger.i(TAG, "Setting string :: "+sequence);
SpannableStringBuilder strBuilder = new SpannableStringBuilder(sequence);
URLSpan[] urls = strBuilder.getSpans(0, sequence.length(), URLSpan.class);
for(URLSpan span : urls) {
makeLinkClickable(strBuilder, span);
}
text.setText(strBuilder);
text.setMovementMethod(LinkMovementMethod.getInstance());
}
public static void makeLinkClickable(SpannableStringBuilder strBuilder, final URLSpan span) {
int start = strBuilder.getSpanStart(span);
int end = strBuilder.getSpanEnd(span);
int flags = strBuilder.getSpanFlags(span);
ClickableSpan clickable = new ClickableSpan() {
public void onClick(View view) {
UoloLogger.i(TAG, span.getURL());
}
};
strBuilder.setSpan(clickable, start, end, flags);
strBuilder.removeSpan(span);
}
I started setting text into my textview using setTextView() method. I am getting URLSpan array is empty even if i am having the links.
String text = "http:://www.google.com is a google link";
setTextView(textView, text);
Sorry for the bad english. I think, i have explained my problem. Can someone help me.

public static void setLinkclickEvent(TextView tv, HandleLinkClickInsideTextView clickInterface) {
String text = tv.getText().toString();
String str = "([Hh][tT][tT][pP][sS]?:\\/\\/[^ ,'\">\\]\\)]*[^\\. ,'\">\\]\\)])";
Pattern pattern = Pattern.compile(str);
Matcher matcher = pattern.matcher(tv.getText());
while (matcher.find()) {
int x = matcher.start();
int y = matcher.end();
final android.text.SpannableString f = new android.text.SpannableString(
tv.getText());
InternalURLSpan span = new InternalURLSpan();
span.setText(text.substring(x, y));
span.setClickInterface(clickInterface);
f.setSpan(span, x, y,
android.text.Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
tv.setText(f);
}
tv.setLinksClickable(true);
tv.setMovementMethod(LinkMovementMethod.getInstance());
tv.setFocusable(false);
}
public static class InternalURLSpan extends android.text.style.ClickableSpan {
private String text;
private HandleLinkClickInsideTextView clickInterface;
#Override
public void onClick(View widget) {
getClickInterface().onLinkClicked(getText());
}
public void setText(String textString) {
this.text = textString;
}
public String getText() {
return this.text;
}
public void setClickInterface(HandleLinkClickInsideTextView clickInterface) {
this.clickInterface = clickInterface;
}
public HandleLinkClickInsideTextView getClickInterface() {
return this.clickInterface;
}
}
public interface HandleLinkClickInsideTextView {
public void onLinkClicked(String url);
}
After this i just used the method send click event.
textview.setText("http://google.com is google website and http://youtube.com is youtube site");
setLinkclickEvent(textview, new HandleLinkClickInsideTextView() {
public void onLinkClicked(String url) {
// Here I added my code
}
});

You can achieved the same using SpannableStringBuilder.
Simply initialize the TextView that you want to add 2 or more listeners and then pass that to the following method that I have created:
SAMPLE CODE:
private void customTextView(TextView view) {
SpannableStringBuilder spanTxt = new SpannableStringBuilder(
"I agree to the ");
spanTxt.append("Term of services");
spanTxt.setSpan(new ClickableSpan() {
#Override
public void onClick(View widget) {
Toast.makeText(getApplicationContext(), "Terms of services Clicked",
Toast.LENGTH_SHORT).show();
}
}, spanTxt.length() - "Term of services".length(), spanTxt.length(), 0);
spanTxt.append(" and");
spanTxt.setSpan(new ForegroundColorSpan(Color.BLACK), 32, spanTxt.length(), 0);
spanTxt.append(" Privacy Policy");
spanTxt.setSpan(new ClickableSpan() {
#Override
public void onClick(View widget) {
Toast.makeText(getApplicationContext(), "Privacy Policy Clicked",
Toast.LENGTH_SHORT).show();
}
}, spanTxt.length() - " Privacy Policy".length(), spanTxt.length(), 0);
view.setMovementMethod(LinkMovementMethod.getInstance());
view.setText(spanTxt, BufferType.SPANNABLE);
}
And in your XML, use android:textColorLink to add custom link color of your choice. Like this:
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="TextView"
android:textColorLink="#C36241" />

If you want to open a link after textview click, there are two options:
Using java code:
Spanned text = Html.fromHtml("<u>GOOGLE.COM</u>");
textView.setText(text);
Uri uri = Uri.parse("http://shopwhere.com.au/");
Intent webIntent = new Intent(Intent.ACTION_VIEW,uri);
// Create and start the chooser
Intent chooser = Intent.createChooser(webIntent, "Open with");
startActivityForResult(chooser,0);
Using XML:
Use android:autoLink="web" inside textview tag. You can also change link color android:textColorHighlight="#android:color/transparent" and android:textColorLink="#color/white".

How to set multiple click on textview android

I want to set multiple click on textview. I see many answers but any answer can't help me. I make spanned string using this code:-
private SpannableStringBuilder addClickablePart(String str) {
SpannableStringBuilder ssb = new SpannableStringBuilder(Html.fromHtml(deafultSpna + feelingSpan+tagfriendspan));
ssb.setSpan(new ClickableSpan() {
#Override
public void onClick(View widget) {
Toast.makeText(AddPostActivity.this, "hello click",
Toast.LENGTH_SHORT).show();
}
}, 0, Html.fromHtml(deafultSpna).length(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
ssb.setSpan(new ClickableSpan() {
#Override
public void onClick(View widget) {
Toast.makeText(AddPostActivity.this, "hello click ffff",
Toast.LENGTH_SHORT).show();
}
}, Html.fromHtml(deafultSpna).length(), Html.fromHtml(deafultSpna+feelingSpan).length(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
ssb.setSpan(new ClickableSpan() {
#Override
public void onClick(View widget) {
Toast.makeText(AddPostActivity.this, "hello click ffff fdsfds",
Toast.LENGTH_SHORT).show();
}
}, Html.fromHtml(deafultSpna+feelingSpan).length(), Html.fromHtml(deafultSpna+feelingSpan+tagfriendspan).length(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
return ssb;
}
but using this code I found like this view:-
But I want to like this:-
I make spanned using this codefeelingSpan = "<font color=#414141> - Feeling </font><font color=#bd2436>" + feeling_name + "</font>";
Any one can help me so solve this problem. Thanks in advance.

To make things easier, we can start by defining a small class that will make the clickable spans red and show the appropriate message when clicked.
private class MyClickableSpan extends ClickableSpan {
String text;
MyClickableSpan(String text) {
this.text = text;
}
#Override
public void updateDrawState(TextPaint ds) {
ds.setUnderlineText(false); // get rid of underlining
ds.setColor(Color.RED); // make links red
}
#Override
public void onClick(View view) {
Toast.makeText(view.getContext(), text, Toast.LENGTH_SHORT).show();
}
}
Next, we can add a small convenience method to create the clickable spans.
private void addClickableText(SpannableStringBuilder ssb, int startPos, String clickableText, String toastText) {
ssb.append(clickableText);
ssb.setSpan(new MyClickableSpan(toastText), startPos, ssb.length(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
}
Finally, we can fill the spannable string and display it.
TextView text = findViewById(R.id.text);
SpannableStringBuilder ssb = new SpannableStringBuilder("");
addClickableText(ssb, ssb.length(), "Abhishek Nagar", "hello click");
ssb.append(" - Feeling ");
addClickableText(ssb, ssb.length(), "Sad", "hello click ffff");
ssb.append(" with ");
addClickableText(ssb, ssb.length(), "Anand Jainb", "hello click ffff fdsfds");
text.setMovementMethod(LinkMovementMethod.getInstance()); // make our spans selectable
text.setText(ssb);
And that's all there is to it!

public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
TextView textView = findViewById(R.id.txt1);
textView.setMovementMethod(LinkMovementMethod.getInstance());
textView.setText(addClickablePart(getString(R.string.amanda_bio2)));
}
private SpannableStringBuilder addClickablePart(String str) {
SpannableStringBuilder ssb = new SpannableStringBuilder(str);
ssb.setSpan(new ClickableSpan() {
#Override
public void onClick(View widget) {
Toast.makeText(MainActivity.this, "span clicked 1", Toast.LENGTH_LONG).show();
}
#Override
public void updateDrawState(TextPaint ds) {
ds.setColor(Color.RED);
}
}, 200, 214, 0);
ssb.setSpan(new ClickableSpan() {
#Override
public void onClick(View widget) {
Toast.makeText(MainActivity.this, "span clicked 2", Toast.LENGTH_LONG).show();
}
#Override
public void updateDrawState(TextPaint ds) {
ds.setColor(Color.BLUE);
}
}, 241, 255, 0);
return ssb;
}
}
You can even add multiple spans and also customize its colors.

I Have Created a generalized function for this purpose hope this helps
fun TextView.makeLinks(vararg links: Triple<String, View.OnClickListener,LinkProperties>) {
try {
val spannableString = SpannableString(this.text)
for (link in links) {
val clickableSpan = object : ClickableSpan() {
override fun updateDrawState(textPaint: TextPaint) {
super.updateDrawState(textPaint)
textPaint.isUnderlineText = link.third.isUnderlineText
textPaint.isFakeBoldText = link.third.isBoldText
textPaint.color = link.third.color ?: Color.parseColor(DCColorPicker.BLACK)
}
override fun onClick(view: View) {
Selection.setSelection((view as TextView).text as Spannable, 0)
view.invalidate()
link.second.onClick(view)
}
}
val startIndexOfLink = this.text.toString().indexOf(link.first)
spannableString.setSpan(
clickableSpan, startIndexOfLink, startIndexOfLink + link.first.length,
Spanned.SPAN_EXCLUSIVE_EXCLUSIVE
)
}
this.movementMethod = LinkMovementMethod.getInstance() // without LinkMovementMethod, link can not click
this.setText(spannableString, TextView.BufferType.SPANNABLE)
} catch (e: Exception) {
Log.e(TAG, "makeLinks: " + e.message)
}
}
and you can add N no. of properties here
data class LinkProperties(val isUnderlineText: Boolean = false, val isBoldText: Boolean = false, val color: Int?=null)
and for calling you can use this function like this
val linkBoldOnly = LinkProperties(isBoldText = true)
val linkBoldUnderline = LinkProperties(isUnderlineText = true, isBoldText = true)
binding.name.makeLinks(
Triple("text", View.OnClickListener { openMore() }, linkBoldUnderline),
Triple(name.toString(), View.OnClickListener { itemClick() }, linkBoldOnly)
)

Set clicklistener on specific part of spannable textview in android

I am having a difficulty in setting a ClickListener in specific part of Text in SpannableTextView in android.
I have this text:
By registering you agree to the Terms And Services
I want to set clicklistener to the bold part only? Is it possible?

Yes, it's possible.
private void prepareTerms(){
String termsAndConditionsText = ...;
String discoverTermsText = ...;
SpannableString ss = new SpannableString(discoverTermsText);
int index = discoverTermsText.indexOf(termsAndConditionsText);
ss.setSpan(
new ClickableSpan() {
#Override
public void onClick(View widget) {
// open a webview here if you want
}
},
index,
index + termsAndConditionsText.length(),
SpannableString.SPAN_EXCLUSIVE_EXCLUSIVE
);
mTermAndCondTextView.setText(ss);
mTermAndCondTextView.setMovementMethod(LinkMovementMethod.getInstance());
}

SpannableStringBuilder builder = new SpannableStringBuilder();
builder.setSpan(new ClickableSpan() {
#Override
public void onClick(View widget) {
// click function
}
}, start_index, end_index, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
textview.setText(builder);

Try this code :
String text1 = "By registering you agree to the" + " ";
String text2 = "Terms And Services";
SpannableString spannableString = new SpannableString(text1 + text2);
ClickableSpan clickableSpan = new ClickableSpan() {
#Override
public void onClick(View view) {
// listen click here
}
#Override
public void updateDrawState(TextPaint ds) {
super.updateDrawState(ds);
ds.setUnderlineText(true);
ds.setColor(Color.BLACK);
}
};
spannableString.setSpan(clickableSpan, text1.length(), text1.length() + text2.length(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
textview.setText(spannableString);
textview.setMovementMethod(LinkMovementMethod.getInstance());
textview.setHighlightColor(Color.BLACK);

You can use the method setSpan from the class android.text.Spannable
Complete example and necessary information provided in the official documentation
In your string "By registering you agree to the Terms And Services" start value would be 35 and end would be stringObj.length

Android ClickableSpan get text onClick()

I'm working on ClickableSpan in a TextView, and I'm trying to get the clicked span's text. This is my code.
// this is the text we'll be operating on
SpannableString text = new SpannableString("Lorem ipsum dolor sit amet");
// make "dolor" (characters 12 to 17) display a toast message when touched
ClickableSpan clickableSpan = new ClickableSpan() {
#Override
public void onClick(View view) {
// This will get "Lorem ipsum dolor sit amet", but I just want "dolor"
String text = ((TextView) view).getText().toString();
Toast.makeText(context, text, Toast.LENGTH_LONG).show();
}
};
text.setSpan(clickableSpan, 12, 17, 0);
As you can see, I set the clickablespan to the TextView from characters 12 to 17, and I want to get these characters in the onClick event.
Is there anyway I can do that? Or at least can I pass the 12, 17 parameter to onClick event?
Thank you!

try this:
public class LoremIpsumSpan extends ClickableSpan {
#Override
public void onClick(View widget) {
// TODO add check if widget instanceof TextView
TextView tv = (TextView) widget;
// TODO add check if tv.getText() instanceof Spanned
Spanned s = (Spanned) tv.getText();
int start = s.getSpanStart(this);
int end = s.getSpanEnd(this);
Log.d(TAG, "onClick [" + s.subSequence(start, end) + "]");
}
}

A little simpler, could also pass a model reference if necessary.
public class SpecialClickableSpan extends ClickableSpan {
String text;
public SpecialClickableSpan(String text){
super();
this.text = text;
}
#Override
public void onClick(View widget) {
Log.d(TAG, "onClick [" + text + "]");
}
}
Then call new SpecialClickableSpan("My Text")

Edited: previous code was wrong, this works
// make "dolor" (characters 12 to 17) display a toast message when touched
ClickableSpan clickableSpan = new ClickableSpan() {
#Override
public void onClick(View view) {
TextView textView = (TextView) view;
CharSequence charSequence = textView.getText();
if (charSequence instanceof Spannable) {
Spannable spannableText = (Spannable)charSequence;
ClickableSpan[] spans = spannableText.getSpans(0, textView.length(), ClickableSpan.class);
for (ClickableSpan span : spans) {
int start = spannableText.getSpanStart(span);
int end = spannableText.getSpanEnd(span);
Toast.makeText(MainActivity.this, charSequence.subSequence(start, end), Toast.LENGTH_LONG).show();
}
}
}
};

You can also use to make string spannable like this
String htmlLinkText = "Lorem ipsum <a href='http://www.google.com'>dolor</a> sit amet";
testView.setText(Html.fromHtml(htmlLinkText));
testView.setMovementMethod(LinkMovementMethod.getInstance());
CharSequence text = testView.getText();
if (text instanceof Spannable) {
int end = text.length();
Spannable sp = (Spannable) testView.getText();
URLSpan[] urls = sp.getSpans(0, end, URLSpan.class);
SpannableStringBuilder style = new SpannableStringBuilder(text);
style.clearSpans();//should clear old spans
for (URLSpan url : urls) {
CustomerTextClick click = new CustomerTextClick(url.getURL());
style.setSpan(click, sp.getSpanStart(url), sp.getSpanEnd(url), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
}
testView.setText(style);
}
and CustomerTextClick will be
private static class CustomerTextClick extends ClickableSpan {
private String mUrl;
CustomerTextClick(String url) {
mUrl = url;
}
#Override
public void onClick(View widget) {
// TODO Auto-generated method stub
//Toast.makeText(ctx, "hello google!",Toast.LENGTH_LONG).show();
// Do your action here
}
}
Tested and working code.

clickable word inside TextView in android

I have TextView with text that changed dynamically. This text contain strings like <a href='myWord'>myWord</a>. I want that after click to this "link" myWord appear in the EditText in the same activity.
This is my code:
txt.setText(Html.fromHtml("...<a href='link'>link</a>..."));
txt.setMovementMethod(LinkMovementMethod.getInstance());
It's work well for URLs inside href attribute, but there is an error for another format.
I found a lot of similar questions on the StackOverflow but all of them were about url links. In my app I want create "link" inside activity.
In general, I can change tag to some another if it's depend...
Please help me!
Thank you!
-----SOLVED-----
Thank you Jacob Phillips for idea!
May it will be interesting someone in future.
This is a code:
//This is my string;
String str = "<b>Text</b> which contains one <a href='#'>link</a> and another <a href='#'>link</a>";
//TextView;
TextView txt = new TextView(this);
//Split string to parts:
String[] devFull = data[v.getId()][1].split("<a href='#'>");
//Adding first part:
txt.append(Html.fromHtml(devFull[0]));
//Creating array for parts with links (they amount always will devFull.length-1):
SpannableString[] link = new SpannableString[devFull.length-1];
//local vars:
ClickableSpan[] cs = new ClickableSpan[devFull.length-1];
String linkWord;
String[] devDevFull = new String[2];
for(int i=1; i<devFull.length; i++){
//obtaining 'clear' link
devDevFull = devFull[i].split("</a>");
link[i-1] = new SpannableString(devDevFull[0]);
linkWord = devDevFull[0];
cs[i-1] = new ClickableSpan(){
private String w = linkWord;
#Override
public void onClick(View widget) {
// here you can use w (linkWord)
}
};
link[i-1].setSpan(cs[i-1], 0, linkWord.length(), 0);
txt.append(link[i-1]);
try{
txt.append(Html.fromHtml(devDevFull[1]));
}
catch(Exception e){}
}

This should do the trick. Just change your edittext's text in the OnClickListener. It may be able to be reduced but this should work.
private void foo() {
SpannableString link = makeLinkSpan("click here", new View.OnClickListener() {
#Override
public void onClick(View v) {
// respond to click
}
});
// We need a TextView instance.
TextView tv = new TextView(context);
// Set the TextView's text
tv.setText("To perform action, ");
// Append the link we created above using a function defined below.
tv.append(link);
// Append a period (this will not be a link).
tv.append(".");
// This line makes the link clickable!
makeLinksFocusable(tv);
}
/*
* Methods used above.
*/
private SpannableString makeLinkSpan(CharSequence text, View.OnClickListener listener) {
SpannableString link = new SpannableString(text);
link.setSpan(new ClickableString(listener), 0, text.length(),
SpannableString.SPAN_INCLUSIVE_EXCLUSIVE);
return link;
}
private void makeLinksFocusable(TextView tv) {
MovementMethod m = tv.getMovementMethod();
if ((m == null) || !(m instanceof LinkMovementMethod)) {
if (tv.getLinksClickable()) {
tv.setMovementMethod(LinkMovementMethod.getInstance());
}
}
}
/*
* ClickableString class
*/
private static class ClickableString extends ClickableSpan {
private View.OnClickListener mListener;
public ClickableString(View.OnClickListener listener) {
mListener = listener;
}
#Override
public void onClick(View v) {
mListener.onClick(v);
}
}

Better approach is
SpannableString ss = new SpannableString("Android is a Software stack");
ClickableSpan clickableSpan = new ClickableSpan() {
#Override
public void onClick(View textView) {
startActivity(new Intent(MyActivity.this, NextActivity.class));
}
};
ss.setSpan(clickableSpan, 22, 27, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
//where 22 and 27 are the starting and ending index of the String. Now word stack is clickable
// onClicking stack it will open NextActiivty
TextView textView = (TextView) findViewById(R.id.hello);
textView.setText(ss);
textView.setMovementMethod(LinkMovementMethod.getInstance());

You can use below code;
SpannableString myString = new SpannableString(Html.fromHtml("Please "+"<font color=\"#F15d36\"><u>"+"login"+"</u></font>" +" or "+ "<font color=\"#F15d36\"><u>"+"sign up"+ "</u></font>"+" to begin your YupIT experience"));
ClickableSpan clickableSpan = new ClickableSpan() {
#Override
public void onClick(View textView) {
Toast.makeText(getContext(),"dfsgvdfs",Toast.LENGTH_SHORT).show();
}
};
ClickableSpan clickableSpan1 = new ClickableSpan() {
#Override
public void onClick(View textView) {
Toast.makeText(getContext(),"dfsgvdfs",Toast.LENGTH_SHORT).show();
}
};
myString.setSpan(clickableSpan,6,12,Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
myString.setSpan(clickableSpan1,15,23,Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
myString.setSpan(new ForegroundColorSpan(Color.parseColor("#F15d36")),6, 12, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
myString.setSpan(new ForegroundColorSpan(Color.parseColor("#F15d36")),15,23, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
tvFound.setMovementMethod(LinkMovementMethod.getInstance());
tvFound.setText(myString);

The best workaround I know is to create your own Button class. You could make the Button have a transparent background so that only the text is seen by the user. Then when the Button is pressed down change the TextColor and TextStyle of the button to be a darker color and underlined. This will work exactly as a link does. You can then use startActivity to go to the appropriated activity. You should not use hyperlinks to connect to other activities within your application.

My personal opinion would be to make a second textview containing the text that you want to be your link. Then you could do your action in the onClick of this second textView . Also as zzzzzzzzzzz stated above, you could choose to change the font properties of that text to whatever you want once it has been clicked.

To make it full answer with mixing answers;
private void textAreaInit()
{
String str = "<a href='#'>Link 1</a> and <a href='#'>Link2</a> is here.";
TextView tv = mConfirmText;
String[] devFull = str.split("<a href='#'>");
tv.append(Html.fromHtml(devFull[0]));
SpannableString[] link = new SpannableString[devFull.length-1];
ClickableSpan[] cs = new ClickableSpan[devFull.length-1];
String linkWord;
String[] devDevFull = new String[2];
for(int i=1; i<devFull.length; i++)
{
//obtaining 'clear' link
devDevFull = devFull[i].split("</a>");
link[i-1] = new SpannableString(devDevFull[0]);
linkWord = devDevFull[0];
final String a = linkWord;
cs[i-1] = new ClickableSpan()
{
private String w = a;
#Override
public void onClick(View widget) {
if(w.equals("Link 1"))
{
Intent intent = new Intent(PrintPropertiesActivity.this, ViewerAcivity.class);
intent.putExtra("title", "Link1");
intent.putExtra("uri", "link1");
intent.putExtra("type", "1");
startActivity(intent);
}
else
{
Intent intent = new Intent(PrintPropertiesActivity.this, ViewerAcivity.class);
intent.putExtra("title", "Link2");
intent.putExtra("uri", "link2");
intent.putExtra("type", "2");
startActivity(intent);
}
}
};
link[i-1].setSpan(cs[i-1], 0, linkWord.length(), 0);
tv.append(link[i-1]);
try{
tv.append(Html.fromHtml(devDevFull[1]));
}
catch(Exception e){}
}
makeLinksFocusable(tv);
}
private void makeLinksFocusable(TextView tv) {
MovementMethod m = tv.getMovementMethod();
if ((m == null) || !(m instanceof LinkMovementMethod)) {
if (tv.getLinksClickable()) {
tv.setMovementMethod(LinkMovementMethod.getInstance());
}
}
}
