I'm trying to add multiple links in a textview similar to what Google & Flipboard has done below with their Terms and conditions AND Privacy Policy shown in the screen shot below:
So far I've stumbled on using this approach
textView.setText(Html.fromHtml(myHtml); textView.setMovementMethod(LinkMovementMethod.getInstance());
where myHtml is a href.
But it doesn't give me control I need eg to launch a fragment etc.
Any idea how they achieve this in the two examples below?
I think that I'm a little late to share this, but I have 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:
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" /> //#C36241 - Rust
And this looks like this:
Hope it helps someone. :)
You can use Linkify ( android.text.Spannable , java.util.regex.Pattern , java.lang.String )
String termsAndConditions = getResources().getString(R.string.terms_and_conditions);
String privacyPolicy = getResources().getString(R.string.privacy_policy);
legalDescription.setText(
String.format(
getResources().getString(R.string.message),
termsAndConditions,
privacyPolicy)
);
legalDescription.setMovementMethod(LinkMovementMethod.getInstance());
Pattern termsAndConditionsMatcher = Pattern.compile(termsAndConditions);
Linkify.addLinks(legalDescription, termsAndConditionsMatcher, "terms:");
Pattern privacyPolicyMatcher = Pattern.compile(privacyPolicy);
Linkify.addLinks(legalDescription, privacyPolicyMatcher, "privacy:");
and then you can use the scheme to start an activity for example by adding the scheme in the AndroidManifest :
<intent-filter>
<category android:name="android.intent.category.DEFAULT" />
<action android:name="android.intent.action.VIEW" />
<data android:scheme="terms" />
<data android:scheme="privacy" />
</intent-filter>
If you want to do a custom action, you can set the intent-filter to your current activity, which will have a singleTop launchmode.
This will cause onNewIntent to be fired where can make your custom actions:
@Override
protected void onNewIntent(final Intent intent) {
...
if (intent.getScheme().equals(..)) {
..
}
}
Here's my solution:
First we need to have clickable links in our TextView:
Here's my TextView in the xml layout, do not add any links handling parameters.
<TextView android:id="@+id/sign_up_privacy" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/terms_and_privacy"/>
In strings file, I added the resource text with html tags
<string name="terms_and_privacy">By signing up you agree to our <a href="terms:">Terms of Service</a> and <a href="privacy:">Privacy Policy.</a></string>
In onCreateView set LinkMovementMethod to the TextView
TextView privacyTextView = (TextView) root.findViewById(R.id.sign_up_privacy); privacyTextView.setMovementMethod(LinkMovementMethod.getInstance());
Now the TextView links are clickable.
Second, We need to Handle these clicks:
In my Manifest file, I added intent-filter for "terms" and "privacy" and Single Instance Launch Mode
<activity android:name=".MyActivity" android:launchMode="singleInstance"> <intent-filter> <category android:name="android.intent.category.DEFAULT"/> <action android:name="android.intent.action.VIEW"/> <data android:scheme="terms"/> <data android:scheme="privacy"/> </intent-filter> </activity>
In MyActivity, override onNewIntent to catch privacy and terms intents
@Override protected void onNewIntent(Intent intent) { if (intent.getScheme().equalsIgnoreCase(getString("terms"))) { //handle terms clicked } else if (intent.getScheme().equalsIgnoreCase(getString("privacy"))) { //handle privacy clicked } else { super.onNewIntent(intent); } }
The best way to do this is with string file
In string.xml
<string name="agree_to_terms">I agree to the %1$s and %2$s</string>
<string name="terms_of_service">Terms of Service</string>
<string name="privacy_policy">Privacy Policy</string>
In onCreateView call below method
private void setTermsAndCondition() {
String termsOfServicee = getString(R.string.terms_of_service);
String privacyPolicy = getString(R.string.privacy_policy);
String completeString = getString(R.string.agree_to_terms, termsOfServicee,privacyPolicy);
int startIndex = completeString.indexOf(termsOfServicee);
int endIndex = startIndex + termsOfServicee.length();
int startIndex2 = completeString.indexOf(privacyPolicy);
int endIndex2 = startIndex2 + privacyPolicy.length();
SpannableStringBuilder spannableStringBuilder = new SpannableStringBuilder(completeString);
ClickableSpan clickOnTerms = new ClickableSpan() {
@Override
public void onClick(View widget) {
Toast.makeText(this, "click on terms of service", Toast.LENGTH_SHORT).show();
}
@Override
public void updateDrawState(TextPaint ds) {
ds.setColor(ContextCompat.getColor(this, R.color.blue));
}
};
ClickableSpan clickOnPrivacy = new ClickableSpan() {
@Override
public void onClick(View widget) {
Toast.makeText(this, "click on privacy policy", Toast.LENGTH_SHORT).show();
}
@Override
public void updateDrawState(TextPaint ds) {
ds.setColor(ContextCompat.getColor(this, R.color.blue));
}
};
spannableStringBuilder.setSpan(clickOnTerms, startIndex, endIndex, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
spannableStringBuilder.setSpan(clickOnPrivacy, startIndex2, endIndex2, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
yourTextView.setText(spannableStringBuilder);
yourTextView.setMovementMethod(LinkMovementMethod.getInstance());
}
With Textoo , this can be achieved like:
res/values/strings.xml:
<resources>
<string name="str_terms_and_privacy">By signing up you agree to our <a href="terms:">Terms of Service</a> and <a href="privacy:">Privacy Policy.</a></string>
</resources>
res/layout/myActivity.xml:
<TextView
android:id="@+id/view_terms_and_privacy"
android:text="@string/str_terms_and_privacy"
/>
java/myPackage/MyActivity.java:
public class MyActivity extends Activity {
...
protected void onCreate(Bundle savedInstanceState) {
...
TextView termsAndPrivacy = Textoo
.config((TextView) findViewById(R.id.view_terms_and_privacy))
.addLinksHandler(new LinksHandler() {
@Override
public boolean onClick(View view, String url) {
if ("terms:".equals(url)) {
// Handle terms click
return true; // event handled
} else if ("privacy:".equals(url)) {
// Handle privacy click
return true; // event handled
} else {
return false; // event not handled. continue default processing i.e. launch web browser and display the link
}
}
})
.apply();
...
}
...
}
This approach have the advantages that:
LinksHandler
and no need to define additional intent filterThis is working for me :
in xml :
<TextView
android:id="@+id/tv_by_continuing_str"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="8dp"
android:layout_marginLeft="8dp"
android:layout_marginRight="8dp"
android:textSize="15sp"
tools:text="Test msg 1 2, 3"
android:textColor="@color/translucent_less_white3"
android:textColorLink="@color/white"
android:gravity="center|bottom"
android:layout_above="@+id/btn_privacy_continue" />
In strings.xml
< string name="by_continuing_str2">< ! [ CDATA[By continuing to use this app, you agree to our <a href="https://go.test.com" style="color:gray"/> Privacy Statement </a> and <a href="https://go.test.com" style="color:gray"/>Services Agreement.]]>< / string>
in the activity :
TextView tv_by_continuing = (TextView) findViewById(R.id.tv_by_continuing);
tv_by_continuing.setText(Html.fromHtml(getString(R.string.by_continuing_str2)));
tv_by_continuing.setMovementMethod(LinkMovementMethod.getInstance());
An easy fix for this would be to use multiple labels. One for each link and one for the text.
[TermsOfServiceLabel][andLabel][PrivacyPolicy]
Or is it necessary that you only use one label?
private fun customTextView(view: TextView) {
//I agree to the Terms of service & Privacy Policy,
val spanTxt = SpannableStringBuilder(
"I agree to the ")
spanTxt.append("Terms of service")
spanTxt.setSpan(object : ClickableSpan() {
override fun onClick(widget: View) {
toast("Terms of service link clicked")
}
}, spanTxt.length - "Term of services".length, spanTxt.length, 0)
spanTxt.append(" and")
spanTxt.append(" Privacy Policy")
spanTxt.setSpan(object : ClickableSpan() {
override fun onClick(widget: View) {
toast("Privacy Policy link clicked")
}
}, spanTxt.length - " Privacy Policy".length, spanTxt.length, 0)
view.movementMethod = LinkMovementMethod.getInstance()
view.setText(spanTxt, TextView.BufferType.SPANNABLE)
}
