I am trying to improve accessibility for a text view used for terms and privacy policy which looks something like this:
As mentioned on the Google Support page, the user will need to access the Local Context Menu via a TalkBack gesture (default gesture is Swipe up then right) to activate a TextView link.
But I want to use a swipe gesture to navigate between links something like:
Currently, I am using clickable span to add the links, it is working fine with Local Context Menu but not with a swipe gesture.
My code looks something like this:
val clickableSpan: ClickableSpan = object : ClickableSpan() {
override fun onClick(widget: View) {
// handle link click.
}
}
val spannableStringBuilder = SpannableStringBuilder(text).apply {
setSpan(clickableSpan, 99, 109, Spannable.SPAN_INCLUSIVE_INCLUSIVE)
}
tv_term_and_privacy_policy.apply {
setText(spannableStringBuilder)
movementMethod = LinkMovementMethod.getInstance()
}
Please help me with this.

I am working on the accessibility and currently I want to set the Button Role on the MenuItem. We have checked but not got the proper solution for the same. I tried by setting the custom action layout and then giving the custom action layout Button Role it detect it as button but click need to be handled by setting the click listener on action layout. Which I want to avoid, is there any possibility that we can set role to MenuItem. So it will announce like "Setting Button Double Tap To Activate"
`#JvmStatic
fun View.setCustomRole(roleInfo: String) {
ViewCompat.setAccessibilityDelegate(this,
object : AccessibilityDelegateCompat() {
override fun onInitializeAccessibilityNodeInfo(
v: View,
info: AccessibilityNodeInfoCompat
) {
super.onInitializeAccessibilityNodeInfo(v, info)
info.roleDescription = roleInfo
}
})
}`
Tried above method by setting action layout which work but I need to change the click handling from app which I want to avoid.
This was answered fairly recently, however I think I can clean it up somewhat.
Option 1
You can make MenuItem's buttons by default by ensuring you have the latest material library imported.
implementation 'com.google.android.material:material:1.7.0'
The sample app I created for my answer was 1.5.0 and it still had the default "button" announcement.
Option 2
In Material 1.7.0:
I didn't need any of this code to achieve the solution to the question
onInitializeAccessibilityNodeInfo host and info are not nullable!
Ensure that your MenuItem has an actionViewClass associated with it.
<item
...
android:icon="ICON_REFERENCE"
app:showAsAction="ifRoom"
app:actionViewClass="android.widget.ImageButton"
...
/>
Bonus to option 2:
To be able to customize a11y attributes, you can then get the item and assign custom role descriptions or extra actions:
// inside onCreateOptionsMenu
val menuActionView = menu
.findItem(R.id.action_settings)
.actionView as ImageButton
ViewCompat.setAccessibilityDelegate(menuActionView, object: AccessibilityDelegateCompat() {
override fun onInitializeAccessibilityNodeInfo(
host: View?,
info: AccessibilityNodeInfoCompat?
) {
super.onInitializeAccessibilityNodeInfo(host, info)
info?.apply {
// not required as this is already a button
// always use a built in class as this will be localized
// automatically for you
// roleDescription = Button::class.java.simpleName
// I found I had to set this here, and not in the menu xml
contentDescription = getString(R.string.action_settings)
// to replace the term "activate" in "double tap to activate"
// in production apps, use a localized string!
addAction(
AccessibilityNodeInfoCompat.AccessibilityActionCompat(
AccessibilityNodeInfoCompat.ACTION_CLICK, "Open menu"
)
)
}
}
})
When there is any address in string, showing in TextView, need to be clickable and open on maps.
I've tried tv.setAutoLinkMask(Linkify.ALL). It is not working for all addresses.
Any other way that's make clickable and link all addresses in TextView?
you can use simple on click listener.
textView.setOnClickListener {
//open google maps
}
and for text to make it look like a link you can use:
<string name="underline_text"><![CDATA[<u>underlined text</u>]]></string>
Also, you can use blue text color (#0D6EFD) to make it more professional.
you can use Intent.ACTION_VIEW to open google map from your app. Something like this:
tv.setOnClickListener {
val address = tv.text
val content = "geo:0,0?q=$address"
val intent = Intent(Intent.ACTION_VIEW, Uri.parse(content))
startActivity(intent)
}
Here I'm using Kotlin, convert java if you want
I have a problem statement where i need to run my application with Accessibility setting on, to have talk back feedback, but the problem here is when i click on a TextView which have Spannable link in it, then it reads the full text but dose not allow me to click on that Spannable text separately while disabling the accessibility allows to make string multi spannable or link clickable.
here is my code to make String clickable :
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));
}
#Override
public void updateDrawState(TextPaint ds) {
super.updateDrawState(ds);
ds.setUnderlineText(false);
}
};
ss.setSpan(clickableSpan, 22, 27, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
TextView textView = (TextView) findViewById(R.id.hello);
textView.setText(ss);
textView.setMovementMethod(LinkMovementMethod.getInstance());
textView.setHighlightColor(Color.TRANSPARENT);
If you are using Android X library you should be able to handle accessibility and clickable spannable strings by:
ViewCompat.enableAccessibleClickableSpanSupport(yourView);
Also make sure you have the latest dependency:
com.android.support:appcompat-v7:28.0.0
It should work back to API 19.
Note: To enable Android X library go to your gradle.properties and add these lines:
android.useAndroidX = true
android.enableJetifier = true
I'm afraid there is no way in android to implement that (I had the same issue for months). the only way is using the local context menu. Looks like Talkback is trying to make the ADA users to get use to the menus using there gestures, which will fix too many issue in our dev side. There might be another way, which is creating a WebView and then add html elements which will handle everything, BUT this will be bad for the app performance :(
As mentioned here: Clickable links (Google support)
you have to access local context menu to activate any clickable span by Swiping up and then right, and then click on Links submenu.
Hope this helps :)
Try this one, worked for me. An alternate working solution.
private void setUpBottomSheetAccessibility() {
ViewCompat.setAccessibilityDelegate(view, new AccessibilityDelegateCompat() {
#Override
public void onPopulateAccessibilityEvent(View host, AccessibilityEvent event) {
if (event.getEventType() == AccessibilityEvent.TYPE_VIEW_LONG_CLICKED) {
//Put your work to be done on double click;
}
super.onPopulateAccessibilityEvent(host, event);
}
});
}
Above code view is your Textview or any view. And this event work on double click.
Working fine at my end.
Nothing to do.Just you click the Spannable link with two finger on the screen, and one of them must be on the Spannable link. Try some times！！！
I'm trying to implement the share functionality within my app. So far it works fine and I can share text to all other apps. The problem is the way it's shown.
I want something like just the share icon visible and then when user taps on it, it opens the OS dialog and lets user choose the app they want to share content to.
var share_article = menu.FindItem (Resource.Id.action_share);
var share_article_provider = (Android.Support.V7.Widget.ShareActionProvider) Android.Support.V4.View.MenuItemCompat.GetActionProvider (share_article);
share_article_provider.SetShareIntent (CreateIntent ());
and the xml:
<item
android:id="#+id/action_share"
myapp:showAsAction="ifRoom"
android:title="share"
myapp:actionProviderClass="android.support.v7.widget.ShareActionProvider" />
My app currently looks like this:
There's also a white border around it that I don't like.
Is there any way to change the icon??
How do I fix it??
You just want to turn off your share history.There is no official API to do this, but you can make your own ShareActionProvider. Actually there are two similar question on SO:
How do you turn off share history when using ShareActionProvider?
How to hide the share action (which use most) icon near the share action provider?
Wish these could help you.
As mentioned here when using support library this can be fixed really easily. This method won't turn off the share history but will hide the icons from actionbar.
I just needed to subclass the Android.Support.V7.Widget.ShareActionProvider like the following: (C# using Xamarin)
public class MyShareActionProvider : Android.Support.V7.Widget.ShareActionProvider
{
public SingleArticleShareActionProvider (Context context) : base (context)
{}
public override View OnCreateActionView ()
{
return null;
}
}
and then inside OnCreateOptionsMenu use the MyShareActionProvider like:
var share_article = menu.FindItem (Resource.Id.action_share);
var share = new SingleArticleShareActionProvider (globalContext);
Android.Support.V4.View.MenuItemCompat.SetActionProvider (share_article, share);
share_article.SetIcon (Resource.Drawable.abc_ic_menu_share_mtrl_alpha);
share.SetShareIntent (CreateIntent ());
You can use any icon you like with the method SetIcon.
I have the fallowing text: "By clicking OK you will disable the service. Learn more".
i want to make "Learn more" clickable, however i want a popup menu to appear instead of directing to a website
i have used the fallowing stack question :
How to set the part of the text view is clickable
which worked great. i found the index of learn more by ". ". this solution crashes the application in Chinese and Hindi languages (in Hindi a point is written -> |).
How can i make the "Learn more" clickable in a generic way to show a popup menu?
Is there maybe a way to define the click action in strings.xml, like calling a link? (instead of calling a link -> launch popup menu?)
You can use WebView and anchor. Create new WebViewClient (especially you need this method: shouldOverrideUrlLoading()) and do everything you want when user will click your anchor.
You can create a click event based on the text as you defined.. Check this library.. it may help you.. https://github.com/klinker24/Android-TextView-LinkBuilder
solved it, might be a hack but it works fine.
in strings.xml i have added
//<a></a> tags to be removed later on
<string name="learn_more">By clicking OK you will disable the service. <a>Learn more</a></string>
in the code :
TextView textView= (TextView) findViewById(R.id.textViewInLayout);
textView.setMovementMethod(LinkMovementMethod.getInstance());
textView.setText(R.string.learn_more);
//indexes of the clickable text
int start = textView.getText().toString().indexOf("<a>");
int end = textView.getText().toString().indexOf("</a>");
//set the text as html to make the tags disappear
textView.setText(Html.fromHtml(getString(R.string.learn_more)));
//make the text clickable
Spannable spannable = (Spannable) textView.getText();
ClickableSpan myClickableSpan = new ClickableSpan() {
#Override
public void onClick(View widget) {
yourActionHere();
}
};
// end - 3 beacuse of </a>
spannable.setSpan(myClickableSpan, start, end - 3,Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);`
