Marquee text in Android

android:ellipsize="marquee"

This only works when your TextView has the focus.

Lots of answers correctly state that calling textView.setSelected(true) is required. However, if preferred to do so just via XML, one option could be to make use of the Binding Adapters when working with Data Binding.

So, just create a new adapter similar to:

@BindingAdapter("app:autoStartMarquee")
fun setAutoStartMarquee(textView: TextView, autoStartMarquee: Boolean) {
    textView.isSelected = autoStartMarquee
}

Then, you can simply use it in the XML as follows:

...
<TextView
    ...
    android:ellipsize="marquee"
    android:singleLine="true"
    app:autoStartMarquee="@{true}"/>
...

No need to call it from code anymore.

This will be equivalent to "end":

where = TruncateAt.END

This is my xml customTextView Object here you can use simply TextView to replace on Tag.

 <com.wedoapps.crickethisabkitab.utils.view.montserrat.CustomTextView
                android:id="@+id/lblRateUsPlayStore"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_marginTop="@dimen/_10sdp"
                android:layout_marginBottom="@dimen/_10sdp"
                android:layout_marginStart="@dimen/_5sdp"
                android:layout_marginEnd="@dimen/_5sdp"
                android:text="@string/please_rate_us_5_star_on_play_store"
                android:textAllCaps="false"
                android:textColor="@color/green"
                android:textSize="@dimen/_25ssp"
                android:textStyle="bold"
                android:visibility="visible"
                android:linksClickable="true"
                android:autoLink="web|phone"/>

And here is My Java File code. i have set my html text on server just replace your text on textview object. i have put this code is marquee tag with clickable if any links on this textview to open mobile or webBrowser.

CustomTextView lblRateUsPlayStore = findViewById(R.id.lblRateUsPlayStore);
lblRateUsPlayStore.setMovementMethod(LinkMovementMethod.getInstance());
                        lblRateUsPlayStore.setText( Html.fromHtml(documentSnapshot.getString("DisplayText")));
                        TextViewCompat.setAutoSizeTextTypeUniformWithConfiguration(lblRateUsPlayStore, 12, 20, 2, 1);

                        lblRateUsPlayStore.setEllipsize(TextUtils.TruncateAt.MARQUEE);

                        // Set marquee repeat limit (unlimited)
                        lblRateUsPlayStore.setMarqueeRepeatLimit(-1);
                        lblRateUsPlayStore.setHorizontallyScrolling(true);
                        lblRateUsPlayStore.setSelected(true);
                        lblRateUsPlayStore.setLinksClickable(true);
                        lblRateUsPlayStore.setFocusableInTouchMode(true);
                        lblRateUsPlayStore.setFocusable(true);

You can use

android:ellipsize="marquee"

with your textview.

But remember to put focus on the desired textview.

For setting Marquee programatically

TextView textView = (TextView) this.findViewById(R.id.textview_marquee);  
textView.setEllipsize(TruncateAt.MARQUEE);
textView.setMarqueeRepeatLimit(-1);
textView.setText("General Information... general information... General Information");
textView.setSelected(true);
textView.setSingleLine(true);
