Marque text not moving if texts are less in android

I am using below code, it's working fine for big statement, but not for small text like only "hello".

<TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:ellipsize="marquee"
            android:marqueeRepeatLimit="marquee_forever"
            android:maxLines="1"
            android:scrollHorizontally="true"
            android:singleLine="true"
            android:text="this_bill_has_some_unipay_points_promotion"/>

You should call TextView.isSelected = true to start the text moving.

Edit: Working solution

<TextView
     android:id="@+id/textView"
     android:layout_width="match_parent"             
     android:layout_height="48dp"
     android:ellipsize="marquee"
     android:gravity="center_vertical"
     android:scrollHorizontally="true"
     android:singleLine="true"
     android:textColor="@android:color/white" />

Extension function

fun TextView.setMovingText(text: String) = this.post {
            val textWidth = this.paint.measureText(text)
            val spaceWidth = this.paint.measureText(" ")
            val requiredAdditionalSpace = ((this.width - textWidth) / spaceWidth).toInt()
            this.text = StringBuilder(text).apply {
                for (i in 0..requiredAdditionalSpace) {
                    append(" ")
                }
            }
            this.isSelected = true
        }

How to use

textView.setMovingText("Hey")

I just wanted to show a working solution. Also you can (should) modify for better performance and check for negative values.

Yes, As per marquee property if the text ware less then the width of the layout then it should not scroll.

If you still want to move it then you can do set manually/static width set of the view and the text will be moving, in layout .xml file you get the idea of width of the text view. still having issue let me know.

Instead of android:layout_width="match_parent" you have to set layout width like (30dp 40dp) because The marquee is enabled when the characters are longer than the View's width.
