I wrote this Kotlin extension function may can help.

fun String.formatPoint(): String {
    val sb = StringBuilder()
    this.reversed().forEachIndexed { index, c ->
        // 123,123,123
        if ((index + 1) % 3 == 0) {
            if (index != this.length - 1) {
                sb.append("$c,")
            } else {
                sb.append(c)
            }
        } else {
            sb.append(c)
        }
    }

    return sb.toString().reversed()
}

Recommended and preferred way is to do it with the strings.xml file

<string name="format_denominated">%,d</string>

from your Kotlin/Java code

getResources().getString(R.string.format_denominated, value)

Even better with databinding

<TextView
    android:text="@{@string/format_denominated(value)}"
    ............/>
