Android TextView Justify Text

Question

TextView in Android O offers full justification (new typographic alignment) itself.
You just need to do this:

Kotlin

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
    textView.justificationMode = JUSTIFICATION_MODE_INTER_WORD
}

Java

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
    textView.setJustificationMode(JUSTIFICATION_MODE_INTER_WORD);
}

XML

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:justificationMode="inter_word" />

Default is JUSTIFICATION_MODE_NONE (none in xml).
