    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center"
    android:orientation="vertical">

    <com.android.library.flowlayout.FlowLayout
        android:id="@+id/flowLayout"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:paddingTop="20dp"
        app:itemMarginX="10dp"
        app:itemMarginY="5dp">

        <TextView
            android:layout_width="50dp"
            android:layout_height="30dp"
            android:background="#22FF0000"

            android:layout_height="30dp"
            android:background="#22FF0000"
            android:gravity="center"

            android:textSize="20dp"
            android:textStyle="bold" />

        <TextView
            android:layout_width="200dp"
            android:layout_height="30dp"
            android:background="#22FF0000"
            android:gravity="center"
            android:text="3"
            android:textSize="20dp"
            android:textStyle="bold" />

        <TextView

            android:layout_height="30dp"
            android:background="#22FF0000"
            android:gravity="center"
            android:text="4"
            android:textSize="20dp"
            android:textStyle="bold" />

        <TextView
            android:layout_width="40dp"
            android:layout_height="30dp"
            android:background="#22FF0000"
            android:gravity="center"
            android:text="5"

            android:textStyle="bold" />
    </com.android.library.flowlayout.FlowLayout>
</LinearLayout>

3. Convert View from Data

you are also enabled to create view from a data set dynamically

val simulated = mutableListOf<String>().apply {
    for (i in 0 until 30)
        add(UUID.randomUUID().toString())
}
binding.flowLayout.applyViewAdapter({ Button(this) }, simulated) { view, data ->
    view.text = data
    view.setPadding(15, 15, 15, 15)
    val lp = view.layoutParams
    lp.width = ViewGroup.LayoutParams.WRAP_CONTENT
    lp.height = ViewGroup.LayoutParams.WRAP_CONTENT
}
