FlowLayout for Android

This is a FlowLayout implementation for Android.

Important notice!

I once needed it. Now its job done long ago.

It works. But it lacks some features, it's not on jcenter or maven central, and design of the library can be better overall.

It is not maintained.

Features

Four flow directions (similar to WinForms). They are:

• leftToRight
• rightToLeft
• topDown
• bottomUp

You can also optionally specify gravity for layout. Center and fill are supported.

Layout child can force starting a new line if layout_breakLine attribute set to true.

To limit max number of lines use maxLines attribute. Default is 0.

Usage example

<?xml version="1.0" encoding="utf-8"?>
<org.deejdev.android.FlowLayout xmlns:android="http://schemas.android.com/apk/res/android"
                                xmlns:app="http://schemas.android.com/apk/res-auto"
                                app:flowDirection="leftToRight"
                                app:elementSpacing="4dp"
                                app:lineSpacing="16dp"
                                android:maxLines="50"
                                android:gravity="center"
                                android:layout_width="fill_parent"
                                android:layout_height="fill_parent">

    <Button
        android:text="button1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"/>

    <Button
        android:text="button2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"/>

    <Button
        android:text="button3"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"/>

    <Button
        android:text="button4"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"/>

    <Button
        android:text="button5"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"/>

    <Button
        app:layout_breakLine="true"
        android:text="button6"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"/>
</org.deejdev.android.FlowLayout>

This results in the following:

Same with gravity set fo fill and without gravity respectively:
