Android flow layout

Introduction

Extended linear layout that wrap its content when there is no place in the current line.

Maven Central [Travis-CI] (https://travis-ci.org/ApmeM/android-flowlayout)

Demonstration

Orientation: HORIZONTAL, Gravity: FILL, LayoutDirection: LTR

Orientation: HORIZONTAL, Gravity: RIGHT & BOTTOM, LayoutDirection: RTL

Orientation: VERTICAL, Gravity: CENTER, LayoutDirection: LTR

Debug is switched off:

Installation and usage

Take from maven repository (http://search.maven.org/#search%7Cga%7C1%7Corg.apmem.tools, http://mvnrepository.com/search.html?query=org.apmem.tools) or add FlowLayout and other components to your solution

Add it as dependency in Gradle as:

compile 'org.apmem.tools:layouts:1.10@aar'

Or maven

    <dependency>
        <groupId>org.apmem.tools</groupId>
        <artifactId>layouts</artifactId>
        <version>1.10</version>
        <scope>provided</scope>
    </dependency>

Add the following xml code into your layout/something.xml:

<org.apmem.tools.layouts.FlowLayout
	xmlns:android="http://schemas.android.com/apk/res/android"
	android:layout_width="fill_parent"
	android:layout_height="wrap_content"
>
</org.apmem.tools.layouts.FlowLayout>

To change default direction use the following code

android:orientation="vertical"

To change layout direction use the following code

xmlns:f="http://schemas.android.com/apk/res/your.namespace"
f:layoutDirection="rtl"

Android gravity now supported (in combination with elements weight):

    f:weightDefault="1.0"
    android:gravity="fill"

To override default spacing between elements use default android margins in the child View element:

android:layout_marginTop="32dip"
android:layout_marginRight="32dip"

Also if you need to break line before some object even if there is enough space for it in the previous line - use the following LayoutParameter in the child view element:

f:layout_newLine="true"

Detailed parameters

Layout parameters:

* android:orientation - line direction. Use one of the following values:

	* horizontal - line will be in horizontal direction, linebreak will create new line

	* vertical - line will be in vertical direction, linebreak will create new column

    * android:gravity - standard android gravity supported

* debugDraw - draw debug information

    * weightDefault - default weight value for child elements. Used to fill line in case of Gravity.FILL_HORIZONTAL | Gravity.FILL_VERTICAL

    * layoutDirection - direction of inner child elements:

            *  ltr - left to right direction

            *  rtl - right to left direction

Child layout parameters:

* android:layout_margin* - override default spacings

* android:layout_gravity - standard android gravity supported

    * layout_weight - weight of the element. If not specified "layout.defaultWight" is used.

* layout_newLine - break line before current element even if there is enough place in the current line.
