JarCastingAndroidMaterialViews - README
"AndroidMaterialViews" is an Android-library, which provides various views, which are part of Android's Material Design guidelines, but which are not provided by the official Android SDK. The library's views can also be used on pre-Lollipop devices.
The library provides the following views:
- A
CircularProgressBar, which allows to visualize an indeterminate progress as an animated circle. - A
FloatingActionButton, which is a round, colored button with a shadow and an icon. The button supports to become shown or hidden in an animated manner. - A
Chip, which acts like a tag, containing a text and optionally an icon and a close button.

Download
The latest release of this library can be downloaded as a zip archive from the download section of the project's Github page, which is available here. Furthermore, the library's source code is available as a Git repository, which can be cloned using the URL https://github.com/michael-rapp/AndroidMaterialViews.git.
Alternatively, the library can be added to your Android app as a Gradle dependency by adding the following to the respective module's build.gradle file:
dependencies {
compile 'com.github.michael-rapp:android-material-views:3.0.1'
}
Before version 2.0.0 this project was hosted on Sourceforge. These older versions used the legacy Eclipse ADT folder structure and are not available as Gradle artifacts.
Examples
The following examples provide a quick overview on how to use the views, which are provided by the library, in your own Android app. This project also contains the source code of an example app, which implements an use case of the library for demonstration purposes, as well as a more detailed documentation in the Wiki and auto-generated javadoc files.
CircularProgressBar
The XML code below shows how the view CircularProgressBar can be added to a XML layout resource. This example contains all of the view's custom attributes.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<de.mrapp.android.view.CircularProgressBar
android:id="@+id/circular_progress_bar"
android:layout_width="@dimen/circular_progress_bar_size_normal"
android:layout_height="@dimen/circular_progress_bar_size_normal"
android:color="@color/circular_progress_bar_color"
android:thickness="@dimen/circular_progress_bar_thickness_normal" />
</RelativeLayout>
FloatingActionButton
The following example demonstrates how a FloatingActionButton can be declared within a XML layout resource. The example contains all of the view's custom attributes.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:custom="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<de.mrapp.android.view.FloatingActionButton
android:id="@+id/floating_action_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:color="@color/floating_action_button_color"
android:icon="@drawable/floating_action_button_icon"
custom:size="normal"
custom:activatedColor="@color/floating_action_button_activated_color"
custom:pressedColor="@color/floating_action_button_pressed_color"
custom:disabledColor="@color/floating_action_button_disabled_color"
custom:visibilityAnimationDuration="500" />
</RelativeLayout>
Chip
The following XML code shows how a Chip can be added to a XML resource. The example contains a text as well as an icon and a close button. By using a Chip's addCloseListener-method, listeners can be registered to be notified when a chip has been closed.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:custom="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<de.mrapp.android.view.Chip
android:id="@+id/chip"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/chip_text"
android:color="@color/chip_color_"
android:icon="@drawable/chip_icon" />
</RelativeLayout>
If a dark theme should be used by a Chip, this can be achieved by adding a style-tag like shown in the following:
<de.mrapp.android.view.Chip
style="@style/Chip"
