Progress Wheel

This is a custom component for Android intended for use instead of a progress bar.

Compare it side by side with the Android 2x progress wheel:

A complete walkthrough of how to use this component in your app

XML:
To implement the view in your xml layout do the following:

1. Add the following to your attrs.xml file (in res/values):

<declare-styleable name="ProgressWheel">
  <attr name="pwText" format="string" />
  <attr name="pwTextColor" format="color" />
  <attr name="pwTextSize" format="dimension" />
  <attr name="pwBarColor" format="color" />
  <attr name="pwRimColor" format="color" />
  <attr name="pwRimWidth" format="dimension" />
  <attr name="pwSpinSpeed" format="integer" />

 <attr name="pwCircleColor" format="color" />

 <attr name="pwRadius" format="dimension" />
  <attr name="pwBarWidth" format="dimension" />
  <attr name="pwBarLength" format="dimension" />  <attr name="pwDelayMillis" format="dimension"/>  <attr name="pwContourColor" format="color"/>  <attr name="pwContourSize" format="float"/> </declare-styleable> 

2. Add the following code to the root view of your layout: xmlns:ProgressWheel="http://schemas.android.com/apk/res/com.visualdenim.schooltraq"

3. Add the widget code in the appropriate place in your xml file. Here's a sample implementation:

<com.todddavies.components.progressbar.ProgressWheel

  android:id="@+id/pw_spinner"

 android:layout_width="200dp"

android:layout_height="200dp"

  android:layout_centerInParent="true"

  ProgressWheel:pwText="Authenticating..."

ProgressWheel:pwTextColor="#222"

  ProgressWheel:pwTextSize="14sp"

  ProgressWheel:pwRimColor="#330097D6"

  ProgressWheel:pwBarLength="60dp"

ProgressWheel:pwBarColor="#0097D6"

  ProgressWheel:pwBarWidth="5dp"

  ProgressWheel:pwRimWidth="2dp" /> 

Java:
First you need to either get a ProgressWheel from a layout file, or initalise one. Do this by:

• ProgressWheel pw = new ProgressWheel(myContext, myAttributes);
• ProgressWheel pw = (ProgressWheel) findViewById(R.id.pw_spinner);

To spin the progress wheel, you just call . startSpinning() and to stop it spinning, you call .stopSpinning()

Incrementing the progress wheel is slightly more tricky, you call .incrementProgress(). However, this is out of 360,
(because a circle has 360 degrees), and will automatically reset once you get past 360. A percentage display is
automatically displayed.

Using as a dependency

Add this to your build.gradle:

 repositories {

maven {
 url "https://jitpack.io" 
}
  
}

 dependencies {

compile 'com.github.Todd-Davies:ProgressWheel:1.2'  
}

Using as a library project

To use it as a library in Android Studio, please edit build.gradle.

Modify:

apply plugin: 'android' 

Into:

apply plugin: 'android-library' 

Since Android SDK Tools revision 17 (released March 2012), this component can be used as a library project. In this case, you do not need to copy anything into your project's attrs.xml, and you must use the following namespace URI, instead of the above:

xmlns:ProgressWheel="http://schemas.android.com/apk/res-auto"

Otherwise, usage should be the same.
