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:
XML:
To implement the view in your xml layout do the following:
- 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>
-
Add the following code to the root view of your layout:
xmlns:ProgressWheel="http://schemas.android.com/apk/res/com.visualdenim.schooltraq"
-
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.
Add this to your build.gradle:
repositories {
maven { url "https://jitpack.io" }
}
dependencies {
compile 'com.github.Todd-Davies:ProgressWheel:1.2'
}
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.
