##Description
Small library allowing you to make a smooth indeterminate progress bar. You can either user your progress bars and set this drawable or use directly the SmoothProgressBarView.
Sample app available on the Play Store
##How does it work
I made a blog post about that.
##Integration
The lib is now on Maven Central. All you have to do is add it on your gradle build:
dependencies {
// of course, do not write x.x.x but the version number
compile 'com.github.castorflex.smoothprogressbar:library:x.x.x'
}You can find the last version on Gradle Please
If you really want (or have) to use Eclipse, please look at the forks.
##Usage
- Use directly SmoothProgressBar:
<fr.castorflex.android.smoothprogressbar.SmoothProgressBar
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:indeterminate="true"
app:spb_sections_count="4"
app:spb_color="#FF0000"
app:spb_speed="2.0"
app:spb_stroke_width="4dp"
app:spb_stroke_separator_length="4dp"
app:spb_reversed="false"
app:spb_mirror_mode="false"
app:spb_progressiveStart_activated="true"
app:spb_progressiveStart_speed="1.5"
app:spb_progressiveStop_speed="3.4"
/>Or use styles:
<style name="AppTheme">
<item name="spbStyle">@style/GNowProgressBar</item>
</style>
<style name="GNowProgressBar" parent="SmoothProgressBar">
<item name="spb_stroke_separator_length">0dp</item>
<item name="spb_sections_count">2</item>
<item name="spb_speed">1.7</item>
<item name="spb_progressiveStart_speed">2</item>
<item name="spb_progressiveStop_speed">3.4</item>
<item name="spb_interpolator">spb_interpolator_acceleratedecelerate</item>
<item name="spb_mirror_mode">true</item>
<item name="spb_reversed">true</item>
<item name="spb_colors">@array/gplus_colors</item>
<item name="spb_progressiveStart_activated">true</item>
</style>You can find more styles in the sample app
- Or instantiate a
SmoothProgressDrawableand set it to your ProgressBar (do not forget to set the Horizontal Style)
mProgressBar.setIndeterminateDrawable(new SmoothProgressDrawable.Builder(context)
.color(0xff0000)
.interpolator(new DecelerateInterpolator())
.sectionsCount(4)
.separatorLength(8) //You should use Resources#getDimensionPixelSize
.strokeWidth(8f) //You should use Resources#getDimension
.speed(2.0) //2 times faster
.progressiveStartSpeed(2)
.progressiveStopSpeed(3.4)
.reversed(false)
.mirrorMode(false)
.progressiveStart(true)
.progressiveStopEndedListener(mListener) //called when the stop animation is over
.build());You can also set many colors for one bar (see G+ app)
-
via xml (use the
app:spb_colorsattribute with ainteger-arrayreference for that) -
programmatically (use
SmoothProgressDrawable.Builder#colors(int[])method).
