A Small library allowing you to make a smooth indeterminate progress bar

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.

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'
    // or
    compile 'com.github.castorflex.smoothprogressbar:library-circular:x.x.x'
}

You can find the last stable version on [Gradle Please]

Or you can try the latest snapshots:

repositories {
    maven { url "https://oss.sonatype.org/content/repositories/snapshots/" }
}

dependencies {
    compile 'com.github.castorflex.smoothprogressbar:library:[email protected]'
    compile 'com.github.castorflex.smoothprogressbar:library-circular:[email protected]'
}

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"
    />

<fr.castorflex.android.circularprogressbar.CircularProgressBar
	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:cpb_color="#FFee44"
    app:cpb_colors="@array/mycolors"
    app:cpb_rotation_speed="1.0"
    app:cpb_sweep_speed="1.0"
    app:cpb_stroke_width="4dp"
    app:cpb_min_sweep_angle="10"
    app:cpb_max_sweep_angle="300"
    />

Or use styles:

<style name="AppTheme">
    <item name="spbStyle">@style/GNowProgressBar</item>
    <item name="cpbStyle">@style/CircularThemeProgressBar</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>

<style name="CircularThemeProgressBar" parent="android:Widget.Holo.ProgressBar">
        <item name="cpb_color">@color/cpb_default_color</item>
        <item name="cpb_stroke_width">@dimen/cpb_default_stroke_width</item>
        <item name="cpb_min_sweep_angle">@integer/cpb_default_min_sweep_angle</item>
        <item name="cpb_max_sweep_angle">@integer/cpb_default_max_sweep_angle</item>
        <item name="cpb_sweep_speed">@string/cpb_default_sweep_speed</item>
        <item name="cpb_rotation_speed">@string/cpb_default_rotation_speed</item>
</style>

You can find more styles [in the sample app][Sample Themes]

  • Or instantiate a SmoothProgressDrawable/CircularProgressDrawable and set it to your ProgressBar
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(2f)                 //2 times faster
    .progressiveStartSpeed(2)
    .progressiveStopSpeed(3.4f)
    .reversed(false)
    .mirrorMode(false)
    .progressiveStart(true)
    .progressiveStopEndedListener(mListener) //called when the stop animation is over
    .build());
    
mProgressBar.setIndeterminateDrawable(new CircularProgressDrawable
    .Builder(this)
    .colors(getResources().getIntArray(R.array.gplus_colors))
    .sweepSpeed(1f)
    .strokeWidth(mStrokeWidth)
    .style(CircularProgressDrawable.Style.ROUNDED)
    [ ... ]
    .build();

You can also set many colors for one bar (see G+ app)

  • via xml (use the app:spb_colors attribute with a integer-array reference for that)

  • programmatically (use SmoothProgressDrawable.Builder#colors(int[]) method).
