 ...

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

}

  
}

Layout

 <eu.gsottbauer.equalizerview.EqualizerView

 android:id="@+id/equalizer"

 android:layout_width="match_parent"

 android:layout_height="50dp"

 android:layout_above="@+id/play_button"

 android:layout_margin="30dp"

 app:barColor="@color/colorAccent"

 app:barCount="40"

 app:barAnimationDuration="2000"

 app:barWidth="5dp"

 app:marginLeft="1dp"

 app:marginRight="1dp"

 app:runInBatterySaveMode="true|false"

 />

Attributes

There is some custom attributes you can adjust from the xml:

  • barColor : the equalizer bars color (default is black)
  • barAnimationDuration : (millisecs) the animation follows a pattern and the number of loops is infinite. To set the duration of each loop, use this attribute.
  • barCount : number of the bars
  • barWidth : bar width
  • marginLeft/Right : bar margin
  • runInBatterySaveMode: play animation if battery saver is on

Activity

Initialization + animation

To start animating the equalizer you should add:

EqualizerView equalizer = (EqualizerView) findViewById(R.id.equalizer_view);
 equalizer.animateBars();
 // Whenever you want to tart the animation equalizer.stopBars();
 // When you want equalizer stops animating

And... that's it!, so simple.
