The icon to pulse can be a normal bitmap or a SVG file.

In preview mode PulseView renders incorrectly because the Canvas can`t scale in this mode.

Init

Check out in code init:

final PulseView pulseView = (PulseView) findViewById(R.id.pv);
pulseView.setPulseColor(Color.BLACK);
pulseView.setPulseCount(5);
pulseView.setPulseMeasure(PulseView.PulseMeasure.WIDTH);
pulseView.setIconHeight(200);
pulseView.setIconWidth(200);
pulseView.setIconRes(R.drawable.icon);
pulseView.setPulseAlpha(70);
pulseView.setInterpolator(new LinearInterpolator());
pulseView.setPulseListener(new PulseView.PulseListener(...));

To start or finish pulse you need to call methods:

pulseView.startPulse();
pulseView.finishPulse();

Other methods can be seen within the sample application.

And XML init:

<com.gigamole.library.PulseView
    android:id="@+id/pv"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:pv_icon="@drawable/icon"
