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.

  android:id="@+id/pv"
  android:layout_width="match_parent"
