    app:duration="1000"
    app:hasHole="false"
    app:lineColor="@color/colorPrimary"
    app:lineLength="0.6"
    app:lineLengthChangeable="true"
    app:maxLineLength="0.8"
    app:minLineLength="0.4"
    app:sizeMultiplier="1"
    app:strokeWidth="5dp"/>

Params available in all views:

• duration (int) - duration of one animation cycle in millisecondes
• lineColor (color) - color of the line
• lineLengthChangeable (boolean) - if true, the line length will oscillate between maxLineLength and minLineLength
• lineLength (float) - length of line (in percentage; 1.0 is full length, 0.5 is half of length) if lineLengthChangeable is false
• maxLineLength (float) - max length of line (in percentage; 1.0 is full length, 0.5 is half of length) if lineLengthChangeable is true
• minLineLength (float) - min length of line (in percentage; 1.0 is full length, 0.5 is half of length) if lineLengthChangeable is true
• sizeMultiplier (float) - default size of view will be multiplied with that number
• strokeWidth (dimension) - width of line
• precision (int) - number of points in curve calculated in one cycle
