public InteractiveVoiceView(android.content.Context context,
                            android.util.AttributeSet attrs)

Method Detail

onSizeChanged

protected void onSizeChanged(int w,
                             int h,
                             int oldw,
                             int oldh)

Overrides:

onSizeChanged in class android.view.View

onDraw

protected void onDraw(android.graphics.Canvas canvas)

Overrides:

onDraw in class android.view.View

animateSoundLevel

public void animateSoundLevel(float soundLevel)

Animates sound by modulating radius of a displayed circle. This animation just performs one raise and fall of the circle (radius).

Parameters:

soundLevel -

animateWaitSpinner

public void animateWaitSpinner()

Start wait spinner animation. ARC_PERIOD_SEC represents the period for the spinner arc to complete one revolution. This animation is continued indefinitely, until the animation stopped - animateNone().

animateNone

public void animateNone()

Stop current, if any, animation and change the button state to normal state.

getCurrentRadius

public final float getCurrentRadius()

Returns current radius of the voice animation circle.

Returns:

current radius for the animated circle.

setCurrentRadius

public final void setCurrentRadius(float radius)

Sets new radius for voice animation and requests for a new drawing.

Parameters:

radius - the new radius for voice animation.

soundlevel2radius

protected float soundlevel2radius(float soundLevel)

Converts the current rms value of sound to radius. This implementation assumes RMS value in the soundLevel and performs linear translation. Override this method for custom implementation.

Parameters:

soundLevel - sound level.

Returns:

radius.
