Constructor Detail

ResizeAnimation

public ResizeAnimation(android.view.View view,
                       float collapsed,
                       @Nullable
                       ResizeAnimation.Axis axis)

Constructor.

Parameters:

view - The view on which animation occurs

collapsed - The upper limit of the resize animation

axis - The axis on which animation applies

Method Detail

willChangeBounds

public boolean willChangeBounds()

We need to inform that this animation transform the view boundary.

Overrides:

willChangeBounds in class android.view.animation.Animation

applyTransformation

protected void applyTransformation(float interpolated_time,
                                   android.view.animation.Transformation transformation)

Method called during animation progress.

Overrides:

applyTransformation in class android.view.animation.Animation

Parameters:

interpolated_time - The current 0/1 progress value

transformation - A Transformation instance

resize_view

private void resize_view(float transform)

Resize the view on the right axis with the given unity transform.

Parameters:

transform - A value between o and 1 indicating the animation progress.

expand

public void expand()

Animates to ResizeAnimation.State.EXPANDED.

collapse

public void collapse()

Animates to ResizeAnimation.State.COLLAPSED.

state

public ResizeAnimation.State state()

set_state

public void set_state(ResizeAnimation.State state)

Sets view_ dimensions to the corresponding input state value without animating.

Parameters:

state - The state on which the animation should be driven.

set_expanded

public void set_expanded(int expanded)
