                        bottomOfParent (). withMarginDp ( 16 ),
                        leftOfParent (). withMarginDp ( 16 ),
                        width ( 40 ). toDp (). keepRatio ()
                )

                . expect ( name )
                . toBe (
                        toRightOf ( avatar ). withMarginDp ( 16 ),
                        sameCenterVerticalAs ( avatar ),

                )

                . expect ( subname )
                . toBe (
                        toRightOf ( name ). withMarginDp ( 5 ),
                        sameCenterVerticalAs ( name ),
                        toHaveTextColor ( Color . WHITE )
                )

                . expect ( follow )
                . toBe (
                        rightOfParent (). withMarginDp ( 4 ),
                        bottomOfParent (). withMarginDp ( 12 ),
                        toHaveBackgroundAlpha ( 0f )
                )

                . expect ( message )
                . toBe (
                        aboveOf ( follow ). withMarginDp ( 4 ),

                . expect ( bottomLayout )
                . toBe (
                        atItsOriginalPosition ()
                )

                . expect ( content )
                . toBe (
                        atItsOriginalPosition (),

                )

                . toAnimation ()
                . setDuration ( 1500 )

                . start ();

跟随滚动

使用setPercent应用修改动画的当前步骤

滚动视图示例

 this . expectAnimMove = new ExpectAnim ()
                . expect ( username )
                . toBe (
                        toRightOf ( avatar ). withMarginDp ( 16 ),
                        sameCenterVerticalAs ( avatar ),
                        alpha ( 0.5f )
                )

                . expect ( avatar )
                . toBe (
                        topOfParent (),
                        leftOfParent (). withMarginDp ( 16 ),
                        scale ( 0.5f , 0.5f )
                )
                . expect ( follow )
                . toBe (
                        rightOfParent (). withMarginDp ( 16 ),
                        sameCenterVerticalAs ( avatar )
                )

                . expect ( backbground )
                . toBe (
                        height ( height ). withGravity ( Gravity . LEFT | Gravity . START , Gravity . TOP )
                )

                . toAnimation ();

scrollView . setOnScrollChangeListener ( new NestedScrollView . OnScrollChangeListener () {
    @ Override
    public void onScrollChange ( NestedScrollView v , int scrollX , int scrollY , int oldScrollX , int oldScrollY ) {
        final float percent = ( scrollY * 1f ) / v . getMaxScrollAmount ();

        expectAnimMove . setPercent ( percent );
    }
});

您可以使用ExpectAnim.concat （静态方法）一个接一个地播放动画

 ExpectAnim.concat(
                new ExpectAnim()
                        .expect(image1)
                        .toBe(
                                withCameraDistance(500f),
                                flippedHorizontally()
                        )
                        .toAnimation()
                        .setDuration(1000),
                new ExpectAnim()
                        .expect(image2)
                        .toBe(
                                withCameraDistance(1000f),
                                flippedVertically()
                        )
                        .toAnimation()
                        .setDuration(500)
                )
                .start()

直接申请

使用setNow直接应用转换

 new ExpectAnim ()
                . expect ( view )
                . toBe (
                        outOfScreen ( Gravity . BOTTOM )
                )
                . toAnimation ()
                . setNow ();

重置

使用reset返回到视图的初始状态

 expectAnim . reset ():
