new ExpectAnim()
.expect(avatar)
.toBe(
bottomOfParent().withMarginDp(16),
leftOfParent().withMarginDp(16),
width(40).toDp().keepRatio()
)
.expect(name)
.toBe(
toRightOf(avatar).withMarginDp(16),
sameCenterVerticalAs(avatar),
toHaveTextColor(Color.WHITE)
)
.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),
rightOfParent().withMarginDp(4),
toHaveBackgroundAlpha(0f)
)
.expect(bottomLayout)
.toBe(

)
.expect(content)
.toBe(
atItsOriginalPosition(),
visible()
)
.toAnimation()
.setDuration(1500)
.start();
Follow scroll
Use setPercent
to apply modify the current step of the animation
Exemple with a scrollview
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);
}
}
);
Concat
You can play an anim after one other using ExpectAnim.concat
(static method)
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()
Apply directly
Use setNow
to apply directly the transformation
new ExpectAnim()
.expect(view)
.toBe(
outOfScreen(Gravity.BOTTOM)
)
.toAnimation()
.setNow();
Reset
Use reset
to return to the initial state of views
expectAnim.reset():
