Android CircularReveal 错误：在同一视图上启动另一种类型的动画师后不工作

Question

我有一个带有 RecyclerView 的应用程序，在每个项目中我都使用 onTouch() 实现了滑动到 star/dismiss 行为。我的实现没有问题，我可以处理左右滑动并从 RecyclerView 声明拖动。

每一项都是RevealFrameLayout，上面是content，下面是原始布局和要显示的布局，就像这样：

顶部布局：

下方布局（顶部显示层）：

布局下方（显示前的默认布局）：

在那里我显示了顶部显示层（彩色层）并且一切正常，直到我添加了另一个 ObjectAnimator 来隐藏星形布局（制作 starred/unstarred），当显示第一次工作时，然后另一次滑动将执行隐藏动画，然后第三次，它应该再次显示，它真正启动动画（通过调试 start() 被执行）但它没有显示。隐藏动画师第 4 次工作但没有显示布局。

触发任意动作的方法：

void triggerAction(SwipeAction swipeAction, final Note note, final int position) {
    if (swipeAction.getActionId() == SwipeAction.STAR) {
        if (note.isStarred() && !hidden && !hideAnimating && !justAnimated) {
            starActionLayout.setVisibility(View.VISIBLE);
            archiveActionLayout.setVisibility(View.GONE);
            Animator hideAnim = AnimationUtils.createHideAnimation(revealStar);
            hideAnim.addListener(new AnimatorListenerAdapter() {
                @Override
                public void onAnimationEnd(Animator animation) {
                    revealStar.setVisibility(View.INVISIBLE);
                    hideAnimating = false;
                    hidden = true;
                    note.setStarred(false);
                    MainActivity.notesController.set(position, note);
                    super.onAnimationEnd(animation);
                }
            });
            hideAnim.start();
            revealStar.setVisibility(View.VISIBLE); // DEBUG: Only to make sure the star layout is shown.
            justAnimated = true;
            hideAnimating = true;
            revealAnimating = false;
            revealed = false;
            hidden = false;
        } else if (!note.isStarred() && !revealAnimating && !revealed && !justAnimated) {
            starActionLayout.setVisibility(View.VISIBLE);
            archiveActionLayout.setVisibility(View.GONE);
            final ObjectAnimator revealAnim = (ObjectAnimator) AnimationUtils.createCircularReveal(revealStar, (int) getCenterX(starActionImage), (int) getCenterY(starActionImage), 0, (float) getRadius(starActionLayout));
            revealAnim.addListener(new AnimatorListenerAdapter() {
                @Override
                public void onAnimationEnd(Animator animation) {
                    revealAnimating = false;
                    revealed = true;
                    note.setStarred(true);
                    MainActivity.notesController.set(position, note);
                    super.onAnimationEnd(animation);
                }
            });
            revealAnim.start();
            justAnimated = true;
            revealAnimating = true;
            hideAnimating = false;
            hidden = false;
            revealed = false;
            revealStar.setVisibility(View.VISIBLE);
        }
    } else if (swipeAction.getActionId() == SwipeAction.ARCHIVE) {
        if (!revealAnimating && !revealed) {
            int added = starActionLayout.getWidth();
            starActionLayout.setVisibility(View.GONE);
            archiveActionLayout.setVisibility(View.VISIBLE);
            Animator revealAnim = AnimationUtils.createCircularReveal(revealArchive, (int) getCenterX(archiveActionImage) + added, (int) getCenterY(archiveActionImage), 0, (float) getRadius(archiveActionLayout));
            revealAnim.addListener(new AnimatorListenerAdapter() {
                @Override
                public void onAnimationEnd(Animator animation) {
                    revealAnimating = false;
                    revealed = true;
                    super.onAnimationEnd(animation);
                }
            });
            revealAnim.start();
            revealAnimating = true;
            revealArchive.setVisibility(View.VISIBLE);
        }
    }
}

我的条件没有问题，因为调试显示 reveal animator show 代码在应该执行的时候执行。 AnimationUtils 是一个自定义的 class，它包装了 ViewAnimationUtils.createCircularReveal(params) 和另一个自定义的 ObjectAnimator createHideAnimator()，这也没有问题。

AnimationUtils.java:

package com.skaldebane.util.graphics;

import android.animation.Animator;
import android.animation.ObjectAnimator;
import android.os.Build;
import android.view.View;
import android.view.ViewAnimationUtils;
import android.view.animation.LinearInterpolator;

public class AnimationUtils {

    public static Animator createCircularReveal(View view, int centerX, int centerY, float startRadius, float endRadius) {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) return ViewAnimationUtils.createCircularReveal(view, centerX, centerY, startRadius, endRadius);
        else return io.codetail.animation.ViewAnimationUtils.createCircularReveal(view, centerX, centerY, startRadius, endRadius);
    }

    public static Animator createHideAnimation(View view) {
        ObjectAnimator hideAnim = new ObjectAnimator();
        hideAnim.setPropertyName("alpha");
        hideAnim.setFloatValues(1.0F, 0.0F);
        hideAnim.setDuration(300);
        hideAnim.setInterpolator(new LinearInterpolator());
        hideAnim.setTarget(view);
        return hideAnim;
    }

}

注意：不要让我改用 ItemTouchHelper，因为这不是我的问题的主题，也不能解决问题。

Answer 1

我刚刚弄清楚了问题所在。这很简单，但很难注意到。当我应用隐藏动画器时，它会将 alpha 永久设置为 0，这意味着该视图将永远不会再次出现。我只需要在调用 view.setVisiblity(View.INVISIBLE);.

后直接使用 view.setAlpha(1.0F);
