Android 如何防止在视图关闭动画功能结束前触摸视图？

我有一个自定义java类，它扩展了FrameLayout，它位于另一个扩展FrameLayout的自定义父视图的顶部

我有以下功能，可以通过动画关闭视图-

private void dismissCard(final View view, int xPos) {
    view.animate()
        .x(xPos)
        .y(0)
        .setInterpolator(new AccelerateInterpolator())
        .setDuration(DURATION)
        .setListener(new Animator.AnimatorListener() {
          @Override
          public void onAnimationStart(Animator animator) {
            setOnTouchListener(null);
          }
          @Override
          public void onAnimationEnd(Animator animator) {
            ViewGroup viewGroup = (ViewGroup) view.getParent();
            if (viewGroup != null) {
              viewGroup.removeView(view);
            }
          }
          @Override
          public void onAnimationCancel(Animator animator) {
          }
          @Override
          public void onAnimationRepeat(Animator animator) {
          }
        });
  }

问题是，我已经覆盖了用于移动视图功能的

onTouch（）

函数，对于每次触摸，我都会获得视图的父视图（这是一个自定义视图），获得视图的所有子视图，并通过确定哪个视图位于顶部。因此，我的问题是，在设置动画时，动画视图仍然是位于顶部的视图，因此可以再次移动它，直到动画消失并且调用

viewGroup.removeView（view）

这是我的

onTouch（）

实现-

@Override
  public boolean onTouch(final View view, MotionEvent motionEvent) {
    TinderStackLayout tinderStackLayout = ((TinderStackLayout) view.getParent());
    TinderCardView topCard = (TinderCardView) tinderStackLayout.getChildAt(tinderStackLayout.getChildCount() - 1);
    if (topCard.equals(view)) {
      switch (motionEvent.getAction()) {
        case MotionEvent.ACTION_DOWN:
          oldX = motionEvent.getX();
          oldY = motionEvent.getY();
          // cancel any current animations
          view.clearAnimation();
          return true;
        case MotionEvent.ACTION_UP:
          if (isCardBeyondLeftBoundary(view)) {
            Log.d("top card dismissed - ", topCard.usernameTextView.getText().toString());
            onCardSwipedListener.send(new TopCardMovedEvent(-(screenWidth)));
            dismissCard(view, -(screenWidth * 2));
          } else if (isCardBeyondRightBoundary(view)) {
            showLawyerContactDetailsFragment(topCard);
            onCardSwipedListener.send(new TopCardMovedEvent(-(screenWidth)));
            resetCard(view);
          } else {
            onCardSwipedListener.send(new TopCardMovedEvent(-(screenWidth)));
            resetCard(view);
          }
          return true;
        case MotionEvent.ACTION_MOVE:
          newX = motionEvent.getX();
          newY = motionEvent.getY();
          dX = newX - oldX;
          dY = newY - oldY;
          float posX = view.getX() + dX;
          onCardSwipedListener.send(new TopCardMovedEvent(-(screenWidth)));
          // Set new position
          view.setX(view.getX() + dX);
          view.setY(view.getY() + dY);
          setCardRotation(view, view.getX());
          updateAlphaOfBadges(posX);
          return true;
        default:
          return super.onTouchEvent(motionEvent);
      }
    }
    return super.onTouchEvent(motionEvent);
  }

我缺少的是在

dismissCard（）

设置动画时阻止触摸功能的方法。我怎样才能实现这样的事情

在要设置动画的类中声明一个布尔变量（isAnimating），并在

onAnimationStart

中将其设置为true，在

onAnimationEnd

中将其设置为false

在您的

onTouch

@Override
  public boolean onTouch(final View view, MotionEvent motionEvent) {
    TinderStackLayout tinderStackLayout = ((TinderStackLayout) view.getParent());
    TinderCardView topCard = (TinderCardView) tinderStackLayout.getChildAt(tinderStackLayout.getChildCount() - 1);
    if (topCard.equals(view)&& !isAnimating) { //access event's only if animation is ended.
      switch (motionEvent.getAction()) {
        case MotionEvent.ACTION_DOWN:
          oldX = motionEvent.getX();
          oldY = motionEvent.getY();
          // cancel any current animations
          view.clearAnimation();
          return true;
        case MotionEvent.ACTION_UP:
          if (isCardBeyondLeftBoundary(view)) {
            Log.d("top card dismissed - ", topCard.usernameTextView.getText().toString());
            onCardSwipedListener.send(new TopCardMovedEvent(-(screenWidth)));
            dismissCard(view, -(screenWidth * 2));
          } else if (isCardBeyondRightBoundary(view)) {
            showLawyerContactDetailsFragment(topCard);
            onCardSwipedListener.send(new TopCardMovedEvent(-(screenWidth)));
            resetCard(view);
          } else {
            onCardSwipedListener.send(new TopCardMovedEvent(-(screenWidth)));
            resetCard(view);
          }
          return true;
        case MotionEvent.ACTION_MOVE:
          newX = motionEvent.getX();
          newY = motionEvent.getY();
          dX = newX - oldX;
          dY = newY - oldY;
          float posX = view.getX() + dX;
          onCardSwipedListener.send(new TopCardMovedEvent(-(screenWidth)));
          // Set new position
          view.setX(view.getX() + dX);
          view.setY(view.getY() + dY);
          setCardRotation(view, view.getX());
          updateAlphaOfBadges(posX);
          return true;
        default:
          return super.onTouchEvent(motionEvent);
      }
    }
    return super.onTouchEvent(motionEvent);
  }

另外，更好的解决方案是在isAnimating为

true

时返回false。在我的应用程序中，我已覆盖父类中的dispatch touch，并且不让任何事件到达父类或其任何子类

override fun dispatchTouchEvent(ev: MotionEvent?): Boolean {
 if (isAnimationOnGoing) {
        return false
 }
 return super.dispatchTouchEvent(ev)
}

---

尝试了这两种解决方案。出于某种原因，当代码输入

onTouch

或

dispatchTouchEvent

时，布尔值始终为false，为什么会发生这种情况？另外，第一种方法和第二种方法有什么不同？您需要调试为什么重置布尔值，因为它对我来说非常有效。第一种方法仅对特定视图限制事件，而第二种方法对视图和视图的所有子视图限制事件@阿隆
