Question

单击后，我想对BottomSheetFragment上的布局更改进行动画处理。我实现了ConstraintSet.applyTo和TransitionManager.beginDelayedTransition，将初始场景更改为最终场景。但是当发生过渡时，似乎动画正在重复。样本输出在底部。

BottomSheetFragment.java

ConstraintSet constraintSet;
boolean isSelected = false;

@BindView(R.id.container_root) ConstraintLayout layoutRoot;
@BindView(R.id.ic_leave_date)  ImageView ivLeaveDate;
@BindView(R.id.ic_date_filed)  ImageView ivDateFiled;

@Override
public void onViewCreated(@NonNull View view, @Nullable Bundle savedInstanceState) {
    super.onViewCreated(view, savedInstanceState);
    LayoutTransition transition = new LayoutTransition();
    transition.setAnimateParentHierarchy(false);
    layoutRoot.setLayoutTransition(transition);
}

@OnClick(R.id.layout1)
public void openLeaveDate(){
    TransitionDrawable bgTransition = (TransitionDrawable) layoutLeaveDate.getBackground();
    TransitionDrawable ivTransition = (TransitionDrawable) ivLeaveDate.getBackground();

    if(isSelected){
        isSelected = false;
        bgTransition.reverseTransition(300);
        ivTransition.resetTransition();
        constraintSet = new ConstraintSet();
        constraintSet.clone(getActivity(), R.layout.bottom_sheet_filter_leave);

        TransitionManager.beginDelayedTransition(layoutRoot);
        constraintSet.applyTo(layoutRoot);
    }else{
        isSelected = true;
        bgTransition.startTransition(300);
        ivTransition.startTransition(300);
        constraintSet = new ConstraintSet();

        constraintSet.clone(getActivity(), R.layout.layout_bottom_date_filed);
        TransitionManager.beginDelayedTransition(layoutRoot);
        constraintSet.applyTo(layoutRoot);
    }
}

是这样的：

更新：

我尝试将此设置应用于其他片段（不是BottomSheetFragment），动画似乎正常工作。也许与BottomSheetFragment有关？

Answer 1

我通过删除OnViewCreated（）上的这些行来解决它：

LayoutTransition transition = new LayoutTransition();
transition.setAnimateParentHierarchy(false);
layoutRoot.setLayoutTransition(transition);

在BottomSheetFragment
