ConstraintLayout中addView()添加视图未得到预期结果问题求助

代码中的else分支可正常运行，但if分支逻辑存在问题：向ConstraintLayout重新添加视图时，无法得到预期布局效果。
预期实现效果：

实际运行效果不符合需求：

public class ChecklistChildViewHolder extends RecyclerView.ViewHolder {
    CheckBox checkBox;
    ImageView delete, edit, move;
    ConstraintLayout constraintLayout;

    ChecklistChildViewHolder(@NonNull View itemView) {
        super(itemView);
        checkBox = itemView.findViewById(R.id.checkbox_child);
        delete = itemView.findViewById(R.id.delete_child);
        edit = itemView.findViewById(R.id.edit_child);
        move = itemView.findViewById(R.id.move_child);
        constraintLayout = itemView.findViewById(R.id.constraint_child);

    }

    public void updateVisibility(boolean isEnableDelete){

        ConstraintLayout.LayoutParams lpCheckBox = (ConstraintLayout.LayoutParams) checkBox.getLayoutParams();
        ConstraintLayout.LayoutParams lpDelete = (ConstraintLayout.LayoutParams) delete.getLayoutParams();
        ConstraintLayout.LayoutParams lpEdit = (ConstraintLayout.LayoutParams) edit.getLayoutParams();

        if (isEnableDelete) {
            constraintLayout.removeView(move);
            constraintLayout.addView(delete);
            constraintLayout.addView(edit);
            lpDelete.endToEnd = R.id.constraint_child;
            lpDelete.startToEnd = R.id.edit_child;

            lpEdit.startToEnd = R.id.checkbox_child;
            lpEdit.endToStart = R.id.delete_child;

            delete.setLayoutParams(lpDelete);
            edit.setLayoutParams(lpEdit);
        }

        else {
            constraintLayout.removeView(delete);
            constraintLayout.removeView(edit);

            lpCheckBox.endToStart = R.id.move_child;
            lpCheckBox.startToStart = R.id.constraint_child;

            checkBox.setLayoutParams(lpCheckBox);
        }
    }
}

代码存在3个直接导致布局异常的问题，对应修复即可：

• 状态切换不闭环，约束残留：RecyclerView的ViewHolder会被复用，两个分支的状态切换没有做全量重置。切到if分支时，既没有清除上一次else分支给checkBox设置的endToStart = R.id.move_child约束，也没有处理move视图移除后的约束失效问题；切回else分支时，也没有把之前移除的move视图重新加回布局，状态不一致直接导致布局错位。
• 约束修改后未触发重绘：修改LayoutParams的约束属性后，没有主动调用requestLayout()通知布局刷新，新设置的约束不会立即生效。
• 视图添加顺序和依赖顺序冲突：if分支里先add delete再add edit，但delete的约束依赖edit的id，添加delete时edit还没挂载到布局上，会导致约束匹配失败。

修复后的参考代码：

public void updateVisibility(boolean isEnableDelete){
    ConstraintLayout.LayoutParams lpCheckBox = (ConstraintLayout.LayoutParams) checkBox.getLayoutParams();
    ConstraintLayout.LayoutParams lpDelete = (ConstraintLayout.LayoutParams) delete.getLayoutParams();
    ConstraintLayout.LayoutParams lpEdit = (ConstraintLayout.LayoutParams) edit.getLayoutParams();

    if (isEnableDelete) {
        // 移除不需要的move视图
        constraintLayout.removeView(move);
        // 按依赖顺序添加视图：先加被依赖的edit，再加依赖edit的delete
        constraintLayout.addView(edit);
        constraintLayout.addView(delete);

        // 重置checkBox约束，清除残留的move依赖
        lpCheckBox.startToStart = R.id.constraint_child;
        lpCheckBox.endToStart = R.id.edit_child;

        // 设置edit、delete的约束
        lpEdit.startToEnd = R.id.checkbox_child;
        lpEdit.endToStart = R.id.delete_child;
        lpDelete.endToEnd = R.id.constraint_child;
        lpDelete.startToEnd = R.id.edit_child;

        // 应用所有布局参数
        checkBox.setLayoutParams(lpCheckBox);
        edit.setLayoutParams(lpEdit);
        delete.setLayoutParams(lpDelete);

    } else {
        // 移除不需要的edit、delete视图
        constraintLayout.removeView(delete);
        constraintLayout.removeView(edit);
        // 加回move视图
        constraintLayout.addView(move);

        // 重置checkBox约束
        lpCheckBox.startToStart = R.id.constraint_child;
        lpCheckBox.endToStart = R.id.move_child;
        checkBox.setLayoutParams(lpCheckBox);
    }
    // 触发父布局重新计算布局
    constraintLayout.requestLayout();
}

优化建议：不需要反复add/remove视图，直接调用setVisibility()控制delete/edit/move的显示隐藏，再对应切换约束即可，性能更好，也不会出现视图添加顺序导致的约束匹配问题。
