问题描述

限时删除!!

我有一个MainActivity持有HomeFragment

HomeFragment具有sort按钮Viewpager,其中包含2个片段

HomeFragment has sort button Viewpager which holds 2 fragments

HomeFragment中单击sort按钮时,必须将值传递给ViewPager Fragmensts

when sort button is clicked in HomeFragment, the value has to be passed to ViewPager Fragmensts

我在google上找到了直接位于MainActivity中的Fragments之间的通讯

I google where I found communication between Fragments which is placed directly in MainActivity

推荐答案

我试图借助stackoverflow自己解决此问题

I tried to solve this by myself with the help of stackoverflow

HomeFragment.kt

    private var sort: Int = 0
    private var sortListener: SortListener? = null


    override fun onActivityCreated(savedInstanceState: Bundle?) {
            super.onActivityCreated(savedInstanceState)
            val childFragment = adapter?.instantiateItem(viewPager, fragmentPosition) as ChildFragment
            setSortListener(childFragment)
        }

    fun userClickinSort(){
sortListener?.onSorted(HomeConstants.SORT_TYPE_NAME)
}
    private fun setSortListener(sortListener: SortListener) {
            this.sortListener = sortListener
        }

注意:此SortListener在ChildFragment中实现了

Note: implemented this SortListener in ChildFragment
