android Kotlin：tab長按監聽

Question

我正在為如何在我的選項卡上實現長按而苦苦掙扎。 我嘗試了幾種不同的方法，但似乎都不起作用。

我確信它可能是一些基本的東西，或者我根本不理解 tablayout 和尋呼機的點擊。

我在這里發現了一些問題，但它們並不是指長按。

這是我嘗試過的一些事情。

    main_tab_pager.iterator().forEach {
        view ->
        view.setOnLongClickListener{
            Toast.makeText(applicationContext, "....", Toast.LENGTH_LONG).show()
            true
        }
   main_tabs.setOnLongClickListener { 
        when(main_tabs.selectedTabPosition) {
            0-> Toast.makeText(applicationContext, "tab 0", Toast.LENGTH_LONG).show()
            1-> Toast.makeText(applicationContext, "tab 1", Toast.LENGTH_LONG).show()
            2-> Toast.makeText(applicationContext, "tab 2", Toast.LENGTH_LONG).show()
        }
        true 
    }

    main_tab_pager.setOnLongClickListener {
        when(main_tab_pager.currentItem) {
            0-> Toast.makeText(applicationContext, "tab 0", Toast.LENGTH_LONG).show()
            1-> Toast.makeText(applicationContext, "tab 1", Toast.LENGTH_LONG).show()
            2-> Toast.makeText(applicationContext, "tab 2", Toast.LENGTH_LONG).show()
        }
        true
    }

選項卡/尋呼機設置代碼。

main_tab_pager.adapter = TabAdapter(supportFragmentManager, sections)
    main_tabs.setupWithViewPager(main_tab_pager)

標簽適配器

class TabAdapter(fragmentManager: FragmentManager, private val sections: 
Array<BaseFragment>) : FragmentPagerAdapter(fragmentManager) 
{
    override fun getItem(position: Int): Fragment {
        return sections[position]
    }

    override fun getCount(): Int {
        return sections.size
    }

    override fun getPageTitle(position: Int): CharSequence? {
        return sections[position].title
    }
}

感謝Mike M.

   val tabs = main_tabs.getChildAt(0) as LinearLayout

    for (i in 0 until tabs.childCount) {
        when(i){
            0 -> tabs.getChildAt(0).setOnLongClickListener {
                Toast.makeText(baseContext, "tab 0 ", Toast.LENGTH_LONG).show()
                true
            }
            1 -> tabs.getChildAt(1).setOnLongClickListener {
                Toast.makeText(baseContext, "tab 1", Toast.LENGTH_LONG).show()
                true
            }
            2 -> tabs.getChildAt(2).setOnLongClickListener {
                Toast.makeText(baseContext, "tab 2", Toast.LENGTH_LONG).show()
                true
            }
        }
    }

val tabs = recylerbin_tabLayout.getChildAt(0) as LinearLayout
for (i in 0 until tabs.childCount) {
            tabs.getChildAt(i).setOnLongClickListener {
                true
            }
        }
}
