How to navigate from specific selected item RecyclerView Inside the Fragment, to 2 different Activity from same RecyclerView in Kotlin?
How to navigate from specific selested item RecyclerView Inside the Fragment, to 2 different Activity in Kotlin?
i have the basic wireframe layout, who describe my question, because i don't know how to explain with good typing.
so here from the wireframe, i have 1 Activity with TabLayout, which is filled with Fragment and there is a RecyclerView in it. And then I have 2 more different Activities. for now, i've successfully implemented data parsing to "OtherActivity1" from RecyclerView inside the fragment TabLayout on MainActivity.
But now, i need to open "OtherActivity2" from the same RecyclerView on Main Activity, what i mean here is specifically only from "RecyclerView Item4" and without data parsing.
How To Doing That?
Anyone have a tutorial?, because i can't find any tutorials like on youtube for this case.
and this my sample code ( not exactly the same, but describing the same meaning) :
MainActivity.kt
class MainActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
setUpTabs() // Assign TabLayout
} // End - OnCreate
// Start - TabLayout
private fun setUpTabs() {
val adapter = ViewPagerAdapter(supportFragmentManager)
adapter.addFragment(TAB1Fragment(), "TAB1")
adapter.addFragment(TAB2Fragment(), "TAB2")
adapter.addFragment(TAB3Fragment(), "TAB3")
viewPager_tabLayout.adapter = adapter
tabs.setupWithViewPager(viewPager_tabLayout)
} // End - TabLayout
} // End Class
TAB1Fragment.kt
class TAB1Fragment : Fragment() {
lateinit var tab1Adapter: TAB1Adapter // Initialize Adapter
private val sLM = StaggeredGridLayoutManager(2, StaggeredGridLayoutManager.VERTICAL) // Initialize LayoutManager
val addTAB1ModelList: MutableList<TAB1Model> = ArrayList() // Initialize ListModel
override fun onCreateView(
inflater: LayoutInflater, container: ViewGroup?,
savedInstanceState: Bundle?
): View? {
return inflater.inflate(R.layout.fragment_tab1, container, false)
} // End onCreateView
override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
super.onViewCreated(view, savedInstanceState)
initViewTAB1() // Assign ListModel putExtras
actionTAB1() // Assign Action putExtras
} // End - OnViewCreated
// Start - ListModel putExtras
fun initViewTAB1() {
rv_tab1.layoutManager = sLM
rv_tab1.setHasFixedSize(true)
tab1Adapter = TAB1Adapter(requireActivity())
rv_tab1.adapter = tab1Adapter
addTAB1ModelList.add(TAB1Model("RecyclerView Item1", "Desc RecyclerView Item1", R.drawable.cv1))
addTAB1ModelList.add(TAB1Model("RecyclerView Item2", "Desc RecyclerView Item1", R.drawable.cv2))
addTAB1ModelList.add(TAB1Model("RecyclerView Item3", "Desc RecyclerView Item1", R.drawable.cv3))
addTAB1ModelList.add(TAB1Model("RecyclerView Item4", "Desc RecyclerView Item1", R.drawable.cv4))
tab1Adapter.setTAB1(addTAB1ModelList)
}
// End - ListModel putExtras
// Start - Action putExtras
fun actionTAB1() {
tab1Adapter.setOnClickItemListenerTAB1(object : OnItemClickListener {
override fun onItemClick(item: View, position: Int) {
var i = Intent(context, OtherActivity1::class.java)
i.putExtra("prodNameTAB1", tab1Adapter.getTAB1().get(position).getProdNameTAB1())
i.putExtra("prodPriceTAB1", tab1Adapter.getTAB1().get(position).getProdPriceTAB1())

I hope someone help me solve this problem. Thank you so much for taking your time to help me. :)
