Use

Viewmodel In Activity

class MainActivity : BaseActivity<MainViewModel>() {

   override fun onCreate(savedInstanceState: Bundle?) {
       super.onCreate(savedInstanceState)
       setContentView(R.layout.struktur_activity)
       
   
       viewmodel.getdata()
       viewmodel.mData.observe(this, {
           
       })
               
   }

   override fun initViewModel(): MainViewModel {
       return ViewModelProvider(this).get(MainViewModel::class.java)
   }
}

Here is the viewmodel generate from BaseActivity

---

Viewmodel In Fragment

class MainFragment : BaseFragment<MainViewModel>() {
   
   ....	

   override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
       super.onViewCreated(view, savedInstanceState)
       	
       viewmodel.getdata()
       viewmodel.mData.observe(viewLifecycleOwner, {
           
       })
               
   }

   override fun initViewModel(): MainViewModel {
       return ViewModelProvider(this).get(MainViewModel::class.java)
   }
}

Here is the viewmodel generate from BaseFragment

---

Viewmodel In Activity With Toolbar

class MainActivity : BaseToolbarActivity<MainViewModel>() {
   private lateinit var mBinding: ActivityMainBinding

   override fun onCreate(savedInstanceState: Bundle?) {
       super.onCreate(savedInstanceState)
       mBinding = ActivityMainBinding.inflate(layoutInflater)
       setContentView(mBinding.root)
       
   
       viewmodel.getdata()
       viewmodel.mData.observe(this, {
           
       })
               
   }

   override fun setToolbar(): Toolbar {
       return mBinding.appbarLayout.toolbar
   }
   
   override fun initViewModel(): MainViewModel {
       return ViewModelProvider(this).get(MainViewModel::class.java)
   }
}

Here is the viewmodel generate from BaseToolbarActivity and setToolbar generate become to setSupportActionBar

Viewmodel In Fragment With Toolbar

class MainFragment : BaseToolbarFragment<MainViewModel>() {
   
   ....	

   override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
       super.onViewCreated(view, savedInstanceState)
       	
       viewmodel.getdata()
       viewmodel.mData.observe(viewLifecycleOwner, {
           
       })
               
   }
   
   override fun setToolbar(): Toolbar {
       return mBinding.appbarLayout.toolbar
   }

   override fun initViewModel(): MainViewModel {
       return ViewModelProvider(this).get(MainViewModel::class.java)
   }
}

Here is the viewmodel generate from BaseToolbarFragment and setToolbar generate become to setSupportActionBar

Adapter Recyclerview

// Recyclerview Adapter
class MainAdapter : BaseRecyclerViewAdapter<MainAdapter.VHolder, News>() {
   inner class VHolder(itemView: View) : RecyclerView.ViewHolder(itemView) {
       private val mBinding = ItemNewsBinding.bind(itemView)

       init {
           mBinding.root.setOnClickListener {
               onItemClick?.invoke(items[adapterPosition])
           }
       }

       fun onBind(mNews: News) {
           mBinding.textTitleItem.text = mNews.title
           mBinding.textDateItem.text = mNews.timestamp
       }
   }

   override fun onBindViewHolder(holder: VHolder, item: News, position: Int) {
       holder.onBind(item)
   }

   override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): VHolder {
       return VHolder(LayoutInflater.from(parent.context).inflate(R.layout.item_news, parent, false))
   }
}


// in activity
class MainActivity : BaseActivity<NewsVModel>() {

   override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
       super.onViewCreated(view, savedInstanceState)
   
   val mainAdapter = MainAdapter()
   
   newsAdapter.onItemClick = { selected ->
           Toast.makeText(this, selected.title, Toast.LENGTH_SHORT).show()
       }
   
   with(mBinding.rvNews) {
           setHasFixedSize(true)
           adapter = newsAdapter
       }
   }
}
