I have fragment in MainActivity which display a list of categories, i want to add an option when the user click on the categorie item, A new activity should start (MainActivity2) which contains a fragment which display a list of Articles.
the problem is when i put the method Intent that open an activity i have multiples errors.
Here is my MainActivity2:
package com.mbds.news
import android.content.Intent
import android.os.Bundle
import com.google.android.material.floatingactionbutton.FloatingActionButton
import com.google.android.material.snackbar.Snackbar
import androidx.appcompat.app.AppCompatActivity
import androidx.core.content.ContextCompat
import androidx.fragment.app.Fragment
import com.mbds.news.fragments.ArticlesFragment
import com.mbds.news.fragments.CategoriesFragement
class MainActivity2 : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main2)
changeFragment(ArticlesFragment())
}
}
/**
* Ajouter le fragmet [ComputationFragment] dans l'activité
*/
fun MainActivity2.changeFragment(fragment: Fragment) {
supportFragmentManager.beginTransaction().apply {
//3) on remplace le contenu du container
replace(R.id.fragment_container, fragment)
//4) on ajoute la transaction dans la backstack
addToBackStack(null)
}.commit()
// 5) on commit la transaction
}
Here is where i put my redirection :
class CategoriAdapter(private val dataset: List<Category>) :
RecyclerView.Adapter<CategoriAdapter.ViewHolder>() {
class ViewHolder(val root: View) : RecyclerView.ViewHolder(root) {
fun bind(item:Category ) {
var txtname = root.findViewById<TextView>(R.id.category_name)
val imageView = root.findViewById<ImageView>(R.id.category_image)
imageView.setOnClickListener {
val intent = Intent(this, MainActivity2::class.java)
startActivity(intent)
}
txtname.text = item.name
Glide
.with(root)
.load(item.image)
.centerInside()
.placeholder(R.drawable.placeholder)
.into(imageView);
}
}
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): ViewHolder {
val rootView = LayoutInflater.from(parent.context)
.inflate(R.layout.list_item, parent, false)
return ViewHolder(rootView)
}
override fun onBindViewHolder(holder: ViewHolder, position: Int) {
holder.bind(dataset[position])
}
override fun getItemCount(): Int = dataset.size
}
Here is my logs :
None of the following functions can be called with the arguments supplied:
public constructor Intent(p0: Context!, p1: Class<*>!) defined in android.content.Intent
