Currently I am a Beginner,

I am using firestore, from where all the Data are showing in RecyclerView like name, address, phone number etc. Now, I want to make phone calls using the "button" besides "phone number ".

In which position do I have to add Call Intent?

    private lateinit var recyclerView: RecyclerView
    private lateinit var userList: ArrayList<User>
    private lateinit var db: FirebaseFirestore
    private lateinit var myAdapter: MyAdapter
    private lateinit var searchView: SearchView

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_newsfeed)

        db = FirebaseFirestore.getInstance()
        recyclerView = findViewById(R.id.userList)
        searchView=findViewById(R.id.searchView)
        recyclerView.layoutManager = LinearLayoutManager(this)
        recyclerView.setHasFixedSize(true)
        userList = arrayListOf()
        myAdapter = MyAdapter(userList)
        recyclerView.adapter = myAdapter
        EventChangeListener()
        searchView.setOnQueryTextListener(object :SearchView.OnQueryTextListener{
            override fun onQueryTextSubmit(query: String?): Boolean {
                return false
            }

            override fun onQueryTextChange(newText: String?): Boolean {
                filterList(newText)
                return true
            }

        })
    }

    private fun filterList(query: String?) {
        if(query!=null){
            val filteredList=ArrayList<User>()
            for (i in userList){
                if(i.city!!.lowercase(Locale.ROOT).contains(query)){
                    filteredList.add(i)
                }
            }
            if(filteredList.isEmpty()){
            }else{
                myAdapter.setFilteredList(filteredList)
            }
        }
    }

    private fun EventChangeListener() {
        db = FirebaseFirestore.getInstance()
        db.collection("users").orderBy("bloodGroup", Query.Direction.ASCENDING)
            .addSnapshotListener(object : com.google.firebase.firestore.EventListener<QuerySnapshot> {
                override fun onEvent(
                    value: QuerySnapshot?,
                    error: FirebaseFirestoreException?
                ) {
                    if (error != null) {
                        Log.e("Firestore Error", error.message.toString())
                        return
                    }
                    for (dc: DocumentChange in value?.documentChanges!!) {
                        if (dc.type == DocumentChange.Type.ADDED) {
                            userList.add(dc.document.toObject(User::class.java))

                        }
                    }
                    myAdapter.notifyDataSetChanged()
                }
            }
            )
    }

MyAdapter code is here:

class MyAdapter(private var userList: ArrayList<User>) :
    RecyclerView.Adapter<MyAdapter.MyViewHolder>() {

    class MyViewHolder(itemView: View) : RecyclerView.ViewHolder(itemView) {
        val name: TextView = itemView.findViewById(R.id.nameTextView)
        val bloodGroup: TextView = itemView.findViewById(R.id.bGTextView)
        val contact: TextView = itemView.findViewById(R.id.cNTextView)
        val cityName: TextView = itemView.findViewById(R.id.addressTextView)

    }
    fun setFilteredList(userList: ArrayList<User>){
        this.userList= userList
        notifyDataSetChanged()
    }


    override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): MyViewHolder {
        val itemView =
            LayoutInflater.from(parent.context).inflate(R.layout.donor_list, parent, false)
        return MyViewHolder(itemView)
    }

    override fun onBindViewHolder(holder: MyViewHolder, position: Int) {
        val user: User = userList[position]

        holder.name.text = user.name
        holder.contact.text = user.contactNumber
        holder.bloodGroup.text = user.bloodGroup
        holder.cityName.text = user.city

    }


    override fun getItemCount(): Int {
        return userList.size
    }

}

How can I make a phone call directly by their given number through tapping an icon, in RecyclerView?

Thank you!

CodePudding user response：

You can do phone calls through Intent here is the demo code

    val phoneIntent = Intent(Intent.ACTION_CALL)
    phoneIntent.data = Uri.parse("tel:1234567890")
    startActivity(phoneIntent)   

add relevant permission to your manifest

<uses-permission android:name="android.permission.CALL_PHONE" /> 

CodePudding user response：

<uses-permission android:name="android.permission.CALL_PHONE" />

I think you are looking for something like this:

Intent intent = new Intent(Intent.ACTION_CALL, Uri.parse("tel:"   "Your Phone_number"));
startActivity(intent);
