send parameter from activity to Fragment kotlin-CodePudding

i´m traying to send parameter to fragment. I´m using Volley Class to get data from my db with mysql. I´m transform my response in jsonObject and create my arguments:

val stringRequest: StringRequest = object : StringRequest(
            Method.POST, EndPoint.URL,
            Response.Listener { response ->
                try {
                    val jsonObject = JSONObject(response)

                    if (jsonObject != null) {
                        val dataJson: JSONObject = jsonObject.getJSONObject("user")
                        val name = dataJson.getString("name")
                        val address = dataJson.getString("address")
                        val email = dataJson.getString("email")
                        val phone = dataJson.getString("phone")
                        val password = dataJson.getString("password")

                        val intent = Intent(this, ProfileActivity::class.java)
                        // set parameter to activity
                        val bundle = Bundle()
                        bundle.putString("name", name)
                        bundle.putString("address", address)
                        bundle.putString("email", email)
                        bundle.putString("phone", phone)
                        bundle.putString("password", password)
                        intent.putExtras(bundle)
                        Toast.makeText(applicationContext, "Logged ok", Toast.LENGTH_SHORT).show()
                        startActivity(intent)


                    }
                }

In my Profile activity i´m receiving my parameters:

name = intent.getStringExtra("name").toString()
address = intent.getStringExtra("address").toString()
userEmail = intent.getStringExtra("email").toString()
phone = intent.getStringExtra("phone").toString()
password = intent.getStringExtra("password").toString()

I/ContentValues: name: david
I/ContentValues: userEmail: [email protected]
I/ContentValues: phone: null
I/ContentValues: pass: 123456

But i´m setting my values in EditText but i can´t show it when execute my app. In my fragment i´m doing:

override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle? ): View? {
        // Inflate the layout for this fragment
        val view =  inflater.inflate(R.layout.fragment_profile, container, false)
        val bundle = this.arguments

        val editUserName = view.findViewById<EditText>(R.id.userName)
        var userAddresEdit = view.findViewById<EditText>(R.id.userAddress)
        var userEmailEdit = view.findViewById<EditText>(R.id.userEmailText)
        var userPhoneEdit = view.findViewById<EditText>(R.id.userPhone)
        var userPasswordEdit = view.findViewById<EditText>(R.id.userPasswordEdit)

        /*  userAddresEdit.setText(userAddressConst.toString())
          userEmailEdit.setText(userEmailConst.toString())
          userPhoneEdit.setText(userPhoneConst.toString())
          userPasswordEdit.setText(passwordConst.toString())*/

        Log.i(TAG, bundle.toString())

        return view
    }

My log show null bundle variable.. Idon´t know i cant pass my data to fragment i´m reading in internet, but i can´t find info for to do this.

I´m using kotlin in all my proyect.

Thanks for readme and sorry for my bad english

Update

profileActivity

ProfileFragment.newInstance(name, address, userEmail, phone, password)

Fargment

companion object {

        @JvmStatic
        fun newInstance(param1:String, param2:String, param3:String, param4:String, param5:String) =
            ProfileFragment().apply {
                arguments = Bundle().apply {
                    name = param1
                }
            }
    }

result

I/ContentValues: name: david
I/ContentValues: userEmail: [email protected]
I/ContentValues: phone: null
I/ContentValues: pass: 123456
I/ContentValues: null

CodePudding user response：

Write code inside your Fragment

companion object {

    @JvmStatic
    fun newInstance(param1: String, param2: String) =
        VideoDetailsFragment().apply {
            arguments = Bundle().apply {

            }
        }
}

then call this from activity like this

TestFragment.newInstance("param value 1","param value 2")

CodePudding user response：

In your profile activity, create another bundle with the data and then when you display the fragment:

ProfileFragment().also { it.arguments = bundle }.show(/*fragment manager*/, /*Tag*/)
