Daten von einer Aktivität an ein Fragment in Android senden

Question

Ich habe zwei Klassen. Die erste ist Aktivität, die zweite ist ein Fragment, in dem ich einige EditText . In activity habe ich eine Unterklasse mit async-task und in method doInBackground Ich erhalte ein Ergebnis, das ich in einer Variablen speichere. Wie kann ich diese Variable von der Unterklasse "Meine Aktivität" an dieses Fragment senden?

Answer 1

Kotlin : Daten senden Aktivität zu Fragment-Seite

Schritt 1: Aktivität

class SurveyInfoActivity : AppCompatActivity(){
private lateinit var surveyPageOneFragment: SurveyPageOneFragment
override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    binding = ActivitySurveyInfoBinding.inflate(layoutInflater)
    setContentView(binding.root)
    init()
}
private fun init() {
    context = this
    binding.viewPager.isUserInputEnabled = false
    surveyPageOneFragment = SurveyPageOneFragment.newInstance(false)
}

/**
 * then getting your data any side to put on this method
 * ***/
surveyPageOneFragment.setFetchedActivityToFragOne(firstName,middleName,lastName, getMobileNum, getGender, bDay, bMonth, bYear, getAge, getBloodGroup)}

Schritt 2: Fragment eins

fun setFetchedActivityToFragOne(
    gFirstName: String?,
    gMiddleName : String?,
    gLastName: String?,
    gMobile: String?,
    gGender: String?,
    dd: String?,
    mm: String?,
    yyyy: String?,
    gAge: Int?,
    gBloodGroup: String?
){
    this.gFirstName = gFirstName
    this.gMiddleName = gMiddleName
    this.gLastName = gLastName
    this.gMobile = gMobile
    this.gender = gGender
    this.bDay = dd
    this.bMonth = mm
    this.bYear = yyyy
    this.niceAge = gAge
    this.bloodGroup = gBloodGroup
    Log.d("TAG", "Activity get First name: $gFirstName")
    Log.d("TAG", "Activity get middle name: $gMiddleName")
    Log.d("TAG", "Activity get last name: $gLastName")
    Log.d("TAG", "Activity get mobile: $gMobile")
    Log.d("TAG", "Activity get Gender: $gGender")
    Log.d("TAG", "Activity get birthDay: $dd")
    Log.d("TAG", "Activity get birthMonth: $mm")
    Log.d("TAG", "Activity get birthYear: $yyyy")
    Log.d("TAG", "Activity get age: $gAge")
    Log.d("TAG", "Activity get bloodGroup: $gBloodGroup")

    getActivityFetchData(gFirstName,gMiddleName, gLastName, gMobile, gGender,dd,mm,yyyy,gAge,gBloodGroup)
}

Schritt 3: Daten und Kontrollwert abrufen und Text oder Kontrollkästchen setzen

private fun getActivityFetchData(
    gName: String?,
    gMName: String?,
    gLName: String?,
    gMobile: String?,
    gGender: String?,
    gdd: String?,
    gmm: String?,
    gyyyy: String?,
    gAge: Int?,
    gBloodGroup: String?
){
    binding.edtYourName.setText(gName)
    binding.edtMiddleName.setText(gMName)
    binding.edtLastName.setText(gLName)
    binding.edtPhoneCall.setText(gMobile)

    when (gGender) {
        male -> {
            binding.cbMale.isChecked = true
        }
        female -> {
            binding.cbFemale.isChecked = true
        }
        other -> {
            binding.cbTransgender.isChecked = true
        }
    }

    binding.autoDay.setText(gdd)
    binding.autoMonth.setText(gmm)
    binding.autoYear.setText(gyyyy)
    binding.txtAge.text = gAge.toString()

    when (gBloodGroup) {
        posA -> {
            binding.cbPositiveA.isChecked = true
        }
        posB -> {
            binding.cbPositiveB.isChecked = true
        }
        posAB -> {
            binding.cbPositiveAb.isChecked = true
        }
        posO -> {
            binding.cbPositiveO.isChecked = true
        }
        negA -> {
            binding.cbNegativeA.isChecked = true
        }
        negB -> {
            binding.cbNegativeB.isChecked = true
        }
        negAB -> {
            binding.cbNegativeAb.isChecked = true
        }
        negO -> {
            binding.cbNegativeO.isChecked = true
        }
    }
}

I

public static HashMap<String,ContactsModal> contactItems=new HashMap<String, ContactsModal>();

T

ActivityName.contactItems.put(Number,contactsModal);
