diet-memo 만들기 : 데이터베이스에 쓰기가 안됩니다.

안녕하세요 선생님 .'

너무 잘 보고 있어요. 질문에도 대답해주셔서 넘 감사합니다.^^

질문 : 앱도 정상적으로 작동하는데 Firebase 실시간 데이터베이스에 연동이 안됩니다.(에러 메서지도 안 뜹니다.)

1. MainActivity.kt

   package com.ipari.diet_memo import android.app.DatePickerDialog import androidx.appcompat.app.AppCompatActivity import android.os.Bundle import android.util.Log import android.view.LayoutInflater import android.widget.Button import android.widget.DatePicker import android.widget.EditText import android.widget.ImageView import androidx.appcompat.app.AlertDialog import com.google.firebase.database.ktx.database import com.google.firebase.ktx.Firebase import java.util.* class MainActivity : AppCompatActivity() { override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) setContentView(R.layout.activity_main) val writeButton = findViewById<ImageView>(R.id.writeBtn) writeButton.setOnClickListener { val mDialogView = LayoutInflater.from(this).inflate(R.layout.custom_dialog, null) val mBuilder = AlertDialog.Builder(this) .setView(mDialogView) .setTitle("운동 메모 다이얼로그") val mAlertDialog = mBuilder.show() val DateSelectBtn = mAlertDialog.findViewById<Button>(R.id.dataSelectBtn) var dateText="" DateSelectBtn?.setOnClickListener { val today = GregorianCalendar() val year : Int = today.get(Calendar.YEAR) val month : Int = today.get(Calendar.MONTH) val date : Int = today.get(Calendar.DATE) val dlg = DatePickerDialog(this, object : DatePickerDialog.OnDateSetListener{ override fun onDateSet(view: DatePicker?, year: Int, month: Int, dayOfMonth: Int ) { Log.d("MAIN", "${year}, ${month +1}, ${dayOfMonth}") DateSelectBtn.setText("${year}, ${month +1}, ${dayOfMonth}") dateText = "${year}, ${month +1}, ${dayOfMonth}" } }, year, month, date) dlg.show() } val saveBtn = mAlertDialog.findViewById<Button>(R.id.saveBtn) saveBtn?.setOnClickListener { val healthMemo = mAlertDialog.findViewById<EditText>(R.id.healthMemo)?.text.toString() val database = Firebase.database val myRef = database.getReference("myMemo") val model = DataModel(dateText, healthMemo) myRef .push() .setValue(model) } } } }

2. Gradle file

   plugins { id 'com.android.application' id 'com.google.gms.google-services' id 'kotlin-android' } android { compileSdk 33 defaultConfig { applicationId "com.ipari.diet_memo" minSdk 21 targetSdk 33 versionCode 1 versionName "1.0" testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner" } buildTypes { release { minifyEnabled false proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro' } } compileOptions { sourceCompatibility JavaVersion.VERSION_1_8 targetCompatibility JavaVersion.VERSION_1_8 } kotlinOptions { jvmTarget = '1.8' } } dependencies { implementation 'androidx.core:core-ktx:1.9.0' implementation 'androidx.appcompat:appcompat:1.5.1' implementation 'com.google.android.material:material:1.6.1' implementation 'androidx.constraintlayout:constraintlayout:2.1.4' testImplementation 'junit:junit:4.+' androidTestImplementation 'androidx.test.ext:junit:1.1.3' androidTestImplementation 'androidx.test.espresso:espresso-core:3.4.0' implementation platform('com.google.firebase:firebase-bom:30.4.1') implementation 'com.google.firebase:firebase-analytics-ktx' implementation 'com.google.firebase:firebase-auth-ktx' implementation 'com.google.firebase:firebase-database-ktx' }

3. custom_dialog. xml

   <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical"> <EditText android:id="@+id/healthMemo" android:layout_width="match_parent" android:layout_height="60dp" android:layout_margin="20dp" android:hint="운동메모를 입력해주세요." android:background="@android:color/transparent"/> <LinearLayout android:layout_width="match_parent" android:background="#999999" android:layout_marginLeft="10dp" android:layout_marginRight="10dp" android:layout_height="0.5dp"/> <Button android:id="@+id/dataSelectBtn" android:text = "날짜를 선택해주세요." android:layout_margin="20dp" android:layout_width="match_parent" android:layout_height="60dp"/> <Button android:id="@+id/saveBtn" android:text = "저장하기" android:textColor="@color/black" android:layout_marginLeft="20dp" android:layout_marginRight="20dp" android:layout_width="match_parent" android:layout_height="60dp"/> </LinearLayout>

_____그리고 다른 분들은 코드 올릴 때 텍스트형식이 아닌 일정한 형식으로 올리시던데 어떻게 하는건가요? ㅎㅎ
