下面是我在關注 youtube 視頻時包含錯誤的代碼（提供的鏈接）我在使用 packageManager.PERMISSION_GRANTED 時遇到錯誤代碼包含名為“未解決的參考：PERMISSION_GRANTED”的錯誤。請幫助快速解決錯誤
package com.example.machineleaarningapp
import android.content.ActivityNotFoundException
import android.content.Intent
import android.graphics.Camera
import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle
import android.provider.MediaStore
import android.widget.Button
import android.widget.ImageView
import android.widget.TextView
import androidx.activity.result.contract.ActivityResultContracts
import androidx.core.content.ContextCompat
import com.example.machineleaarningapp.databinding.ActivityMainBinding
import org.w3c.dom.Text
import java.security.Permission
class MainActivity : AppCompatActivity() {
private lateinit var binding:ActivityMainBinding
private lateinit var imageView: ImageView
private lateinit var button: Button
private lateinit var tvOutput:TextView
private val GALLERREQUESTCODE=123
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
binding= ActivityMainBinding.inflate(layoutInflater)
val view=binding.root
setContentView(R.layout.activity_main)
setContentView(view)
imageView=binding.imageView
tvOutput=binding.resulttv
button=binding.capture
val buttonLoad=binding.Loadimage
button.setOnClickListener{
if(ContextCompat.checkSelfPermission(this,android.Manifest.permission.CAMERA)==packageManager.PERMISSION_GRANTED){
takePicturePreview.lauch(null)
}
else{
requestPermission.launch(android.Manifest.permission.CAMERA)
}
}
}
}[I was following code on this youtube channel[\]\[1\]][1]
uj5u.com熱心網友回復：
代替：
packageManager.PERMISSION_GRANTED
和：
PackageManager.PERMISSION_GRANTED
IOW，在類名中使用大寫字母，P而不是小寫字母。pPackageManager
