so i want to open new activity with floatingActionButton, but it doesn't work. I've checked logcat and it doesn't even execute onclicklistener

here is my code:

MainActivity

class MainActivity : AppCompatActivity() {

private lateinit var binding: ActivityMainBinding

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    binding = ActivityMainBinding.inflate(layoutInflater)
    setContentView(R.layout.activity_main)


    binding.addButton.setOnClickListener {
        addButtonActivity()
        Log.e("works", "da clicked")
    }

}

private fun addButtonActivity() {
    val intent = Intent(this, AddMusicActivity::class.java)
    startActivity(intent)
    Log.e("works", "da clicked")
  }

 } 

AddMusicActivity

class AddMusicActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_add_music)
  }
 }

Manifest

        <meta-data

            android:resource="@array/preloaded_fonts" />
    </application>

</manifest>

CodePudding user response：

Yes, the problem is that you should to set the binding view in the method setContentView instead of the layout id, try this

setContentView(binding.root)
