Combine two setcontentview in Kotlin

Question

For the DoaHome.kt i want to put two setcontentview. The first one is setContentView(R.layout.cover_home_doa) for the navigation drawer. The other one is setContentView(binding.root) for the expandable list.

This the code of DoaHome.kt

package com.example.senangumrah

import android.content.Intent
import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle
import android.view.View
import android.widget.ImageView

import kotlinx.android.synthetic.main.cover_home_doa.*
import kotlinx.android.synthetic.main.cover_home_persediaan.*
import kotlinx.android.synthetic.main.layout_side_menu.*

class DoaHome : AppCompatActivity(), View.OnClickListener {

private lateinit var binding: ActivityDoaHomeBinding
private lateinit var listViewAdapter: ExpandableListViewAdapter
private lateinit var chapterList: List<String>
private lateinit var topicList: HashMap<String, List<String>>



override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    binding = ActivityDoaHomeBinding.inflate(layoutInflater)
    setContentView(R.layout.cover_home_doa)
    setContentView(binding.root)
    onSetNavigationDrawerEvents()

    showList()

    listViewAdapter = ExpandableListViewAdapter( context = this, chapterList, topicList)
    binding.eListView.setAdapter(listViewAdapter)

    val btnback : ImageView = findViewById(R.id.buttonback)

    btnback.setOnClickListener {
        finish()
    }


}

    if ( doaDrawerLayout.isDrawerOpen(navigationView)) {

    } else {
        super.onBackPressed()
    }
}

override fun onDestroy() {
    super.onDestroy()
}
}

when i put the two setcontentview...my interface is blank..the content not appear and the navigation drawer also does not function..then after that the application suddenly stop responding.

Answer 1

setContentView sets the one-and-only root view of the Activity, so it only makes sense to call it once. If you want to use separate layout files for your drawer and your other content, you can create a top level layout file that defines the layout in it's entirety, and you can use <include/> elements to include other layout files in this top-level layout.
