如何制作完全透明的状态栏？

Question

I want to make so my status bar is transparent, but also without icons on it. I managed to make it so that bar disappeared, but then it left a line that isn't filled with the background. I want to change that so i can actually see the background without any icons being in the way<\/strong> .

import android.os.Bundle
import android.view.View
import androidx.appcompat.app.AppCompatActivity
import androidx.appcompat.app.AppCompatDelegate

class MainActivity : AppCompatActivity() {

    override fun onWindowFocusChanged(hasFocus: Boolean) {
        super.onWindowFocusChanged(hasFocus)
        if (hasFocus) hideSystemUI()
    }

    private fun hideSystemUI() {SYSTEM_UI_FLAG_IMMERSIVE_STICKY
    window.decorView.systemUiVisibility = 
                (View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY
                or View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                or View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                or View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                or View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
                or View.SYSTEM_UI_FLAG_FULLSCREEN)
    }

    override fun onCreate(savedInstanceState: Bundle?) {

        AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_NO)

        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
    }
}

Set these properties in your theme. Thats all
