Question

I want to create a custom dialog box like below

I have tried the foll

Answer 1

Full Screen Custom Alert Dialog Class in Kotlin

1. Create XML file, same as you would an activity

2. Create AlertDialog custom class

   class Your_Class(context:Context) : AlertDialog(context){
   
    init {
     requestWindowFeature(Window.FEATURE_NO_TITLE)
     setCancelable(false)
    }
   
    override fun onCreate(savedInstanceState: Bundle?) {
     super.onCreate(savedInstanceState)
     setContentView(R.layout.your_Layout)
     val window = this.window
     window?.setLayout(WindowManager.LayoutParams.MATCH_PARENT,
                        WindowManager.LayoutParams.MATCH_PARENT)
   
     //continue custom code here
     //call dismiss() to close
    }
   }
   

3. Call the dialog within the activity

   val dialog = Your_Class(this)
   //can set some dialog options here
   dialog.show()
   

Note**: If you do not want your dialog to be full screen, delete the following lines

      val window = this.window
      window?.setLayout(WindowManager.LayoutParams.MATCH_PARENT,
                         WindowManager.LayoutParams.MATCH_PARENT)

Then edit the layout_width & layout_height of your top layout within your XML file to be either wrap_content or a fixed DP value.

I generally do not recommend using fixed DP as you would likely want your app to be adaptable to multiple screen sizes, however if you keep your size values small enough you should be fine
