How do I display map server symbols in legend in Kotlin 200.2

[klebercj]

Below is the function I'm using to create my legend data.  Debugging of the data shows the symbology from the map server is being pulled, but not displayed.  What would I need to do in order to make the symbols display in the legend? 

fun showLegendDialog(view: View) {
    val dialogView = LayoutInflater.from(this).inflate(R.layout.legend_dialog, null)
    val builder = AlertDialog.Builder(this)
        .setTitle("Legend")
        .setView(dialogView)
        .setPositiveButton("Close") { dialog, _ -> dialog.dismiss() }

    val dialog = builder.create()
    dialog.show()

    val legendLayout: LinearLayout = dialogView.findViewById(R.id.legendLayout)
    val mapImageLayer = mapView.map?.operationalLayers?.get(0) as? ArcGISMapImageLayer

    mapImageLayer?.let {
        CoroutineScope(Dispatchers.Main).launch {
            val mapServerNameTextView = TextView(this@MainActivity)
            mapServerNameTextView.text = it.name
            mapServerNameTextView.setTypeface(null, Typeface.BOLD)
            mapServerNameTextView.setTextSize(TypedValue.COMPLEX_UNIT_SP, 20f) 
            legendLayout.addView(mapServerNameTextView)
            
            for (sublayer in it.mapImageSublayers) {
                if (sublayer.isVisible) {
                    val sublayerNameTextView = TextView(this@MainActivity)
                    sublayerNameTextView.text = "   " + sublayer.name 
                    sublayerNameTextView.setTypeface(null, Typeface.BOLD)
                    sublayerNameTextView.setTextSize(TypedValue.COMPLEX_UNIT_SP, 16f) 
                    legendLayout.addView(sublayerNameTextView)

                    val legenddata = sublayer.fetchLegendInfos()
                    for (legendInfo in legenddata.getOrThrow()) {
                        val legendImageView = ImageView(this@MainActivity)
                        val symbol = legendInfo.symbol
                        if (symbol != null) {
                            legendLayout.addView(legendImageView)
                        }
                        val legendName = legendInfo.name
                        if (legendName.isNotEmpty()) {
                            val legendNameTextView = TextView(this@MainActivity)
                            legendNameTextView.text = "      " + legendName
                            legendLayout.addView(legendNameTextView)
                        }
                    }
                }
            }
        }
    }
}

You will need to create a bitmap from your symbol and then pass that to your ImageView. In oder to create a bitmap from your symbol, use one of the Symbol.createSwatch functions.

Thank you I was able to use the Symbol.createSwatch functions to display the symbology of the map server I was using.
