Kotlin Excersing Example

• Creating Class
• Creating dynamic TableLayout
• Global variables
• Creating ArrayList

class MainActivity : AppCompatActivity() {

    lateinit var TR1:TableRow
    lateinit var TR2:TableRow
    lateinit var B1:Button
    lateinit var B2:Button
    lateinit var CommandList:ArrayList<CommandInfo>

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        val TL1 = findViewById(R.id.myTableLayout) as TableLayout;

        TR1 = TableRow(this)
        TR2 = TableRow(this)
        B1 = Button(this)
        B2 = Button(this)

        CommandList = arrayListOf<CommandInfo>()

        B1.setText("Dynamic Button1")
        TR1.addView(B1)
        B2.setText("Dynamic Button2")
        //TR1.addView(B2)
        TR2.addView(B2)
        TL1.addView(TR1)
        TL1.addView(TR2)
        h_ChangeName();
        val CM1 = CommandInfo(999.toString(), 100, ("-1").toInt(), 91)
        CommandList.add(CM1)
        B1.setText(CommandList.get(0).Commandname)

    }

    fun h_ChangeName(){
        B1.setText("Dynamic Button1-1");
    }


}

class CommandInfo(
    val Commandname: String?,
    val CommandNo: Int?,
    val ExecutionTime: Int?,
    val ExecutionPerio: Int?
)
