lateinit var editText: EditText
lateinit var btnSearch: Button
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
title = "KotlinApp"
editText = findViewById(R.id.editText)
btnSearch = findViewById(R.id.btnSearch)
btnSearch.setOnClickListener {
val intent = Intent(Intent.ACTION_WEB_SEARCH)
val term = editText.text.toString()
intent.putExtra(SearchManager.QUERY, term)
startActivity(intent)
