button = b
Imageview img
class MainActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
        b= (Button) findViewById(R.id.button)
        img = (ImageView) findViewById(R.id.imageView)
        b.setOnClickListener(View.OnClickListener {
            @Override
            public void onClick(View v) {
                img.set.ImageResource(R.mipmap.amogus)
            }
