Android Horizontal ProgressBar

아래와 같이 생긴 부분 plus버튼을 누르면 쭉쭉 올라가는 부분입니다.

 

 

class MainActivity : AppCompatActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        val progress = findViewById<ProgressBar>(R.id.progress)
        val plus = findViewById<Button>(R.id.plus)

        var count = 0

        plus.setOnClickListener {
            count += 10
            progress.progress = count
        }
        
    }
}
