Step 3: In your main activity add this code given below
Java
package com.shruti.gfglineprog;Â
import androidx.appcompat.app.AppCompatActivity;Â
import android.graphics.Color;import android.os.Bundle;import android.util.Log;import android.view.View;Â
import com.anton46.stepsview.StepsView;import com.shruti.gfglineprog.databinding.ActivityMainBinding;Â
public class MainActivity extends AppCompatActivity {Â
    ActivityMainBinding binding;Â
    String[] descriptionData={"C","C++","Java","DSA"};Â
    int current_state = 0;Â
    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);Â
        binding=ActivityMainBinding.inflate(getLayoutInflater());        setContentView(binding.getRoot());Â
        StepsView stepsView = binding.spb;        stepsView.setLabels(descriptionData);        stepsView.setBarColorIndicator(Color.BLACK);        stepsView.setProgressColorIndicator(getResources().getColor(R.color.colorAccent));        stepsView.setLabelColorIndicator(getResources().getColor(R.color.colorAccent));        stepsView.setCompletedPosition(0);        stepsView.drawView();Â
        binding.spb.setCompletedPosition(current_state);Â
        binding.btnUp.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                if(current_state<(descriptionData.length-1)){                    current_state=current_state+1;                    binding.spb.setCompletedPosition(current_state).drawView();                }Â
                Log.d("current_state = ",current_state+"");            }        });Â
        binding.btnDown.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                if(current_state>0){                    current_state=current_state-1;                    binding.spb.setCompletedPosition(current_state).drawView();                }            }        });Â
    }} |
Step 4: In your gradle module file add this dependency given below
