How to add Seekbar in Android

MainActivity.java

This activity add the code to initiate the seekbar and then perform seekbar changed listener event for getting the changes in the progress of the seekbar. By using this event listener we set get the current value of a seekbar and when a user stop the tracking touch, the value of progress is displayed by using a toast.

package com.example.icowboysradio.myapplication;

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.widget.Button;
import android.widget.SeekBar;
import android.widget.Toast;

public class MainActivitySeekbar extends AppCompatActivity{

    SeekBar simpleSeekBar;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_seekbar);

        simpleSeekBar=(SeekBar)findViewById(R.id.seekBar);

        simpleSeekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
            int progressChangedValue = 0;

            public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
                progressChangedValue = progress;
            }

            public void onStartTrackingTouch(SeekBar seekBar) {
                // TODO Auto-generated method stub
            }

            public void onStopTrackingTouch(SeekBar seekBar) {
                Toast.makeText(MainActivitySeekbar.this, "Seekbar:" + progressChangedValue, Toast.LENGTH_SHORT).show();
            }
        });

    }
}
