Android SeekBar Tutorial -SeekBar Example

SeekBar: SeekBar is one of the very useful user interface element in Android that allows the selection of integer values using a natural user interface. An example of SeekBar is your device’s brightness control and volume control..

Step 1: Open up Android Studio Project through res -> layout -> activity_main.xml (or) main.xml and add below code or just drag and drop the switch to design XML file.

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity">

    <SeekBar
        android:id="@+id/seekBar"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="20dp"
        android:max="200"
        android:progress="60"
        />

</RelativeLayout>

Step 2:Add below code in MainActivity.java to handle events on seekbar.

package com.bytelogs.example;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.support.v7.widget.ButtonBarLayout;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.SeekBar;
import android.widget.Button;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity {

    SeekBar simpleSeekBar;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        // initiate  views
        SeekBar=(SeekBar)findViewById(R.id.seekBar);
        // perform seek bar change listener event used for getting the progress value
        SeekBar.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(MainActivity.this, "Progress is :" + progressChangedValue,
                        Toast.LENGTH_SHORT).show();
            }
        });

    }

    
}
