How to create SeekBar with SeekBar Control with setOnSeekBarChangeListener

Step-01: Make Seek Bar according to the MainActivity.xml

<LinearLayout android:padding="15dp" android:orientation="vertical" android:gravity="center" android:layout_width="wrap_content" android:layout_height="wrap_content"> <SeekBar android:layout_gravity="center_horizontal" android:id="@+id/SeekBarID" android:layout_width="250dp" android:layout_height="wrap_content" android:max="20" android:thumbTint="@color/colorPrimaryDark" /> <TextView android:id="@+id/TextViewID" android:layout_marginTop="20dp" android:layout_width="wrap_content" android:layout_height="wrap_content" android:textSize="20sp" android:textStyle="bold" /> </LinearLayout>

Step-02: Make Seek Bar according to the MainActivity.JAVA

public class MainActivity extends AppCompatActivity { private SeekBar seekBar; private TextView textView; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); seekBar= (SeekBar) findViewById(R.id.SeekBarID); textView = (TextView) findViewById(R.id.TextViewID); textView.setText("Volume: "+seekBar.getProgress()+"/"+seekBar.getMax() ); seekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() { @Override public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) { textView.setText("Volume: "+progress+"/"+seekBar.getMax() ); } @Override public void onStartTrackingTouch(SeekBar seekBar) { Toast.makeText(getApplicationContext(),"onStartTrackingTouch", Toast.LENGTH_LONG).show(); } @Override public void onStopTrackingTouch(SeekBar seekBar) { Toast.makeText(getApplicationContext(),"onStopTrackingTouch", Toast.LENGTH_LONG).show(); } }); } }
