Android SeekBar

Whenever the progress bar of SeekBar is moved, it will call the inbuild method of OnProgressChange(), inside which we can write our functionality

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnFocusChangeListener;
import android.widget.EditText;
import android.widget.SeekBar;
import android.widget.SeekBar.OnSeekBarChangeListener;

public class SeekBarDemo extends Activity implements OnSeekBarChangeListener, OnFocusChangeListener {
 
 SeekBar seekBar;
 EditText editText;

 @Override
 public void onCreate(Bundle savedInstance) {
  super.onCreate(savedInstance);

  <-- get seekBar and editTexts from xml -->

  // Set onClick Listeners
  seekBar.setOnSeekBarChangeListener(this);
  editText.setOnFocusChangeListener(this);

  // Initial setup
  editText.setText("2000.00");
  this.onFocusChange(editText, false);
 }

 // Whenever progress of seekbar is changed, this method will be called
 @Override
 public void onProgressChange(SeekBar seekBar, int progress, boolean fromUser) {
  if(fromUser) {
   int fieldValue = progress * 1000;
   editText.setText(String.format("%d", fieldValue));
  }
 }

 // This method wil be called once mouse is pressed on progress of seekbar 
 @Override 
 public void onStartTrackingTouch(SeekBar seekBar) {
  // TODO Auto-generated method stub (This method is defined in OnSeekBarChangeListener)
 }

 // This method wil be called once mouse is released from progress of seekbar
 @Override
 public void onStopTrackingTouch(SeekBar seekBar) {
  // TODO Auto-generated method stub (This method is defined in OnSeekBarChangeListener)
 }

 // Whenever EditText field is clicked, this method will be called
 @Override
 public void onFocusChange(View v, boolean hasFocus) {
  if(!hasFocus) {
   Double fieldValue = Double.valueOf(((EditText) v).getText().toString());
   int progress = (int) (fieldValue / 1000);
   seekBar.setProgress(progress);
  }
 } 
}
