Seek Bar or Progress Bar or Slide Bar or Slider

This bar will be like this, the name for this bar is seek bar



In the xml file we need to mention like this to call the seek bar

xml

<SeekBar
android:id="@+id/seekbar"
android:layout_width="fill_parent"   
android:layout_height="wrap_content"   
android:layout_margin="10px"  
/>  

The java class file will be like this

Seek.java

package com.android.seek;

import android.app.Activity;
import android.media.AudioManager;
import android.os.Bundle;
import android.widget.SeekBar;
import android.widget.TextView;
import android.widget.SeekBar.OnSeekBarChangeListener;

public class Seek extends Activity {
    /** Called when the activity is first created. */
  AudioManager audioManager;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        final TextView reading = (TextView) findViewById(R.id.reading);
        SeekBar seekBar = (SeekBar)findViewById(R.id.seekbar);
        seekBar.setMax(100);
        seekBar.setOnSeekBarChangeListener(new OnSeekBarChangeListener() {
   
   @Override
   public void onStopTrackingTouch(SeekBar seekBar) {
   }
   
   @Override
   public void onStartTrackingTouch(SeekBar seekBar) {
    // TODO Auto-generated method stub
   }
   
   @Override
   public void onProgressChanged(SeekBar seekBar, int progress,
     boolean fromUser) {
    reading.setText("Processing "+progress+"% ");
   }
  });
        }
}
