android: how do i use the progress bar?

Question

I am writing a media player and i would like to have a progress bar showing the progress of the song. I found the ProgressBar class, but all i can get on the screen is a circular spinning icon. what im looking for is an actual bar.

How do i change the style of the ProgressBar to be a bar (not a circle) and how would i use it with MediaPlayer?

thanks

Answer 1

set style="?android:attr/progressBarStyleHorizontal"

  <ProgressBar android:id="@+id/progreso"
        style="?android:attr/progressBarStyleHorizontal"

and this is an example with MediaPlayer

package com.playerpgbar;

import android.app.Activity;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.ProgressBar;
import android.widget.TextView;

public class Player extends Activity implements Runnable, OnClickListener{

   private TextView Status;
   private ProgressBar progressBar;
   private Button StartMedia;
   private Button Stop;
   private MediaPlayer mp;      

   @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

       Status = (TextView) findViewById(R.id.Status);
        progressBar = (ProgressBar) findViewById(R.id.progressBar);
        StartMedia = (Button) findViewById(R.id.StartMedia);
        Stop = (Button) findViewById(R.id.Stop);

        StartMedia.setOnClickListener(this);
        Stop.setOnClickListener(this);                
    }        

@Override
public void onClick(View v) {
        if(v.equals(StartMedia)){
            if(mp != null && mp.isPlaying()) return;
            mp = MediaPlayer.create(Player.this, R.raw.exodus_piranha);
            mp.start();               
            Status.setText(R.string.PlayingMedia);         
            progressBar.setVisibility(ProgressBar.VISIBLE);
            progressBar.setProgress(0);
            progressBar.setMax(mp.getDuration());
            new Thread(this).start();
        }

        if(v.equals(Stop) && mp!=null){
            mp.stop();
            mp = null;            
            Status.setText(R.string.Stopped);
            progressBar.setVisibility(ProgressBar.GONE);
        }

}

    @Override
    public void run() {
        int CurrentPosition= 0;
        int total = mp.getDuration();
        while(mp!=null && CurrentPosition<total){
            try {
                Thread.sleep(1000);
                CurrentPosition= mp.getCurrentPosition();
            } catch (InterruptedException e) {
                return;
            } catch (Exception e){
                return;
            }            
            progressBar.setProgress(CurrentPosition);
        }
    }


}
