How to design a progress bar which starts filling from bottom to top direction in android application.

In this tutorial we are creating a vertical progress bar with the use of  android:rotation=”270″ attribute. This attribute allows us to rotate any widget view into degree formation so by default our horizontal progress bar is set as 0 degree and after this attribute on horizontal progress bar it will rotate the progress bar into 270 degree format so it will look like vertical progress bar. So here is the complete step by step tutorial for Create vertical progress bar in android example tutorial.

 package com.verticalprogressbar_android_examples.com;

import android.app.Activity;
import android.graphics.Color;
import android.os.Bundle;
import android.os.Handler;
import android.widget.ProgressBar;
import android.graphics.PorterDuff;


public class MainActivity extends Activity {

 ProgressBar VerticalProgressBar;
 int intValue = 0;
 Handler handler = new Handler();
 
 @Override
 protected void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 setContentView(R.layout.activity_main);
 
 VerticalProgressBar = (ProgressBar)findViewById(R.id.progressBar1);
 
 // Adding colors on progress bar 
 VerticalProgressBar.getProgressDrawable().setColorFilter(Color.CYAN, PorterDuff.Mode.SRC_IN);
 
 
 new Thread(new Runnable() {
 
 @Override

 // TODO Auto-generated method stub
 while(intValue < 100)
 {
 intValue++;
 
 handler.post(new Runnable() {
 
 @Override
 public void run() {
 
 VerticalProgressBar.setProgress(intValue);

 }
 });try {
 Thread.sleep(300);
 } catch (InterruptedException e) {
 e.printStackTrace();
 }
 }
 }
 }).start();
