How to create a ProgressBar programmatically?

Most of the time if you provide an AttributeSet manually you have to use one of Android's. Luckily, they've exposed the attribute set that describes a small progress bar. Use this code:

progressBar = new ProgressBar(activity, null, android.R.attr.progressBarStyleSmall);

Create a layout xml file in res/layout directory with desired progress bar containig all attributes you need:

<?xml version="1.0" encoding="utf-8"?><ProgressBar  xmlns:android="http://schemas.android.com/apk/res/android"  android:layout_width="wrap_content"  android:layout_height="wrap_content" ... />

Next in the Activity class you can create ProgressBar object from that layout:

LayoutInflater inflater = getLayoutInflater();    ProgressBar bar = (ProgressBar ) inflater.inflate(R.layout.small_progress_bar, null);

where R.layout.small_progress_bar links to your layout xml file.

Can you still not use xml file?

Activity.java

  progressBar = (ProgressBar) findViewById(R.id.progressbar); `progressBar.setVisibility(View.VISIBLE);`// To Show ProgressBar  `progressBar.setVisibility(View.INVISIBLE);` //To Hide ProgressBar

Check hereProgressDialog is deprecated.What is the alternate one to use?
