How to create a ProgressBar programmatically?

Question

My application needs to create a small ProgressBar programmatically. ProgressBar doesn't have a method to set the style (I want a small ProgressBar). The constructor can take an AttributeSet, however, it is an interface and requires me to implement a set of functions. Is there a way to set the ProgressBar to a small style? (I can't use XML to create ProgressBar.)

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);

This makes the progressbar look yelowish and old instead of the thin blue (newish) one. – AlikElzin-kilaka Jul 22 '13 at 17:30

@kilaka just for future reference, change the android.R.attr.progressBarStyleSmall to android.R.attr.progressBarStyleHorizontal for the newish one :) – ElaGorilaki May 03 '14 at 16:11

@Neil Traft I tried this code, but didn't work. So, Shall I call anything else to show it? – Abdulhamid Dhaiban Aug 22 '16 at 08:41

@AbdulhamidDhaiban You have to add your `ProgressBar` to a `ViewGroup` like `LinearLayout`, then only it will appear on the screen. – CopsOnRoad Mar 14 '18 at 10:10

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?

Instead of inflating manually, you can setYour contentview to this progressbar and change the layout once your data are loded. — amalBit, Apr 08 '14 at 12:23

Activity.java

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

Check here ProgressDialog is deprecated.What is the alternate one to use?

Not sure, but does the progressBar run always in background(just hidden from the UI) after making it invisible? – Shambhu May 15 '18 at 06:45
@Shambhu hi,,,yes it will be run in background...but if you make **View.GONE** it will not run in background as well foreground because object is removed...i hope this may help you – Gowthaman M May 15 '18 at 07:54
