progressbar androidAndroid is a popular programming language specifically designed for mobile phones and other touch screen devices. It is open source and implements component based architecture. This technology supports great graphics and is compatible with a wide range of hardware. What’s more it offers multiple layers of security along with optimization for low memory and low power usage. It is easy to customize the Android interface to any resolution. This makes it ideal to use in devices with different screen sizes. It’s the most popular mobile operating system today. In this beginner’s level tutorial we show how to create and work with progress bars using Android.

We assume that you have a working knowledge of the Java programming language. If not, you can take this course on Java essentials for Android to get a jump start.

What is Progress Bar?

At times the user needs to be notified that a certain task is still being done, and they need to wait. The controls which provide the information are usually called progress bars. Android has a class named ProgressBar which is instantiated to create progress bar objects.

Types of Progress Bars

There are two types of progress bars that you can use in your programs.

  1. Indeterminate Progress Bar: This is ideally used when the user either doesn’t know or does not want to display the task status. Here the progress is depicted by a continuously moving symbol which does not specify the amount of progress.
  2. Determinate Progress Bar: This progress bar can be either a horizontal bar or any other other shape. Determinate progress bar shows the quantitative amount of progress.

The default maximum value of the ProgressBar is 100. It is also possible to use the android:max attribute to set the desired maximum value.

In case the amount of work to be done is not known, indeterminate mode should be used. You can achieve this in two ways.

ProgressBar vs  ProgressDialog

Progress Dialog box is quite similar to progress bar. However, it is a dialog box, not a bar; and the user has to wait for the task to complete, and take an action, before they can move on the next task. A Progress bar on the other hand, is a simple bar showing the progress so far. No user interaction is normally required.

How to Create a ProgressBar

You can create a progress bar by including the <ProgressBar> tag in the layout XML file. To set the maximum value of the progress bar you need to include the attribute android:max and assign a desired value to it. The attributes that you can use in the ProgressBar tag are the android:minWidth, android:minHeight and android:progress. The first two attributes are used to assign the desired width and height of the progress bar respectively. The third attribute determines the value by which the progress bar value is incremented.

If you want to show real time progress, the horizontal bar is ideal. The progress can be incremented by calling the following methods –  incrementProgressBy() or setProgress().
