What is ImageView in Android?

ImageView is the necessity in app development. ImageView is the part of the view where we can show our own image, that image-data can come from anywhere like a database, from the server, an API or we can also store it locally.

Android ImageView Example

In this example, we use the image-data from the local storage and it is also known as drawable. It is a directory in your project where we keep all our static images.

  1. The first step is to make or open an Android project.
  2. The second step is to create your new layout file or open an old one.
  3. The third step is to add an image view to your layout.
  4. The fourth step is to link the image view with the image file or image data in your drawable folder.
  5. The fifth step is to give height and width to your ImageView.

Your java-file need not have any changes. After everything in place, this will the result.
