There are various methods to display images in Android, and here are some commonly used ones:

  1. With the ImageView widget, you can use it in the layout file and set its src attribute to the image resource file that you want to display, either through the layout file or by setting the image resource through code.
<ImageView
    android:id="@+id/imageView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/image" />
  1. Setting image resources through code: You can set image resources in code by calling the setImageResource() method of an ImageView.
ImageView imageView = findViewById(R.id.imageView);
imageView.setImageResource(R.drawable.image);
  1. Loading images using the Picasso library: Picasso is a popular image loading library that can load images from the network, resource files, or file system, and automatically handle operations such as scaling and caching.

Firstly, you need to add the Picasso library dependency in the project’s build.gradle file.

implementation 'com.squareup.picasso:picasso:2.71828'

Next, you can use Picasso’s API to load images.

ImageView imageView = findViewById(R.id.imageView);
Picasso.get().load("http://example.com/image.jpg").into(imageView);
  1. Load images using the Glide library: Glide is another popular image loading library, similar to Picasso, that can load images from the network, resource files, or the file system, and it provides a rich set of image processing and caching mechanisms.

Firstly, you need to add the Glide library dependency in the project’s build.gradle file.

implementation 'com.github.bumptech.glide:glide:4.12.0'
annotationProcessor 'com.github.bumptech.glide:compiler:4.12.0'

Then you can use the Glide API to load images.

ImageView imageView = findViewById(R.id.imageView);
Glide.with(this).load("http://example.com/image.jpg").into(imageView);

These are some common methods for displaying images in Android, you can choose the one that best fits your needs.
