To add image assets in Android, you can follow these steps:

  1. Place the image resource files in the appropriate subfolders within the “res” folder of the project. Depending on the different uses of the images, they can be placed in different folders, such as putting the app icon in the “res/drawable” folder, and putting the interface background image in either the “res/drawable” or “res/drawable-xxx” folder (where “xxx” represents a specific screen density).
  2. Use the ImageView widget in the layout file to display an image. You can add the ImageView widget in the XML layout file and specify the image to display by setting its src attribute. For example:
<ImageView
    android:id="@+id/imageView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/my_image" />

Here, “@drawable/my_image” represents the path to the image resource to be displayed. You can replace it with the specific name of the image resource as needed.

  1. In Java code, to get and set image resources, use the findViewById method to access an instance of an ImageView and then call the setImageResource method to set the image to be displayed. For example:
ImageView imageView = findViewById(R.id.imageView);
imageView.setImageResource(R.drawable.my_image);

Here, “R.drawable.my_image” represents the ID of the image resource to be displayed, which can be replaced with a specific image resource ID as needed.

By following the steps above, you can add image assets in Android and display them.
