Have a look at the ImageView API  There are several setImage  methods  Which one to use depends on the image you provide  If you have the image as resource  e g  file res drawable my image png   ImageView img   new ImageView this       or  ImageView  findViewById R id myImageView   img setImageResource R drawable my image

Just to go a little bit further in the matter  you can also set a bitmap directly  like this    ImageView imageView   new ImageView this     Bitmap bImage   BitmapFactory decodeResource this getResources    R drawable my image   imageView setImageBitmap bImage     Of course  this technique is only useful if you need to change the image
