Answer 1

In the onCreate method of your java-code assign the button to a variable, and then set a resource or Bitmap which will be decoded from a file using the BitmapFactory class.

Bitmap bmp = BitmapFactory.decodeFile("path/to/file");
ImageButton button1 = (ImageButton)findViewById(R.id.imageButton1);
button1.setImageBitmap(bmp);

Answer 2

Try like this

  ImageButton img = (ImageButton)findViewById(R.id.imageButton2);
  Bitmap bmp = BitmapFactory.decodeFile(path);
  img.setImageBitmap(bmp);
