Adding an icon to the view
Next, we'll add an icon image to the view.
For now, let's just use a generic icon, such as android_robot.png
. A copy of this can be found on the Internet, and there's a copy included with the files for this chapter. Paste the android_robot.png
file into your project's app/res/drawable/
folder. Don't worry, we'll be using the actual app icons later.
We want to display both the text and an icon together, so we can add the code in order to add the image views to the addContent
method.
In the onCreate
method of MainActivity
, modify the addContent
call to pass the icon as a second parameter:
Drawable icon = getResources() .getDrawable(R.drawable.android_robot, null); overlayView.addContent("Hello Virtual World!", icon);
