How to Name an ImageView
android:id was added in API Level 1This is a unique identifier name for the ImageView, so you can refer to the ImageView later in your project.
1. Add a ImageView in your main.xml file.
2. In the main.xml file, add the code below.
<ImageView
...
android:id = "@+id/myImageView"
/>
3. The "+" character is required if you have not yet defined that id, if perhaps the element you reference is lower in the .xml file.
Otherwise you if it's already defined above (or included) then you can omit the "+" char:
4. Compile and run!
