Question

How can I extend ImageView, so that I can use in my code findViewById?
I just got 25 ImageViewand I need after click on one to get some value.
I know that I have to create new class, extends ImageView and add constructors, but when I try to implement as findViewById, I got error:

FATAL EXCEPTION: main

Answer 1

in code you use findViewById the same way you would with a normal ImageView but with a cast to your custom view

MyImageView myImageView = (MyImageView)findViewById(R.id.name);

in xml you need to specify the full path of the class

<com.package.name.MyImageView 
    android:id="@+id/name"
    .... />
