Question

I have a class that extends View (MyView extends View)

In Activity I have next:

    View view = (View)findViewById(R.id.relative_layout_view);

    //here I have error because of cast
    MyView myView = view;

Why its asked me to add cast ?

P.S: I added cast and app is crashes.

Answer 1

Use this way
Just add in xml like

<YourPackage Name.MyView
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:id="@+id/myview"
android:layout_gravity="center"
>   
</YourPackage Name.MyView>

and after that use in activity as given below

   MyView view = (MyView)findViewById(R.id.relative_layout_view);
