Java Programming

Hello,

Maybe some body know how to fix this error: No enclosing instance of the type MyMap is accessible in scope. Please, help me. Below is my code:

public class MyMap extends MapView
{ 
    public void MyMap()
    {
    } 
    public MyMap(Context context, AttributeSet attrs, java.util.Map inflateParams)
    {
		super(context, attrs, inflateParams);
    }
}

class Top
{
	Top()
	{
		// Here is error;
		// No enclosing instance of the type MyMap is accessible in scope.
		MapView v=(MapView)MyMap.this.findViewById(R.id.mapview); 
	}
}

MapView have final method. How I understand this method can be called without creating object of MyMap.

public final View findViewById(int id)

How I can resolve this bug?
