how to extend TextView with new function

Question

i have the following code, and the problem, that my function rlposition() isn't available from outside the class.

public class RLbadge extends TextView {

    public RLbadge(Context context) {
        super(context);
        this.setTypeface(null, Typeface.BOLD);
        this.setTextColor(Color.WHITE);
        this.setBackgroundResource(R.drawable.badge);
        this.setTextSize(18);
    }

    public void rlposition(Button pButton) {
        // THIS FUNCTION ISNT SEEN FROM OUTSIDE WHY?
    }

    protected void onDraw (Canvas canvas) {
        super.onDraw(canvas);
    }
}

Why is the function rlposition not visible from outside of the class? Isn't it possible to add functionality to an extended TextView?

How do you try to access the method? Show us the code please. — rasmeta, Apr 20 '15 at 12:15

i now answered the question for myself and put it here maybe somebody needs the answer in the future.

The problem was this line of calling:

TextView badgeInfoscan = new RLbadge(this);
badgeInfoscan.rlposition(); // here the error comes

changed to

RLbadge badgeInfoscan = new RLbadge(this);
badgeInfoscan.rlposition(); // the function is visible

 <YOURPACKAGENAME.MyTextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textSize="32sp"
        android:text="TEASTING" />

Here is Class

    public class MyTextView extends TextView {

    public MyTextView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        init(attrs);
    }

    public MyTextView(Context context, AttributeSet attrs) {
        super(context, attrs);
        init(attrs);

    }

    public MyTextView(Context context) {
        super(context);
        init(null);
    }

    private void init(AttributeSet attrs) {
        // Do your staff
        }
    }

}
