TextView Marquee not working [duplicate]

Answer 1

I have created a custom class AlwaysMarqueTextView

public class AlwaysMarqueeTextView extends TextView
{
    protected boolean a;

    public AlwaysMarqueeTextView(Context context)
    {
        super(context);
        a = false;
    }

    public AlwaysMarqueeTextView(Context context, AttributeSet attributeset)
    {
        super(context, attributeset);
        a = false;
    }

    public AlwaysMarqueeTextView(Context context, AttributeSet attributeset, int i)
    {
        super(context, attributeset, i);
        a = false;
    }

    public boolean isFocused()
    {
        return a || super.isFocused();
    }

    public void setAlwaysMarquee(boolean flag)
    {
        setSelected(flag);
        setSingleLine(flag);
        if(flag)
        setEllipsize(TruncateAt.MARQUEE);
        a = flag;
    }

    @Override
    protected void onFocusChanged(boolean focused, int direction, Rect previouslyFocusedRect) 
    {
        if(focused)

            super.onFocusChanged(focused, direction, previouslyFocusedRect);
    }

    @Override
    public void onWindowFocusChanged(boolean focused)
    {
        if(focused)
            super.onWindowFocusChanged(focused);
    }
}

And you can startMarquee when desire.. like

//textView.setSelected(true); No need of Selection..
textview.setAlwaysMarquee(true); 

Answer 2

These attributes must be included in the textview tag in order to allow scrolling.

Everything else is optional.

android:focusable="true"
android:focusableInTouchMode="true"
android:layout_width="fill_parent"
android:ellipsize="marquee"
