How to set marquee behaviour in android to alternate programatically

Question

This is the code I am using but the behaviour of the marquee is that is scrolls. How to make it to alternate i.e. it moves from right to left and then left to right.

public void setMarquee(TextView textView) {
        textView.setEllipsize(TextUtils.TruncateAt.MARQUEE);
        textView.setMarqueeRepeatLimit(-1);
        textView.setHorizontallyScrolling(true);
        textView.setSelected(true);
        textView.requestFocus();

    }

Answer 1

Step1

create folder called anim in res directory

step 2

create slide_left.xml

slide_left.xml

    <translate
        android:duration="3000"
        android:fromXDelta="100%"
        android:toXDelta="0" />
</set>

step 3

in main_activity.class

 LinearLayout mlayout =
     (LinearLayout)findViewById(R.id.mlayout); // the view u want to animate
     Animation slide_left_anim;
     slide_left_anim=
    AnimationUtils.loadAnimation(getActivity().getApplicationContext(),
                    R.anim.slide_left);
    slide_left_anim.setRepeatCount(Animation.INFINITE);

     mlayout.startAnimation(slide_left_anim);
