Android 用ViewFlipper实现跑马灯效果的公告提示

1.代码部分
private void initViewFlipper(final HomepageListModel.Notice notice) {
    for (int i = 0; i < notice.noticeTexts.size(); i++) {
        TextView view = new TextView(mContext);
        ViewFlipper.LayoutParams params = new ViewFlipper.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
        params.gravity = Gravity.LEFT | Gravity.CENTER_VERTICAL;
        view.setLayoutParams(params);
        view.setText(notice.noticeTexts.get(i).text_title);
        view.setTextColor(mContext.getResources().getColor(R.color.text_666));
        view.setTextSize(12);

        final HomepageListModel.NoticeText noticeText = notice.noticeTexts.get(i);
        view.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intent = new Intent(mContext, NoticeDetailsActivity.class);
                intent.putExtra("ad_id", noticeText.click_id);
                mContext.startActivity(intent);
            }
        });
        noticeViewFlipper.addView(view);
    }
    //是否自动开始滚动
    noticeViewFlipper.setAutoStart(true);
    //滚动时间
    noticeViewFlipper.setFlipInterval(2000);
    //开始滚动
    noticeViewFlipper.startFlipping();
    //出入动画
    noticeViewFlipper.setOutAnimation(mContext, R.anim.slide_out_top);
    noticeViewFlipper.setInAnimation(mContext, R.anim.slide_in_bottom);
}

2.Xml部分

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="30dp"
    android:background="#f1f1f1"
    android:gravity="center_vertical"
    android:orientation="horizontal">

    <TextView
        android:id="@+id/homepage_notice_tv"
