I would like to make a TextView scrolling automatically but I did not succeed (as marquee in html). Could you tell me how?

推荐答案

一个TextView，与ellipsize设置为金字招牌，不会滚动，除非它具有焦点。

A TextView, with ellipsize set to "marquee", will not scroll unless it has the focus.

您是否正在寻找一个选取框不管焦点卷轴？

Are you looking for a marquee the scrolls regardless of the focus?

如果是这样，你可以使用一个TranslateAnimation与LinearInterpolator给它提供一致的滚动的样子。这是我使用并能正常工作。

If so, you could use a TranslateAnimation with a LinearInterpolator to give it that consistent scrolling look. This is what I use and it works fine.

    DisplayMetrics dm = getResources().getDisplayMetrics();

    TranslateAnimation m_ta = new TranslateAnimation(dm.widthPixels, -1 * (dm.widthPixels), 0f, 0f);
    m_ta.setDuration(10000);
    m_ta.setInterpolator(new LinearInterpolator());
    m_ta.setRepeatCount(Animation.INFINITE);

    TextView m_tv = (TextView)findViewById(R.id.tvMarquee);
    m_tv.startAnimation(m_ta);
