推荐答案
如果我理解你正在试图做正确的东西你想看看 ellipsize 和 marqueeRepeatLimit 的TextView 的属性。
If I'm understand what you're trying to do properly you want to look at the ellipsize and marqueeRepeatLimit properties of TextView.
通过API：
<一个href="http://developer.android.com/reference/android/widget/TextView.html#attr_android:ellipsize">http://developer.android.com/reference/android/widget/TextView.html#attr_android:ellipsize
<一个href="http://developer.android.com/reference/android/widget/TextView.html#attr_android:marqueeRepeatLimit">http://developer.android.com/reference/android/widget/TextView.html#attr_android:marqueeRepeatLimit
另外，看看这个问题一个实现。从我记得，当我不得不实施这样的事情是，XML属性可能会非常棘手。他们彼此干扰和prevent来自全国各地的屏幕上滚动的文字，因此可能需要一些与玩弄得到它的权利。
Also, look at this question for an implementation. From what I remember when I had to implement something like this is that the XML properties can be tricky. They interfere with one another and prevent the text from scrolling across the screen so it may take some toying with to get it right.
在这里，有不同的报价填充它很简单，只要调用的setText（）在的TextView 的随机的报价，我认为你必须存储在在适当的时候数组或数据库。
From there, populating it with different quotes is as simple as calling setText() on the TextView with the random quote that I assume you'll have stored in an array or database at the proper time.
