Android文本框，具有类似旋转框的下拉菜单

Question

I am trying to implement a text box that, when the user types something, it asynchronously expands a drop-down menu that contains suggestions, much like how the Google search bar shows predictive search queries. In other words, combining an EditText with a Spinner in the sense that the user types something and it presents a list of selectable options right below it. Does such a class exist in the Android library?
