我希望我的ACTV能够在多行上显示文字，因为下拉项目是很长的字符串。
SingleLine = false不起作用，但我读的正确方法是 textMultiLine 。我试了一下它就崩溃了。谁知道这个？
我可以看为什么有多行可能导致出界异常（通常在尚未显示的情况下尝试到达第2行）但真正的理解是超越我。
<AutoCompleteTextView
android:id="@+id/actvSearchStuff"
style="@style/MyEditText"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="15dp"
android:hint="@string/start_search_stuff"
android:inputType="textMultiLine"
android:drawableLeft="@android:drawable/ic_menu_search"
android:imeOptions="actionDone"/>
如果没有这个，我有一个完美的自动完成功能，有或没有自定义布局来显示下拉列表。
