android学习笔记五——AutoCompleteTextView

AutocompleteTextview

==>

使用比较容易，只需要为其设置一个Adapter，该Adapter封装其需要预设的文本内容。

如下所示实例：

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:tools="http://schemas.android.com/tools"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:paddingBottom="@dimen/activity_vertical_margin"     android:paddingLeft="@dimen/activity_horizontal_margin"     android:paddingRight="@dimen/activity_horizontal_margin"     android:paddingTop="@dimen/activity_vertical_margin"     tools:context=".IndexActivity" >              <AutoCompleteTextView         android:id="@+id/autoText"         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:completionHint="请选择你喜欢的书籍"         android:dropDownHorizontalOffset="20dp"         android:completionThreshold="1"         />   </RelativeLayout>
