android 自动匹配文本 AutoCompleteTextView /MultiAutoCompleteTextView

AutoCompleteTextView：每个文本框只能匹配一次

MultiAutoCompleteTextView：能以分隔符为分割点多次匹配

 

 

 1         //AutoComplete 的 XML示例

 2      <AutoCompleteTextView

 3          android:completionThreshold="3"      //输入数达到3时开始显示提示

 4          android:id="@+id/autoCompleteTextView1"

 5          android:layout_width="match_parent"

 6          android:layout_height="wrap_content"

 7          android:layout_alignParentLeft="true"

 8          android:layout_alignParentTop="true"

 9          android:ems="10"

10          android:hint="请输入关键字" >

11      </AutoCompleteTextView>
