AutoCompleteTextViewActivity自动完成文本框

xml文件

·1..main.xml

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_width="fill_parent"

    android:layout_height="fill_parent"

    android:orientation="vertical" >

  <AutoCompleteTextView

      android:id="@+id/auto"

      android:layout_width="fill_parent"

    android:layout_height="wrap_content"

     android:layout_marginLeft="10dp"

    />

</LinearLayout>

2.在res下layout下新建一个list_item的xml文件注：是Textview

<?xml version="1.0" encoding="utf-8"?>

<TextView xmlns:android="http://schemas.android.com/apk/res/android"

      android:id="@+id/tv11"

      android:layout_width="fill_parent"

    android:layout_height="fill_parent"

      android:padding="10dp"

      android:textSize="16sp"

      android:textColor="#000" >

</TextView>

 注：不能输入中文，可以长按输入框改输入法便可以
