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" >

</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

主窗体

import java.util.ArrayList;

import android.app.Activity;
import android.os.Bundle;

import android.widget.ArrayAdapter;
import android.widget.AutoCompleteTextView;

import android.widget.TextView;

public class AutoCompleteTextViewActivity extends Activity {
    /** Called when the activity is first created. */
TextView tv1;TextView tv11;
AutoCompleteTextView autocompletetextview ;
ArrayList<String> list;

// private String ss;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        autocompletetextview=(AutoCompleteTextView)this.findViewById(R.id.auto);
        list=new ArrayList<String>();
        list.add("cys");
        list.add("生哥");
        list.add("english");

        ArrayAdapter<String> adapter=new ArrayAdapter<String>(this,R.layout.list_item,list);
        autocompletetextview.setAdapter(adapter);

}}
