目录结构

第一步

auto_complete_text.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">
  <AutoCompleteTextView
        android:id="@+id/myAutoCompleteTextView"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content" />
</LinearLayout>

 

 

第二步

MainActivity.java

 

package com.taofu5;

import com.taofu5.R;

import android.app.Activity;
import android.os.Bundle;
import android.widget.ArrayAdapter;
import android.widget.AutoCompleteTextView;

public class MainActivity extends Activity {

    private static final String[] myStr = {"aaa","bbb","ccc","aabb","aad"};
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.auto_complete_text);
        ArrayAdapter<String> aa =
            new ArrayAdapter<String>(this,
                    android.R.layout.simple_dropdown_item_1line,myStr) {
        };
        AutoCompleteTextView textView =
            (AutoCompleteTextView) findViewById(R.id.myAutoCompleteTextView);
        textView.setAdapter(aa);
        textView.setThreshold(1);
    }
}

 

 

第三步

AndroidManifest.xml

 

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="com.taofu5"
      android:versionCode="1"
      android:versionName="1.0">
    <application android:icon="@drawable/icon" android:label="@string/app_name">
        <activity android:name=".MainActivity"
                  android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

    </application>
    <uses-sdk android:minSdkVersion="7" />

</manifest>
