android的AutoCompleteTextView

MainActivity的代码：

[java]
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.widget.ArrayAdapter;
import android.widget.AutoCompleteTextView;

public class MainActivity extends Activity {
    final String[] tips=new String[]{"hanhan","hanhan313","hanahn98","hanhan758"};
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        //获取自动提示控件
        AutoCompleteTextView actv=(AutoCompleteTextView)findViewById(R.id.actv);
        ArrayAdapter<String> adapter=new ArrayAdapter<String>(this,android.R.layout.易做图_list_item_1,tips);
        //设置数据适配器
        actv.setAdapter(adapter);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.activity_main, menu);
        return true;
    }
}
activity_main.xml的配置代码：

[html]
<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" >

    <AutoCompleteTextView   www.zzzyk.com
        android:id="@+id/actv"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:textColor="#0000ff"
        />

</RelativeLayout>
