listview2.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent" android:layout_height="match_parent">

    <ListView
        android:layout_width="wrap_content"

        android:id="@+id/list1"
        android:divider="#0f0"
        android:dividerHeight="3px"
        android:footerDividersEnabled="false"

MainActivity.java

package xiaocool.net.listviewtest;

import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.widget.ArrayAdapter;
import android.widget.ListView;

public class MainActivity extends ActionBarActivity {

   private ListView list;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.listview2);
        list=(ListView)this.findViewById(R.id.list1);
        //定义一个数组
        String arr[]={"校酷网络1","校酷网络2","校酷网络3","校酷网络4","校酷网络5"};
        //将数组包装成ArrayAdapter
        ArrayAdapter<String> adapter=new ArrayAdapter<String>(this,R.layout.array_item,R.id.textView,arr);
        list.setAdapter(adapter);

    }

}
