先定义一张圆角的图片shape_bg_listview.xml 

Xml代码
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape
="rectangle"
>
<gradient
android:startColor="@android:color/white"
android:endColor
="#FFCCCCCC"
android:angle
="180"
/>
<stroke android:width="0px"
android:color
="@android:color/white"
/>
<solid android:color="@android:color/white"
/>
<corners
android:bottomRightRadius="20px"
android:bottomLeftRadius
="20px"
android:topLeftRadius
="20px"
android:topRightRadius
="20px"
/>
</shape>
然后在ListView中引用它,注意android:listSelector为了去掉选中效果: 
Xml代码 
<ListView android:id="@+id/list" 
android:layout_width
="fill_parent"
android:layout_height
="wrap_content"
android:layout_margin
="20.0dip"
android:cacheColorHint
="@null"
android:listSelector
="@drawable/shape_bg_listview"
android:background
="@drawable/shape_bg_listview"
/>

public class App extends Activity {
private ListView mListView = null;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ArrayList<String> list =new ArrayList<String>();
list.add("1");
list.add("2");
list.add("3");
mListView = (ListView)findViewById(R.id.list);
mListView.setAdapter(new AppAdapter(this,list));
}

class AppAdapter extends BaseAdapter{

Context context;
ArrayList<String> list;
AppAdapter(Context context,ArrayList<String> list){
this.context=context;
this.list=list;
}
@Override
public int getCount() {
// TODO Auto-generated method stub
return list.size();
}

@Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return list.get(position);
}

@Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return position;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
TextView tv;
if(convertView==null){
convertView=LayoutInflater.from(context).inflate(R.layout.simple_item_2, null);
}
tv=(TextView)convertView.findViewById(R.id.name);
tv.setText(list.get(position));
return convertView;
}

}
}
simple_item_2.xml定义如下: 
Xml代码
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width
="fill_parent"
android:layout_height
="wrap_content"
>
<TextView
android:id="@+id/name"
android:textSize
="17.0sp"
android:textColor
="@android:color/black"
android:layout_width
="wrap_content"
android:layout_height
="wrap_content"
android:layout_marginLeft
="20.0dip"
android:layout_alignParentLeft
="true"
android:layout_centerVertical
="true"
>
</TextView>
<ImageView
android:layout_width="wrap_content"
android:layout_height
="wrap_content"
android:layout_marginRight
="20.0dip"
android:src
="@drawable/arrow"
android:layout_alignParentRight
="true"
android:layout_centerVertical
="true"
>
</ImageView>
</RelativeLayout>
