圆角背景的ListView

先定义一张圆角的图片shape_bg_listview.xml

<?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：

<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"/>

代码：

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;    }@Overridepublic int getCount() {// TODO Auto-generated method stubreturn list.size();}@Overridepublic Object getItem(int position) {// TODO Auto-generated method stubreturn list.get(position);}@Overridepublic long getItemId(int position) {// TODO Auto-generated method stubreturn position;}@Overridepublic View getView(int position, View convertView, ViewGroup parent) {// TODO Auto-generated method stubTextView 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 version="1.0" encoding="utf-8"?><RelativeLayoutxmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="fill_parent"android:layout_height="wrap_content"><TextViewandroid: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><ImageViewandroid: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>
