直接上代码吧

public class MainActivity extends ActionBarActivity {private ListView lv;private List<Map<String, Object>> list = new ArrayList<Map<String, Object>>();@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);lv = (ListView) findViewById(R.id.lv_list);initData();lv.setAdapter(new MyAdapter());}private void initData() {Map<String, Object> map = new HashMap<String, Object>();map.put("img", R.drawable.su01);map.put("title", "0");map.put("button", "0");list.add(map);map = new HashMap<String, Object>();map.put("img", R.drawable.su02);map.put("title", "1");map.put("button", "1");list.add(map);map = new HashMap<String, Object>();map.put("img", R.drawable.su03);map.put("title", "2");map.put("button", "2");list.add(map);}class MyAdapter extends BaseAdapter {@Overridepublic int getCount() {return list.size();}@Overridepublic Object getItem(int position) {return null;}@Overridepublic long getItemId(int position) {return 0;}@Overridepublic View getView(int position, View convertView, ViewGroup parent) {convertView = View.inflate(MainActivity.this,R.layout.list_item_layout, null);ImageView mImageView = (ImageView) convertView.findViewById(R.id.imageview);TextView mTextView = (TextView) convertView.findViewById(R.id.textview);Button mButton = (Button) convertView.findViewById(R.id.button);mImageView.setImageResource((Integer) list.get(position).get("img"));mTextView.setText(list.get(position).get("title").toString());mButton.setText(list.get(position).get("button").toString());return convertView;}}}

再加上两个布局文件

<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">    <ListView        android:id="@+id/lv_list"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:listSelector="@android:color/transparent"        android:divider="@android:color/transparent"        android:layout_marginTop="40dp" /></RelativeLayout>

<?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"    android:orientation="horizontal" >    <ImageView         android:id="@+id/imageview"        android:layout_width="50dip"        android:layout_height="50dip"        />    <TextView         android:id="@+id/textview"        android:layout_width="wrap_content"        android:layout_height="match_parent"        android:paddingTop="8dip"        android:textSize="20sp"        /><Button     android:id="@+id/button"    android:layout_width="wrap_content"        android:layout_height="wrap_content"    /></LinearLayout>

效果如下
