首先在XML文件在创建ListView；

然后再在另一个XML文件中创建TextView和ImageView；

Viewactivity

public class Viewactivity  extends Activity {    private List<Data> dataList = new ArrayList<Data>();    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);        setContentView(R.layout.listview);        getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.title);        intiDatas();        //设置一个adpter适配器        dataAdapter adapter = new dataAdapter(Viewactivity.this,R.layout.data_list , dataList);        ListView listView = (ListView) findViewById(R.id.list_view);        //将构置好的适配器对象传递进去        listView.setAdapter(adapter);        //List中的item按键响应        listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {            @Override            public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {                Data data = dataList.get(i);                Toast.makeText(Viewactivity.this, data.getDataName(),Toast.LENGTH_SHORT).show();            }        });    }    private void intiDatas() {        Data data1 = new Data("data1", R.drawable.data1);        dataList.add(data1);        等等.....    }}

Adapter

=======================================================================================

public class dataAdapter extends ArrayAdapter<Data> {    private int resourceId;    public dataAdapter(Context context, int dataResourceId, List<Data> datas){        super(context,dataResourceId,datas);        resourceId = dataResourceId;    }    //getView方法是在List中被显示在屏幕中使用    @Override    public View getView(int position, View convertView, ViewGroup parent) {        //使用getItem来获取当前的实例        //获取的是data的String和data图片的ID，在实例化data的时候用了R.id.data1        //实际上R.id.data1是该图片独立的一个INT类型的整数        Data data = getItem(position);        ViewHolder viewHolder;        View view;        //当convertView为空则用layoutInflater去加载布局，否则直接使用convertView        if(convertView==null){            //layoutInflater加载我们传入的布局，即是data_list.xml这个文件的ID            view = LayoutInflater.from(getContext()).inflate(resourceId,null);            viewHolder = new ViewHolder();            //设置图片和名字            viewHolder.dataImage = (ImageView) view.findViewById(R.id.data_image);            viewHolder.dataName = (TextView) view.findViewById(R.id.data_list);            view.setTag(viewHolder);        }else {            view = convertView;            viewHolder = (ViewHolder) view.getTag();        }        viewHolder.dataImage.setImageResource(data.getImgID());        viewHolder.dataName.setText(data.getDataName());        return view;    }    //ViewHolder用于对控件的实例进行储存.    class ViewHolder{        ImageView dataImage;        TextView dataName;    }}
