Android ListView填充数据的方法

代码如下：

public class PriceBoard extends LinearLayout { 
  private ListView listView; 
  private List items; 
  private LinearLayout.LayoutParams params; 
  public PriceBoard(Context context, AttributeSet attrs) { 
    super(context, attrs); 
    items = new ArrayList(); 
    this.setOrientation(HORIZONTAL); 
    params = new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT); 
    listView = new ListView(context); 
    listView.setLayoutParams(params); 
    PriceBoardAdapter priceBoardAdapter = new PriceBoardAdapter(context); 
    listView.setAdapter(priceBoardAdapter); 
    addView(listView, params); 
  } 
  public void add(PriceData data){ 
    PriceBoardItem item = new PriceBoardItem(this.getContext(),null); 
    item.setItem(data); 
    items.add(item); 
    params.setMargins(10,0,0,2); 
//    item.setLayoutParams(params); 
  } 
  public PriceBoardItem getItemView(int index){ 
    return (PriceBoardItem)items.get(index); 
  } 
  private class PriceBoardItem extends LinearLayout{ 
    private TextView nameView; 
    private TextView enCodeView; 
    private TextView priceView; 
    private PriceData priceData; 
    public PriceBoardItem(Context context, AttributeSet attrs) { 
      super(context, attrs); 
      this.setOrientation(HORIZONTAL); 
      nameView = new TextView(context); 
      nameView.setTextSize(TypedValue.COMPLEX_UNIT_PX,38); 
      enCodeView = new TextView(context); 
      enCodeView.setTextSize(TypedValue.COMPLEX_UNIT_PX,28); 
      priceView = new TextView(context); 
      priceView.setTextSize(TypedValue.COMPLEX_UNIT_PX,48); 
      priceView.setGravity(Gravity.CENTER); 
      setLayout(); 
    } 
    public TextView getNameView(){ 
      return nameView; 
    } 
    public TextView getEnCodeView(){ 
      return enCodeView; 
    } 
    public TextView getPriceView(){ 
      return priceView; 
    } 
    public PriceData getPriceData(){ 
      return priceData; 
    } 
    private void setLayout(){ 
      LayoutParams p = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT,1); 
      LinearLayout linearLayout = new LinearLayout(getContext()); 
      linearLayout.setOrientation(VERTICAL); 
      linearLayout.addView(nameView,p); 
      linearLayout.addView(enCodeView,p); 
      addView(linearLayout, p); 
 
      p = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT,1); 
      linearLayout = new LinearLayout(getContext()); 
      linearLayout.setOrientation(VERTICAL); 
      linearLayout.addView(priceView,p); 
      addView(linearLayout, p); 
    } 
    public void setItem(PriceData data){ 
      priceData = data; 
    } 
  } 
  private class PriceBoardAdapter extends BaseAdapter{ 
    private Context _context; 
    public PriceBoardAdapter(Context context){ 
      _context = context; 
    } 
    public int getCount(){ 
      return items.size(); 
    } 
    public Object getItem(int position) { 
      return position; 
    } 
 
    @Override 
    public long getItemId(int position) { 
      return position; 
    } 
 
    @Override 
    public View getView(int position, View convertView, ViewGroup parent) { 
      PriceBoardItem view = getItemView(position); 
      PriceData data = ((PriceBoardItem) items.get(position)).getPriceData(); 
      view.getNameView().setText(data.getName()); 
      view.getEnCodeView().setText(data.getEnCode()); 
      view.getPriceView().setText(String.valueOf(data.getPrice())); 
      convertView = view; 
      return convertView; 
    } 
  }

调用：

PriceBoard priceBoard = new PriceBoard(context,null); 
priceData = new PriceData(); 
priceData.setName("现货白银"); 
priceData.setEnCode("Ag"); 
priceData.setPrice(4006); 
priceBoard.add(priceData); 
priceData = new PriceData(); 
priceData.setName("现货铜"); 
priceData.setEnCode("Cu"); 
priceData.setPrice(43895); 
priceBoard.add(priceData); 
priceData = new PriceData(); 
priceData.setName("现货镍"); 
priceData.setEnCode("Ni"); 
priceData.setPrice(43895); 
priceBoard.add(priceData); 
addView(priceBoard);

效果：
