通过继承BaseAdapter写一个子类，可以创建自定义列表视图：
| public class MyListAdapter extends BaseAdapter { private LayoutInflater mInflater;//声明一个LayoutInflater类变量 private Context mContext;//声明一个Context类变量 private List<Map<String,String>> mitem;//声明一个元素为<Map<String,String>>类型的List对象，存储testitem的值 private Map<String,Integer> selectedtestItem = new HashMap<String,Integer>();//声明一个Map对象，用HashMap来实现 private List<Map<String, String>> mData; // 声明一个元素为<Map<String,String>>类型的List对象，存储的editTex值 private Map<String, String> editorValue = new HashMap<String, String>();//声明一个Map对象，用HashMap来实现 private List<Map<String,String>> mParameter;//用于保存parameter_edit参数值 //private static HashMap<Integer, Boolean> isSelected;//声明一个HashMap<Integer,Boolean>类型的变量 private String[] testItems; private String promptForSpinner[] = {"0","1","2","3","4","5","6","7","8","9","10","11","12","13","14","15","16","17","18","19"};
public MyListAdapter(Context context,String[] testItems) {//构造函数 // TODO Auto-generated constructor stub mInflater = LayoutInflater.from(context);//获得LayoutInflater this.testItems = testItems; puttestitemName(); } private void puttestitemName() { for (String str : promptForSpinner) { selectedtestItem.put(str,0); } /*for(int i=0;i<20;i++){ selectedtestItem.put("list_item_Name", 0);//allValues保存以项目名称为键值、0为数值的一系列成对的数据 }*/ } public void setData( List<Map<String, String>> data) {//初始化Lisr类型的对象 mData = data; mParameter=data; init(); } private void init() {//实现初始化List类型的对象的方法 editorValue.clear(); /*isSelected = new HashMap<Integer, Boolean>(); if (mData != null) { for (int i = 0; i < mData.size(); i++) { isSelected.put(i, false); } }*/ } public Map<String,Integer> getSelectedtestItem() { return selectedtestItem; }
