我有一个带有 onItemClickListener 的列表视图和一个带有复选框的自定义适配器。该复选框还有一个 onClickListener。但是我对适配器的数组列表没有显示文本。谢谢！
这是我的代码：
public class Search_list extends Activity {
static String str1 = "v1", str2 = "v2";
String s, item;
static int spnr, range1, range2;
private CarHelper dbcarhelper = null;
private Cursor ourCursor;
CarHelper h = null;
List<String[]> names2 = null;
ListView LV;
MyCustomAdapter dataAdapter = null;
CheckBox cb;
List<String[]> mlist = new ArrayList<String[]>();
TextView tv1;
// String[] stg1;
ArrayList<String> stg1;
ArrayList<String> ids_pos = new ArrayList<String>();
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.search_list);
LV = (ListView) findViewById(R.id.list);
// tv1 = (TextView) findViewById(R.id.noRec);
// tv1.setVisibility(View.GONE);
// get_list();
dbcarhelper = new CarHelper(this);
dbcarhelper.createDatabase();
dbcarhelper.openDataBase();
if (s != null) {
startManagingCursor(ourCursor);
}
System.out.println("onCreate = |" + spnr + "|");
if (spnr == 1) {
System.out.println("Make spnr= |" + spnr + "|");
byMakeModel();
}
if (spnr == 2) {
System.out.println("Budget spnr= |" + spnr + "|");
byBudgetFuel();
}
fill_list();
}
public void SetId(String s1, String s2, int s) {
System.out.println("SetMake spnr= |" + spnr + "|");
System.out.println("SetMake s= |" + s + "|");
str1 = s1;
str2 = s2;
spnr = s;
System.out.println("SetMake aftr spnr= |" + spnr + "|");
}
public void SetBudgetFuel(String s1, String s2, int s, int r1, int r2) {
System.out.println("SetBudget spnr= |" + spnr + "|");
System.out.println("SetBudget s= |" + s + "|");
System.out.println("SetBudget r1= |" + r1 + "|");
System.out.println("SetBudget r2= |" + r2 + "|");
str1 = s1;
str2 = s2;

range1 = r1;
