我想更改表格列表视图上的特定图像，当用户单击列表视图的任何图像视图然后打开对话框时，如果用户单击确定按钮确定对话框，则应更改特定图像。我已经创建了代码，但它不能正常工作。
public void Display_Description(String get_Desc) {
setDESCRIPTION = get_Desc;
TableLayout tbl = new TableLayout(Job_Description.this);
mylist = new ArrayList<String>();
Document doc = XMLfunctions.XMLfromString(JobSearch.line);
// Parent node is JOB
NodeList nodes = doc.getElementsByTagName("JOB");
for (int i = 0; i < nodes.getLength(); i++) {
Element e = (Element) nodes.item(i);
pass_value.add(XMLfunctions.getValue(e, "id"));
if (!("null").equals(XMLfunctions.getValue(e, "location"))) {
mylist.add(XMLfunctions.getValue(e, "location"));
city_name.add(XMLfunctions.getValue(e, "location"));
} else {
mylist.add(" ");
}
if (!("null").equals(XMLfunctions.getValue(e, "title"))) {
mylist.add(XMLfunctions.getValue(e, "title"));
business_name.add(XMLfunctions.getValue(e, "title"));
} else {
mylist.add(" ");
}
if (!("null").equals(XMLfunctions.getValue(e, "state"))) {
mylist.add(XMLfunctions.getValue(e, "state"));
state_name.add(XMLfunctions.getValue(e, "state"));
} else {
mylist.add(" ");
}
if (!("null").equals(XMLfunctions.getValue(e, "company"))) {
mylist.add(XMLfunctions.getValue(e, "company"));
company_name.add(XMLfunctions.getValue(e, "company"));
} else {
mylist.add(" ");
