我发现这个教程这表明XML解析,但显示出第一个屏幕上的XML文件中的所有值,我想tomodify这个code,并添加edittextbox这表明我键入编辑文本supose这名I型只值属性编辑文本框2所以在屏幕上显示唯一的ID 2 atttributes并非所有的数据在屏幕上显示我是如何连接的EditText框,数据库等是在屏幕上显示?唯一入选的项目。
i found this tutorial which show xml parsing but is show all values in xml file on 1st screen i want tomodify this code and add edittextbox which show only that value attributes which name i type on edit textbox supose i type in edit text box 2 so is show on screen only ID 2 atttributes not all data show on screen how i connect edittext box with database so is show only selected item on screen??

是的,你可以在下面的code部分:
Yes you can , in the code section below :
for (int i = 0; i < nl.getLength(); i++) {
// creating new HashMap
HashMap<String, String> map = new HashMap<String, String>();
Element e = (Element) nl.item(i);
if(parser.getValue(e, KEY_ID).equals(et.getText().toString())){
// adding each child node to HashMap key => value
map.put(KEY_ID, parser.getValue(e, KEY_ID));
map.put(KEY_NAME, parser.getValue(e, KEY_NAME));
map.put(KEY_COST, "Rs." + parser.getValue(e, KEY_COST));
map.put(KEY_DESC, parser.getValue(e, KEY_DESC));
// adding HashList to ArrayList
menuItems.add(map);
}else{
}
正如你所看到的,你只是检索XML中的ID,并将其与你在编辑文本获得ID。如果它们匹配其添加到HashMap中其他不!
As you can see , you just retrieve the id from XML and compare it to the id you get from the Edit text. If they match add it to the hashmap else dont !
希望这有助于!
